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; 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.
