What is Homocysteine?

Homocysteine is an amino acid found in the blood. Elevated levels are associated with increased risk of heart and vascular disease. Unfortunately accurate measurement of homocysteine levels is not yet readily available for all cardiac patients. Diets high in folic acids and B vitamins lower homocysteine levels, but no controlled studies have directly shown that dietary supplements lower the risk of heart disease. With that caveat, a balanced diet and a multivitamin with folic acid and B vitamins may be beneficial.
