B Vitamins Might Lower Stroke Risk
But jury is still out on their value, experts note
People with heart disease who take high doses of B vitamins are somewhat less likely to suffer from stroke, especially if they're under 70, a new Canadian study suggests.
But other studies have come to opposite conclusions about whether vitamins really protect against cerebrovascular disease, noted Dr. Larry B. Goldstein, director of the Duke Stroke Center at Duke University, in Durham, N.C.
"We will need to carefully review this study in light of these other reports," said Goldstein. "There remains no evidence that general vitamin supplementation lowers risk of stroke or other cardiovascular events, and considerable evidence that it is ineffectual."
The Canadian researchers sought to determine whether high doses of three B vitamins could dampen the risk of stroke by lowering levels of an amino acid known as homocysteine.
Some research has linked high levels of the amino acid in the blood to a higher risk of stroke, although there's a debate over what this means.
National Stroke Association’s mission is to reduce the incidence and impact of stroke by developing compelling education and programs focused on prevention, treatment, rehabilitation and support for all impacted by stroke.
