    An Essential Mineral that is heralded for its anti-oxidant capabilities, it forms a part of some anti-oxidant enzymes such as glutathione to confer protective effects. Taking more than needed, however, can cause oxidative damage and may be pro-diabetic.

    An overall intake (foods and supplements) in the range of 200-300ug daily should be the goal for general health and well being with an emphasis on anti-carcinogenic properties.
