A member asked:
What causes light stool mixed with dark stool? i took an iron supplement yesterday. i was also recently in a car wreck but no internal bleeding was seen on ct scan?

Many iron containing supplements will turn the stools black. But keep it in mind that internal bleeding into the stomach can also cause tarry black stools although one can still see a reddish tinge of blood in the latter case. Moreover the GI bleeding will likely clear in a few days where as iron tablets will continue to color your stools black as long as you take them.
