For a more detailed explaination, visit http://www.vrp.com/tocota.htm, or take the short explaination below: Tocopherol is Vitamin E and Tocopheryl Acetate is a more stable form called Vitamin E Acetate. dl-alpha tocopheryl acetate is the acteate ester of synthetic vitamin E and d-alpha tocopheryl acetate is the acetate ester of natural vitamin E. The basic issue is that the synthetic form is cheaper to produce; however, some critics say the synthetic form is not as effective. There are a few other forms of tocopherol that occur in a variety of plants. I've seen references to Alpha, Beta, D-Alpha, Delta, Gamma and Zeta Tocopherols. Stephen (Steve) Duff [log in to unmask]
