Description
Vitamin E refers to a group of ten lipid-soluble compounds that include both tocopherols and tocotrienols.[1] Of the many different forms of vitamin E, γ-tocopherol is the most common in the North American diet.[2] γ-Tocopherol can be found in corn oil, soybean oil, margarine, and dressings.[3][4] α-tocopherol, the most biologically active form of vitamin E, is the second-most common form of vitamin E in the diet. This variant can be found most abundantly in wheat germ oil, sunflower, and safflower oils.[4][5] As a fat-solubleantioxidant, it stops the production of reactive oxygen species formed when fat undergoes oxidation.[6][7][8] Regular consumption of more than 1,000 mg (1,500 IU) of tocopherols per day[9] may be expected to cause hypervitaminosis E, with an associated risk ofvitamin K deficiency and consequently of bleeding problems
