A study published by the American Journal of Cardiology last month finds that cardiovascular patients with high homocysteine levels (above 15µmol/l) treated with B vitamins cut their risk of death by a quarter over ten years.
Among those not given B vitamins 32% had died, compared to only 4% of those given high dose vitamins. Homocysteine is now a proven marker for cardiovascular disease risk. For example, a recent meta-analysis concludes “each increase of 5 μmol/L in homocysteine levels increases the risk of CHD events by approximately 20%, independently of traditional CHD risk factors“. Lowering homocysteine levels with B vitamins has also been shown to reduce stroke risk.
