Vitamin B Supplements Fail to Prevent Dementia

More than 8000 patients with a history of recent stroke were randomized to either a placebo or a daily dose of B vitamins (folic acid, B6 and B12). After an average of 3.4 years of follow-up, both treatment groups had the same risks for major vascular events. The results of this 20 country study do not support the use of B vitamins to prevent recurrent stroke.

PositiveTip: Do not count on supplements to prevent disease. Choose a wholesome diet rich in whole-grains, vegetables and fruit for the best outcomes.
