Superoxide Dismutase (SOD) is our body’s most potent primary antioxidant. This critical enzyme and its two vital counterparts, Catalase and Glutathione (GPx), reduce free radicals into harmless elements. Unlike external antioxidant supplements, Superoxide Dismutase (SOD), Catalase, and Glutathione (GPx) are produced by our cells and are millions of times more effective than dietary antioxidants at reducing oxidative stress.
