We explored whether stopping iron-containing prenatal multivitamins could alleviate nausea and vomiting in pregnant women. In a study involving 97 women seeking help for severe nausea, we discovered that two-thirds reported an improvement after switching to alternatives like folic acid or children's vitamins.
This significant finding, backed by both qualitative and quantitative measures, shows that avoiding iron supplements in early pregnancy may be beneficial for many women struggling with nausea.

We aimed to understand how prenatal multivitamins, particularly those containing low doses of iron, affect women with existing gastrointestinal (GI) issues during pregnancy. By comparing women with and without GI conditions, we found that those with GI issues did not have more side effects or lower adherence to taking multivitamins.
In fact, they may have experienced less severe nausea and vomiting compared to women without GI conditions. This suggests that small, low-dose iron prenatal vitamins should still be considered a viable option for pregnant women with such pre-existing conditions.

Prenatal vitamins and nausea insights
We examined how two different prenatal multivitamins impacted nausea in pregnant women. Our study involved 135 participants who tried both PregVit, which contains less iron, and Materna, with a higher iron level.
We found that PregVit led to lower rates of constipation, making it more tolerable for users. Interestingly, with Materna, higher nausea and vomiting were linked to lower compliance. In contrast, these issues didn’t affect how well women tolerated PregVit.

Gentle on nausea
31 people found this helpful
These vitamins are brilliant! My nails are long, my hair is shiny, and I feel much better on them (not as fatigued as before). I experience some nausea now and then during this second pregnancy, but these vitamins have never caused any issues for me. I took them on a mostly empty stomach and felt fine. They are easy to swallow, with no after-taste. My midwife also recommends these vitamins. In my first pregnancy, I suffered debilitating migraines from prescribed prenatals, but I discovered that my migraines coincided with those vitamins. This organic, gentle vitamin has been fantastic!

Superb vitamins. They did not cause any nausea. During my pregnancy, they raised my haemoglobin without the need for iron supplements.

It's seriously that amazing! This prenatal duo set is exceptionally good! I researched the recommended daily amounts by the American College of Obstetricians and Gynecologists for 2019: folic acid: 600mcg, iron: 27mg, calcium: 1,000mg, vitamin D: 600 IU, vitamin A: 770 mcg, vitamin C: 85mg, vitamin B6: 1.9mg, vitamin B12: 2.6mcg. They consider Omega-3s with DHA a bonus! The duo combination exceeds expectations! Best of all, I take it on an empty stomach and have absolutely no nausea! Yes! Not even a tummy ache. Plus, the fish tablet has no fishy taste or burps! Seriously, I would recommend this brand to anyone trying to conceive!

Caused intense nausea
3 people found this helpful
I had seen these recommended and decided to try them. They were my third brand of prenatals. I experienced no issues with previous vitamins, but after taking my first Rainbow Light yesterday with insufficient food, intense nausea hit me quickly. I couldn't stomach it, and I need to consume a good meal to avoid nausea with these, which is a concern during pregnancy.

Empty stomach issues
This vitamin complex may be effective, but it's advisable not to take it in the morning on an empty stomach, as it can cause nausea and vomiting. The tablets are large and have a strong herbal taste which exacerbates nausea during pregnancy.
