Selenium

Selenium - 200mcg as l-selenomethionineSelenium is a natural antioxidant which delays the oxidation of polyunsaturated fatty acids and preserves the elasticity of tissue. Selenium is required in a number of metabolic processes including T4-T3 conversion.Qty:60DESCRIPTIONSelenium contains 200 mcg of bioavailable selenium per capsule. FUNCTIONSSelenomethionine is an amino acid containing selenium. Selenium is a nutritionally essential trace element for humans and animals. The National Research Council’s Recommended Dietary Allowance for selenium in adults ranges from 55 to 75 mcg per day depending on age and gender. In American adults, intakes typically range from 80 to165 mcg/d. Selenium is a cofactor to about 10 selenoproteins in the body; the most important of these appears to be glutathione peroxidase (GPX). GPX uses glutathione to reduce hydrogen peroxide and thus protect cells and plasma against free radical injury. GPX activity depends on an adequate supply of dietary selenium. Re
