This Week’s Feature: Superoxide Dismutase (SOD).
SOD is an endogenous antioxidant present in almost every living organism. It provides defense against oxidative stress which comes from free radicals. SOD levels decrease as we age and at the same time free radical level increase. Once produced, free radicals are removed by antioxidant defenses. When delicate SOD molecules are coupled with a protein from wheat and in plants, they can be delivered intact to the intestines and once in circulation they go to work detoxifying potential harmful substances and reducing oxidative stress and crippling diseases such as atherosclerosis, stroke and arthritis (Dale Kiefer, LE Magazine June 2006). Researchers believe that SOD decreases with aging (A-Sanchez M et al 2005, Eur J Clin Nutr 59 Suppl 2S58-S62; Levin ED 2005; Curr Alzeimer Res 2: 191-6) and evidence suggests that boosting falling SOD levels may help guard against disease and extend life span.
