The Dietary Supplement Listing Act of 2024 requires manufacturers of dietary supplements to register their products with the FDA and submit detailed information about each supplement they sell. Manufacturers must provide the FDA with the supplement's name, ingredients, amounts, directions for use, warnings, allergen information, health claims, and a copy of the product label. This requirement applies to dietary supplements already on the market by January 1, 2025, with an 18-month deadline to submit listings, while new supplements must be registered at the time they enter the market. The FDA will create a publicly searchable database containing this information within two years of the law's enactment, though some confidential business details will be withheld. The legislation authorizes approximately $7.9 million for fiscal year 2024 and $6.6 million annually through 2028 to implement these requirements.
