From the expert

Homocysteine is an amino acid used by the body to make protein and build and maintain tissue. Excessive homocysteine levels in the blood may increase the risk of stroke, certain types of heart disease and disease of the blood vessels of the arms, legs and feet (peripheral artery disease). Although a raised homocysteine is a risk factor for cardiovascular disease, it is not known whether it is causative or a result of the condition.

As vitamins B6, B12 and folate are required to break down homocysteine in the body, and an increased homocysteine level may be a sign of deficiency in these vitamins. Homocysteine can be lowered through increased intake of vitamin B12 and folic acid.
