High levels of amino acid homocysteine are thought to increase the risk of heart disease. Because folate/folic acid helps to decompose homocysteine, low folate/folic acid can lead to high homocysteine levels, also known as hyperhomocysteinemia.
Folate/Folic Acid supplements can help reduce homocysteine levels and may reduce the risk of heart disease.
For example, a review of 30 studies involving more than 80000 participants showed that folate/folic acid supplementation reduced the overall risk of heart disease by 4% and stroke by 10%.
More importantly, the use of folate/folic acid supplements and antihypertensive drugs can significantly reduce hypertension compared to the use of antihypertensive drugs alone. Folate/Folic Acid supplements can also improve vascular function in patients with heart disease.

We recommend you to supplement better folate:
Magnafolate® L Methylfolate(active folate)—maximizes the supplementation delivering a "finished" folate the body can immediately use without any kind of metabolization.
It can better supplement the folate that the body lacks.
