Low levels of vitamin B12 are associated with an increased risk of cardiovascular disease, but the scientific review found no consistent evidence that B12 supplements alone prevent heart attacks or cardiac death. B-vitamin combinations reduced stroke rates by about 10% overall, and by 30–35% in regions where foods are not fortified with folic acid. However, this benefit cannot be attributed to B12 alone. The review recommends treating confirmed deficiencies for the benefits to blood and nerve health, while noting that more research is needed to determine who might benefit from supplements for cardiovascular prevention.
