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.

Comprehensive and Trusted Prenatal Supplement
I’ve been using the THORNE Basic Prenatal while preparing for pregnancy and throughout early pregnancy, and I’m very impressed with its quality. It includes a well-researched form of folate, which is crucial for fetal development, along with 18 essential vitamins and minerals plus choline. I appreciate how this supplement supports my overall health as well as my baby’s development. The capsules are easy to take, and I have not experienced any side effects. This product gives me confidence in my prenatal nutrition and is definitely worth the investment for pregnant and nursing women. Highly recommended!

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

Good for breastmilk
This helped my breastmilk so much! However the taste and smell aren’t pleasant but anything for healthier vitamins
Katie Cardinal –
Worth it!
Worth it! I wish I had taken this prenatal for the first pregnancy. It’s got all of my labs coming back with excellent results. Even my provider was really surprised at my hemoglobin levels. Get this prenatal it’s the best.

Decent Product – Not For Everyone
Was taking this for a couple months before conceiving and then during the pregnancy before it was lost. I do think it is a good quality prenatal that gave me extra energy which was very much appreciated, but I did some more research and decided to go with a different option that fit my needs better- you can find that information below.I did notice some stomach upset at the beginning, but it went away after a few days. The main reason I ended up getting off of it, was due to wicked constipation. Could this have been due to the pregnancy itself? Possibly. I stopped taking this around the time I miscarried and switched to another option out there.The main reason I give it so many stars was because of the energy it gave me, but that’s ultimately why I decided to switch because there is conflicting information on the internet regarding the high dose of vitamin B in here. I’ll just stress that everyone needs to do their own research and it’s not the best choice for everyone.

Honestly. Surprisingly wonderful quality and great size!
Amazon カスタマー –
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.
