Which prenatal vitamin is the best?
The first time I found out I was pregnant, I did what so many of us do—I frantically grabbed a random prenatal off the shelf at Target and called it a day. Then I stuck with it throughout my entire pregnancy. I didn’t think much about ingredients, quality, or what my body actually needed. I just assumed all prenatal vitamins were pretty much the same. Turns out I was wrong.
But the second time around, I knew better. I wanted a prenatal that wasn’t just good enough but one that truly supported my body and my growing baby in the best way possible. So, I did what any research-loving, slightly obsessive mom-to-be would do—I created a table for myself of all the prenatal vitamin comparisons. I scoured ingredient lists, read reviews, and looked into the science behind what makes a prenatal actually effective.
I’m sharing a comparison of four popular prenatal vitamins I considered—Perelel vs. Olly vs. One A Day vs. Nature Made—so that you can easily compare them and decide which one is right for you.
Spoiler alert: Perelel comes out on top and I got you a 20% off subscription code: NMM20.
Perelel vs. Olly vs. One A Day vs. Nature Made
Criteria #1: Formula
The right prenatal vitamin gives your body what it needs to support a healthy pregnancy while also promoting your baby’s development. But not all prenatals cover the essentials. When choosing a prenatal vitamin, make sure it includes these key nutrients:
- Folate: supports growth and prevents neural tube defects
- Iron: essential for brain development, it also helps boost red blood cell production to carry oxygen, and works to prevents anemia in moms.
- DHA and EPA: these omega-3 fatty acids not only support your baby's brain development, but they may also increase a baby’s birth weight and lengthen the time they stay in the womb
- Choline: supports your baby's entire nervous system
- Vitamin D: supports bone development and the immune system
Perelel Prenatal
This is the only prenatal vitamin founded by an OB/GYN, so I trust that it's formulated with the best interests of both mama and baby. What sets Perelel apart is that instead of a one-size-fits-all approach, they offer a prenatal that actually changes with you. So, as you move through each trimester, your subscription seamlessly updates to match the nutrients you and your baby need at that stage (they have prenatals for each trimester—and even vitamins for conception, postpartum and early motherhood, etc.)I love that Perelel recognizes that each trimester is unique because the body—and baby—go through drastic changes trimester by trimester.
Here’s a breakdown of the nutrient formulation in each pack so you can see exactly what you’re getting at each stage:
| Nutrient | Perelel 1st Trimester Pack | Perelel 2nd Trimester Pack | Perelel 3rd Trimester Pack |
| Folate | 1525 mcg DFE | 700 mcg DFE | 700 mcg DFE |
| Iron | 15 mg | 15 mg | 15 mg |
| DHA | 250 mg | 250 mg | 250 mg |
| EPA | 100 mg | 100 mg | 100 mg |
| Choline | 120 mg | 120 mg | 120 mg |
| Vitamin D | 2,000 IU | 2,000 IU | 2,000 IU |

Criteria #3: Capsule size
Personally, I am terrible at swallowing large pills and would much rather take a bunch of smaller capsules than a massive capsule.
Perelel Prenatal
- Daily dose: 2 core prenatal capsules + 3 smaller capsules (5 in total) in each trimester pack
- The prenatal capsules are slimmer than the other prenatals tested, so even though you have to take two, I found them easier to get down. The other 3 capsules are small and easy to manage.
Olly Prenatal
- Daily dose: 2 gummies
- You chew these so size really is insignificant in this category!
One A Day Prenatal
- Daily dose: 1 softgel
- This is what I would consider a “horse-pill” – far too large for someone who has difficulty swallowing pills, or is suffering from nausea and doing whatever they can to keep it at bay in the first trimester, IMO
Nature Made Prenatal
- Daily dose: 1 softgel
- This is smaller than One A Day, but bigger than Perelel
Capsule Size Winner: Tied Perelel + Olly
