"Vitamin E forms are listed as either “tocopherol” or “tocopheryl” followed by the name of what is attached to it, as in “tocopheryl acetate.” The two forms are not greatly different; however, tocopherol may absorb a little better, while tocopheryl forms may have slightly better shelf life. Both forms are active when taken by mouth. However, the skin cannot utilize the tocopheryl forms, so those planning to apply vitamin E to the skin should buy tocopherol. In health food stores, the most common forms of vitamin E are d-alpha tocopherol and d-alpha tocopheryl (acetate or succinate). Both of these d (natural) alpha forms are frequently recommended by doctors of natural medicine."
I think the only chemical difference is the -pheryl is esterified. If it's d-alpha, not dl-alpha, that means it's in its natural form. You're still good.
