Can vitamins turn poop black? I'd love responses.

My son's pediatrician said it's fine for him to take half of a childrens vitamin a day. I recently bought a new kind and today his poop is black. There is iron in them, 100% of the daily value, but he only takes half bc of his age (16 month). Do you think that may be what's causing it? I'm not sure how much iron would have to be ingested to cause this. My husband says to stop worrying and not to give him the vitamin and see what his poop looks like tomorrow. His Dr.'s office is closed and I don't want to call the on-call doctor if I'm worrying for nothing.

So, what do you think? Could it just be the vitamins, or should I worry that it's blood?

I should add, he's eating and acting totally fine.

  • It is probably the vitamins. Prenatal vitamins turn my poop a dark color sometimes. Sorry tmi.

  • Iron will turn BMs black. I would guess it is the vitamins.. Is the vitamin one for toddlers or children.. It may be too much for his system..

    Yes louise2, blood will also turn stool black. That is bleeding in the stomach or high in the intestines, lower GI bleed will still be red :)

    Pepto can also turn stool black.

  • I agree, iron can do that. Make sure your son is getting plenty of water so he doesn't get constipated from them, either.
