Selenium is a strong
antioxidant found in many natural sources, depending on how
abundant the selenium concentration is in a region's soil. The
soil in China, New Zealand and southeastern U.S. is particularly
selenium-deficient. Some studies have shown selenium to be an
effective supplement for preventing heart disease and cancer.

Selenium works in conjunction with vitamin E and is involved in
several enzyme systems. It is necessary for healthy skin,
muscles and heart function. Selenium promotes the formation of
antibodies and can help prevent infection. It also helps prevent
the absorption of metals such as mercury, silver and thallium
and may protect against prostate cancer.
Selenium deficiency can lead to premature aging, muscular aches,
nerve cell damage, mental retardation and infertility. It has
even resulted in myocardial deaths.
