Iron pills: Iron often causes black stool whether you take it with a multivitamin or not (taking vit c with iron enhances absorption. Quoting http://www.Nlm.Nih.Gov/medlineplus/ency/article/007478.Htm "black stools are normal when taking iron tablets. In fact, this is felt to be a sign that the tablets are working correctly.".
