What role does Vitamin E play in the body?

Vitamin E primarily functions as an antioxidant in the body. This means it helps protect cells from oxidative damage caused by free radicals, which are unstable molecules that can lead to cell inflammation and contribute to the development of various diseases, including cancer and heart disease. By neutralizing these free radicals, Vitamin E plays a critical role in maintaining overall health.

In addition to its role in protecting cells, Vitamin E supports immune function and has other important physiological benefits. It is often studied for its potential to promote skin health and improve the vascular system by supporting proper circulation.

While other vitamins and nutrients are associated with calcium absorption, thyroid regulation, and blood clotting — such as Vitamin D, iodine, and Vitamin K, respectively — these functions are not related to Vitamin E. Thus, recognizing Vitamin E's primary role as an antioxidant is essential for understanding its importance in nutrition and health.
