Does vitamin E supplementation improve Crohn's symptoms?

Vitamin E from Wikipedia

Vitamin E from CyberLipid Center
"The term "vitamin E" should be used for all tocopherol, tocotrienol and tocomonoenol derivatives exhibiting the biological activity of d-a-tocopherol. The term "tocopherol" should be used for all methyl tocols. Since tocotrienols have some vitamin E activity, "tocopherol" is not synonymous with "vitamin E"."

"Advanced Plan: Supplements" from Mercola.com
"Keep in mind that your body can easily distinguish between natural and synthetic vitamins, and natural vitamin E is between two and three times as bioactive as the same amount of synthetic vitamin E. Natural vitamin E is always listed as the "d-" form (d-alpha-tocopherol, d-beta-tocopherol, etc.). Synthetic vitamin E is listed as " dl-" forms.

But your optimal source for vitamin E is from your food. A 2002 study suggested that if you consume plenty of vegetables (about one pound of vegetables for every 50 pounds of body weight), the antioxidants in the vegetables may provide as much, or more, protection as vitamin E supplements."
