Vitamin E slows Alzheimer's: study

High-dose vitamin E could help slow the progression of mild-to-moderate Alzheimer's disease, US research suggests.

Patients given a daily dose of 2000 IU of alpha tocopherol (vitamin E) over two years showed a 19% slower decline in their functional abilities compared to those given placebo, researchers reported.

The effect was equivalent to a six-month delay in disease progression, they wrote last week in the Journal of the American Medical Association.
