Thompson's Organic Selenium 150 is an antioxidant formula that may assist in protecting cells from oxidative damage. Selenium supports the health and functioning of the liver as well as the immune, reproductive and cardiovascular systems. Selenium's primary function is to act as a vital Antioxidant and help inhibit the oxidation of fats. It works especially well when combined with another Antioxidant, Vitamin E. Selenium can also help protect the immune system by preventing the formation of free radicals that can cause harm to the body. Selenium deficiency has been linked to many disease states, along with being associated with exhaustion, impaired growth, high cholesterol levels, infections, and sterility. Due to Selenium being extremely low in New Zealand soils, it may be beneficial to supplement with this essential Mineral. Thompson's Organic Selenium 150 provides a scientifically validated dose of 150mcg.
