Which fat-soluble vitamin acts as an antioxidant and supports cellular health?

Vitamin E is a crucial fat-soluble vitamin known for its role as an antioxidant, which helps protect cells from oxidative damage caused by free radicals. This protective function is vital for maintaining cellular health and reducing the risk of chronic diseases that can arise from oxidative stress.

As an antioxidant, Vitamin E donates electrons to free radicals, neutralizing them and preventing cellular damage. This process is particularly important in lipid-rich areas of the body, such as cell membranes, where lipid peroxidation can significantly impact cellular function.

In contrast, while Vitamin A is important for vision and immune function and Vitamin D plays a role in calcium metabolism and bone health, they do not primarily function as antioxidants. Vitamin C, although it also acts as an antioxidant, is water-soluble and not classified within the fat-soluble vitamins. Therefore, Vitamin E stands out as the correct choice due to its specific properties related to antioxidant activity and support for cellular health.
