Does anyone find taking vitamin D capsules turn their stool black?
Posted , 16 users are following.
Ive been taking Vitamin D capsules for a few months and noticed my stools are darker , sometimes even black. I've heard of this when you take iron supplements but not sure about VD. It has me concerned because black stool prior to this resulted in 2 colon polyps being removed but I'm not due for another colonoscopy for 2 years. I wondered if anyone else has experienced black stool while taking VD. I take 2000 IUs a day?

Yes carol7212 I too seem to find that happening. I just started VD3 1000 about 1 week. I'm glad to know someone else is having this as well. Louzell

I took a 60000 IU capsule last night and my stool is dark today.
I got paranoid as I have a history of ulcerative colitis.
So its a relief to know that this happens and I'm not necessarily bleeding.

Hi bh66
Yes I can see why you might be paranoid since you've had a history with ulcerative colitis.
Ever since I've taken Vitamin D supplement I've had black stool consistently. It seems to go hand in hand so I wouldn't worry too much that it's bleeding.
You can consult a doctor if it bothers you a lot but black stool is a given when taking Vitamin D.

Vitamin tablets have that effect on stools. Too much sugar causes diabetes. Fats could it harder to get stools out of the system.

I'm so glad I came on this page as I was getting really concerned about the colour of my poo ! Dark grey/black. The only thing I've taken different is vit D for about 2 months. Such a relief to know it's not just me.

Hi L,
I started noticing that my stools appeared dark brown/ black about a month after starting the Vitamin D.
Since not long after that I had asked my doctor about it and he said the vitamin could definitely do that so needless to say I was quite relieved.
You should always get things checked out however just to be sure.. but I'm glad you've found relief knowing it's very possible the Vitamin D is the cause of your differing stool color.
It was for me lol.

Many thanks for your response, Carol. I feel very relieved that other people have the same experience with vitamin d. I shall be doing a bowel cancer test next month, just to be on the safe side.

Hi Nikita,
Glad you feel better seeing that other people have experienced dark color poo while taking Vitamin D.
As for the look of chopped up grass I can't say as I personally have, but I have a friend who once mentioned she had very dark stool that looked like shredded grass. Her doctor didn't really know but said it cud have been caused by anything green she had eaten in a few days prior.

It's definitely reassuring!
People always tend to think the worse and worry themselves sick.
I have a few friends who are currently taking Vitamin D and their stools are now black .
