Which trace minerals are essential for antioxidant functions in the body?

Zinc and selenium play crucial roles in the body's antioxidant defense systems. Zinc is an integral part of various antioxidant enzymes, including superoxide dismutase (SOD), which helps neutralize free radicals. It also aids in the stabilization of cellular membranes and promotes the activity of other antioxidant compounds.

Selenium is essential for the synthesis of selenoproteins, which have antioxidant properties. One well-known selenoprotein is glutathione peroxidase, which protects cells from oxidative damage by reducing hydrogen peroxide and lipid peroxides.

The combination of zinc and selenium contributes significantly to the body's ability to counteract oxidative stress, thus supporting overall health and preventing damage caused by free radicals. This is why the answer regarding these two trace minerals as essential for antioxidant functions is accurate.
