While vitamin E's antioxidant properties suggest that it may provide potential health benefits, there are conflicting findings about the medicinal value of vitamin E supplementation beyond the recommended daily allowance. Scientists have found, for example, that the nutrient has potential to benefit the immune system and prevent various diseases, but taking high doses also increase risks for bleeding problems.
Now, in new work that has yielded information adding weight to the positive side of vitamin E's balance sheet, researchers have discovered how a derivative of vitamin E can kill cancer cells and have used the information to make the derivative better (Shiau CW et al. J Biol Chem. 2006;281:11819-11825).
