Quizplus · Accepted Answer

Vitamin E is a fat-soluble vitamin that acts as an antioxidant in the body. It helps protect the body's cells from damage caused by free radicals, unstable molecules produced during normal metabolism and exposure to environmental toxins. Vitamin E guards cell membranes, body proteins, DNA, and cholesterol from free radicals and thus helps prevent chronic diseases such as heart disease, cancer, and macular degeneration. Thiamin, vitamin D, and vitamin K do not have the same antioxidant properties as Vitamin E.
