When should you start and stop taking a prenatal vitamin?

Most experts recommend starting a prenatal at least one month before you begin trying to conceive, since folic acid needs time to build up before it can offer its full protective benefit. On the other end, we recommend switching to a postnatal like Total Postnatal + DHA after birth to support postpartum recovery and lactation goals.  

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

Starting: earlier is better, but any start helps

The American College of Obstetricians and Gynecologists recommends taking a daily prenatal vitamin at least one month before pregnancy and continuing through the first 12 weeks, specifically to make sure you are getting enough folic acid during the earliest, most critical window of fetal development (ACOG). If you did not start that early, beginning as soon as you find out you are pregnant, or as soon as you start trying, still provides meaningful benefit going forward.†

Stopping: less about a date, more about your stage

Unlike the start of pregnancy, there is no universal cutoff for when to stop. Jessica Gering, APRN-NP, an OB-GYN nurse practitioner, advises that women should "continue taking your prenatal vitamin at least while you're breastfeeding" (Nebraska Medicine). We formulated Total Postnatal + DHA to meet the specific needs of postpartum women and replenish the nutrient stores used during pregnancy and delivery.

• Breastfeeding: Continue your prenatal, or transition to a postnatal formula, for as long as you are breastfeeding.
• Not breastfeeding: Many healthcare providers recommend continuing supplementation for 6 months after birth to help rebuild iron, folate, and other nutrient stores.†
• Planning another pregnancy soon: Staying on a prenatal or postnatal formula between pregnancies helps maintain folate levels for the next conception window.

Why the "postnatal" version exists at all

A postnatal formula is built around the specific demands of recovery and lactation rather than fetal development, which is why the nutrient profile shifts slightly even though many of the core ingredients overlap.† Total Postnatal, designed to support breastfeeding and recovery, is formulated with methylated folate, vegan algae-sourced DHA, and iron to support postpartum replenishment specifically, rather than simply continuing your pregnancy-stage prenatal indefinitely.

Throughout pregnancy itself, our prenatal with methylated folate and gentle iron is designed to be taken consistently from preconception through birth.† For the breastfeeding-specific question, see our guide on whether you need to keep taking a prenatal while breastfeeding, and for the preconception side, see our guide on starting a prenatal before you're actively trying to conceive.

"I'd say to continue taking your prenatal vitamin at least while you're breastfeeding. It certainly doesn't hurt to continue taking it."

Frequently asked questions

How early should I start taking a prenatal vitamin?

Ideally at least one month before you begin trying to conceive, though starting as soon as you learn you are pregnant still provides real benefit.

Is there a specific date I should stop taking my prenatal after birth?

No universal date exists. Many providers recommend continuing through breastfeeding and for a period afterward to rebuild nutrient stores.

Do I need to switch to a postnatal vitamin, or can I keep taking my prenatal?

Either can work, but a postnatal formula is specifically built around postpartum recovery and lactation needs, which may fit your stage more precisely.†

What if I am not breastfeeding? Do I still need to keep taking a prenatal?

Many providers still recommend continuing supplementation for a period after birth to help replenish nutrient stores depleted during pregnancy and delivery.

Should I stay on a prenatal between pregnancies if I plan to conceive again soon?

Yes, many providers recommend this to maintain folate levels heading into the next conception window.

What happens if I did not start my prenatal a month early?

Starting as soon as you find out you are pregnant, or as soon as you begin trying, still provides meaningful benefit going forward.
