At the end of last month, a study was published in The Journal of the American Medical Association (JAMA) which indicates that vitamin E may be beneficial to slowing the effects of Alzheimer's in individual's with mild to moderate Alzheimer's over the course of two years.
Now, before you start popping vitamin E pills, keep in mind that the recommended daily dose is only about 22 IU. The study used 2000 IU of the vitamin which is a dose that is about 89 times greater than recommended the recommended daily dose. It even exceeds the higher tolerable dose. Why is this significant? The vitamin is fat-soluble and an overdose can lead to bleeding problems.
So, more work needs to be done, but this is very interesting.
