It is completely normal and very common for your stool to turn dark black while taking Autrin, which is an iron supplement. When your body absorbs the iron it needs, the unabsorbed portion is naturally excreted, causing this harmless color change. However, to be safe, if you experience other symptoms like severe stomach pain, dizziness, weakness, or if your stool becomes sticky and tarry, please contact your doctor.

Is it normal for my stool to turn dark black after taking Autrin tablets for low blood, or could this be a sign of bleeding in my stomach?
