What is the function of vitamin E in the body?

Vitamin E plays a crucial role in protecting cells from oxidative damage. It is a powerful antioxidant that helps neutralize free radicals in the body, which are unstable molecules that can cause harm to cell structures, lipids, and DNA. By mitigating oxidative stress, vitamin E supports overall cellular health and helps maintain the integrity of various biological systems.

In contrast, the other options focus on different physiological functions. Bone strengthening relates more to vitamins like D and K, which are directly involved in calcium metabolism and bone health. Protein synthesis is primarily associated with amino acids and various B vitamins, such as B6, B12, and folate. Boosting immune response is indicative of vitamins such as A, C, and D, each playing distinct roles in regulating immune function. Thus, the unique role of vitamin E in combating oxidative damage clearly distinguishes it from these other functions.
