Vitamin E refers to a group of fat-soluble tocopherols and tocotrienols, with alpha-tocopherol being the most biologically active form. It is available as natural d-alpha-tocopherol from vegetable oil distillates or as synthetic dl-alpha-tocopheryl acetate produced by chemical synthesis.
Vitamin E is the body's primary lipid-soluble antioxidant, protecting cell membranes from oxidative damage. It is extensively used in dietary supplements, food fortification, animal feed premixes, and cosmetic products. Various commercial forms are available including oils, powders (CWS), and dry dispersible grades to suit different application requirements.
