Current Good Manufacturing Practice in Manufacturing, Packing, or 
Holding Dietary Ingredients and Dietary Supplements

AGENCY: Food and Drug Administration, HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is proposing current 
good manufacturing practice (CGMP) regulations for dietary ingredients 
and dietary supplements. The proposed rule would establish the minimum 
CGMPs necessary to ensure that, if you engage in activities related to 
manufacturing, packaging, or holding dietary ingredients or dietary 
supplements, you do so in a manner that will not adulterate and 
misbrand such dietary ingredients or dietary supplements. The 
provisions would require manufacturers to evaluate the identity, 
purity, quality, strength, and composition of their dietary ingredients 
and dietary supplements. The proposed rule is one of many actions 
related to dietary supplements that we (FDA) are taking to promote and 
protect the public health.

I. Background

A. Dietary Supplement Health and Education Act (DSHEA)

    DSHEA (Pub. L. 103-417) was signed into law on October 25, 1994. 
DSHEA, among other things, amended the Federal Food, Drug, and Cosmetic 
Act (the act) by adding section 402(g) (21 U.S.C. 342(g)). Section 
402(g)(2) of the act provides, in part, that the Secretary of Health 
and Human Services (the Secretary) may by regulation prescribe good 
manufacturing practices for dietary supplements. Such regulations shall 
be modeled after CGMP regulations for food and may not impose standards 
for which there is no current and generally available analytical 
methodology. No standard of CGMP may be imposed unless such standard is 
included in a regulation issued after notice and opportunity for 
comment in accordance with 5 CFR chapter V.
    Congress enacted DSHEA to ensure consumers' access to safe dietary 
supplements. In the findings accompanying DSHEA, Congress stated that 
improving the health status of U.S. citizens is a national priority and 
that the use of dietary supplements may help prevent chronic diseases 
and maintain good health (Ref. 1). If dietary supplements are 
adulterated because they contain contaminants (such as filth), because 
they do not contain the dietary ingredient they are represented to 
contain (for example, a product labeled as vitamin C that actually 
contains niacin), or because the amount of the dietary ingredient 
thought to provide a health benefit (for example, folic acid to reduce 
the risk of neural tube defects or calcium in an amount to reduce the 
risk of osteoporosis) is not actually present in the supplement, then 
the consumer may suffer harm or may not obtain the purported health 
benefit from their consumption. CGMP regulations for dietary 
ingredients and dietary supplements will help to ensure that the 
potential health benefits that Congress identified as the basis for 
DSHEA are obtained and that consumers receive the dietary ingredients 
that are stated on the product label.
    DSHEA directed the President to appoint a Commission on Dietary 
Supplement Labels (the Commission) to consider several issues under 
DSHEA needing clarification. The Commission was to conduct a study on, 
and provide recommendations for, the regulation of label claims and 
statements for dietary supplements, including the use of literature in 
connection with the sale of dietary supplements and procedures for the 
evaluation of such claims. In making its recommendations, the 
Commission was to evaluate how best to provide truthful, scientifically 
valid, and nonmisleading information to consumers so that such 
consumers could make informed and appropriate health care choices for 
themselves and their families. The Commission's report (Ref. 80) states 
that the Commission supports the efforts of industry and FDA to develop 
appropriate CGMPs for dietary supplements. Guidance on the type of 
information that a responsible manufacturer should have to substantiate 
statements of nutritional support and safety is also included in the 
Commission's report. The Commission's report states that the 
substantiation files should include assurance that CGMPs were followed 
in the manufacture of the product.

B. The Advance Notice of Proposed Rulemaking

    On November 20, 1995, representatives of the dietary supplement 
industry submitted to FDA an outline for CGMP regulations for dietary 
supplements and dietary supplement ingredients. We evaluated the 
outline and determined that it provided a useful starting point for 
developing CGMP regulations. Nonetheless, we believed that the industry 
outline did not address certain issues that should be considered when 
developing a proposed rule on CGMPs for dietary ingredients and dietary 
supplements. For example, the industry outline did not address the need 
for specific controls for automatic, computer-controlled or assisted 
systems.
    In addition to identifying a number of issues that were not 
included in the industry outline but on which we wanted public comment, 
we also recognized that other interested parties, such as consumers, 
other industry segments who had not participated in developing the 
outline, and the health care community should have an opportunity to 
provide comments on CGMPs for dietary supplements before we developed a 
proposal. Therefore, in the Federal Register of February 6, 1997 (62 FR 
5700), we issued an advance notice of proposed rulemaking (ANPRM) 
asking for comments on whether to institute rulemaking to develop CGMP 
regulations for dietary ingredients and dietary supplements and what 
would constitute CGMP regulations for these products.
    The ANPRM contained the entire text of the industry outline. We 
also asked nine questions (which we discuss later in section II.B of 
this document) in the ANPRM. The questions focused on issues that the 
industry outline did not address such as those issues noted above. We 
received approximately 100 letters in response to the ANPRM. Each of 
those letters contained one or more comments. The comments came from 
consumers, consumer advocacy groups, health care professionals, health 
care professional organizations, industry, and industry trade 
associations. The majority of comments responded both to the nine 
questions we asked in the ANPRM and on certain provisions in the 
industry outline. We also address the comments on the nine questions in 
section II.B of this document. We discuss significant comments about 
certain provisions in the industry outline in our discussion of related 
proposed requirements.
    Included with its comments to the ANPRM, the United States 
Pharmacopeia (USP) submitted a copy of its general chapter, 
``Manufacturing Practices for Nutritional Supplements,'' (Ref. 2) and 
in March/April 2002, USP proposed revisions to this general chapter to 
introduce provisions pertaining to botanical preparations (Ref. 82). In 
February 2000, we received a copy of the National Nutritional Foods 
Association's (NNFA) ``NNFA Good Manufacturing Practice in 
Manufacturing, Packing, or Holding Dietary Supplements'' (Ref. 3). We 
found that the industry outlines published in the ANPRM, the USP 
manufacturing practices, and the NNFA standards were useful in 
developing this proposed rule. We included certain provisions found in 
these outlines in this CGMP proposed rule. These three outlines 
indicate that dietary ingredient and dietary supplement manufacturers 
already recognize that there are basic, common steps needed to 
manufacture a dietary ingredient or dietary supplement that is not 
adulterated although, as established in the regulatory impact analysis, 
a large percentage of manufacturers do not follow a good manufacturing 
model. For example, these practices include requirements for:
    [sbull] Designing and constructing physical plants that facilitate 
maintenance, cleaning, and proper

[[Page 12160]]

manufacturing operations or to prevent mixup between different raw 
materials and products;
    [sbull] Establishing a quality control unit;
    [sbull] Establishing and following written procedures for:
    1. Maintaining and cleaning equipment and utensils;
    2. Receiving, testing, or examining materials received and testing 
of finished product;
    3. Using master and batch control records;
    4. Handling consumer complaints; and
    5. Maintaining records for laboratory tests, production control, 
distribution, and consumer complaints.
    Based on the ANPRM, the comments that we received in response to 
the ANPRM, our outreach activities (which we discuss below), and our 
own knowledge and expertise about CGMPs for foods, drugs, cosmetics, 
devices, and biologics, we are proposing to establish these CGMP 
regulations for dietary ingredients and dietary supplements. The 
proposed regulations would impose requirements for: (1) Personnel, (2) 
physical plants, (3) equipment and utensils, (4) production and process 
controls, (5) holding and distributing, (6) consumer complaints related 
to good manufacturing practices, and (7) records and recordkeeping.

C. Industry and Consumer Outreach

    During 1999, we conducted a number of outreach activities related 
to dietary supplements. We held several public meetings to obtain input 
from the public on developing our overall strategy for achieving 
effective regulation of dietary supplements, which could include 
establishing CGMP regulations. We also held public meetings focused 
specifically on CGMPs and the economic impact that any CGMP rule for 
dietary ingredients and dietary supplements may have on small 
businesses. Additionally, FDA staff toured several dietary supplement 
manufacturing firms to better understand the manufacturing processes 
and practices that potentially would be subject to a CGMP regulation 
for dietary ingredients and dietary supplements. Each of these 
activities contributed to our knowledge about the industry.
1. Dietary Supplement Strategic Plan Meetings
    We held public meetings on June 8 and July 20, 1999, to collect 
stakeholder comments on the development of our overall strategy for 
achieving effective regulation of dietary supplements. We designed the 
meetings to provide an opportunity for public comment on both the 
activities we should undertake as part of an overall strategy and the 
prioritization of those activities. In the notices for these meetings, 
we identified the development of CGMPs for dietary supplements as one 
activity that should be considered in an overall strategy.
    During and after the strategic meetings, we received comments from 
consumers, consumer advocacy groups, health care professionals, health 
care professional organizations, industry, and industry trade 
associations. The comments addressed a wide range of activities related 
to regulating dietary supplements. (These comments can be seen at our 
Dockets Management Branch (see ADDRESSES) in docket number 99N-1174.) 
The comments generally identified the development of CGMP regulations 
as a high priority activity that should be included in any FDA 
strategic plan for regulating dietary supplements. Some comments that 
addressed the development of CGMPs are summarized as follows:
    [sbull] It would be useful to industry to have FDA establish CGMPs 
especially for small and intermediate-size firms that are not clear on 
what they should be doing;
    [sbull] CGMPs would establish a level playing field for industry, 
which would help prevent irresponsible firms from making and selling 
adulterated products;
    [sbull] CGMPs should be able to accommodate a wide variety of 
firms, that is, small and large firms that manufacture a wide array of 
different types of products and ingredients;
    [sbull] CGMPs should ensure that consumers get dietary supplements 
with the strength and the purity that consumers expect;
    [sbull] CGMPs should ensure that every dietary supplement on the 
market has the safety, identity, purity, quality, and strength it 
purports in the label to possess;
    [sbull] CGMPs should include ingredient identity testing and other 
testing;
    [sbull] CGMPs should ensure that dietary supplements are produced 
using a master formula procedure and produced in a sanitary facility;
    [sbull] CGMPs should require that manufacturers have documented 
evidence that their manufacturing process is under control on a 
consistent basis;
    [sbull] CGMPs should require manufacturers to test dietary 
ingredients, particularly imported botanicals, for heavy metals, 
pesticides, and industrial contaminants;
    [sbull] CGMPs should require expiration dating and testing for 
dissolution and bioequivalence;
    [sbull] CGMPs should require that companies report adverse 
reactions; and
    [sbull] CGMPs should include guidance on testing for ingredient 
identity and adulteration with toxic substances.
2. Small Business Outreach Meetings
    We held public meetings on July 12, September 28, and October 21, 
1999, to collect information from industry and others that would help 
us to understand the economic impact on small businesses of CGMP 
regulations for dietary supplements. Transcripts of these public 
meetings (docket number 96N-0417, ``Development of Strategy for Dietary 
Supplements'') are available at our Dockets Management Branch or 
electronically at http://www.fda.gov/ohrms/dockets/dockets/96n0417/
tr00001.pdf.
 Public comments from small businesses included both 

support of and concern for CGMP regulations. Small businesses expressed 
concerns about the cost and the time involved in complying with any 
rule that contains the following requirements:
    [sbull] Conducting tests to determine identity, purity, quality, 
strength, and composition of dietary ingredients and dietary 
supplements;
    [sbull] Maintaining written procedures and records documenting that 
procedures are followed; and
    [sbull] Providing data that support expiration dating.
    Public comments from small business expressed support for dietary 
supplement CGMP regulation. Some small businesses (1 with 15 employees) 
commented that they have CGMPs in place with written procedures 
tailored to the size of their operations. One small business with sales 
under $1 million commented that their plant materials received in fresh 
form are identified onsite by a botanist, and when the onsite botanist 
is not able to confirm identity, the plant material is sent to an 
outside laboratory that conducts chemical analysis to confirm identity.
3. Site Visits to Dietary Supplement Manufacturing Firms
    During the summer and fall of 1999, we visited eight dietary 
supplement manufacturing firms. These visits included firms that: (1) 
Manufacture a vitamin using a fermentation process; (2) grind, sift, 
blend, and otherwise treat raw agricultural commodities (e.g., 
botanicals); (3) manufacture dietary ingredients for use in 
manufacturing dietary supplement tablets, capsules, softgels, and 
powders; (4) manufacture dietary supplements for packaging and labeling 
by others; and (5) manufacture, package, and label dietary supplements 
under their own and others' labels. The

[[Page 12161]]

firms varied in size and were located in several parts of the country.
    We found an array of manufacturing, packaging, and holding 
practices in the firms. The practices included the following:
    [sbull] Using CGMPs similar to those included in the ANPRM;
    [sbull] Using automatic systems to quarantine, segregate, approve, 
and release inventory;
    [sbull] Following written procedures;
    [sbull] Having quality control units with the responsibility and 
authority outlined in the ANPRM;
    [sbull] Performing one or more tests on dietary ingredients and 
dietary supplements to determine the identity, purity, quality, 
strength, and composition;
    [sbull] Verifying the reliability of suppliers' certifications; and
    [sbull] Documenting and maintaining records for certain procedures, 
such as master and batch production, quality control and laboratory 
operations, distribution, and processing consumer complaints.

