Can you take a prenatal and a regular multivitamin at the same time?
Generally, no. A prenatal vitamin is already a complete multivitamin formulated with higher levels of the specific nutrients pregnancy requires, so adding a separate daily multivitamin on top mostly means doubling up on things like folic acid, iron, and fat-soluble vitamins A, D, and E rather than filling any real gap. If you have already been taking both, that is not typically an emergency, but it is worth simplifying down to one.
Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.
Why a prenatal already covers what a multivitamin does
A prenatal is built around the same foundation as a standard multivitamin, then adjusted for pregnancy's higher needs.† The American College of Obstetricians and Gynecologists outlines specific daily targets during pregnancy, including 600 micrograms of folic acid and 27 milligrams of iron, both of which a prenatal is designed to supply on its own (ACOG). Layering a second multivitamin on top does not add meaningful coverage. It mostly adds more of what you are already getting.
The two nutrients where doubling up actually matters
- Folic acid. The NIH Office of Dietary Supplements explains that folate has a tolerable upper intake level in supplement form because very high folic acid intake can mask the anemia caused by a vitamin B12 deficiency, delaying its diagnosis even while nerve-related effects continue (NIH Office of Dietary Supplements).
- Iron and fat-soluble vitamins. Combining two supplements that each contain iron, vitamin A, or vitamin D raises your total intake above what either product's label assumes, since labels are written for standalone use.
What the research says about staying within one formula
Mayo Clinic notes that the core difference between a prenatal and a general multivitamin comes down to folic acid and iron content, and that taking more of a nutrient than your body needs does not translate into extra benefit once your needs are already met (Mayo Clinic). The NIH's pregnancy-specific guidance reinforces this by setting nutrient recommendations as daily totals with defined upper limits, not as amounts to be assembled from multiple products (NIH Office of Dietary Supplements).
What to do if you have been taking both
- Stop the regular multivitamin and continue with your prenatal alone going forward.
- Mention it at your next appointment so your provider has the full picture, especially if you have been doubling up for more than a few weeks.
- Check your prenatal label against any other supplement you take (including gummy vitamins or a separate DHA) for overlapping ingredients, not just other multivitamins.
If you are looking for one formula that covers preconception through breastfeeding without needing to layer anything else, our prenatal with methylated folate and gentle iron is built as a standalone 22-nutrient formula for exactly that reason.† For guidance on other dosing questions, our guides on missed prenatal doses and prenatal timing cover related scenarios.

Frequently asked questions
Is it harmful to take a prenatal and a multivitamin on the same day?
It is not typically an emergency, but it usually means unnecessary overlap in folic acid, iron, and other nutrients rather than added benefit.†
Which one should I stop if I have been taking both?
Continue your prenatal and stop the separate multivitamin, since the prenatal is formulated for your current higher nutrient needs.
Can I take a prenatal along with a separate DHA or omega-3 supplement?
Check your prenatal label first. Many prenatals, including Total Prenatal, already include algae-sourced DHA, so an additional supplement may be redundant.†
Does taking both increase my risk of a birth defect?
Occasional overlap is not typically linked to that risk. The concern is more about masking a B12 deficiency or exceeding recommended iron and vitamin A intake over time.
What if my multivitamin doesn't have folic acid or iron in it?
Overlap risk is lower in that case, but it is still worth reviewing the full label with your provider rather than assuming it is fine.
Should I mention this to my OB even if I feel fine?
Yes. Your provider can review your full supplement list for anything worth adjusting, even without symptoms.
