E Gets an 'A' at Lowering Risk of Diabetes Complications
The researchers found that in both diabetics and nondiabetics, high doses of vitamin E greatly decreased the release of damaging substances and chemicals and reduced the amount of the repair cells that stick to blood vessel walls.
And although some researchers worry that high-dose vitamin E supplements may be harmful, the researchers found no evidence of side effects throughout the three-month study.
The current study dovetails neatly with one reported by George L. King, MD, and colleagues at Harvard Medical School, which found that high-dose E is effective at preventing and may even help to reverse diabetes complications in small blood vessels within the eyes and kidneys in people with type 1 diabetes.
"The assumption here is that its only effect is as an antioxidant, but there's quite a bit of data, which we and others have shown, that vitamin E also has effects on other systems," King says, adding that what is clearly needed is a large, lengthy study of high-dose vitamin E to test this controversy.
