Is it normal to be constipated from prenatal vitamins?

Yes: Yes, constipation is usually due to the iron content in the prenatal vitamins. Some prenatal vitamins will contain a stool softener to help with the constipation. Remember also that pregnancy itself will at times lead to constipation due to the hormone Progesterone which slows the transit time through the bowels. Increased fluids and high fiber foods will help.

Yes: Depends on the iron content. Try a low iron variety.
