The eight molecules that make up vitamin E are alpha, beta, gamma, and delta-tocopherol as well as alpha, beta, gamma, and delta-tocotrienol. Out of the eight compounds, only alpha-tocopherol is known to satisfy nutritional requirements in humans. After the small intestine absorbs all forms of vitamin E, the liver solely metabolizes alpha-tocopherol. The leftover vitamin E forms are then eliminated by the liver.[1][2][3][4] Human vitamin E insufficiency is exceedingly uncommon since low vitamin E diets are unlikely to be the cause. Rather, abnormalities in the metabolism or absorption of dietary fat are typically the reason. Vitamin E is a vitamin that dissolves in fat. Vitamin E might play a part in decreasing the incidence of ischemic heart disease and atherosclerosis.
