What is the primary function of Vitamin E in the body?

Vitamin E is primarily recognized for its role as an antioxidant vitamin in the body. It helps protect cells from oxidative stress and damage caused by free radicals, which can lead to chronic diseases and aging. Vitamin E achieves this by neutralizing free radicals, thus maintaining the integrity of cellular membranes and preventing oxidative damage to fats in the body, particularly polyunsaturated fatty acids.

Additionally, while vitamin E does support immune function and has some association with other biological processes, its defining characteristic is its potent antioxidant capability. Therefore, identifying it as an antioxidant underscores its critical protective role against oxidative damage, which is crucial for overall health and may contribute to reducing the risk of certain diseases and maintaining aging healthily.
