SOD superoxide dismutase has antioxidant, anti-aging and anti-inflammatory properties. Superoxide dismutase (SOD) is an acidic protease, widely found in living organisms, with catalytic scavenging of superoxide anion free radicals, antioxidant, anti-aging, anti-inflammatory, and protection of cells from damage. 1. Antioxidant, anti-aging: SOD can remove and reduce excessive free radicals in the body so as to slow down the aging process and achieve the effect of anti-aging; it can also remove the superoxide generated by free radicals in the body, and with the growth of age SOD superoxide dismutase will show a downward trend. 2. Anti-inflammatory: such as SOD can inhibit arthritis, reduce the deposition of IgG in the glomerulus, but also be able to inhibit xanthine-induced acute bronchitis caused by organ permeability changes, reduce the accumulation of polymorphonuclear leukocytes in the lungs.
