Protandim is a patented dietary supplement marketed by LifeVantage Corporation (NASDAQ: LFVN; formerly LifeLine Therapeutics and Yaak River Resources, Inc), a Utah-based multilevel marketing company. The manufacturers of Protandim claim the product can indirectly increase antioxidant activity by upregulating endogenous antioxidant factors such as the enzymes superoxide dismutase (SOD) and catalase, as well as the tripeptide glutathione. Like all dietary supplements, Protandim has not been evaluated by the U.S. Food and Drug Administration (FDA) and "is not intended to diagnose, treat, cure, or prevent any disease."