D. Food Advisory Committee Report

    In February 1998, the Food Advisory Committee (FAC) established a 
Dietary Supplement Working Group to consider what constitutes adequate 
testing for identity of different dietary ingredients and what records 
are necessary to demonstrate that CGMPs are maintained throughout the 
manufacturing and distribution process. The working group issued a 
report that discussed the selection of the most appropriate and 
reliable identity test and the general principles for consideration in 
setting performance standards for such tests (Ref. 4). The report also 
identified the types of records that would be necessary to demonstrate 
that CGMPs are maintained throughout the manufacturing and distribution 
process. On June 25, 1999, the working group presented its report, in 
draft form, during an FAC public meeting. We received public comments 
during and after the June 25, 1999, public meeting.
    Although this proposal does not address dietary ingredient identity 
testing in the same detail as the working group's report, we considered 
the report in developing requirements for identity testing and CGMP 
records requirements in this proposal. The working group's report may 
be useful in developing industry guidance to supplement a CGMP 
regulation for dietary ingredients and dietary supplements. We discuss 
dietary ingredient and dietary supplement identity testing and 
recordkeeping for CGMP proposed requirements in more detail later in 
this document.

E. FDA's Decision To Propose a Rule

    This proposed regulation, which sets forth proposed CGMPs for 
dietary ingredients and dietary supplements, is part of our overall 
strategy for regulating dietary supplements in a manner that promotes 
and protects the public health. Before drafting the proposal, FDA 
considered public comment in response to the ANPRM and to public 
meetings, observations at site visits to dietary supplement 
manufacturers, and advisory group reports. In drafting this proposal, 
FDA used, in part, the industry coalition outline that was published as 
an ANPRM (62 FR 5700) in which the industry adopted broad provisions 
beyond those found in part 110 (21 CFR part 110). FDA's purpose at this 
proposed rule stage is to present a broad enough scope so that it may 
receive comment on the depth and breadth of what should be considered 
by the agency in developing a final rule. Our intent is to provide the 
proper balance of regulation so that dietary ingredients and dietary 
supplements are manufactured in a manner to prevent adulteration using 
recognized scientific principles and both industry and consumer 
expectations that are reasonable and appropriate. Therefore, FDA seeks 
comment on whether each of the proposed provisions are necessary to 
ensure the safety and quality of dietary ingredients and dietary 
supplements and whether they are adequate to protect the public health. 
In addition, we seek comment on whether there are certain provisions 
that are not proposed but that may be necessary. Comments should 
include justification for why provisions may or may not be necessary, 
including supporting data where appropriate. If comments assert that 
certain provisions are not necessary, comments should include an 
explanation on how, in the absence of the requirement, one can ensure 
that there would be adequate protection of the public health when there 
is risk of adulteration. Comments also should address whether the gains 
to consumers in product safety and quality are warranted. Moreover, 
assuming that this proposal does advance the public health, comments 
should address whether there is any reason to apply different 
requirements, including greater or lesser requirements on small firms 
as compared to larger firms and the rationale for doing so. Finally, 
comments should address the agency's legal authority to issue these 
regulations.
    In deciding whether to propose CGMP regulations for dietary 
supplements, we asked ourselves:
    [sbull] Why Are CGMP regulations needed?
    [sbull] How will CGMP regulations take into account technical 
feasibility? and
    [sbull] How can FDA help industry achieve compliance with CGMPs?
1. Why Are CGMPs Needed?
    CGMP regulations for dietary ingredients and dietary supplements 
are necessary to promote and protect the public health. In addition, 
CGMP regulations would benefit consumers economically and would benefit 
industry.
    a. CGMPs help protect the public health. The dietary supplement 
industry is one of the fastest growing product areas that FDA 
regulates. In 1999, Prevention magazine conducted a survey entitled 
``Consumer Use of Dietary Supplements'' (Ref. 5). The survey used data 
from telephone interviews with a nationally-representative sample of 
2,000 adults living in households with telephones in the continental 
United States. The telephone interviews were done in April and May, 
1999. Using population estimates based on the Census Bureau's March 
1998 Current Population Survey Estimates, the survey stated that 
approximately 186,014,712 adults live in the households with telephones 
in the United States and that an estimated 158.1 million of these 
Americans in households with telephones use dietary supplement 
products. These consumers spend approximately $8.5 billion a year on 
dietary supplements. The survey also found that:
    [sbull] Only 41 percent of the surveyed consumers who use vitamins 
and minerals think they are very safe and only 50 percent think they 
are somewhat safe;
    [sbull] Only 24 percent of the surveyed consumers who use herbal 
products think they are very safe; and only 53 percent think they are 
somewhat safe; and
    [sbull] Twelve percent of the surveyed consumers who have used 
dietary supplements say they have experienced side effects or adverse 
reactions from their use of dietary supplements.
    The survey also found strong public support for increased 
Government regulation of dietary supplements; 74 percent of the 
surveyed consumers reported that they think that the Government should 
be more involved in ensuring that these products are safe and do what 
they claim to do.
    However, unlike other major product areas, there are no FDA 
regulations that

[[Page 12162]]

are specific to dietary ingredients and dietary supplements that 
establish a minimum standard of practice for manufacturing, packaging, 
or holding. The absence of minimum standards has contributed to the 
adulteration and misbranding of dietary ingredients and dietary 
supplements by contaminants or because manufacturers do not set and 
meet specifications for their products, including specifications for 
identity, purity, quality, strength, and composition. Thus, CGMP 
regulations are necessary to protect the public health because a CGMP 
rule would establish a minimum standard of practice for manufacturing, 
packaging, and holding dietary ingredients and dietary supplements.
    The following examples illustrate the wide range of dietary 
ingredient and dietary supplement adulteration caused by manufacturing, 
packaging, or holding practices. The examples, although not exhaustive, 
demonstrate why CGMPs are necessary to protect public health:
    [sbull] In 1997, we received an adverse event report (AER) 
regarding a young woman who had taken a dietary supplement and 
experienced a life-threatening abnormal heart function (Ref. 6). We 
investigated the AER and determined that the dietary supplement the 
woman consumed contained Digitalis lanata, a plant that can cause life-
threatening heart reactions (Refs. 6 through 10). We found D. lanata in 
samples of raw material labeled ``plantain'' that was a dietary 
ingredient in one of the dietary supplement products used by this woman 
(Ref. 6). A nationwide listing of manufacturers indicated that 183 
firms may have used the contaminated dietary ingredient in dietary 
supplements. The proposed CGMP regulations, had they been in effect, 
would have required identity and purity tests of dietary ingredients 
and dietary supplements and would likely have prevented the use of the 
D. lanata in these dietary supplements.
    [sbull] In 1998, the American Herbal Products Association (AHPA) 
surveyed its members about commonly adulterated botanicals and methods 
useful in detecting adulteration in botanicals (Ref. 11). AHPA members 
identified 43 botanicals, including D. lanata contaminated plantain, 
that are commonly adulterated with contaminants, the common adulterant 
for each botanical, and a method for identifying the adulterant. For 
example, aflatoxin and mycotoxin (toxic compounds produced by certain 
molds) are known to contaminate certain herbal and botanical dietary 
supplements (Refs. 11 through 14). Under this proposed rule, a 
manufacturer would have to establish specifications for botanicals that 
may contain toxic compounds and conduct testing to ensure that there 
are not toxic compounds present that may adulterate the dietary 
ingredient or dietary supplement.
    [sbull] We have found manufacturers using nonfood-grade chemicals 
to manufacture dietary supplements (Ref. 15). The proposed rule would 
require that manufacturers establish specifications for components used 
in manufacturing and also would require manufacturers to establish and 
follow laboratory control procedures that include criteria for 
establishing appropriate specifications. The proposal would further 
require manufacturers to conduct testing to confirm that their 
specifications are met. These requirements, if finalized, would ensure 
that manufacturers establish and use appropriate criteria, such as 
using food-grade rather than industrial-grade chemicals, and would 
ensure that manufacturers conduct testing to confirm that food-grade 
chemicals were received from the supplier.
    [sbull] Also during inspections, we have found insanitary 
conditions in physical plants where dietary ingredients or dietary 
supplements were manufactured, packaged, or held (Ref. 16). Pest 
infestation, building and equipment defects, and leaking pipes that 
drip onto dietary supplements are examples of insanitary conditions 
that we have found that may lead to product adulteration and could 
cause consumer illnesses and injuries. The proposed rule would require 
a manufacturer, packager, or holder to maintain its physical plant used 
for these activities in a sanitary condition.
    [sbull] In the past, we have been involved in the recall of dietary 
supplements contaminated with lead (Ref. 17), salmonella (Ref. 18), 
Klebsiella pneumonia (Ref. 19), botulism (Ref. 20), and glass (Ref. 
21). These contaminants can cause serious illness or injury and, in the 
case of lead, may result in chronic irreversible cognitive defects in 
children and progressive renal failure in adults. The proposed rule 
would require dietary ingredients and dietary supplements to be 
manufactured, packaged, and held in a manner that prevents 
adulteration, including adulteration by the contaminants such as those 
described.
    [sbull] We also have been involved in recalls for super- and 
subpotent dietary supplements. Recalls of superpotent dietary 
supplements have included the following dietary ingredients: Vitamin A 
(Ref. 22), vitamin D (Ref. 23), vitamin B6 (Ref. 24), and selenium 
(Ref. 25). Each of these dietary supplements contained dietary 
ingredient levels that could have caused serious illness or injury. 
Illnesses or injuries such as nausea, vomiting, liver damage, and heart 
attack were reported from superpotent niacin at an average level of 452 
milligrams (mg) niacin, well above the upper limit for adults of 45 mg 
daily (Ref. 26). Recalls for subpotent dietary supplements have 
included a recall of folic acid because the dietary supplement 
contained 34 percent of the declared level (Ref. 27). Such a product 
would be misbranded under section 403 of the act (21 U.S.C. 343). 
Folate plays a well-documented and important role in reducing the risk 
of neural tube defects. Neural tube birth defects, primarily spina 
bifida and anencephaly, cause serious lifetime debilitating injuries 
and disabilities, and even death. Thus, use of subpotent folic acid by 
women who are or may become pregnant may result in increased risk of 
having a child with a neural tube defect. The proposed rule would 
require manufacturers to establish specifications for the dietary 
supplement the manufacturer makes and then meet those specifications. 
Therefore, if the proposed rule is finalized, if the label for a folic 
acid supplement declares that the dietary supplement contains a certain 
level of folic acid, the folic acid supplement must actually contain 
that level, or we would consider the folic acid supplement to be 
adulterated under section 402(g) of the act.
    [sbull] Other recalls have been necessary because of undeclared 
ingredients, including color additives (Refs. 28 and 29), lactose (Ref. 
30), and sulfites (Ref. 31). Undeclared ingredients, such as color 
additives, lactose, and sulfites, may cause potentially dangerous 
reactions in susceptible persons (Ref. 32). The proposed rule would 
require manufacturers to verify that the correct labels have been 
applied to dietary ingredients and dietary supplements produced. The 
master manufacturing record would have to identify each ingredient 
required to be declared on the ingredient list under section 403 of the 
act.
    [sbull] A study found that dietary ingredient content varied 
considerably from the declared content (Ref. 33). The study examined 
ephedra alkaloids in 20 herbal dietary supplements containing ephedra 
(Ma Huang) to determine their ephedra alkaloid content. This study 
found that norpseudoephedrine was often present in the ephedra dietary 
supplements. The study also observed significant lot-to-lot variations 
in alkaloid content for four products,

