Vitamins and supplements, with safety first. The FDA does not approve supplements before they are sold, and no supplement may legally claim to cure or treat a disease. Weight loss, sexual and bodybuilding products are the most likely to hide real drugs. Look for a USP Verified or NSF seal, ask your doctor or pharmacist about interactions, and report bad reactions to FDA MedWatch. Brands and stores below are commercial.
