Protanim is a patented dietary supplement that increases the body’s natural antioxidant defenses. According to the maker LifeVantage, Protandim is not an antioxidant per se, but provides antioxidant therapy by inducing the genes that encode a family of protective enzymes, including superoxide dismutase (SOD) and catalase (CAT). Protandim’s mechanism of action is to prevent free radical damage by increasing endogenous catalytic pathways, whereas traditional antioxidant supplements provide only stoichiometric scavenging of free radicals or other oxidants.