[[Page 12163]]

including one product that had lot-to-lot variations of ephedrine, 
pseudoephedrine, and methylephedride that exceeded 180 percent, 250 
percent, and 1,000 percent, respectively. Half of the products tested 
differed in their label claims for ephedra alkaloid content and their 
actual alkaloid content. In some cases, the discrepancy exceeded 20 
percent. One product did not have any ephedra alkaloids. Lot-to-lot 
variation in dietary ingredients is a public health problem 
particularly because conditions of use recommended or suggested in the 
labeling of dietary supplements are presumably based on the dietary 
supplement containing a certain amount of the dietary ingredient. If 
the dietary supplement contains more or less than the amount that the 
manufacturer represents, then the consumer does not receive the 
potential health benefit from the dietary supplement or is exposed to 
an amount that could present risk of injury or illness. The proposed 
rule would require manufacturers to establish controls, including 
master manufacturing and batch production records to ensure that they 
use the correct amount of the dietary ingredient to produce the dietary 
supplement, and that they apply the correct label to the dietary 
supplement.
    [sbull] A private company analyzed a sample of dietary supplements 
and found that some dietary supplements did not contain the dietary 
ingredients claimed on the label (Ref. 34). The study found that 25 
percent of gingko biloba products, 20 percent of saw palmetto, 33 
percent of glucosamine, chrondroitin and combined glucosamine/
chondroitin, and 50 percent of SAMe did not contain the dietary 
ingredients claimed in their product labels. The proposed rule would 
require manufacturers to establish and meet specifications for the 
identity, purity, quality, strength, and composition of dietary 
supplements.
    Given the wide range of public health concerns presented by the 
manufacturing, packaging, and holding practices for dietary ingredients 
and dietary supplements, a comprehensive system of controls is 
necessary to prevent adulteration and misbranding. CGMPs are intended 
to establish such a comprehensive system. Manufacturers who operate in 
accordance with CGMPs would be less likely to distribute adulterated 
and misbranded dietary ingredients or dietary supplements than those 
who do not meet the requirements. Quality assurance will maximize the 
probability that unadulterated dietary supplements will reach the 
marketplace.
    Establishing CGMP regulations for dietary supplements is only part 
of our broad science-based regulatory program for dietary supplements 
that is necessary to give consumers a high degree of confidence in the 
safety, composition, and labeling of dietary supplements. Aside from 
our CGMP efforts, we have taken other steps to protect the public 
health, such as:
    [sbull] Reviewing claim notifications under section 403(r)(6) of 
the act to identify unlawful claims;
    [sbull] Reviewing new dietary ingredient notifications to ensure 
that new dietary ingredients are reasonably expected to be safe under 
section 413 of the act (21 U.S.C. 350b);
    [sbull] Evaluating the nutrition labeling of dietary supplements;
    [sbull] Monitoring, through AERs voluntarily submitted to FDA, the 
occurrence of adverse events to identify potentially unsafe products; 
and
    [sbull] Taking compliance actions against products that are 
adulterated or misbranded.
    The CGMP regulation, if finalized, would, along with our other 
dietary ingredient and dietary supplement initiatives, contribute 
further to the protection of public health.
    b. CGMPs benefit consumers. In addition to the public health 
benefits for consumers, CGMP regulations for dietary ingredients and 
dietary supplements will benefit consumers in other ways. Consumers 
should not have to wonder whether the dietary supplements they buy are 
adulterated or whether they contain the correct dietary ingredients or 
contain the dietary ingredients in the amount stated on the product's 
label. Consumers who purchase a product that does not contain the 
amount or strength listed on the label experience an economic loss 
because they are paying for something that they did not receive. CGMPs 
would require manufacturers to establish and meet specifications for 
identity, purity, quality, strength and composition of dietary 
supplements to help ensure that consumers buy dietary supplements that 
are not adulterated, contain the dietary ingredients declared on the 
product's label, and contain the amount or strength listed on the 
label. Therefore, CGMPs would benefit consumers.
2. How Will CGMP Regulations Take Into Account Technical Feasibility?
    In developing this proposed rule, we were careful not to propose 
requirements that are not technically feasible to meet. In some areas 
where there has been scientific study but where the science is still 
evolving, the proposal recognizes the evolving state of the science, 
but would give you maximum flexibility in meeting the requirement. For 
example, there are tests available for identity, purity, quality, 
strength, and composition of certain dietary ingredients or dietary 
supplements. Because many tests for identity, purity, quality, 
strength, and composition of dietary ingredient or dietary supplements 
have not been officially validated, the proposal would permit tests 
using methods other than those that are officially validated. By using 
the term ``officially validated,'' we mean that the method is validated 
using an interlaboratory collaborative study by which a proposed method 
is validated by independent testing in separate laboratories under 
identical conditions (Ref. 35). An AOAC International (formerly the 
Association of Official Analytical Chemists) Official Method is an 
example of an officially validated method. We discuss test methods 
validation in more detail later in this document.
    In areas where scientific study is still evolving, we did not 
propose specific requirements. For example, we did not propose 
requirements for dissolution, disintegration, bioavailability, or 
expiration dating. In those areas, it may be premature to propose a 
requirement at this time. In the preamble to this rule, we identify 
those areas where additional scientific study is necessary before we 
can propose a dietary supplement CGMP requirement. For example, we did 
not identify defect action levels (DALs) for dietary ingredients 
because there are not enough data available to identify an appropriate 
DAL for most dietary ingredients. Likewise, further study is needed for 
some dietary ingredients before dissolution, disintegration, 
bioavailability, expiration dating, or other quality standard 
requirements can be proposed.
3. How Can FDA Help Industry Achieve Compliance With CGMPs?
    During small business outreach public meetings and in comments to 
the ANPRM, members of the dietary supplement industry told us that they 
would like our help in determining how to implement CGMP regulations 
for dietary ingredients and supplements. We have heard that issuing 
guidance documents and education and training would be helpful. We 
invite comment on the use of guidance documents, education, training, 
or other approaches and potential sources of education and training 
that you believe would assist industry efforts to implement the 
proposed CGMP regulations, if finalized as proposed.

[[Page 12164]]

F. Proposal Highlights and Requests for Comments

    This proposed rule is intended to ensure that manufacturing 
practices will not result in an adulterated dietary supplement and that 
supplements are properly labeled. This proposed rule, if finalized as 
proposed, will give consumers greater confidence that the dietary 
supplements they choose to use will have the identity, strength, 
purity, quality, or composition claimed on the label. A manufacturer of 
a dietary ingredient or a dietary supplement cannot make claims that 
state or imply that the dietary ingredient or dietary supplement is 
safe and/or effective simply because it has been manufactured in 
compliance with current good manufacturing practice (CGMP) 
requirements. However, we believe that a voluntary labeling statement 
about the fact that a dietary ingredient or dietary supplement has been 
made in compliance with CGMP requirements might be made lawfully under 
the act, provided that such a statement is made in an appropriate 
context and with adequate disclaimers so that consumers fully 
understand it and are not misled by it. The proposed rule governing 
CGMP requirements for dietary supplements address manufacturing 
controls to ensure that dietary ingredients and dietary supplements are 
produced in a manner that will not adulterate or misbrand such 
products. Compliance with any final rule, based on the proposal, will 
not ensure that the dietary ingredient or dietary supplement itself is 
safe or effective. Thus, the agency believes that an unqualified 
statement saying simply ``produced in compliance with dietary 
supplement current good manufacturing practice requirements,'' without 
more, could well suggest that a product may be safe and effective or 
somehow superior to other dietary ingredient and dietary supplement 
products that are subject to the same CGMP requirements. Such a 
statement would likely be considered misleading by FDA under sections 
403(a)(1) and 201(n) of the act. We believe however, that it might be 
possible to cure an unqualified statement by including language 
clarifying to consumers that all dietary ingredients and dietary 
supplements must be manufactured in compliance with CGMP requirements 
and that such compliance does not mean that the dietary ingredient or 
dietary supplement is safe or effective. As usual, the manufacturer 
would be responsible for ensuring that any such voluntary labeling 
statements on its dietary ingredient and dietary supplement products 
are truthful and not misleading. The agency would review the lawfulness 
of such statements under sections 403(a)(1) and 201(n) of the act.
    We propose requirements for: (1) Personnel, (2) the physical plant 
environment, (3) equipment and utensils, (4) production and process 
controls, (5) holding and distributing, (6) consumer complaints related 
to CGMPs, and (7) records and recordkeeping. Key provisions of the 
proposed rule are highlighted below. We also seek comment on whether 
certain additional provisions should be included as requirements in a 
final rule.
    Proposed ``personnel'' requirements would require that you have 
qualified employees and supervisors, to take measures to exclude any 
person from your operations who might be a source of microbial 
contamination, and to use hygienic practices to the extent necessary to 
protect against contamination.
    Proposed ``physical plant'' requirements are intended to help 
prevent contamination from your physical plant environment. You would 
be required to design and construct your physical plant in a manner to 
protect dietary ingredients and dietary supplements from becoming 
adulterated during manufacturing, packaging, and holding. You would be 
required to keep your physical plant in a clean and sanitary condition 
and in sufficient repair to prevent contamination of components, 
dietary ingredients, dietary supplements, or contact surfaces.
    Proposed ``equipment and utensils'' provisions would require that 
you use equipment and utensils that are of appropriate design, 
construction, and workmanship for their intended use and that you 
provide for adequate cleaning and maintenance. You would be required to 
maintain and calibrate your instruments and controls for accuracy and 
precision and to ensure that automatic, mechanical, and electronic 
equipment works as intended. You would also be required to maintain, 
clean, and sanitize, as necessary, all equipment utensils and contact 
surfaces that are used to manufacture, package, or hold dietary 
ingredients or dietary supplements.
    Under the proposed ``production and process controls'' 
requirements, you would be required to establish and use a quality 
control unit in your manufacturing, packaging, and label operations. We 
propose requirements for establishing and using master manufacturing 
records and batch control records to ensure batch-to-batch consistency. 
Specifications would be required for any point, step, or stage in the 
manufacturing process where control is necessary to ensure that the 
dietary supplement contains the identity, purity, quality, strength, 
and composition claimed on the label. We propose flexible testing 
requirements: You would be required to test final products for 
adherence to specifications, unless a scientifically valid analytical 
method does not exist; in the latter case, you would be required to 
test incoming shipment lots of components, dietary ingredients, or 
dietary supplements for any such specification, and to test in-process 
for any such specification in accordance with the master manufacturing 
record where you determine control is necessary to ensure the identity, 
purity, quality, strength, and composition of the product.
    Proposed ``holding and distributing'' requirements would protect 
components, dietary ingredients, dietary supplements, packaging, and 
labels against contamination and deterioration. You would be required 
to hold components, dietary ingredients, dietary supplements, 
packaging, and labels under appropriate conditions of temperature, 
humidity, and light so that their quality is not affected; and under 
conditions that do not lead to the mixup, contamination, or 
deterioration.
    Proposed ``consumer complaints'' requirements would require that 
you keep a written record of each consumer complaint related to good 
manufacturing practices; review such complaints to determine whether 
the consumer complaint involves a possible failure of a dietary 
ingredient or dietary supplement to meet any of its specifications, or 
any other requirements of this part, including those that may result in 
a possible risk of illness or injury (i.e., an adverse event); and 
investigate a consumer complaint when there is a reasonable possibility 
of a relationship between the consumption of a dietary supplement and 
an adverse event. For the purposes of this regulation, a consumer 
complaint about product quality may or may not include concerns about a 
possible hazard to health. However, a consumer complaint does not 
include an adverse event, illness, or injury related to the safety of a 
particular dietary ingredient independent of whether the product is 
produced under good manufacturing practices.
    Proposed ``records and recordkeeping'' requirements would tell you 
how long you must keep certain records to show how you complied with 
the CGMP requirements. We would require that you keep written records 
for 3 years beyond the date of manufacture of the last batch of dietary 
ingredients

