Prohibiting Tianeptine and Other Dangerous Products Act of 2026

This bill amends the Federal Food, Drug, and Cosmetic Act to add two new prohibitions for dietary supplements. It bans introducing into interstate commerce any product marketed as a dietary supplement that doesn't meet the legal definition (Section 201(ff)), and prohibits supplements prepared, packed, or held using a person banned from the industry (Section 306). These changes update import restrictions (Section 801) and seizure authorities (Section 304) to include violations of these new prohibitions. The law directly affects dietary supplement manufacturers, distributors, and sellers who handle products meeting these specific criteria.
