Selenium is required to produce glutathione and helps with immune system function. Selenium is a trace mineral that is incorporated into important antioxidant enzymes. These enzymes aid the body in fighting cellular damage from free radicals. Our selenium is in the amino acid form L-selenomethionine, which research indicates is better absorbed and more bioavailable compared to other forms of selenium.*
- Potent mineral antioxidant
- Valuable cofactor in detoxification pathways*
- Nourishes and protects the immune system*

Description: Selenium is an essential trace mineral that is incorporated into important antioxidant enzymes and is required to produce glutathione. Metabolic Maintenance offers selenium in the amino acid form- L-selenomethionine- which is better absorbed and more bioavailable than other forms of selenium.
Uses: Selenium, as a component of selenoproteins, is a potent antioxidant. Selenium is essential for the formation and function of glutathione peroxidases, which detoxify hydrogen peroxide and fatty acid -derived hydroperoxides. Glutathione peroxidases help prevent oxidative damage to cell membranes and protect low density lipoprotein (LDL) from oxidation. Since oxidation of LDL is a factor in atherogenesis, selenium can contribute to cardiovascular health (1).
Selenium contributes to immune system function. In adult human subjects with relatively low Se levels, supplementation with Se (100 μg/day) augmented many host immune responses (increased IFN-g production, T cell proliferation to antigen stimulation and the percentage of total T cells, especially T helper cells). Se-supplemented subjects also exhibited rapid clearance of the poliovirus following immunization (2).
Selenium supports thyroid health. The thyroid is the organ with the highest concentration of selenium as selenoproteins. In addition to contributing to antioxidant defense in the thyroid, selenium also is incorporated into iodothyronine deiodinases, playing an essential role in the metabolism of thyroid hormones (3).
Selenium is a cofactor in detoxification pathways. Selenium has been shown to antagonize the effects of a number of toxic metals. Both arsenic (4) and mercury (5) toxicity have been counteracted by selenium supplementation.
Source Materials: Ascorbic acid is derived from corn sorbitol. L-selenomethionine is made by chemical synthesis. L-Leucine is made by sugar fermentation. Cellulose for capsules is derived from softwood tree pulp. All ingredients are vegan and non-GMO.
Allergens: According to information provided by our suppliers, these capsules are free of the eight major allergens as identified by the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA): Wheat (gluten), eggs, milk, soybeans, shellfish, fish, peanuts, tree nuts.
Recommendations: Use as directed by a healthcare professional.
Precautions: Pregnant or lactating women and individuals taking prescription medications should consult with a healthcare professional before taking any supplement.