[[Page 12165]]

or dietary supplements associated with those records and have all 
required records, or copies of such records, readily available during 
the retention period for authorized inspection and copying by FDA when 
requested.
    CGMP records document the manufacturer's operation throughout time 
and are essential to an enforceable regulation. Because FDA does not 
observe the manufacturer's operation fulltime, records can ensure that 
the FDA has the information needed to identify noncompliance and to 
bring a non-compliant manufacturer into compliance. Records can show 
that appropriate monitoring is performed, pinpoint with confidence when 
a deviation began and ended, and prove that required quality control 
measures and practices were performed as often as necessary to ensure 
control. Review of manufacturing records with sufficient frequency can 
ensure that any problems are uncovered promptly and can facilitate 
prompt modification, have an impact on the production of subsequent 
batches of the product, and prevent introduction of potentially 
hazardous dietary supplements into the market place. Review of consumer 
complaint records can facilitate the identification of trends in 
reports of illness or injury, identify related batch records to 
identify previously undetected manufacturing deviation, and have an 
impact on the prompt recall of any potentially hazardous dietary 
supplement.
    We seek comment on whether the proposed recordkeeping requirements 
are not necessary to prevent adulteration; to ensure the identity, 
purity, quality, strength, and composition of the dietary ingredient or 
dietary supplement; to an enforceable regulation; and for the other 
reasons cited. If comments assert that recordkeeping provisions are not 
necessary, comments should include an explanation of why recordkeeping 
requirements are not necessary including how, in the absence of the 
requirements, one can prevent adulteration, ensure the identity, 
purity, quality, strength, and composition of the dietary ingredient or 
dietary supplement, ensure an enforceable regulation, and the other 
reasons cited. If comments agree that the recordkeeping requirements 
are necessary for reasons other than those we have provided, the 
comments should so state and provide an explanation.
    Although records are not required in 21 CFR Part 110, CGMPs in 
manufacturing, packing, or holding human food, records are required in 
the other commodity-driven food CGMPs (i.e., 21 CFR Part 129, 
Processing and bottling of bottled drinking water; 21 Part CFR 120, 
Hazard Analysis and Critical Control Point (HAACP) Procedures for the 
Safe and Sanitary Processing and Importing of Juice; 21 CFR Part 123, 
Fish and fishery products; 21 CFR Part 106 Infant formula quality 
control procedures; and 21 CFR Part 113, Thermally processed low-acid 
foods packaged in hermetically sealed containers). Further, records are 
included in the CGMPs submitted to FDA by industry, the National 
Nutritional Foods Association Standards, the NSF International draft 
standards (Ref. 83), and the USP draft Manufacturing Practices for 
Dietary Supplements.
    We seek comment on whether certain additional provisions should be 
included as requirements in a final rule. For example, we invite 
comment on whether a final rule should include a requirement for 
certain personnel records; for written procedures in a number of areas; 
for equipment verification; and for expiration dating and related 
testing. Written procedures are included in the dietary supplement CGMP 
outline submitted to FDA by industry, National Nutritional Foods 
Association standards, the NSF International draft standards, and the 
USP draft Manufacturing Practices. In order to limit the burden to 
manufacturers, FDA is not proposing to require written procedures. 
However, FDA is proposing that manufacturers maintain appropriate 
records to ensure the identity, purity, quality, strength, and 
composition of a given product and records that are necessary for 
efficient enforcement and to permit trace back. Although we have not 
proposed requirements for written procedures as did these other groups, 
we seek comment on whether such practices should be included in a final 
rule. Later in this document, we request comments on specific written 
procedures and describe FDA's current thinking concerning what could be 
included in such a written procedure.
    We also seek comment on whether this rule should include specific 
requirements for the use of animal-derived dietary ingredients, and 
requirements for persons who handle raw agricultural commodities. 
Specific requests for comment of this type are contained below in 
relevant sections of this preamble.

II. General Issues

A. Legal Authority

    We are proposing these regulations under sections 201, 393, 409, 
701(a), 704, and 801 of the act (21 U.S.C. 321, 903, 348, 371(a), 374, 
and 381) and sections 402 and 403 of the act and section 361 of the 
Public Health Service Act (the PHS Act) (42 U.S.C. 264).
    Section 402(g) of the act gives us explicit authority to issue a 
rule regulating conditions for manufacturing, packaging, and holding 
dietary supplements. Section 402(g)(1) of the act states that a dietary 
supplement is adulterated if ``it has been prepared, packed, or held 
under conditions that do not meet current good manufacturing practice 
regulations.'' Section 402(g)(2) of the act authorizes us to, by 
regulation, ``prescribe good manufacturing practices for dietary 
supplements.'' In addition, section 402(g)(2) of the act states that 
any such regulations ``shall be modeled after current good 
manufacturing practice regulations for food and may not impose 
standards for which there is no current and generally available 
analytical methodology.''
    In section 402(g)(2) of the act, which describes the general 
parameters of CGMPs for dietary supplements, Congress stated that the 
regulations were to be ``modeled after current good manufacturing 
practice regulations for food.'' To determine what Congress meant, we 
look to the plain meaning of the phrase. Webster's II New Riverside 
University Dictionary defines ``model'' as ``[a] preliminary pattern 
serving as the plan from which an item not yet constructed will be 
produced'' (Ref. 81). Thus, when Congress used the term ``modeled 
after'' Congress intended that we use the food CGMPs as a ``preliminary 
pattern'' for the dietary supplement CGMPs. If Congress had intended 
for the agency to adopt food CGMPs as the CGMPs for dietary 
supplements, Congress could have explicitly stated that dietary 
supplements were subject to food CGMPs.
    The provisions in the dietary supplement CGMP proposal are modeled 
after food CGMPs. The general CGMP provisions for food in part 110 
relate not only to insanitary production practices, but other 
practices, such as having appropriate quality control operations, to 
ensure that a food is manufactured in a manner that will not adulterate 
the food. Further, the CGMPs in part 110 describe the minimally 
acceptable practices for all food handling operations. They are not 
intended to cover specific issues that may relate to a particular 
product type, rather, are general provisions concerned with practices 
relating to the receiving, inspecting, quality control operations, 
packaging, segregating, processing, storing, and transporting of food. 
The specific provisions of the food CGMPs

[[Page 12166]]

are linked to hazards that are inherent to foods (e.g., microbial 
contamination and contamination with macroscopic filth).
    The proposed dietary supplement CGMPs are modeled after the food 
CGMPs in part 110 in that they cover the scope of practices related to 
the receiving, inspecting, quality control operations, packaging, 
segregating, processing, storing, and distribution of dietary 
ingredients and dietary supplements. Dietary supplements require many 
of the same types of sanitary practices and other practices as 
conventional food production in order to produce a product that is not 
adulterated; dietary supplements are subject to many of the same 
hazards as are conventional foods. However, dietary supplements have 
their own set of unique requirements as a result of the characteristics 
and hazards due to their ``hybrid'' nature, e.g., dietary supplements 
can be considered as falling somewhere along the continuum between 
conventional foods on the one hand and drugs on the other. Thus, the 
CGMPs for dietary supplements need to address the characteristics and 
hazards of dietary supplements, the operations and processes used to 
manufacture dietary supplements, particularly those necessary to ensure 
the identity, purity, quality, strength, and composition claimed on the 
label.
    Dietary supplements, unlike conventional foods, contain ingredients 
that are consumed in very small quantities, for example, in a tablet or 
capsule. Such ingredients may be intended to have an anticipated, 
specific physiological response. Such ingredients are more ``drug-
like'' than ``food-like,'' in part, because very small changes in the 
strength, purity, or quality of the ingredient can have significant, 
and possibly adverse, health consequences to those who ingest it. Thus, 
the dietary supplement CGMPs, by necessity, need to include provisions 
related to identity, purity, strength, quality, and composition of the 
product so that the dietary supplement ``food'' product will be 
manufactured in a manner that will not result in adulteration.
    Further, plant products that are used to produce dietary 
supplements may be ground or in a powder and not easily recognized 
compared to conventional food that is readily identifiable (e.g., one 
can readily distinguish between white flour and white sugar, but not 
between ground plaintain and ground D. lanata). Thus, for the 
manufacturer to be sure that the dietary supplement contains the 
correct ingredient and the amount of the ingredient that is intended, 
the manufacturer must test or examine the ingredient using appropriate 
methods. The ``modeled after'' language in section 402(g) of the act 
provides the agency with the flexibility to devise CGMPs that make 
sense for dietary supplements, and that are based on the same 
principles as food CGMPs in part 110, i.e., to prevent adulteration 
related to insanitary conditions or other conditions that may be 
necessary to prevent adulteration, given the nature of the specific 
food product and the characteristics of, and hazards inherent in, that 
food.
    The scope of the legal authority for the proposed dietary 
supplement CGMPs includes the legal authorities upon which the food 
CGMPs are based. For example, section 402(a)(3) of the act states that 
a food is deemed adulterated if ``it consists in whole or in part of 
any filthy, putrid, or decomposed substance, or if it is otherwise 
unfit for food.'' Section 402(a)(4) of the act states that a food is 
deemed adulterated if ``it has been prepared, packed, or held under 
insanitary conditions whereby it may have become contaminated with 
filth, or whereby it may have been rendered injurious to health.'' 
While section 402(a)(3) of the act focuses on the food itself, section 
402(a)(4) of the act focuses on the conditions under which the food is 
prepared, packed, or held. Courts have adopted a broad reading of 
section 402(a)(4) of the act when we have taken actions to advance the 
public health (see U.S. v. Nova Scotia Food Products Corp., 568 F. 2d 
240, 248 (2d Cir. 1977)). The agency tentatively concludes that the 
authorities that it relied on for its umbrella CGMPs in part 110 for 
food are relevant to the authorities that it needs for this proposed 
rule for dietary supplement CGMPs. In addition, section 409 of the act 
is another provision that is relevant to dietary supplement CGMPs. 
Section 409 of the act addresses circumstances under which a food may 
be deemed adulterated based on the use of a food additive. Section 409 
of the act is relevant to good manufacturing practices for foods, 
including dietary supplements, because a food would be deemed 
adulterated if it contained a food additive that was not used in a 
manner consistent with the statutory and regulatory requirements under 
section 409 of the act (see sections 402(a)(2)(C) and 409 of the act). 
Although Congress explicitly excluded ``dietary ingredients,'' as 
defined in section 201(ff) of the act, from the definition of food 
additive, (see section 201(s)(6) of the act), ingredients other than 
dietary ingredients in a dietary supplement are subject to regulation 
as a food additive under section 409 of the act, unless they are 
subject to an exception to the definition of ``food additive'' under 
section 201(s) of the act.
    Moreover, dietary ingredients and dietary supplements may contain 
pathogenic bacteria or viruses that pose serious public health and 
safety concerns (Ref. 36). Botanical dietary ingredients are living 
plants that may contain different microorganisms. These include 
Lactobacillus, Leuconostoc, Pseudomonas, and Xanthomonas species and 
molds. Potential pathogens such as Listeria monocytogens, Pseudomonas 
aeruginosa and Enterobacteriacae may also be present. Secondary 
microbial contamination from soil (Bacillus cereus, Clostridium 
perfringens and mycotoxin-producing molds, etc.), animal feces 
(Salmonella and Shigella spp., Escherichia coli) and handling 
(Staphylococcus aureus) can also occur during harvesting, processing, 
and transportation (Ref. 36). Animal-derived dietary ingredients or 
dietary supplements may also pose a risk. For example, bovine 
colostrum, the lacteal secretion which precedes milk after a cow gives 
birth, is a substance that is used in dietary supplements and likely 
presents the same potential health risks as does milk. Bovine milk may 
contain pathogenic organisms capable of causing diseases in man such as 
tuberculosis or undulant fever. Glands and other animal tissues may 
contain the infective agent that causes transmissible spongiform 
encephalopathy (TSE) if they originate from an animal infected with the 
disease (Ref. 37).
    We have authority to issue regulations under section 361 of the PHS 
Act. The Secretary delegated authority to the Commissioner of FDA (the 
Commissioner) to exercise the functions vested in the Secretary under 
section 361 of the PHS Act (see 21 CFR 5.10(a)(3)). This authority 
authorizes the Commissioner to issue and enforce regulations that, in 
the Commissioner's judgment, are necessary to prevent the introduction, 
transmission, or spread of communicable diseases from one State to 
another. Because this authority is designed to eliminate the 
introduction of diseases from one State to another, the Commissioner 
may exercise the authority over the disease-causing substance within 
the State where the food is manufactured, packaged, or held. The 
Commissioner, therefore, assumes the authority to issue regulations 
under the PHS Act to assure that foods are manufactured, packaged, and 
held under conditions that will prevent the introduction, transmission,

