As vitamins B6, B12, and folate are required to break down homocysteine in the body, increased homocysteine levels may be a sign of deficiency in these vitamins. 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.
You can lower your homocysteine levels through increased vitamin B12 and folic acid intake. Always consult your doctor before making significant changes to your diet.
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).
