Health experts say simple supplement can cut stroke risk

Health experts in China are calling for what they say is long overdue: an effort to curb H-type hypertension by prescribing supplemental folic acid.

H-type hypertension is said to pose eight to 10 times the risk of a stroke due to an artery blockage to the brain compared with the non-H variety.

By reducing the incidence of the more dangerous type, 2.1 million cases of stroke could be averted annually, the experts say.