[[Page 12167]]

or spread of communicable diseases between States. Thus, the agency is 
invoking its authority under the PHS Act in this proposed rule to 
prevent the spread of communicable disease from dietary ingredients or 
dietary supplements in intrastate and interstate commerce.
    In developing proposed CGMPs for dietary supplements, we relied on 
the basic concept underlying the food CGMPs and upheld by the courts. 
As a result, the basic concept for the food CGMPs and the proposed 
dietary supplement CGMPs is the same: To establish regulations that 
will help ensure that your practices for preparing, packaging, and 
holding dietary ingredients and dietary supplements do not result in an 
adulterated food entering interstate commerce.
    In addition to relying on the broad authority in relevant sections 
of the act that we used to issue the food CGMP regulations, we look to 
the other relevant statutory language in section 402(g) of the act and 
the act as a whole in deciding the basis for our legal authority in 
proposing regulations related to the manufacture, packaging, and 
holding of dietary ingredients and dietary supplements. We note that 
certain terms Congress used in section 402(g)(2) of the act, i.e., 
``standards'' and ``current and generally available analytical 
methodology,'' show that Congress intended to give us the authority to 
establish regulations in this rule that do not have parallel provisions 
in other food CGMPs. Specifically, the second phrase of the second 
sentence in section 402(g)(2) of the act states that we ``may not 
impose standards for which there is no current and generally available 
analytical methodology.'' ``Standards'' and ``current and generally 
available analytical methodology'' are terms of art in the scientific 
field, and we are relying on the meaning of these terms in the field of 
science in these proposed CGMPs regulations, which implement that 
provision. This statutory language does not limit CGMPs for dietary 
supplements solely to the food CGMP regulations at the time DSHEA was 
enacted. If Congress had intended for the CGMPs for dietary supplements 
to be identical to the CGMPs for food, the language in section 
402(g)(2) of the act relating to ``standards'' and ``current and 
generally available analytical methodolog[ies]'' would be meaningless. 
Thus, CGMP regulations for dietary ingredients and dietary supplements 
may include provisions relevant to dietary ingredients and dietary 
supplements that were not in current food regulations at the time DSHEA 
was enacted.
    In addition to the broad authority in section 402(g) of the act, we 
look to the statutory scheme of DSHEA as a whole in proposing 
regulations related to the manufacture, packaging and holding of 
dietary ingredients and dietary supplements. Section 403(q)(5)(F) of 
the act (section 7(b) of DSHEA) requires that a dietary supplement 
product provide nutrition information. To comply with section 
403(q)(5)(F) of the act, you must be able to identify the dietary 
ingredient or ingredients in a dietary supplement and the quantity of 
each. Moreover, the provisions in section 403(s) of the act relate to 
identity, purity, quality, strength, and compositional specifications 
of a dietary supplement. Thus, Congress sought to ensure in DSHEA that 
dietary supplements would provide accurate information to the consumer 
on the identity of the dietary ingredient and, if an herb or botanical, 
the source from which it is derived. Moreover, Congress sought to 
ensure that the dietary supplement would have the strength or meet the 
quality, purity, and compositional specifications that the dietary 
supplement is represented to meet. Because Congress established section 
403(s) of the act--a provision that requires that a dietary supplement 
that bears representations about identity, purity, quality, strength, 
and compositional specifications meet those representations--it is 
reasonable for us to establish regulations for manufacturing, 
packaging, and holding addressing those same features. These 
representations relate to characteristics and hazards to which dietary 
supplements are subject. Further, in section 402(f) of the act, 
Congress identified circumstances under which a dietary supplement or a 
dietary ingredient would be deemed adulterated because it may present a 
significant or unreasonable risk of illness or injury. Congress 
expected that a dietary supplement would be manufactured in a way that 
ensures that the dietary supplement contains dietary ingredients that 
do not present an unreasonable risk of illness or injury and for which 
the conditions of use are based. Because one must be able to measure or 
analyze a dietary ingredient in order to determine whether a supplement 
in fact contains that dietary ingredient, it is reasonable for a 
proposed rule on CGMPs to include provisions related to identity, 
purity, quality, strength, and composition of a dietary ingredient or a 
dietary supplement. Moreover, it is reasonable to propose a requirement 
that records of complaints be kept and investigations be done, as 
necessary, so that the manufacturer and FDA can be aware of any 
potential problems relating to a particular dietary ingredient and 
these CGMPs, and so that a manufacturer can take appropriate action 
when necessary. The proposed CGMPs would reflect the act's regulatory 
scheme generally and, more specifically, DSHEA's provisions that 
contemplate consistent, controlled manufacture of dietary supplements 
(see sections 402(f) and 403(q)(5)(F) and (s) of the act). We 
tentatively conclude that, therefore, section 402(g)(2) of the act 
gives us the authority to develop dietary supplement CGMPs that are not 
identical to our food CGMPs and that are appropriately tailored to the 
manufacturing, packaging, and holding of dietary ingredients and 
dietary supplements.
    Sections 701(a) and 704 of the act also give us authority to 
establish regulations related to CGMPs for dietary ingredients and 
dietary supplements. Under section 701(a) of the act, we have the 
authority to issue regulations for the efficient enforcement of the 
act, and such regulations have been held to have the force and effect 
of law (see National Nutritional Foods Ass'n v. Weinberger, 512 F.2d 
688, 697-98 (2d Cir. 1975)). Section 704 of the act gives us the 
authority to inspect factories, warehouses, and other establishments in 
which foods, including dietary ingredients and dietary supplements, are 
manufactured, processed, packed, or held and to inspect their 
facilities, equipment, finished and unfinished materials, containers, 
and labeling.
    In addition to having the authority to establish broad regulations 
for manufacturing, packaging, and holding dietary ingredients and 
dietary supplements, we also have the authority to require 
recordkeeping as part of these regulations. Two questions that we 
considered in deciding whether to propose requirements for 
recordkeeping included whether the statutory scheme as a whole 
justified the proposed regulation and whether the proposed 
recordkeeping requirements would be limited, would clearly assist in 
the efficient enforcement of the act, and would not create an 
unreasonable recordkeeping burden. In the other relevant sections of 
this document, we explain in more detail the recordkeeping provisions 
that we believe are limited to what are necessary for the efficient 
enforcement of the act, and because the requests are limited, would 
therefore not create an unreasonable recordkeeping burden.
    For this proposed CGMP rule for dietary ingredients and dietary 
supplements, recordkeeping is necessary to provide the type of

[[Page 12168]]

documentation that would demonstrate that dietary ingredients and 
dietary supplements are manufactured, packaged, and held under the 
conditions that would be required under the proposed CGMP regulations. 
Further, FDA is using its authority under sections 801 and 701(a) of 
the act in proposing recordkeeping requirements for dietary ingredients 
and dietary supplements that may not be marketed or sold in the United 
States and that are exported under section 801(e) of the act.
    In addition to having the authority under the act to require 
recordkeeping, we also have authority to require access to the records. 
Because the practices set forth in the proposed CGMP rule are necessary 
to providing consumers with dietary supplements that are not 
adulterated, access to records that demonstrate that firms follow CGMPs 
is essential to confirming systematic compliance with CGMPs. We also 
have the authority to copy the records when necessary. We may consider 
it necessary to copy records when, for example, our investigator may 
need assistance in reviewing a certain record from relevant experts in 
headquarters. If we were unable to copy the records, we would have to 
rely solely on our inspector's notes and reports when drawing 
conclusions. A failure to have a required record would mean that a food 
is adulterated under section 402(g) of the act.
    Recordkeeping will not only help the agency to determine whether 
dietary ingredients or dietary supplements were manufactured, packaged, 
and held consistent with CGMP regulations, but also will provide a 
public health benefit to consumers. When manufacturers keep records, 
for example, of lot or batch numbers, the records facilitate a 
manufacturer's recall of suspect products in case a recall becomes 
necessary. This benefits consumers because the manufacturer can recall 
its products that may be adulterated or misbranded more quickly.

B. Issues From the ANPRM

    As stated previously, in addition to inviting comment on the 
industry-drafted CGMP outline, we asked nine questions in the ANPRM on 
CGMP issues for dietary supplements that the industry outline did not 
address. In this section, we summarize each question and the principal 
comments we received, and we respond to the comments. We address other 
significant comments about the ANPRM, other than the nine questions we 
asked, elsewhere in this document.
    The nine questions in the ANPRM, comments, and our responses are as 
follows:
    Question 1. Is there a need to develop specific defect action 
levels (DALs) for dietary ingredients?
    The ANPRM stated that the use of a botanical in a dietary 
supplement may result in a much greater exposure to the botanical 
ingredient for consumers because the dietary supplement will be 
consumed in greater amounts than if the ingredient was in a food as a 
spice or flavoring agent.
    Several comments stated that establishing DALs for dietary 
ingredients that are different than DALs for food is not necessary. The 
comments disagreed with our statement that dietary ingredients in 
dietary supplements and conventional foods are consumed in different 
quantities. For example, the comments stated that generally botanical 
ingredients are present in dietary supplements in approximately the 
same amounts normally consumed in conventional foods.
    Other comments generally opposed applying the current DALs for 
foods to dietary ingredients and instead supported the development of 
DALs for dietary ingredients, especially for botanicals and herbals. 
Many comments recommended that we cooperate with industry, outside the 
rulemaking process, to develop DALs for dietary ingredients.
    We disagree with the comments that state that establishing DALs for 
dietary ingredients that are different than DALs for food is not 
necessary because an ingredient in food and in a dietary supplement 
would be consumed in the same amounts. The comment did not provide 
evidence or examples to support the comment. Some food ingredients for 
which DALs have been established also are dietary ingredients used in 
dietary supplements. For example, a DAL has been established for whole 
ginger used in a conventional food. Ginger is also a dietary ingredient 
used in dietary supplements. We have found dietary supplements that 
recommend a daily intake of ginger of 4,815 mg, 1,260 mg, and 2,200 mg 
(Ref. 38). One teaspoon of raw ginger root is equal to 2,000 mg (2 
grams (g)) and one teaspoon of ground ginger is equal to 1,800 mg of 
ginger (1.8 g) (Ref. 39). A recipe for gingersnaps yielding 18 cookies 
specifies 1 teaspoon ginger (Ref. 40). Thus, ginger would be consumed 
in greater amounts as a dietary supplement than as an ingredient in a 
conventional food. However, we have tentatively concluded that we do 
not have sufficient information to determine whether a DAL for a 
dietary ingredient should be established at a different level than what 
has been established for the same ingredient used in conventional food.
    DALs are established for a food ingredient on a per weight basis. 
The DALs for whole ginger for ``insect filth and/or mold'' is an 
``average of 3 percent or more pieces by weight are insect-infected 
and/or moldy'' and for ``mammalian excreta'' is an ``average of 3 mg or 
more of mammalian excreta per pound'' (Ref. 41). Because the DAL is 
established by weight of the whole ginger, the DAL for ginger would 
apply whether it is used as an ingredient in a conventional food or a 
dietary ingredient in a dietary supplement. Therefore, if we have 
established a DAL in the industry compliance document for a 
conventional food ingredient, that DAL also would apply to that 
ingredient when used as a dietary ingredient in a dietary supplement 
until such time that we would establish a different DAL for its use as 
a dietary ingredient (Ref. 41). However, we do not have many dietary 
ingredients that are included in the DAL compliance guide. We agree 
that DALs may be needed for some dietary ingredients, especially 
ingredients like botanicals that are subject to the same type of 
defects (such as mold and insect parts) as other food for which DALs 
have been established. We base DALs on scientific information such as 
literature surveys, scientific market surveys, and laboratory analyses 
and also on information gained through physical plant inspections. If 
and when we determine that we have sufficient information to develop 
DALs for dietary ingredients, we will consider whether to do so.
    Question 2. We requested comments on appropriate testing 
requirements to provide positive identification of dietary ingredients, 
particularly plant materials, used in dietary supplements.
    The ANPRM explained that the misidentification of dietary 
ingredients, particularly plant materials, used in dietary supplements 
may present a significant public health and economic concern. The ANPRM 
also noted that the analytical methodology available for identifying 
many dietary ingredients is limited. We invited comments on the 
technical and scientific feasibility of identifying different types of 
dietary ingredients. We also solicited information on what constitutes 
``adequate testing'' for identity of different types of dietary 
ingredients, and, in the absence of testing, what types of practices 
would be effective alternatives to testing to ensure the

