Comprehensive and Gentle Prenatal Support
Thorne Basic Prenatal is my go-to prenatal supplement. It provides all the essential nutrients I need during pregnancy in a gentle, high-quality formula. I feel confident that I’m supporting my baby’s development with something safe and effective. The capsules are easy to take, and I appreciate Thorne’s commitment to purity. Highly recommend for expecting moms!

Smells
I wanted to like this vitamin but I’ve taken them two days in a row and vomited shortly after. I can’t bear the smell of the vitamins even before the bottle gets opened. I’m disappointed as I spent money on these vitamins and can’t even finish them.Update: I’m adjusting my rating for the excellent customer service and quick response. I am willing to try different products from their line when I am no longer pregnant.5/26/25 postpartum update: I decided to give the prenatal vitamin another chance because I really like the ingredients and that this brand does 3rd party testing. I’m able to better tolerate the smell. I do notice my milk supply increases when I take the vitamin and my milk is lower in supply when I forget to take it, not sure if it’s a coincidence or if it actually helps boost supply. I am happy with the vitamin and will continue to use Thorne!

Best ever prenatal
I’ve been using Thorne Basic Prenatal and you can truly tell the quality. I love that it includes well-researched folate (not just standard folic acid), plus choline and 18 essential vitamins and minerals to support pregnancy and breastfeeding. It’s also gluten-, dairy-, and soy-free, which gives me extra peace of mind.I definitely recommend it if you’re looking for a clean, research-backed prenatal with highly absorbable ingredients.

High-quality prenatal vitamins that really make a difference
I’ve been taking Thorne Prenatal Vitamins for several months now, and I’m really happy with them. These pills are easy on my stomach (no nausea or discomfort), and I feel confident knowing they use clean, well-absorbed ingredients without unnecessary fillers. No nasty taste or acid reflux with these. I still take them postpartum

Good quality but make me sick
The prenatal vitamins have a very good ingredient list, but unfortunately they made me feel very nauseous. It might be individual sensitivity, or possibly because the doses of the vitamins are quite high

Prenatal
I got these for the ingredients. I did get sick at first taking them in the morning on an empty stomach. I changed taking them on a full stomach before bed and haven’t had issues since. They do have an odd metallic smell to them. Overall great product if your stomach can tolerate it.

This regulated my cycle!
I started taking the Thorne Prenatal to help regulate my cycle. I stopped taking birth control about a year ago, and about 7 months later my cycles completely stopped and I went 3 months without a period. After starting this prenatal, my cycles immediately went back to normal. My skin is also the softest and smoothest it’s ever been, and I typically struggle with hormonal acne. The only downside is the flavor, but I take it with orange juice and it helps mask it. Will update if needed!

Nausea
Really love this brand. Love that it is 3rd party tested and clean ingredients. Sadly, every time I take it. I get super nauseous.

The product is fine but don’t bother ordering from iherb. They will cancel your order and only inform you of this 4-5 days later. It’s better to order from another vendor.
