One of the most important steps you can take during pregnancy to ensure you have a healthy baby is also one of the simplest: popping a prenatal vitamin every day. While a prenatal vitamin can't replace a healthy diet full of the best foods for pregnancy, a supplement helps you fill in any gaps, says Nicole Rankins, M.D., an OB/GYN and site director of the OB Hospitalist Group in Norfolk, Virginia. After all, it's tough to meet the nutrient demands of pregnancy through food alone — especially when you're dealing with food aversions or morning sickness.
And no, a standard multivitamin won't do the trick — I had the same question during my first pregnancy. Prenatal vitamins are specially formulated for pregnancy. "If comparing them side by side, you would notice higher amounts of many nutrients in a prenatal vitamin compared to the standard multivitamin for women," says Olivia Small, R.D.N., a prenatal dietitian and certified lactation counselor at The Ohio State University Wexner Medical Center. For instance, prenatal vitamins contain higher levels of iron and folic acid than a standard multivitamin.
How we chose the best prenatal vitamins
First and foremost, your prenatal vitamin needs to provide the right nutrients (and the right amount of them) to support your body throughout your pregnancy. This is why all the prenatal vitamins on this list meet the prenatal nutrition guidelines from the American Congress of Obstetricians and Gynecologists (ACOG). But to learn about the benefits each of these nutrients provide to pregnant women, we spoke to Small and Dr. Rankins, as well as Jill Purdie, M.D., medical director and OB/GYN at Northside Women's Specialists and Christine Greves, M.D., a board-certified OB/GYN at the Winnie Palmer Hospital for Women and Babies in Orlando, G. Thomas Ruiz, M.D., a board-certified OB/GYN and lead OB/GYN at MemorialCare Orange Coast Medical Center in Fountain Valley, California, Alexa Sassin, M.D., a board-certified OB/GYN and assistant professor of obstetrics and gynecology at Baylor College of Medicine and Meleen Chuang, M.D., a board-certified OB/GYN and chief of service in Obstetrics and Gynecology at NYU Langone Hospital Brooklyn. (You can learn more about the recommended ingredients and their benefits below.)
Additionally, because prenatal vitamins are supplements and not well regulated, Small suggests taking vitamins that are certified by the National Sanitation Foundation (NSF) and United States Pharmacopeia (USP), which ensures they were tested for quality and safety. All of our recommendations for prenatal vitamins have an independent certification to back up their claims.
Of course, if a prenatal vitamin tastes bad or causes an upset stomach, you may be less likely to take it. And what good would that do? To get an idea of which prenatal vitamins moms can actually tolerate, we spoke to seven mothers on the What to Expect staff, who have altogether tested all of these prenatal vitamins during their combined 13 pregnancies. We also utilized the results and feedback of the 2023 Mom Must-Have Awards, in which more than 375 moms from our user community voted on the prenatal vitamin they’d recommend most. In both instances, we considered their feedback on taste, smell, ease of swallowing and side effects, eliminating any prenatal vitamins that received poor reviews.
