Selenium

Selenium is a trace mineral that is essential to good health but required only in small amounts. Selenium is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes.

What is Selenium?

Selenium is an essential trace element used in the proteins of many living organisms. The varied use of selenium in different organisms can be used to study evolution. The versatility of selenium also allows it to be used in medical research and treatment.
