Sources
Polyunsaturated vegetable oils, seeds, nuts, and whole grains.
Therapeutic dosage
400 to 800 IU daily.

been suggested that a natural mixture of tocopherols - all in the

Safety concerns
Generally safe in the recomended doses. Careful with other "blood
thinning" drugs such as Coumadin or heparin and supplements
such as garlic and ginko biloba.
Interactions
May potentiate the blood thinning effect of Coumadin and heparin and
the supplements garlic and ginko biloba. You may need extra vitamin E
if you are taking clofibrate, colestipol, cholestyramine, or
isoniazid. It may interfere with the absorption of iron, so take at
different times of the day. If you take high doses (> 800 IU) you
may need extra vitamin K.
