The Best Prenatal Vitamin: A Review of Honest Company Prenatal Vitamins

I love The Honest Company Prenatal Vitamins and felt it needed its own review. I switched to these prenatal vitamins shortly after learning what to look for in prenatal vitamins.

Honest Company Prenatal Once Daily Review


A once daily prenatal vitamin is much more convenient than taking multiple vitamins throughout the day. Plus, the Honest Company prenatal vitamin doesn’t have a bad odor, is easy to swallow, and easy to digest. What else makes these the best prenatal vitamins?

Honest Co’s Prenatals have L-Methylfolate

Folate comes in 3 basic forms in prenatal vitamins. Folic Acid is converted into folate by the liver. Folate is then converted into the active form of L-methylfolate in the body. Most prenatal vitamins contain folic acid. Some contain folate. And very few contain L-methylfolate. Honest Company’s prenatal vitamins are one of the few that contains methylfolate and this was a huge part of why I selected them as the best prenatal vitamins.

The Right Iron

Iron is often the ingredient that causes stomach complaints such as nausea, which is why some prenatal vitamins don’t contain any. However iron is essential in pregnancy for you and your baby and this vitamin contains 27mg, which is plenty. Interestingly, the form of iron in Honest Co’s prenatal vitamin is ferrous bisglycinate.

Most prenatal vitamins have ferrous sulfate. So I did a quick review of the research to check the efficacy of ferrous bisglycinate. What I found is that not only is this form of iron as effective as ferrous sulfate, but it is also better tolerated. People did not experience the GI complaints, such as nausea. So another win!

Enough Iodine for Hypothyroidism

Iodine is essential for thyroid function, and I have hypothyroidism so I wanted to make sure I was getting enough iodine. Honest Company’s prenatal vitamin contains 200 mcg of iodine. The American Thyroid Association recommends women take at least 150mcg of iodine and the recommended daily intake is 220-250mcg, so this vitamin has more than most others out there.

Not too much Vitamin A

The vitamin A in the Honest Company Prenatal vitamin is in the form of beta-carotene. You may remember from my previous article that an excessive intake of animal-based vitamin A has been associated with birth defects. However, vitamin A in the form of beta-carotene has not been found to increase the risk of birth defects.

Plenty of Vitamin D3

Vitamin D is in the form of cholecalciferol, which is D3. Honest Co.’s prenatal vitamin has 1400 units of D3, which is more than the recommended daily intake of vitamin D3 (but still safe). D3 is more readily absorbed by the body and therefore more effective. A previous prenatal vitamin I was taking had D2, so finding this vitamin with D3 was important to me.


No vitamin has it all. Honest Company’s prenatal vitamin only contains 200mg of calcium. If you remember from my previous post, the recommended daily intake of calcium is 1000mg.

Additionally, it only contains 30mg of choline. And it does not contain any DHA.


Overall, it meets the minimum requirements for most of the necessary nutrients and has many ingredients that other vitamins lack. While no prenatal vitamin contains everything you need, the Honest Company Prenatal Vitamin is the best prenatal vitamin on the market. I decided I could take a prenatal choline supplement, a calcium supplement as well as a prenatal DHA supplement. Also, while it’s difficult to call any of these organic prenatal vitamins, Honest Company’s prenatals do contain an organic fruit and vegetable blend. These vitamins come in at $0.67 per day.
