A number of the B vitamins, B-3 (niacin), B-6, B-9 (folic acid) and B-12, have been associated over the years with improved heart health. These vitamins may become even more important as the role of homocysteine is determined.
Homocysteine is a natural amino acid that is found in your body. Higher levels of homocysteine in the blood are associated with an increased risk of heart disease, stroke and peripheral vascular disease. The higher your homocysteine blood level, the greater your risk. Several vitamins, particularly B-6, B-12 and folic acid, can reduce blood levels of homocysteine. What is not currently known, however, is whether taking these vitamins reduces your risk of heart disease.
