Selenium

Selenium is a trace mineral that plays a key role in helping maintain proper levels of the powerful antioxidant enzyme glutathione peroxidase. It works with antioxidants C, E and A. The combined effect of Selenium and vitamin E is greater than the affect of each alone.

Selenium fed to cells increases their levels of antioxidant enzymes and prevents damage caused by radiation and chemical carcinogens. Deficiency in humans correlates with higher rates of colon, breast, ovary, prostate, lung, bladder and skin cancer. Studies show it can prevent cancer in both animals and humans.
