While media attacks on the use of vitamins mount, research continues to show the benefits of supplementation. A recent study showed that 2,000 IU of vitamin E a day resulted in a clinically meaningful delay in the progression of Alzheimer's disease. The progression of the disease was slowed by 6.2 months over a period of 2.3 years.
The authors of this study noted that there was a decrease in all cause mortality among the group taking the vitamin E in spite of other studies that have suggested that vitamin E increases all cause mortality.
The dose of vitamin E was very high in this study. A more sensible experiment would probably have been to use smaller amounts of a wide variety of antioxidants since these nutrients work synergistically.
