Prohibiting Tianeptine and Other Dangerous Products Act of 2026

This bill amends the Federal Food, Drug, and Cosmetic Act to prohibit specific dietary supplement practices. It directly affects supplement manufacturers and sellers by banning products marketed as dietary supplements that don't meet the legal definition (section 201(ff)) and prohibiting supplements prepared with help from individuals debarred under other laws. Key mechanisms include adding new prohibited acts (sections 301(jjj) and 301(kkk)) to strengthen import restrictions and seizure authorities for violative products. The law aims to enhance FDA enforcement against unsafe supplement practices without specifying outcomes or advocating for policy positions.
