In what process does selenium play a critical role?

Selenium plays a critical role in the antioxidant system of the body. As a key component of selenoproteins, selenium is involved in the synthesis of several enzymes that help protect cells from oxidative damage. One of the most well-known selenoproteins is glutathione peroxidase, an enzyme that helps to neutralize harmful hydrogen peroxide and lipid peroxides, thereby reducing oxidative stress and mitigating damage to cellular components like DNA, lipids, and proteins.

This protective role is essential in preventing chronic diseases and supporting overall health, as excessive oxidative stress can lead to inflammation and a variety of health issues. The antioxidant properties of selenium make it vital for maintaining proper cellular function and protecting against damage caused by free radicals. This is why selenium is recognized for its critical involvement in the antioxidant system.
