The FDA Dietary Supplement Ingredient Advisory List is intended to quickly alert the public when the FDA identifies ingredients that do not appear to be lawfully included in products marketed as dietary supplements. Information about other ingredients and dietary supplement products that have been the subject of FDA action and/or statements can be found on the FDA Dietary Supplement Products & Ingredients page. For additional information about FDA’s evaluation of ingredients that were previously included in the Dietary Supplement Ingredient Advisory List, see Updates to the Ingredient Advisory List below.

Inclusion on the Dietary Supplement Ingredient Advisory List does not necessarily indicate that the FDA has determined that the ingredient is unsafe; it means FDA is taking steps to further evaluate the ingredient.
Ingredients are added to the Dietary Supplement Ingredient Advisory List based on a preliminary evaluation by the FDA. This preliminary evaluation indicates that an ingredient may not lawfully be in dietary supplements for reasons including:
- the ingredient appears to be excluded from use in a dietary supplement;
- the ingredient does not appear to be a dietary ingredient and does not appear to be either an approved food additive or generally recognized as safe for use; and/or
- the ingredient appears to be subject to the requirement for pre-market notification, but the requirement has not been satisfied.
Although this list reflects ingredients for which the FDA has made a preliminary assessment, it is not an exhaustive list of ingredients that may or may not be lawfully included in dietary supplements. Ingredients may be added to or removed from this list as the FDA continues its evaluation. To see a list of selected ingredients and dietary supplement products that the FDA has taken action on or has issued statements about, visit the FDA Dietary Supplement Products & Ingredients page.
The FDA welcomes additional feedback and information, including information that may support or refute the FDA's preliminary assessment regarding the ingredients on the Dietary Supplement Ingredient Advisory List. You may submit such information to the FDA's Office of Dietary Supplement Programs.

Consumers who have experienced a health-related reaction or illness (also known as an adverse event) after consuming any dietary supplement should contact their medical professional. It is important for consumers, health care professionals, and industry members to report adverse events to the FDA, so we can act to protect the public from unsafe products. You can report adverse events to the FDA by visiting the How to Report a Problem page.