[[Page 12169]]

identity of different types of dietary ingredients.
    Comments generally supported requiring tests of some kind to 
positively identify dietary ingredients and to verify dietary 
ingredient identity. The comments put forth different reasons, which 
ranged from ensuring public safety to preventing economic adulteration. 
Some comments suggested that suppliers should be responsible for 
identifying the dietary ingredients they supply to manufacturers and 
that manufacturers should be responsible for only verifying the 
identity of the finished product. Other comments stated that the 
manufacturer should be responsible for identification and should not 
rely on a supplier's certification.
    Some comments raised issues relating to the actual identity tests 
that should be recommended or required and discussed analytical method 
selection and method options, use of and availability of official 
validated analytical methods, and certification of testing facilities 
that conduct identity tests on natural products. Some comments 
suggested that identity test method options should include organoleptic 
and microscopic methods and chemical analytical methods. The comments 
noted that selecting the appropriate method is dependent on the type 
and form of the ingredient. Other comments said that manufacturers 
should be responsible for selecting the appropriate method to confirm 
ingredient identity. Most comments recommended that we provide guidance 
to industry in defining what comprises adequate testing for different 
types of ingredients, but did not support regulations prescribing the 
test method or methods for specific ingredients.
    Comments generally supported the use of a standard compendial 
method, such as those published by the USP or AOAC International. Where 
no published method exists, the comments suggested that manufacturers 
should be responsible for developing adequate and effective 
identification testing procedures, requirements, or practices to ensure 
the identity of the dietary ingredients they use. One comment from a 
vitamin manufacturer noted that most of its products have recognized 
and established identity tests as part of their compendial status. 
Other comments from botanical dietary supplement manufacturers noted 
that their current methods for identifying plant material are adequate, 
but that they will, over time, be enhanced by the availability of more 
widely recognized methods and techniques as a result of current work in 
this field. The comments noted that test methods that are presently 
available and used for identifying botanicals are not officially 
validated. If an officially validated method is not available for a 
dietary ingredient, several comments suggested working towards AOAC 
International validation and, in the interim, instituting peer review 
of less formal test methods. Other comments noted that the dietary 
supplement industry has begun an effort to develop validated test 
methods for several botanical ingredients. One comment suggested that 
it is important to develop methods that are subject to peer review and 
to institute a certification program for testing facilities because the 
analysis of natural products requires specialized training in natural 
product chemistry. The comment did not indicate who (e.g., FDA or 
another organization) should develop a certification program.
    Some comments only addressed identity testing of unprocessed 
botanicals. These comments said that for unprocessed botanicals in 
whole or in part (e.g., flowers, roots, leaves, etc.), organoleptic 
techniques are sufficient provided that accurate records are maintained 
and that the manufacturing process provides a paper trail of positive 
identification. One comment suggested that a ``voucher specimen'' (a 
sample of the plant material) from the supplier along with a 
certificate of botanical identity would be an adequate record. The 
certificate of botanical identity would follow the material through the 
manufacturing process, thus creating a paper trail. The voucher 
specimen would be held for a specific period of time or, if necessary, 
serve as a permanent record.
    Dietary ingredient identification is an important part of CGMPs. We 
agree with the comments that identity testing requirements are needed 
but that no single approach or test method may be appropriate for every 
dietary ingredient. For example, microscopic or organoleptic tests 
might be appropriate for herbs or plant parts (because you can see, 
taste, or smell them), but not appropriate for amino acids (which 
cannot be identified by the naked eye or identified by using your 
senses). A microscopic test might be appropriate for herbs that still 
have their leaves or other distinguishing marks or characteristics, but 
not for ground-up herbs. Thus, we agree with the comments stating that 
the key principle in dietary ingredient identification testing is to 
establish an appropriate procedure that will identify, with certainty, 
the dietary ingredients used in making a dietary supplement. We agree 
that a guidance document on ingredient identity testing may be useful, 
and we will consider future development of ingredient identity testing 
guidance documents.
    Manufacturers should be responsible for identifying the ingredients 
that they use in their products and, in addition, for verifying that 
the dietary ingredients or dietary supplements they make contain the 
identity, purity, quality, strength, and composition that the 
manufacturer intends the product to have. As discussed previously in 
this document, we have found serious adverse events to be related to 
dietary ingredient misidentification. The manufacturer must conduct 
identity tests to ensure that they used the correct ingredient to 
prevent potential serious adverse events. We discuss identity testing 
for dietary ingredients and dietary supplements later in this document.
    We agree with the comments that certification of testing facilities 
could be an important step in ensuring analytical quality. However, 
certification of testing facilities is outside the scope of this rule.
    Question 3. FDA requested comments on standards that should be met 
in certifying that a dietary ingredient or dietary supplement is not 
contaminated with filth; that it is free of harmful contaminants, 
pesticide residues, or other impurities; that it is microbiologically 
safe; and that it meets specified quality and identity standards.
    The ANPRM noted that, under Sec.  110.80, a food manufacturer may 
accept a supplier's certification that its products do not contain 
microorganisms, filth, or other foreign material that would adulterate 
the product instead of testing or evaluating the supplier's products 
itself. As a result, we asked for comments on whether a certification 
will provide assurance that dietary ingredients are not contaminated or 
whether specific testing requirements are necessary.
    Comments generally supported relying on a supplier's certification 
that a dietary ingredient is what it purports to be and is not 
contaminated. The comments stated that reliance on the supplier's 
certification should be an alternative to testing raw materials to 
detect microorganisms, filth, or foreign material so long as the 
reliability of the supplier's certification is confirmed. Most comments 
stated that manufacturers are responsible for determining, on a case-
by-case basis, whether a supplier's certification provides adequate 
assurance that a dietary ingredient is what it purports to be and is 
not adulterated. Some comments based their support for

[[Page 12170]]

relying on a supplier's certification on Sec.  110.80(a)(2) through 
(a)(4); these provisions allow food manufacturers to rely on a 
supplier's guarantee or certification that raw materials or other 
ingredients do not contain levels of microorganisms or toxins that may 
produce illness or are otherwise contaminated. The comments suggested 
various means for determining the reliability of a supplier's 
certification, including independent analysis, in-house testing, and 
review of protocols.
    Other comments stated that, because the CGMP regulations in part 
110 permit reliance on a supplier's certification and because section 
402(g)(2) of the act specifies that the CGMP regulations for dietary 
supplements should be modeled after the CGMP regulations for food, a 
supplier's certification for dietary supplements must be acceptable.
    We have considered the comments on whether a supplier's 
certification could provide adequate assurance that a dietary 
ingredient is what it purports to be and is not adulterated. We 
disagree that manufacturers may rely on such certifications to 
determine that an ingredient is not contaminated, for example, with 
filth or microorganisms. Using a supplier certification, guarantee, or 
certification in lieu of performing testing on each shipment lot of 
components, dietary ingredients, or dietary supplements is not 
appropriate because a supplier's certification or guarantee would not 
necessarily ensure that the identity, purity, quality, strength, or 
composition of a component, dietary ingredient or dietary supplement is 
met. We discuss testing requirements and why we believe that the use of 
supplier's guarantee or certification is not sufficient in lieu of a 
manufacturer's own testing in more detail later in this document.
    Question 4. We asked for comments on whether a CGMP rule should 
require manufacturers to establish procedures to document, on a 
continuing or daily basis, that they followed preestablished procedures 
for making dietary supplements.
    The ANPRM noted that the food CGMP regulations under part 110 do 
not require manufacturers to document that they are following 
established procedures prescribed for manufacturing a food. However, 
the ANPRM also noted that section 402(g) of the act does not preclude 
us from adopting CGMP requirements for dietary ingredients and dietary 
supplements that have no counterpart in part 110 if we have an 
appropriate basis for doing so.
    Most comments generally supported requiring manufacturers to 
develop and follow written procedures and noted that the industry 
outline in the ANPRM would require written procedures for many 
processes and functions. Some comments noted that written procedures 
and day-to-day records documenting that the procedures were followed 
will ensure that products are safely and properly manufactured on a 
day-to-day basis and that this can be confirmed by periodic independent 
internal audits. One comment stated that the manufacturer should be 
responsible for ensuring, through employee training, self-audit 
programs, and batch records, that quality control and other procedures 
prescribed for the manufacture of a dietary supplement are properly and 
diligently executed. Other comments stated that it is good business 
practice to ensure product quality through periodic review of records 
and quality control audits and that failure to establish procedures 
will result in product recalls, potential injury, and litigation for 
damages for defective goods.
    Some comments objected to any requirement for written procedures or 
documentation that the procedures were followed. The comments stated 
that section 402(g)(2) of the act states that dietary supplement CGMPs 
must be modeled after the food CGMP regulations and the food CGMP 
regulations do not require written procedures or documentation that 
procedures were followed.
    We agree with those comments that support the development and use 
of written procedures by manufacturers and are considering whether we 
should require written procedures in a final rule. We are proposing 
requirements for documenting certain operations and processes while not 
requiring written procedures to remove underlying costs for 
establishing and updating such written procedures while preserving the 
records necessary to permit trace back. When manufacturers develop and 
follow written procedures such procedures help to ensure that 
manufacturers produce a consistent dietary ingredient or dietary 
supplement that is of a predictable quality and that is not 
adulterated. Following written procedures and documenting compliance 
with those procedures will ensure regular performance of a firm's 
established programs and procedures and will provide additional 
assurance of effective communication of appropriate information from 
the firm management to the line personnel. We invite comment on whether 
written procedures should be required in a final rule, and whether 
there are other procedures, that we should include in a final rule. We 
discuss written procedures for various stages of manufacturing, 
packaging, labeling, holding, and for handling consumer complaints 
later in this document.
    We disagree, however, that records are not necessary to show that 
certain operations and processes are being performed. Records document 
that quality control operations and processes such as calibrating 
instruments and controls; manufacturing a dietary ingredient or dietary 
supplement batch; and handling consumer complaints were performed. We 
further discuss the basis for the proposed recordkeeping requirement 
for certain operations and processes later in this document. We believe 
that section 402(g) of the act allows us to require written procedures 
and documentation that the procedures were followed. As explained 
previously, such records may be necessary for ensuring that dietary 
ingredients and dietary supplements are manufactured, packaged, and 
held consistent with these regulations. Moreover, we believe that the 
fact that the food CGMPs in part 110 do not have recordkeeping 
requirements does not preclude us from proposing recordkeeping 
requirements in this proposed rule, although we seek further comment on 
the issue.
    Question 5. We invited comment on whether dietary supplement CGMP 
regulations should require that firms have competent medical 
authorities evaluate reports of injuries or illnesses and to determine 
if followup action is necessary to protect the public health.
    The ANPRM explained that many dietary supplements contain 
pharmacologically active substances, which distinguish dietary 
supplements from many foods, and some dietary supplements may contain 
potential allergens. Because the characteristics may result in adverse 
events in certain consumers, we asked whether we should consider 
requiring firms to take certain actions with respect to reviewing AERs. 
We also sought comments on whether a CGMP rule should require firms to 
establish procedures for determining whether a reported injury 
constitutes a serious problem, and what actions are to be taken when 
serious problems are identified.
    Comments generally opposed requiring manufacturers to establish a 
procedure for evaluation and followup of reports of illness and 
injuries. Comments also opposed requiring that a competent medical 
authority evaluate all reports of illness or injuries to determine if 
followup action is necessary to protect the public health. Some 
comments, opposing requiring written procedures and evaluation,

