Life Extension Se-Methyl L-Selenocysteine 200mcg
As an essential cofactor of glutathione peroxidase selenium is an important antioxidant. Selenium is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals. Other selenoproteins help regulate thyroid function and play a role in the immune system, DNA repair, and the detoxification of heavy metals. High doses of vitamin C (over one gram) may enhance the absorption of selenium. This mineral is best taken in conjunction with antioxidant supplements, such as vitamins C or E.
