Selenium is an important trace mineral we need on a daily basis. It is essential to the proper functioning of the immune system and thyroid gland, and it is a powerful antioxidant.
It is obtained from plants, seafood and meat; however, the level of selenium in the diet is significantly affected by the nutrient level in the surrounding soil. People who live in selenium-poor regions may require supplementation.
