On Oct. 1, 2024, the FDA began implementing a reorganization impacting many parts of the agency. We are in the process of updating FDA.gov content to reflect these changes.
The U.S. Food and Drug Administration issued 12 warning letters and 5 online advisory letters to foreign and domestic companies that are illegally selling more than 58 products, many that are sold as dietary supplements, which are unapproved new drugs and/or misbranded drugs that claim to prevent, treat or cure Alzheimer’s disease and a number of other serious diseases and health conditions. These products, which are often sold on websites and social media platforms, have not been reviewed by the FDA and are not proven safe and effective to treat the diseases and health conditions they claim to treat. These products may be ineffective, unsafe and could prevent a person from seeking an appropriate diagnosis and treatment.
