Homocysteine may be an important risk factor for heart disease and stroke

    There's growing evidence that homocysteine may be an important risk factor for heart disease and stroke.

    People with elevated homocysteine levels seem to be twice as likely to die of heart disease. It might turn out to be as significant as high cholesterol...smoking...or hypertension.

    Homocysteine is an amino acid...it's a by-product of protein metabolism. High serum concentrations damage the arterial wall and lead to atherosclerosis. It may also increase the risk of clotting.
