Vitamin B Seems To Reduce The Risk Of Stroke, But Not The Severity, Study Finds

Chinese researchers who analyzed 14 randomized clinical trials involving nearly 55,000 patients found that vitamin B supplements lowered the risk of stroke by seven percent. The researchers noted, however, that taking vitamin B did not seem to reduce the severity of stokes or the risk of death from a stroke. They also said vitamin B’s ability to reduce stroke risk may be influenced by several other factors: the body's absorption rate, the amount of folic acid or vitamin B12 concentration in the blood, and whether a person has kidney disease or high blood pressure. Folic acid, often found in fortified cereals, actually reduced the effect of vitamin B.
