  • An advanced form of supplemental selenium



  • Important natural antioxidant



  • Vegetarian capsules


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. Se-Methyl L-Selenocysteine (SeMC) is a naturally occurring seleno-amino acid that is synthesized by plants such as garlic and broccoli. SeMC is an organoselenium compound and also more bio-absorbable than other forms. It is also fully available for the synthesis of selenium-containing enzymes, such as glutathione peroxidase.

My favorite amongst a large selection After taking selenium supplements for more than 30 years, this newer one is my favorite. Capsule pulls apart easily so I can spread dosage out to 4 times per day. April 21, 2013
Switching to this now I'm switching to this form of selenium going forward. It is more bio-available than regular selenium. March 3, 2013
