Se-Methyl L-Selenocysteine 200 mcg 90 caps by Life Extension

Selenium is an essential mineral that functions as a critical component in antioxidant enzymes, most notably glutathione peroxidase. This action helps maintain cellular health by assisting in the management of damage caused by free radicals. Selenium is incorporated into various proteins to create selenoproteins, which are central to the body's natural defense against oxidative stress.

For effective supplementation, bioavailability is key. Life Extension's Se-Methyl L-Selenocysteine 200 mcg offers a highly bioabsorbable form of selenium. This naturally occurring seleno-amino acid, unlike selenomethionine, is not incorporated into structural proteins. Instead, it remains fully available for the direct synthesis of crucial selenium-containing enzymes, such as glutathione peroxidase. This ensures the body can efficiently utilize the selenium to support its antioxidant capacity.
