If you are like 1/3 of American Adults that have high blood pressure you may want to check your folate (folic acid) levels. Folate is the naturally occurring B vitamin found in many green leafy vegetables but added to many foods in the form of folic acid because of its well-documented role in maintaining health especially for pregnant women. Folic acid's cardio protective qualities have been documented for decades according- see the link to Harvard Medical School's article on the same topic below.
A robust study in China demonstrated better protection from stroke using a combination of folic acid and enalapril (a well studied cheap generic antihypertensive medication) for patients with already low levels of folic acid and hypertension.
A general practitioner or primary care physician may recommend routine bloodwork which will quickly uncover certain types of anemia and vitamin deficiencies like a folate deficiency. The important thing is that you speak openly with your healthcare professional and follow their guidelines- just be sure that you are being heard too.
