Selenium is essential to mammals and higher plants in small amounts.
It is said to stimulate the metabolism, and is an anti oxidant, protecting cells and tissues from damage wrought by free radicals. Because its anti oxidant effects complement those of Vitamin E, the two taken together, help reinforce each other. These two compounds together are extremely important in preventing free radical damage to cell membranes. Selenium also supports immune function and neutralizes certain poisonous substances such as cadmium, mercury, and arsenic that may be ingested or inhaled. Although it's full therapeutic value is unknown, adequate selenium levels may help combat arthritis, deter heart disease , prevent cancer and regulating HIV expression .
