Antioxidant supplements may not help ward off dementia, a new study suggests. Although previous research had suggested a possible link between the two, this latest study is one of the largest studies to investigate whether antioxidants could help ward off dementia, and found no such link. Researchers analyzed information from more than 7,500 U.S. men ages 60 and older who were randomly assigned to take a daily vitamin E supplement, a daily selenium supplement, both supplements or a placebo. Both vitamin E and the mineral selenium are antioxidants, which means they may prevent some types of damage in cells. The men took the supplements for about five years, on average, and during that time, the researchers followed up with them to determine which men developed dementia. After that, a subset of about 3,700 men agreed to be followed for an additional six years while they were not taking the supplements.
