Overcoming the free radical threat.

Overcoming the Free Radical Threat

The body has an antioxidant defense system consisting of enzymes and nutrients that protects the body from oxidative cell damage. When there is an ample supply of these antioxidants, free radical damage is not a problem. But Dr. Lester Packer of the University of California at Berkeley has demonstrated in his studies of runners and cyclists that the body's antioxidant supply gets used up more quickly under conditions of increased oxygen consumption during exercise. Packer found that increasing the intake of certain nutrients - especially vitamin E - helps bolster antioxidant defenses and protects against cell damage.

Another study evaluated the antioxidant protective role of vitamin E following strenuous exercise by male college students. Writing in the International Journal of Biochemistry, Satoshi Sumida and colleagues concluded that free radical reactions associated with heavy exercise can be inhibited by dietary supplementation with vitamin E.
