(CBSNews.com) - Taking vitamin B supplements might help to reduce your risk of a stroke, according to new evidence published today in the journal Neurology.

The study by researchers at Zhengzhou University in China reviewed 14 clinical trials and found that Vitamin B lowered the risk of stroke overall by seven percent.

However, taking the supplements did not appear to affect the severity of the strokes or the risk of death from a stroke, according to the review.

"Previous studies have conflicting findings regarding the use of vitamin B supplements and stroke or heart attack," the author, Xu Yuming, said. "Some studies have even suggested that the supplements may increase the risk of these events."

The results were published in the online issue ofNeurology, the medical journal of the American Academy of Neurology.
