Alpha-tocopherol is the most biologically active, and is the most widely distributed in nature. Natural alpha tocopherol is somewhat more active than the synthetic form. I do not know of any reason why mixed tocopherols should be preferred to pure alpha tocopherol, as there would be less biological activity in the mixed forms. Though it's preferable to get as much vitamin E as possible in the diet, there is considerable evidence that supplements are beneficial for most people. I recommend to my clients (unless allergies or other conditions are present) eating about a tablespoonful of mixed raw nuts daily, as well as green leafy vegetables. Experts in general agree that supplements of 100-200 mg/day. There is some evidence that high amounts can increase risk of stroke in some individuals. -- Kathrynne Holden, MS, RD Editor-in-Chief, "Spotlight on Food--nutrition news for people 60-plus" Tel: 970-493-6532 Fax: 970-493-6538 http://www.fortnet.org/~fivstar Contact Better Business Bureau of the Mountain States, < [log in to unmask]>
