New research shows that people with Alzheimer’s disease who consume very high levels of vitamin E seem to live longer than those who do not. The findings stem from a 15-year study of the survival rates of 847 men and women already diagnosed with various stages of Alzheimer's disease.

Are high levels of Vitamin E safe? This has been a major research topic as some studies have suggested that high doses may also carry unwarranted health risks. The American Heart Association has stated that high amounts of vitamin E may be harmful for the average person and that taking 400 IU or more per day may increase the risk of death.

Vitamin E is a fat-soluble vitamin that acts as an antioxidant. Antioxidants help protect the body’s tissue from damage caused by unstable substances called free radicals. Free radicals can harm cells, tissues, and organs. They are believed to play a major role in certain conditions associated with aging.
