Should you continue to take Iron supplements if it turns your stool black? - black stool more condition_symptoms

My friend told me she began to iron tablets in the morning before work, and I noticed that your chair has become black. Is this a problem? If you stop taking the tablets, she feels better and stronger because of them, but the only concern is the color of his chair. It is the color of feces is a problem?
