SOD or Superoxide Dismutase is an antioxidant enzyme responsible for protecting you from dangerous superoxide free radicals. SOD is the frontline defense with other antioxidants like glutathione and catalase providing support, but SOD is the first. As we age we lose the ability to make more SOD causing all kinds of oxidative stress, damage, and inflammation. This may be the major cause of aging. But now, you can supplement with a truly POTENT version of SOD. VARS SOD from Physician Designed is here to SAVE you. See how well it helps you.
