A member asked:

Today ive started taken 2x iron tablets as prescribed for a deficiency. my poop has turned a green/grey colour. does this mean im not absorbing it?

Yes and No: It means some of what you are taking is not being absorbed. Almost certainly you are absorbing some. Take vitamin C (500 mg) before you take the iron to increase the absorption.

I was prescribed 325mg ferrous sulfate for an iron deficiency six months ago. Though my iron levels are now normal, I woke up very tired, thought it may be due to iron, and took one pill. Will this harm me? I took it 12 hours ago and feel okay?

What does it mean when you have a gray stool? I take 325mg daily of ferrous sulfate (iron) so the stool is usually black. It has been gray for about a week.
Would iron cause dark gray stool?
