Folic Acid May Reduce Blood Pressure

February 20, 2014


A short-term, high-dose supplementation period with Folic Acid (folate) may reduce blood pressure, and improve other cardiovascular measures.

Fifteen post-menopausal women received a daily dose of 15 mg of folate, for three weeks, and experienced an average drop in systolic and diastolic blood pressure of 4.5 and 5.3 mmHg, respectively.

The results of the placebo-controlled study are published in the European Journal of Clinical Nutrition.

Whether maintained in the long term, Folate’s cardiovascular and metabolic effect may contribute to primary cardiovascular prevention of postmenopausal women, reported the researchers from the Department of Obstetrics, Gynaecology and Paediatrics, Obstetrics and Gynaecology, at the Polyclinic of Modena, Italy.

The Italian researchers also reported a decrease in levels of homocysteine of 11.8 micromoles per litre for the folate group, compared to 8.7 micromoles per litre in the placebo group.

Studies have linked increased blood levels of the amino acid homocysteine to an increased risk of cardiovascular disease (CVD). It has been suggested that by lowering levels of homocysteine in the blood, people could cut the risk of cardiovascular disease.

The Modena-based scientists recruited 30 healthy post-menopausal women and randomly assigned

them to one of two groups. The first received the daily Folic Acid supplementation, while the other group received a placebo.

While the placebo was not found to modify any of the parameters, the women in the folate group experienced drops in their nocturnal systolic and diastolic blood pressure levels, “In a way that was significantly different from that observed during placebo”, said the researchers.

The high-dose folate supplement group also experienced significant reductions in homocysteine levels and in insulin resistance, whereby normal insulin amounts are inadequate to produce a normal insulin response from fat, muscle and liver cells.

Being a small, short-term study, the results need replication in larger, longer-term studies.

Folate is found in foods such as green leafy vegetables, chick peas and lentils. Folic acid – the synthetic, bioavailable form of folate – is obtained from grain products.
