Combination of Vitamin E Best For Decreasing Cognitive Decline
Taking a supplement containing a combination of different forms of vitamin E may help protect against Alzheimer's according to a recent study conducted in Sweden.
The study was published in the June 2010 issue of the Journal of Alzheimer's Disease.
Researchers at the Aging Research Center in Stockholm recruited 232 participants over 80 years of age for the study.
At the beginning of the study none of the participants had dementia. Over the course of a 6 year follow-up, 57 (25%) of the participants were diagnosed with Alzheimer's.
Using blood samples, the researchers were able to determine that participants with higher levels of all 8 forms of vitamin E had a significantly reduced risk of developing dementia.
A number of studies have previously found a link between vitamin E intake and reductions in dementia risk but this study shows that combining various forms of the vitamin may increase its protective effect.
The high level of antioxidants in vitamin E is likely responsible for its various health benefits which range from helping patients recover more quickly following stroke to boosting the immune system.
These benefits, particularly in terms of immune health, seem to be especially strong among mature adults because the activity of immune cells naturally declines with age, resulting in a weaker immune system.
Vitamin E can be found in a number of foods, but only in small quantities. For this reason, many people do not get enough vitamin E daily and could benefit from a supplement. The best supplements have vitamin E in the natural form (the synthetic version is about half as effective) and liquid supplements are usually best.
