FDA Launches New Directory of Ingredients Used in Products Marketed as Dietary Supplements

What's New

February 21, 2024

Today, the U.S. Food and Drug Administration (FDA) has updated the agency’s Ingredient Directory, including renaming the web page to be Information on Select Dietary Supplement Ingredients and Other Substances. These changes are the result of some constructive stakeholder feedback received since we initially published the directory. In addition to the new title, the directory updates include adding categories to classify the type of FDA action or communication for each listed ingredient; recording the date each listed ingredient was added to the directory; and streamlining the introductory text on the page.

Original Constituent Update

March 6, 2023

Today, the U.S. Food and Drug Administration (FDA) is unveiling its new Dietary Supplement Ingredient Directory, a webpage where the public can look up ingredients used in products marketed as dietary supplements and quickly find what the FDA has said about that ingredient and whether the agency has taken any action with regard to the ingredient. The directory is in list form and includes links to the agency’s actions and communications for each ingredient on the list. If there is a separate FDA webpage for the ingredient, the directory links to that page. The directory is intended to be a one stop shop of ingredient information that was previously found on different FDA webpages. This directory is intended to help manufacturers, retailers, and consumers stay informed about ingredients that may be found in products marketed as dietary supplements and quickly locate information about such ingredients on the FDA’s website.

It is important to note that the directory is not intended to be a comprehensive list of all ingredients used in products marketed as dietary supplements and may not include all actions the agency has taken with respect to a particular ingredient. For example, all actions may not be listed if the agency has taken many similar actions and some older actions may not be listed, especially if they do not reflect the agency’s current position. The FDA will update the directory periodically to reflect new developments.

As the agency is instituting the Ingredient Directory, we are also retiring the FDA Dietary Supplement Ingredient Advisory List, which was a rapid-response tool meant to quickly alert the public when the agency identified ingredients that did not appear to be lawfully marketed in dietary supplements. Anyone who signed up for the Dietary Supplement Ingredient Advisory listserv will automatically receive updates to the Ingredient Directory as they become available.

The FDA welcomes additional feedback and information regarding these ingredients. You may submit such information to the FDA's Office of Dietary Supplement Programs.
