Can taking an iron supplement turn my poo black?
Hi Alex, just a quick question, I have just started taking an iron supplement, can this turn my poo black? or is it from something else that i have been eating?. It has been black for about 5 days now. Thanks Danielle

Answer:
Hi Danielle,
Iron supplements can cause constipation and it does turn poo black!
Best wishes,
Alex