[[Page 12171]]

suggested alternatives to requirements, such as using the Centers for 
Disease Control and Prevention, poison control centers, FDA's MedWatch 
program, and consumer complaint files to monitor and record injuries 
and illnesses attributed to marketed products.
    In contrast, several comments supported a requirement for written 
procedures or medical evaluation of serious adverse events. Some 
comments stated that an evaluation procedure is necessary and that 
manufacturers are and should be responsible for establishing procedures 
to respond appropriately to reports of serious illness and injury that 
may have resulted from using a dietary supplement. Other comments 
stated that medical evaluations are not necessary because manufacturers 
should be using appropriate internal quality control procedures within 
their quality control units or elsewhere to identify the cause of 
adverse events and respond appropriately.
    We agree with those comments stating that manufacturers are and 
should be responsible for evaluating consumer complaints. Manufacturers 
have an obligation to ensure that the dietary supplements that they put 
on the market are not adulterated or misbranded. Consumer complaints 
about a dietary supplement might indicate a CGMP-related problem 
associated with a dietary supplement. For example, a consumer complaint 
might identify a previously unknown manufacturing deviation that caused 
a batch of dietary supplements to be adulterated. Thus, a procedure for 
reviewing and investigating consumer complaints is recommended. Records 
of consumer complaints related to CGMPs, and the review and 
investigation of such records, are necessary and we discuss such a 
record requirement later in this document. In that discussion, we 
address what we mean by a consumer complaint and we address the 
comments on the type of evaluation that would be necessary for consumer 
complaints and whether the comments' suggested alternatives to written 
procedures and medical evaluations are sufficient to identify potential 
concerns.
    Some comments objected to written procedures and medical evaluation 
arguing that such requirements go beyond the CGMP regulations for food 
and, therefore, would be contrary to section 402(g)(2) of the act. 
Other comments claimed that written procedures would present 
unwarranted potential criminal liability, that there are many 
unsubstantiated injuries and illness inherent in the food industry, and 
that dietary supplement safety problems are rare. These comments also 
stated that a costly and burdensome safety surveillance system is not 
warranted for these products, that the term ``serious adverse event'' 
is ambiguous, and that most manufacturers lack trained medical 
personnel to serve this function.
    Because we have found dietary supplement problems that could have 
been prevented by CGMPs and that resulted in product recalls, we find 
that manufacturers must be able to identify these types of problems 
with their products. It is a manufacturer's responsibility to do so. We 
disagree with those comments stating that we do not have legal 
authority to require a manufacturer to evaluate consumer complaints as 
we propose to define that term in this proposed rule.
    We also disagree that written procedures would present unwarranted 
potential criminal liability. Persons subject to regulation under the 
act and its implementing regulations may face civil or criminal action 
if they fail to comply with the act or our regulations (see, e.g., 
sections 301, 302, and 303 (21 U.S.C. 331, 332, and 333) of the act). 
The fact that such an outcome is possible under the statutory scheme 
does not mean that a provision that would require written procedures 
and evaluation of consumer complaints is ``unwarranted.'' If we were to 
accept such a claim, then we would find it difficult to issue any 
regulation to implement the act, and that result would conflict with 
our obligation to protect the public health. Therefore, we reject the 
comments' argument regarding potential criminal liability and its 
effect on rulemaking.
    We also disagree with the claim that there is no basis for 
requiring an evaluation of adverse events because there are many 
unsubstantiated reports of injuries or illness and because dietary 
supplement safety problems are rare. In the past, voluntary reports of 
injury or illness have identified adulterated dietary supplements. 
Consumer complaint reports associated with the use of marketed dietary 
supplements, such as D. lanata contaminated plantain, identified the 
need for further investigation and led to recalls or warnings to 
protect the public health (Ref. 6). Evaluation of consumer complaint 
reports can reveal patterns of adverse events that assist us and 
manufacturers in identifying the need for further investigation to 
determine what public health actions are needed.
    For example, assume that, after you investigate an AER, you find 
that the product contained an ingredient that should not have been used 
and that the ingredient caused the adverse event. The fact that the 
wrong ingredient appeared in your product would indicate that some type 
of problem occurred in your manufacturing process of that product. Once 
you identify the ingredient as the cause of the problem, you would be 
able to take steps to remove any such product from the market and 
prevent the problem from recurring, helping to ensure product quality 
and purity, and restore consumer confidence that your products contain 
the correct ingredients. In short, investigations of consumer 
complaints benefit both manufacturers and consumers and these benefits 
will exist regardless of whether there are many or few injuries or 
illnesses believed to be associated with your product.
    Question 6. We invited comment on whether a CGMP regulation for 
dietary supplements should require manufacturers to establish 
procedures to identify, evaluate, and respond to potential safety 
concerns with dietary ingredients. We asked whether such an evaluation 
is necessary, and, if so, what elements need to be included in such an 
evaluation and their relative importance (e.g., the presence and 
potency of pharmacologically active substances, the presence of 
different microorganisms, the presence of different contaminants and 
impurities). We also asked whether we should require that these 
evaluations be documented in a firm's records, and, if so, what type of 
records would be adequate to document that such an evaluation had 
occurred.
    In general, the comments opposed requiring manufacturers to 
establish procedures to identify, evaluate, and respond to potential 
safety concerns with dietary ingredients. Most comments claimed that 
such procedures are unnecessary because dietary ingredients have a 
history of safe use in food and that DSHEA is based on this history of 
prior use in food. Other comments argued that, because DSHEA is based 
on a history of prior use of existing dietary supplements and 
established a notification procedure for new dietary ingredients, a 
requirement concerning potential safety concerns for dietary 
ingredients would be beyond the scope of this rulemaking.
    Several comments noted that for those dietary ingredients that do 
not have a history of safe use in food and are considered ``new dietary 
ingredients,'' as defined in section 413(c) of the act, DSHEA 
established procedures for evaluating safety concerns. Section 
413(a)(2) of the act requires a manufacturer to submit a ``new dietary 
ingredient'' notification to FDA 75 days

[[Page 12172]]

before introducing or delivering a dietary supplement containing a new 
dietary ingredient into interstate commerce. The notification must 
provide the basis upon which the petitioner has concluded that the 
dietary supplement containing the new dietary ingredient is reasonably 
expected to be safe. Therefore, the comments argued that procedures to 
identify, evaluate, and respond to potential safety concerns are not 
necessary in a CGMP rule.
    Other comments stated that FDA should not require procedures to 
identify, evaluate, and consider potential safety concerns with dietary 
ingredients because manufacturers already have an essential and 
critical responsibility to substantiate the safety of the dietary 
ingredients they use in manufacturing a product. The comments suggested 
that FDA does not need to require written procedures because 
manufacturers must consult the generally known and generally available 
scientific literature to determine that a dietary ingredient is safe. 
Some comments suggested that, instead of FDA requiring safety 
evaluations, a third-party could evaluate safety concerns. Several 
comments suggested that manufacturers who use dietary ingredients that 
have little history of use in food in the United States should retain 
documentation concerning the dietary ingredient's safety. One comment 
suggested that we issue a guidance document to identify the types of 
acceptable ``history of use'' standards for dietary ingredients having 
little history of use in food in the United States and to describe the 
documentation that would be needed regarding a dietary ingredient's 
safety.
    Although the comments focused on the safety of using particular 
dietary ingredients, the safety concerns described in question 6 
actually consist of two concepts: (1) Is the product formulated using 
safe dietary ingredients; and (2) is the product manufactured, 
packaged, and held in a manner that would not adulterate or misbrand 
the product? The proposed rule focuses on safety concerns related to 
the latter concept. Specifically, the proposed rule focuses on the 
steps and processes used in the manufacturing, packaging, and holding 
of the product to ensure, for example, that the product has the 
identity, purity, quality, strength, and composition claimed and does 
not become adulterated or misbranded. The agency notes that no comments 
appeared to argue that safety issues relating to potential 
contamination or adulteration related to manufacturing processes are 
outside CGMPs. As the comments recognize, manufacturers have an 
essential and critical responsibility to substantiate the safety of the 
dietary ingredients they use in manufacturing a product.
    Section 402(g) of the act is not the only provision relevant to 
whether a dietary ingredient or dietary supplement may be deemed to be 
adulterated. Section 402(f)(1) of the act, in part, declares a dietary 
supplement to be adulterated if it:
    [sbull] Presents a significant or unreasonable risk of illness or 
injury under conditions of use described in the labeling or, if no 
conditions of use are suggested or recommended in the labeling, under 
ordinary conditions of use;
    [sbull] Is a new dietary ingredient for which there is inadequate 
information to provide reasonable assurance that the dietary ingredient 
does not present a significant or unreasonable risk of illness or 
injury; or
    [sbull] Is or contains a dietary ingredient that renders it 
adulterated under section 402(a)(1) of the act under the conditions of 
use recommended or suggested in the labeling. (Section 402(a)(1) of the 
act declares a food to be adulterated if it contains substances that 
are poisonous or deleterious substance that may render it injurious to 
health.)
    Additionally, section 301(a) of the act prohibits the introduction 
of adulterated food into interstate commerce.
    So, for a dietary ingredient or dietary supplement manufacturer to 
comply with sections 301(a) and 402(f)(1) of the act, it must take 
steps regarding potential safety concerns before it markets the 
product. Otherwise, if the manufacturer had no obligation to evaluate 
possible safety concerns before marketing a product, sections 301(a) 
and 402(f)(1) of the act would not make sense and the manufacturer 
would be acting contrary to the basic congressional intent behind 
DSHEA, which was to ensure that safe dietary supplements are available 
to consumers. For example, assume that a manufacturer wanted to market 
a new dietary ingredient but lacked evidence to show that it is safe. 
Under section 402(f)(1)(B) of the act, the manufacturer must have 
adequate information to provide reasonable assurance of the dietary 
ingredient's safety before it markets the dietary ingredient; 
otherwise, the dietary ingredient is adulterated under section 
402(f)(1)(B) of the act, and section 301(a) of the act would prohibit 
its sale in interstate commerce. Thus, the manufacturer has a statutory 
obligation to examine safety concerns relating to the dietary 
ingredients it uses before it markets the product.
    The proposed CGMP rule focuses on ensuring that the manufacturer 
knows what it is putting in its product and is manufacturing, 
packaging, and holding the product in a manner that will not adulterate 
or misbrand the product. For example, assume that you use a particular 
herb as your dietary ingredient. However, there are different species 
of that herb. Some species are poisonous; others are not. Additionally, 
there are variations within the same species of herb depending on where 
the herbs were grown. Some variants may contain higher levels of a 
particular dietary ingredient or marker compound than other variants. 
So, how do you know whether you have the right herb (nonpoisonous 
species of herb intended for use) and whether it meets your 
specifications? CGMPs would require that you check the identity of the 
herbs you receive; by doing so, you would be able to tell whether you 
have the correct herbs, whether your herbs are poisonous, or whether 
they meet your specifications. In this example, the potential safety 
concerns involve the dietary ingredient itself rather than any issue 
concerning contamination which would adulterate or may lead to 
adulteration of the dietary ingredient, and thus, the dietary 
supplement which contains the dietary ingredient.
    As for the comments' arguments concerning a dietary ingredient's 
history of use, we do not need to address history of use as part of 
this CGMP proposal. CGMPs focus on how a product is made under current 
manufacturing processes. A dietary ingredient's history of use does not 
provide any assurance that a particular product has the identity, 
purity, quality, strength, and composition that it purports to have. 
Further, history of use does not necessarily provide any assurance that 
a particular product would not pose a significant or unreasonable risk 
of illness or injury under conditions of use recommended or suggested 
in the labeling or under ordinary conditions of use.
    As for those comments discussing whether manufacturers or other 
parties should evaluate potential safety concerns, the proposed rule 
would require a manufacturer to evaluate a consumer complaint to 
determine whether the complaint relates to good manufacturing 
practices. Such an evaluation would include possible hazards to health 
resulting from the manufacturing, packaging, or holding of a product. 
Nevertheless, you should note that, insofar as compliance with the act 
and any CGMP regulations are

