Are upset stomach and constipation normal after starting to use iron supplements?

Yes: Iron frequently leads to upset stomach and constipation. Although iron can be dosed up to 3 x per day. Most patients cannot tolerate that often due to the abdominal pain that it causes. Sometimes adding vitamin C helps with iron absorption.

Dr Ali agreed

Yes: Constipation when using iron products is very common, but it also depends on diet, activity and fluid intake. All of these help to lessen symptoms of constipation overall. Having a high fiber diet also helps. If you have significant constipation when using iron- be sure to talk to your doctor to see if you have other options.
