Brief Answer:
yes Iron pills cause black stool

Detailed Answer:
Hello XXXX,

Yes stool get black colored on taking oral iron tablets. It will again come to normal color within 2-3 days of discontinuation.
You are not suffering from any liver disease or gastric ulcers as upper gastrointestinal bleed can also lead to black tarry stool called as malena.
If your stool discoloration is linked to iron intake then nothing to worry about.

Hope you found the answer helpful.
Wishing you good health
