The single daily tablet contained about 10 mg of enalapril and 0.8 mg of folic acid. Participants were observed for about 4.5 years. 

Researchers found people who were given enalapril  and folic acid pill were LESS likely to suffer a first stroke, compared with the group that only took enalapril.

  • 282 (2.7%) patients who took enalapril and folic acid had a first stroke
  • Compared to 355 (3.4%) patients who were given only enalapril
  • Folic acid & enalapril combination helped reduce the risk of stroke by 21%
