Selenium, New RDA* 55µg
Selenium acts as a micronutrient or trace element in the human body. Its distribution in the earth's crust varies from place to place. Its content of water varies even more greatly. The amount present in foods also varies widely. Males appear to have a greater need for this mineral. About half the supply of their bodies is concentrated in the testicles and parts of the seminal ducts adjacent to the prostate gland.
Selenium is a grey, crystalline element of the sulphur group. It is an antioxidant and its biological activity is closely related to vitamin E. It is excreted in the semen.
Selenium is found in soils and rocks and consequently may then accumulate in plants.
