Vitamin E is a fat-soluble vitamin and a powerful antioxidant that plays a crucial role in maintaining the health of cells and protecting them from damage caused by free radicals. It exists in several forms, with alpha-tocopherol being the most biologically active and commonly studied form.

Good dietary sources of vitamin E include nuts and seeds (such as almonds, sunflower seeds, and peanuts), vegetable oils (such as wheat germ oil and sunflower oil), leafy greens, and fortified cereals.

Vitamin E has many important functions in the body, including antioxidant protection, immune system support, and skin, heart and eye health.
