For you, if you are looking for an advanced and quickly-absorbable form of the antioxidant selenium

The advanced Se-Methyl L-Selenocysteine can:
  • Encourage healthy cell function & division

  • Protect cells & tissues from oxidative damage

  • Promote immune function & health

  • Optimize thyroid hormone synthesis & activity

Se-methyl L-selenocysteine is a naturally occurring compound of selenium, and is synthesized by plants such as broccoli and garlic. Selenium is an essential micronutrient for your body, incorporated into enzymes and other proteins to create antioxidant enzymes called selenoproteins, which can help block cellular damage from free radicals.

Product details:
A key micronutrient for selenproteins

Selenium is an essential trace mineral involved in numerous biological functions. In the body, it's incorporated into enzymes and proteins to form selenoproteins, such as the antioxidant enzyme glutathione peroxidase. This enzyme uses four units of selenocysteine to neutralize free radicals through glutathione. (1,2)

By balancing cellular oxidation and reduction reactions, glutathione peroxidase and other selenoproteins help safeguard tissues and cells from oxidative stress and promote healthy cell function and division. (1-3)

Selenium & thyroid function

Selenium, as selenocysteine, is also a component of enzymes involved in activating thyroid hormones. Selenium can support metabolism, mood, and cognitive health by protecting thyroid gland function and optimizing thyroid hormone synthesis and activity. (2,4,5)

Immune health & vitamin synergy

Keeping an optimal selenium status contributes to immune regulation by stimulating T cells, natural killer (NK) cells, and other immune cells. 

Selenium also encourages healthy inflammatory immune activity and works synergistically with vitamin E to protect lipids and promote immune health. (2,6-9) Its bioavailability and absorption are enhanced when taken with vitamins A, C, D, and E. (2)

An organic compound

Se-methyl L-selenocysteine (MSeC) is a plant-based selenium compound found in garlic and broccoli and has demonstrated positive effects on cell function. (1) It's more bioavailable than inorganic selenium salts typically used in supplements. 

Unlike selenomethionine, MSeC is closely related to the physiologic form, selenocysteine, that is needed to produce selenoproteins such as glutathione peroxidase. (11,12)
