What is the function of Vitamin E in the body?

Vitamin E serves a crucial role in the body primarily as an antioxidant. This means it helps to neutralize free radicals—unstable molecules that can cause oxidative damage to cells. By doing so, Vitamin E supports cellular integrity and protects the body from various chronic diseases, including heart disease and cancer.

Antioxidants are essential in combating oxidative stress that occurs from environmental factors or metabolic processes. Vitamin E is found in various food sources, including nuts, seeds, and green leafy vegetables, and is also present in some dietary supplements, further highlighting its importance in maintaining health.

The other choices pertain to functions that are either not related to vitamin E or are associated with other vitamins and minerals, which helps clarify why the focus is on Vitamin E's antioxidant properties.
