Although early studies showed no overall benefit this may have been because they included people with kidney failure, who can be harmed by the adverse effects of cyanocobalamin, which is a form of vitamin B12.
Some of these studies showed that, while the number of strokes was reduced, there was an increase in myocardial infarctions.
