Yes, it is completely normal for the iron in your Follihair tablets to turn your stool dark or black. When your body absorbs the iron it needs from the supplement, any unabsorbed iron passes through your digestive tract, causing this harmless color change. Please be reassured that this is a very common and safe side effect of iron supplements and is not a cause for concern. However, if you experience severe stomach pain, cramping, or other unusual symptoms, it is always best to consult your doctor.
