Selenium Facts
Selenium a mineral and an important nutrient to fight diseases like cancer and heart disease. Selenium is synergistic with vitamin E, meaning that the two work stronger together. Both are potent antioxidants that help prevent or slow down aging and hardening of the tissues through oxidation. This trace mineral is essential to many body functions and can be found in every body cell, but especially in the kidneys, liver, spleen, pancreas, and testes. In males, approximately half of the body's selenium concentrates in the testicles and parts of the seminal ducts around the prostate gland.
How Selenium Works
Selenium works as an antioxidant with glutathione peroxidase to prevent damage by free radicals. It's involved in the metabolism of prostaglandins (hormone-like substances) which are used by the body in various ways. Selenium detoxifies toxic metals present in the body like arsenic and mercury.
