Can I Take iron with prenatal vitamins?

SUMMARY:

Taking a separate iron supplement together with a prenatal vitamin that already contains iron can duplicate iron dosing and increase gastrointestinal side effects; check the total elemental iron amount. In some pregnancies extra iron is prescribed by a clinician, so consult your healthcare provider before combining supplements.

ADDITIONAL NOTES:

Many prenatal vitamins include iron (often 27–60 mg elemental iron); adding an additional iron supplement increases total iron intake and commonly raises risk of nausea, constipation, abdominal discomfort, and dark stools. Rarely, excess iron may be harmful in people with iron-overload disorders (eg, hemochromatosis). Review product labels for elemental iron, follow prescriber dosing, and consider timing (iron absorption can be reduced by calcium, antacids, and some foods; vitamin C can enhance absorption) — discuss with your clinician or pharmacist if unsure.
