Selenium

Selenium is an essential trace element functioning as a cofactor for several enzymes called selenoproteins. These selenoproteins play critical roles in various physiological processes, including antioxidant defense, thyroid hormone metabolism, and immune function. Selenium contributes to protecting cells from oxidative damage, a process linked to aging and various chronic conditions. Adequate selenium levels are necessary for optimal health, supporting the body's ability to maintain cellular integrity and proper metabolic function.
