Chinese researchers just released a study that wanted to find out if the well-known vitamin folic acid would help to prevent strokes. The China Stroke Primary Prevention Trial was conducted from 2008 to 2013 in 32 communities in China on 20,702 adults with high blood pressure.

All participants were given the drug Enalapril (an ACE inhibitor commonly used to treat high blood pressure), but some were also given a folic acid supplement to see if the combination would be more effective in reducing stroke than Enalapril alone.

For four and a half years, participants received a daily pill either containing both 10 mg Enalapril and 0.8 mg folic acid or just 10 mg Enalapril. Compared with the Enalapril-only group, the Enalapril–folic acid group had a significant risk reduction in incidences of stroke and other cardiovascular conditions, including those that ended in death.

Researchers concluded that among adults with hypertension in China who had never had a stroke or heart attack, using folic acid along with blood pressure medication may further reduce risks.
