Specializes in Gastroenterology

It's possible.: As long as your stools are not solid black or bloody, it is possible that it is related to the grape juice. You should stop the grape juice for one week, and then resume taking it. If your stools return to normal initially but then return to the odd color, you have your answer. Good luck.
