Many products currently available derive their superoxide dismutase from an animal source, porcine, which comes from pigs. Our S.O.D. Plus is isolated from the fruit of the Rosa roxburghii plant!
Independent testing has shown that our S.O.D. Plus contains the highest source of S.O.D. activity out of any natural source! That's 4,000 units of superoxide dismutase like activity per capsule!
