Food State Selenium is presented to the body complete with all the amino acids & other phyto-nutrients with which this mineral is found in food. It is hence far better absorbed & used than inorganic selenium.• It is a powerful antioxidant; • It works synergistically with vitamin E; • It assists in keeping blood vessels healthy, so is connected to the circulatory system; • In males, selenium is concentrated in the male testes & seminal glands & is lost in the semen; • It is now known to have a significant role in both male & female fertility. Selenium is an essential mineral, found in minute amounts in the body. It closely resembles sulphur in its physical properties. Selenium functions either alone or with enzymes. Selenium is a natural antioxidant that protects against free radicals & appears to preserve elasticity of tissue, which becomes less elastic with ageing. It is a key nutrient in immunity. Selenium works closely with vitamin E in actions like the production of antibodies, the binding of toxic metals such as mercury, amino acid metabolism & the promotion of normal body growth & fertility. Selenium maintains certain energy-producing cells, including those of the heart, by ensuring an adequate oxygen supply. Selenium is necessary for the production of prostaglandins.
