Vitamin E is not bad for you.
Taking large amounts of it is.
In fact, toxicity can result from taking large amounts of any vitamin or mineral, even vitamins that are water soluble. Although nutrient requirements vary from person to person, Tolerable Upper Intake Levels (ULs) are established so that people do not overconsume nutrients with the foolish belief that, because some is good, more is better.
Furthermore, like anything, our bodies require a balanced system of essential resources on which to function. For a healthy person, high-dose supplements will disrupt that balance. High-doses are reserved for theraputic purposes.
So it’s not a question of whether or not Vitamin E is intrinsically bad or good; it’s a matter of how much Vitamin E is bad and/or good.
If someone is concerned over whether or not they should supplement with Vitamin E, my opinion is to take a daily multivitamin that includes it and, of course, eat a diet that incorporates Vitamin E-rich foods.
You’ll have your bases covered.
