Much, if not most, of the Vitamin E supplements you’ll find at your local drug or grocery store is comprised of an inferior form. Let’s make sure you’re using the best type.
(For purposes of this article I’m referring to alpha tocopherol as vitamin E, which is the form that the RDA is based on.)
There are two types of alpha tocopherol: there’s the natural version – d alpha tocopherol, and there’s the synthetic form – dl alpha tocopherol.
As you might guess, the natural version is better…roughly twice as good according to most studies/sources.
So if/when you decide to supplement with Vitamin E, take a look at the ingredients. It should say d alpha tocopherol NOT dl alpha tocopherol.
