Protandim is a herbal dietary supplement marketed with unsupported claims that it can treat a number of medical conditions. The product is a patented mix of five herbal ingredients and sold by LifeVantage Corporation, a Utah-based multi-level marketing company. The manufacturers of Protandim make no claims that it can prevent or cure any medical conditions. In 2017, LifeVantage was issued a warning letter by the U.S. Food and Drug Administration (FDA) regarding illegal advertising claims on the company's websites suggesting that Protandim can help to cure various ailments, including cancer and diabetes.
