Vitamin B may lower stroke risk

Earlier studies on the effects of B vitamins on stroke were inconclusive.

In this new analysis of 14 high-quality studies excluded from previous reports, doctors found a link between B vitamins and lower chances of stroke. The studies included 54,913 older adults who took folic acid or B-complex vitamins, with follow-up periods from two to seven years. Overall, after taking B vitamins and lowering homocysteine levels—an inflammatory factor linked to stroke—participants were 7 percent less likely to have had a stroke of any kind.