[[Page 12173]]

concerned, persons who market dietary ingredients and dietary 
supplements always remain responsible for their products. If the 
manufacturer markets the product, it would have to meet all proposed 
CGMP requirements, if the agency finalizes the rule as proposed. If 
another person buys a product (such as bulk dietary ingredients) from a 
manufacturer and distributes the product under its own name, that 
person must meet all applicable CGMP requirements.
    Question 7. We invited comment on whether specific controls are 
necessary for computer-controlled or assisted operations and how best 
to ensure that the software programs and equipment used to direct and 
monitor the manufacturing process are properly designed, tested, 
validated, and monitored.
    Comments generally supported specific controls for computer-
controlled or computer-assisted operations. One comment suggested 
requiring manufacturers to confirm, by adequate and documented testing, 
that their computer software programs perform their intended functions 
when computers are used as part of an automated production system 
having a significant and direct impact on product safety. Another 
comment suggested requiring that software programs and equipment used 
to direct and monitor manufacturing processes are properly designed, 
tested, evaluated, and monitored. The comment added that, if we 
consider imposing specific requirements on how firms document the 
adequacy of their computer-controlled or assisted operations, we should 
address those recommendations through a guidance document instead of 
issuing regulations.
    We agree that computer-controlled or computer-assisted operations 
need to be properly designed, tested, evaluated, and monitored to 
ensure that the computers do what they are supposed to do. 
Manufacturers should confirm, by adequate and documented testing, that 
their computer software programs perform their intended functions 
because computer use as part of an automated production system has a 
significant and direct impact on product safety. Computers are an 
important controlling piece of equipment in the manufacture of dietary 
supplements because they often direct and control key steps or 
processes in the manufacture of dietary supplements. If computers do 
not operate correctly, the dietary supplements manufactured using those 
computers may be adulterated.
    Several comments supported requirements for specific controls, but 
opposed using validation-of-operation mandates like those in the CGMP 
regulations for drugs. One comment suggested that we regulate computer-
controlled and computer-assisted operations for dietary supplements in 
the same way that we regulate such operations in the pharmaceutical 
industry, but only where an operation is directly related to the 
product's concentration or purity. One comment suggested that we 
consider adopting the computer-controlled and computer-assisted 
procedures specified in the proposed infant formula CGMP.
    We propose general requirements to ensure that equipment is 
suitable for its intended use. However, we seek comment, in the 
proposed rule, about whether we should include requirements, written 
procedures, and records for equipment verification and re-verification. 
We request comment on what verification manufacturers should be using 
in their computer-controlled or computer-assisted operations to ensure 
that a dietary ingredient or a dietary supplement that is produced is 
not adulterated during manufacturing. In addition, we request comment 
on whether we should issue guidance documents on verification 
procedures for use with computer-controlled or computer-assisted 
operations. Guidance documents generally represent FDA's advice or 
current thinking on a particular matter and are not binding on any 
person. In contrast, regulations create enforceable requirements that 
apply to all persons engaged in the same action or who make the same 
product.
    As discussed in greater detail later in this document, certain 
processes are necessary to ensure that computer-controlled or computer-
assisted equipment functions properly. This is because of the important 
role of such equipment in manufacturing. For example, if computer-
controlled or computer-assisted equipment is used to control 
components, inprocess materials, and rejected materials unsuitable for 
use, the operation must function as expected to ensure that components 
suitable for use in manufacturing dietary ingredients and dietary 
supplements are not mixed up with components held under quarantine such 
as those components that have been rejected as unsuitable for use. If 
computer-controlled or computer-assisted operations are used for the 
addition and mixing of components, they must function properly to 
ensure that the correct components are added and appropriately mixed to 
avoid producing a dietary ingredient or dietary supplement that is 
adulterated. Computer-controlled or computer-assisted operations are 
not perfect; computers are subject to malfunctions and ``bugs'' 
(errors) in the software they use. Problems with data entered into the 
computer may produce unreliable results. For these reasons, specific 
controls for computer-controlled or computer-assisted operations are 
necessary to prevent the manufacture of an adulterated dietary 
ingredient or dietary supplement.
    A few comments stated that no specific requirements for computer-
controlled or computer-assisted operations are needed because computer 
hardware and software are simply specialized plant equipment so that no 
special regulations are needed.
    We agree that computers are specialized pieces of plant equipment 
and, therefore, should be subject to additional requirements beyond 
those which would apply to plant equipment. Computers are specialized 
pieces of equipment because they are subject to malfunctions and 
``bugs'' (errors) in the software, they are reliant upon data entered 
into a computer, and they may be used to perform important roles such 
as component or dietary ingredient identification, measuring components 
and dietary ingredients, and quarantining materials. Consequently, 
proposed Sec.  111.30 would establish requirements for automatic, 
mechanical, or electronic equipment. The proposed requirements would 
cover, among other things, automatic equipment design, and routine 
calibration, inspection, and checks to ensure proper performance. As 
stated previously, we are seeking comment on whether we should include 
requirements for verification and re-verification of automatic, 
mechanical, or electronic equipment and processes and whether we should 
include requirements for computerized systems that are separate from 
requirements for other mechanical or automatic equipment. We discuss 
proposed Sec.  111.30 in greater detail later in this document.
    Question 8. We asked for comments on whether certain, or all, of 
the requirements for manufacturing and handling dietary ingredients and 
dietary supplements may be more effectively addressed by a regulation 
based on the principles of Hazard Analysis and Critical Control Point 
(HACCP), rather than the system outlined in the industry submission.
    In the ANPRM, we noted that, because of the wide variety of dietary 
ingredients and dietary supplements and because of the heterogenous 
composition of the dietary supplement

[[Page 12174]]

industry, CGMPs based on HACCP principles may provide a more flexible 
and less burdensome regulatory framework for manufacturers and 
distributors than the approach set out in the industry submission.
    Most comments opposed basing a CGMP regulation for dietary 
ingredients and dietary supplements on HACCP principles. Most comments 
supported applying traditional CGMP requirements on manufacturing, 
packaging, and holding to dietary ingredients and dietary supplements. 
In general, the comments that opposed requiring HACCP for dietary 
ingredients and dietary supplements asserted that: (1) A HACCP program 
would not be appropriate because HACCP focuses on microbial 
contamination of products that provide a favorable environment for 
growth of microbes that may be present, and these hazards are not a 
major concern for dietary supplements; (2) CGMPs are the best means of 
assuring the safety, quality, and composition of dietary ingredients 
and dietary supplements; (3) HACCP is not required for the food 
industry as a whole; and (4) HACCP would provide minimal incremental 
value at significant additional costs.
    Other comments opposed mandatory HACCP regulations for dietary 
ingredients and dietary supplements, but said manufacturers could 
implement voluntarily HACCP instead. One comment, which supported 
voluntary implementation of HACCP, wanted manufacturers to be exempt 
from having to disclose HACCP records to any Federal agency.
    HACCP principles can be applied to a broad range of manufacturing 
practices and HACCP principles are not solely focused on microbial 
contamination, but instead, are intended to identify and appropriately 
control steps in manufacturing where any type of adulteration can 
occur. Nevertheless, after considering the comments, we have decided to 
propose a CGMP approach for dietary ingredients and dietary 
supplements. We believe that CGMPs would establish a system of controls 
that, given the variations in size, technological sophistication, and 
regulatory experience among dietary ingredient and dietary supplement 
firms, would create a strong regulatory foundation throughout the 
industry.
    You may voluntarily choose to implement a HACCP plan that meets the 
requirements of the National Advisory Committee on Microbiological 
Criteria for Foods, however, proposed part 111 would still apply to you 
(Ref. 42). Any HACCP plans that also are intended to meet the records 
requirements under proposed part 111 would be treated as records under 
this proposal.
    Question 9. We invited comment on whether broad CGMP regulations 
will be adequate, or whether it will be necessary to address the 
operations of particular segments of the dietary supplement industry.
    Most comments supported broad CGMP regulations covering all 
segments of the dietary supplement industry instead of specific 
regulations tailored to distinct segments of the industry. One comment 
stated that the differences between distinct segments of the dietary 
supplement industry, such as manufacturers of raw materials or 
distributors of finished products, are no more pronounced than similar 
segments in the food industry. Another comment stated that having 
numerous CGMPs could subject raw materials and dietary ingredients to 
multiple CGMPs, thus making manufacturing operations more complex. This 
comment also questioned whether issuing multiple regulations is 
necessary or economically justified in an era of limited corporate and 
government regulatory resources. Other comments emphasized the 
importance of ensuring that all dietary supplement manufacturers (i.e., 
both small and large manufacturers, and foreign manufacturers planning 
to import dietary supplements into the United States) follow the same 
CGMP requirements.
    In contrast, some comments supported drafting regulations for 
particular segments of the dietary supplement industry. One comment 
stated that certain stages of the manufacturing process, such as the 
distribution of raw dietary ingredients, should be more strictly and 
comprehensively regulated than other stages because potential hazards 
are more prevalent during these manufacturing stages. The comment 
stated that conversely, the holding, distribution, and sale of a 
finished dietary supplement may require less comprehensive regulations 
because they are subject to fewer potential hazards. Other comments 
supported different levels of safety testing for different types of 
dietary supplement products. For example, some comments said that 
products such as melatonin and dehydroepiandrosterone resemble drugs, 
so we should require safety testing in animals and humans and impose 
druglike CGMP requirements for manufacturing. Another comment stated 
that less stringent CGMPs would be appropriate for herbal dietary 
supplements because they have long histories of food use and safety.
    We agree that some manufacturing operations are subject to greater 
hazards than others, and have drafted the proposed rule accordingly. 
For example, there are microbial hazards associated with raw 
botanicals. To address these hazards, the proposal would require that 
you perform tests on the botanicals. On the other hand, there are fewer 
hazards associated with holding and distributing finished dietary 
supplements, so the proposal would impose less comprehensive 
requirements for holding and distributing operations.
    We are persuaded by the comments that support a broad CGMP 
regulation as preferable to multiple regulations focused on particular 
segments of the industry. We agree with the comments that multiple 
regulations might be confusing and burdensome, especially to firms that 
manufacture products that fall into multiple categories. For instance, 
it would be easier for regulated firms and for us if firms were 
required to adhere to one set of CGMP requirements rather than follow, 
for example, one set of CGMP requirements for vitamins and a different 
set of CGMP requirements for minerals.
    We also recognize, though, that there may be some reasons to treat 
different types of dietary ingredients or dietary supplements 
differently in specific instances. For example, it may be appropriate 
to require one type of test for confirming the identity of amino acids 
and another type of test for confirming the identity of herbals. 
However, for the reasons discussed previously, we are proposing to 
establish one set of broad CGMP regulations for all types of products. 
Because we recognize that one set of specific requirements may not be 
appropriate for all types of dietary ingredients and dietary 
supplements, we have proposed regulations that allow manufacturers to 
develop practices to meet CGMP requirements. Depending on our 
experience with this proposed rule, we will consider whether we need to 
reevaluate our decision to establish one set of requirements for all 
dietary ingredients and dietary supplements.
    We agree with the comments that the proposed rule should not make 
any distinction between dietary ingredients or dietary supplements made 
in the United States and those made in a foreign country. The proposed 
rule would require that foreign firms that want to export dietary 
ingredients and dietary supplements to the United States manufacture, 
package, and hold dietary ingredients and dietary supplements 
consistent with proposed part 111. Moreover, under this proposed rule, 
if a U.S. firm contracts with a

[[Page 12175]]

foreign firm to
