By balancing cellular oxidation and reduction reactions, glutathione peroxidase and other selenoproteins protect cells and tissues from oxidative damage and support healthy cell function and cell division.^1-3  

Forms of Selenium

Selenium, as selenocysteine, is also part of an enzyme that helps regulate the activation of thyroid hormone.² Selenium helps with maintenance of healthy cognition, mood and metabolism by protecting thyroid gland function and optimizing thyroid hormone synthesis and activity.^2,4,5

Combining with Vitamins

Maintaining optimal selenium status can help ensure proper regulation of the immune system. In addition to stimulating T cells, natural killer (NK) cells and other immune cells, selenium also supports healthy inflammatory immune activity.^6,7 Selenium appears to act synergistically with vitamin E to protect lipids and support immune health.^2,8,9 Its absorption and bioavailability are increased in the presence of vitamins A, C, D and E.²

Organic compound

Se-Methyl L-Selenocysteine (MSeC) is a naturally occurring selenium compound that is synthesized by plants such as garlic and broccoli and has demonstrated positive effects on cell function.¹⁰ As an organic selenium compound, MSeC is more absorbable than inorganic selenium salts typically used in supplements.² Unlike selenomethionine, MSeC is closely related to the physiologic form, selenocysteine, needed to synthesize selenoproteins such as glutathione peroxidase.^11,12
