evidence: Alzheimer’s disease, dementia, and memory loss are conditions for which science has no cure. The FTC and the FDA have issued warning letters to some companies that have made claims — with no proof — that their products can treat or cure Alzheimer’s disease and other conditions. The truth is: [...] If you or someone you love has cancer, know that scammers often try to take advantage of the anxiety and worry that often comes with a diagnosis. You may be tempted to try supposed "miracle" cancer-fighting products — like pills, powders, and herbs — that you’ve seen advertised or heard about from family and friends. Maybe you’ve even heard about some foreign clinics offering supposed "miracle" treatments not available in the U.S. Whether you’re looking in the U.S. or abroad, know this: [...] Under federal law, no one can promote dietary supplements for the treatment of a disease. That’s because supplements aren't proven to be safe and effective. Dishonest companies may make false claims like: "Helps prevent Alzheimer’s disease," "stop arthritis pain forever," "cures eye disease," "traditional remedy for heart disease, prostate cancer, erectile dysfunction," and "prevents allergies." If you spot those claims, stop and tell the FTC at ReportFraud.ftc.gov.
