High folic acid (folate) supplementation lowers women's blood pressure.
Data from two large studies involving 62,260 women between the ages of 43 and 70 and 93,043 women between the ages of 26-46 revealed important information on the nutrient folic acid (folate).
When women consumed 800mcg per day or more of folate, they were significantly less likely to develop hypertension, than women taking lesser amounts. This news was just reported at the annual conference of the American Heart Association. According to the research scientists, it is very hard to get 800 mcg of folate daily from diet alone, taking supplemental folic acid is necessary.
