I think the type of Vitamin E is what is really suspect here. Many supplements use a synthetic dl-tocopherol which is not good. The d-tocopherol is better being natural. But the real problem is the concentration of the one type of Vitamin E. There probably needs to be a blend of Vitamin E's in the way they actually occur in nature. A Vitamin E supplement with a range of Tocopherols, alpha, beta, and gamma with a range of Tocotrienols, alpha, beta, and gamma are the best. Plus there are apparently heart benefits to the mixed Vitamin E's. Remember that A, E, D, and K are fat soluble so you should take care to only use the recommended amount. Too much can cause all kinds a disorders, possibly cancer too, after long-term misuse. Nearly all studies I've read involve Vitamin E in either the dl or d form of tocopherol and not a mixed formula. Some Doctors think this is a flaw in Vitamin E research, as well.
Here's an article on Vitamin E...

Some would argue that a balanced diet is good enough. Personally, I think there is some benefit to supplementing certain vitamins given specific circumstances, but you definitely have to do your homework.
