Part 190PART 190—DIETARY SUPPLEMENTS

Part 190 outlines the requirements for dietary supplements, focusing on premarket notification for new dietary ingredients. Manufacturers or distributors must submit information to the FDA at least 75 days before introducing a supplement with a new dietary ingredient not previously in the food supply. This notification includes ingredient details, safety evidence, and recommended use conditions. The FDA acknowledges receipt and establishes a filing date, after which a 75-day period begins before the product can enter commerce. Substantive amendments reset this period. Information submitted is kept confidential for 90 days post-filing, after which it is publicly disclosed unless it constitutes trade secret or confidential commercial information. Failure of the FDA to respond does not imply safety or compliance.
