• together with B6 and B12, 1000 mcg of folic acid per day keep homocysteine levels (an independent factor for heart disease) in the safe range Lancet 1995

• There was good research being conducted on homocysteine levels and cardiovascular/heart disease until the Pharmaceutical Industry created cholesterol lowering dugs and all the research money went there to support the industry – cholesterol lowering drugs can be patented and big money can be made – B6, B12 and folic acid cannot be patented so no big money to be made from research on how they lower homocysteine and support cardiovascular/heart health

• Insist that your doctor authorize tests to measure and monitor your homocysteine
