Warning Letter for Weight Loss Products
"Ultra Block 2000 plus C" and "Ultra Carbohydrate
Blocker 2000"


Online Superstore
c/o Tiffin International, Inc.
317 Susan Drive
Cinnaminson, NJ 08077

Dear Sir or Madam:

The Food and Drug Administration (FDA) has reviewed your web site at the address http://www.onlinesuperstore.com and has concluded that claims on this web site cause your products "Ultra Block 2000 plus C" and "Ultra Carbohydrate Blocker 2000" to be misbranded under the Federal Food, Drug, and Cosmetic Act (the Act). You can find the Act and FDA's regulations through links on FDA's Internet home page: http://www.fda.gov.

Under section 403(r)(6) of the Act, dietary supplement labeling may include claims about the supplement's effect on the structure or function of the human body (structure/function claims), provided that certain requirements are met. 21 U.S.C. § 343(r)(6)(A). One of these requirements is that the manufacturer of a dietary supplement bearing a "structure/function" claim must have substantiation that the claim is truthful and not misleading. 21 U.S.C. § 343(r)(6)(B).

The labeling of "Ultra Block 2000 plus C" and "Ultra Carbohydrate Blocker 2000" bears structure/function claims, including the following:

Ultra Block 2000 plus C

• "It blocks fat before it adds weight."
• "Chitin acts like a magnet, holding fat together and passing that pure fat out of your body safely before reaching your thighs, hips, waist, and rear."
• "Ours is one of the only ones with vitamin C which almost doubles chitosan's effectiveness as a fat blocker by boosting its swelling action, which in turn curbs the appetite and also enhances the fat absorbing ability."
• "[C]hitosan is magnetically attracted to lipids and has the ability, acting like a sponge, to significantly prevent fat in the digestive tract from being absorbed."

Ultra Carbohydrate Blocker 2000

• "Ultra Carbo Blocker 2000 acts on these excess carbohydrates helping them to pass through the system rather than storing them. This means you can still consumer your normal food intake, but may actually start to loose weight!"
• "Ultra [C]arbo Blocker 2000 can also reduce sugar cravings, stimulate weight loss. . . ."

We have reviewed these claims and have concluded that they are not supported by reliable scientific evidence. Because these claims lack substantiation, they are false or misleading, and cause your products to be misbranded within the meaning of sections 403(a)(1) and 403(r)(6)(B) of the Act. 21 U.S.C. § 343(a)(1), (r)(6)(B). It is a violation of section 301(a) of the Act to introduce or deliver for introduction into interstate commerce any food, including a dietary supplement, that is misbranded. 21 U.S.C. § 331(a).

This letter is not an all-inclusive review of your web site and the products that your firm markets. It is your responsibility to ensure that all products marketed by your firm comply with the Act and its implementing regulations.

The Act authorizes injunctions against manufacturers and distributors of illegal products and seizure of such products. 21 U.S.C. §§ 332, 334. You should take prompt action to correct any violations, including the violations identified in this letter. Failure to do so may result in enforcement action without further notice.

If you have scientific evidence which you believe substantiates that your claims for "Ultra Block 2000 plus C" and "Ultra Carbohydrate Blocker 2000" are truthful and not misleading, please provide it to us within fifteen (15) working days of receipt of this letter. Alternatively, please advise this office, in writing and within fifteen working days of receipt of this letter, as to the specific steps that you have taken to correct the noted violations and to ensure that similar violations do not occur in the future. If corrective action cannot be completed within fifteen working days, state the reason for the delay and the time within which the corrections will be made.

Your reply should be sent to the attention of Compliance Officer Quyen Tien at the above address.

Sincerely yours,


Joseph R. Baca
