To amend the Federal Food, Drug, and Cosmetic Act to establish new prohibited acts relating to dietary supplements.

This bill (HR 8123) amends the Federal Food, Drug, and Cosmetic Act to add two new prohibitions for dietary supplement products sold across state lines. It makes it illegal to sell: (1) any product marketed as a dietary supplement that doesn't meet the legal definition of one, and (2) any dietary supplement prepared, packed, or held using a person banned under Section 306. The bill also updates import rules and seizure authorities to specifically target these new violations. These changes directly affect dietary supplement manufacturers, sellers, and distributors who fail to meet the legal definition or use banned personnel in production.
