Which vital mineral is involved in the body's antioxidant defense system?

Selenium plays a crucial role in the body’s antioxidant defense system. This mineral is a component of several selenoproteins, including glutathione peroxidase, which helps protect cells from oxidative damage by neutralizing harmful free radicals. By supporting the antioxidant enzymes, selenium contributes to maintaining cellular integrity and function, thus promoting overall health. Its antioxidant properties are essential for reducing inflammation and supporting immune function, highlighting its importance in various biochemical processes that protect the body from damage and disease.

While iron, magnesium, and zinc are vital minerals with important functions—such as transporting oxygen in the case of iron or participating in numerous enzymatic processes for magnesium and zinc—they do not have the same direct involvement in antioxidant defense mechanisms as selenium does.
