Viridian Selenium 200ug is a high-quality mineral supplement providing 200 micrograms of selenium per capsule in the organic, highly bioavailable selenomethionine form. Selenium is an essential trace mineral that acts as the catalytic centre of a family of important selenoprotein enzymes, including glutathione peroxidases and thioredoxin reductases, which are central to the body's antioxidant defence systems and the regulation of oxidative stress. Selenium contributes to the protection of cells from oxidative stress, and also contributes to the normal function of the immune system, normal thyroid function, normal spermatogenesis, and the maintenance of normal hair and nails. The thyroid gland has the highest selenium content per gram of any organ in the body, as selenium is essential for the enzymatic conversion of inactive T4 thyroid hormone to the metabolically active T3 form. Adequate selenium is therefore critical for normal thyroid function and the regulation of metabolism, body temperature, and energy production throughout the body. Selenium's antioxidant roles are extensive: it is an essential component of glutathione peroxidase, one of the body's primary antioxidant enzymes that neutralises hydrogen peroxide and lipid peroxides to protect cell membranes and DNA from oxidative damage. Selenium also interacts synergistically with vitamin E, another antioxidant, with the two nutrients potentiating each other's protective effects. Selenomethionine, the form used in this supplement, is the principal form in which selenium is found in foods and has superior bioavailability compared to inorganic selenium salts. This supplement contains 100% active ingredients, no artificial fillers, and is suitable for vegans. Produced in the UK to Viridian's strict ethical standards.
