[What is selenium?].

Selenium is a trace mineral. It works with Vitamin E. A normal body contains approximately 14mg of selenium. Why is Selenium important and what does it do in the body? Selenium is a vitally important trace mineral. It helps protect our cells against damaging particles in the blood system which are called free radicals or Reactive Oxygen Species (ROS). It thereby prevents cellular damage and premature aging. Selenium is especially important in the production of glutathione peroxidase, which helps to protect the body against the free radicals hydrogen peroxidase and hydroperoxide. Selenium also plays an important role in reducing the toxic effect from heavy metals such as cadmium, aluminum, mercury and lead. It can help the body to combat diseases such as cancer, cystic fibrosis, heart disease and rheumatoid arthritis and reduce susceptibility to infection and multiple sclerosis. It may also reduce menopausal discomfort, fatigue, low sexual potency and dandruff. Severe selenium deficiency is associated with Keshan disease (a heart muscle disorder affecting children) and Kashin-Beck disease, (a chronic bone disease in children). Males commonly require more selenium than females as it is used in the production of sperm and therefore lost in semen. There is little selenium in most vegetables since plants do not require it for growth.
