GliSODin is a potent form of Superoxide Dismutase (SOD). SOD is a protein antioxidant that builds a cellular protective mechanism against superoxide radical, the most common form of free radical in the body. Oxidative stress accelerates the degeneration of cells because of damage to the DNA. GliSODin has been shown to modulate the antioxidant activities of SOD, as well as Glutathione and Catalase.
