Vitamin E is a fat-soluble vitamin.
Vitamin E is a family of compounds that includes alpha tocopherol, beta tocopherol, gamma tocopherol, delta tocopherol, and four tocotrienes. Synthetic vitamin E is slightly less potent than natural vitamin E but is less expensive. Vitamin E is one of the most potent fat-soluble antioxidants in the body. As an antioxidant, vitamin E protects the fatty areas of the body from damaging compounds called free radicals. Vitamin E helps protect red blood cells from damage.
