Product Overview


  • For Longer Life
  • Advanced Form of Selenium
  • Dietary Supplement

As an essential cofactor of glutathione peroxidase,86 selenium is an important antioxidant.87 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.87-91 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.92,93
Se-Methyl L-Selenocysteine (SeMC) is a naturally occurring seleno-amino acid that is synthesized by plants such as garlic and broccoli.95-98 SeMC is an organoselenium compound and also more bioabsorbable than other forms. Unlike selenomethionine, which is incorporated into proteins in place of methionine, SeMC is not incorporated into any proteins ... so it is fully available for the synthesis of selenium-containing enzymes, such as glutathione peroxidase.99

Good price for this highly bioavailable source of selenium. I take 100mcg daily by carefully pulling the capsule open and pouring half of the powder on to a spoon. If you do this, be careful as the powder is very fine and can easily be blown away. First time iherb shoppers may use my coupon code, HEM053 for a discount on their order.

I like to mix a half a capsule of this form of selenium with a half a capsule of selenomethionine, and a half a capsule of sodium selenite. Each form of selenium is used a bit differently by the body, so I figure why not try to cover all the bases.
