Selenium is a trace mineral that is required in small amounts. It is an important nutrient that combines with protein to functions as an antioxidant to help protect the cells in your body from free radical damage. Selenium is also essential for normal thyroid function. Selenium works stronger as a pair with vitamin E. Both Selenium and vitamin E are potent antioxidants that help to slow down aging and hardening of the tissues through oxidation. This trace mineral is thought to detoxify toxic metals from the body, like mercury and arsenic, and it is essential to many of the body’s functions and can be found in every cell, but particularly in the liver, kidneys, pancreas, spleen, and testes.
Some research indicates there may be a lower risk of cancer and heart disease among people who have larger amounts of selenium in their diets.
