Selenium is an essential mineral found in small amounts in the body.
Known functions in the body of selenium include functioning as an antioxidant, helping to repair damaged cells and DNA.

It’s also critical in reproduction and DNA synthesis as well as immune function.
Selenium exists in two forms, both of which are good dietary sources, inorganic (selenate and selenite) and organic (selenomethionine and selenocysteine)
