Prenatal Vitamins and Nausea: What I Learned Testing moode on Myself While Pregnant
When I was pregnant and taking a competitor prenatal, I had to mentally psych myself up every single time. The smell alone was enough. I would open the bottle, gag, force the capsules down, and then spend the next 30 minutes wondering if they were going to stay there. This is not a small thing when you are already navigating first trimester nausea. It is genuinely miserable.
It was one of the main reasons I formulated moode. I tested The Prenatal on myself throughout my pregnancy, and then offered it to pregnant friends for feedback before we launched. We did not stop until we had something that women could consistently take without dreading it. Because a prenatal you cannot consistently take is not doing its job.
But even with a better formula, there were days when nausea made taking anything feel impossible. Here is what I actually did, and what our customers and health practitioners tell us works.
Why Do Prenatal Vitamins Make You Feel Nauseous?
Before the hacks, the explanation. Because if you know why it is happening, the fix makes more sense.
The most common culprit is iron. High iron content, especially certain forms like ferrous sulfate, can irritate a sensitive stomach. Ferrous fumarate and ferrous sulfate are the two forms I see most commonly in off-the-shelf prenatals, and they are the two most likely to cause nausea, bloating and digestive upset. If your prenatal contains either of those, the supplement itself may be contributing to how you feel.
The second culprit is capsule size. A large capsule on a nauseous stomach triggers a gag reflex for a lot of women, regardless of what is inside it.
The third is smell. Pregnancy heightens sensitivity to scent significantly, and many prenatal formulas have a strong vitamin smell that can trigger nausea before the capsule even reaches your mouth.

Could My Prenatal Formula Itself Be the Problem?
Yes, and this is worth knowing before trying any of the hacks below.
If your prenatal contains iron in a poorly absorbed form (ferrous sulfate or ferrous fumarate), the simplest fix is switching to an iron-free formula and supplementing iron separately based on your blood test results.
The moode approach specifically: The Prenatal by moode is iron-free, so iron can be added at the dose your levels actually indicate rather than taken as a blanket ingredient that may not match your needs. Always read the label and follow directions for use.
If your prenatal has a strong smell or a large capsule size, that alone is worth considering when choosing your next bottle.
What Actually Helps When Prenatal Vitamins Trigger Nausea
Move the Bottle Away Before You Open It
This was my most-used trick. I would open the bottle, remove my daily dose, close the lid, and move the bottle to the other side of the room before I took anything. You cannot smell what is out of reach. It sounds absurdly simple. It worked every time.
Open the Capsules Into a Smoothie
moode capsules can be twisted open and the powder stirred into anything cold. Smoothies, yoghurt, chia pudding, juice, even ice cream if that is what you can stomach. The powder is completely tasteless and the nutrients are not affected because there is no heat involved. This is one of the most consistent pieces of feedback we get from customers who struggled with swallowing capsules, particularly in the first trimester. For a recipe built specifically around this workaround, see Nutritionist Lilly Lloyd's Prenatal Bliss Balls.
Take Them After Food, Not Before
Always take your supplements on a full stomach, ideally right after you eat. This reduces the risk of nutrients irritating the gut lining and causing or worsening symptoms of nausea. The timing matters more than most people realise. A prenatal on an empty stomach is a different experience entirely to the same prenatal thirty minutes after a meal.
Try Bedtime Instead of Morning
If morning is when nausea peaks, there is no rule that prenatals must be taken in the morning. Taking them at bedtime helps you avoid feeling sick throughout the day. You sleep through the digestion window and wake up without the association between the capsule and the nausea that can build over time.
Split the Dose Across Meals
Two capsules daily does not have to mean two capsules at once. Taking one with lunch and one with dinner distributes the nutrient load and reduces the likelihood of any single dose causing a reaction. If your vitamins consist of multiple capsules, try spreading them out over two or three meals to help you keep them down.
Use B6 and Ginger as Additional Support
Research suggests that taking vitamin B6 supplements may help with mild nausea in pregnancy. Ginger can also be helpful. The Prenatal by moode contains vitamin B6 in its active form (pyridoxal-5-phosphate). On days when nausea was particularly significant during my pregnancy, I would add ginger to whatever I was eating alongside taking the capsule, even just ginger tea or a piece of crystallised ginger. A 2014 meta-analysis published in the Journal of the American Board of Family Medicine found that 1g of ginger daily for at least four days was associated with a fivefold improvement in pregnancy nausea.

What Our Customers Tell Us
The feedback we hear most often is that the smell is the first hurdle, and the capsule size is the second. The move-the-bottle trick has been shared in our community more than once. The smoothie trick is the most popular workaround for customers who genuinely cannot swallow capsules during the first trimester.
What we also hear is that switching away from iron-containing prenatals made a significant difference for a number of women. If you have been told your nausea is just pregnancy and to push through it, it is worth asking what is in your current formula before accepting that.
Is It the Prenatal or Is It Pregnancy Nausea?
It can be both, and it can be hard to separate. A useful way to tell: if the nausea spikes specifically in the 30 to 60 minutes after taking your prenatal, the supplement is likely contributing. If the nausea is consistent regardless of timing, it is more likely to be pregnancy itself.
Either way, the hacks above help with both. A prenatal you can consistently take, in a form your body tolerates, on a full stomach, at the time of day you feel best, is what actually gets nutrients to you and your baby. Consistency matters more than perfection.
moode Answers Your Questions About Prenatal Vitamins and Nausea
Why does my prenatal vitamin make me feel sick?
The most common causes are iron in a poorly absorbed form (ferrous sulfate or ferrous fumarate), a large capsule size that triggers a gag reflex, or a strong smell that worsens because of the heightened sensitivity to scent that comes with pregnancy. Taking your prenatal on an empty stomach significantly increases the likelihood of nausea. Start by taking it after food rather than before.
Can I open my prenatal capsules and add them to food?
Yes, if your prenatal comes in capsule form. The powder can be stirred into cold foods including smoothies, yoghurt, juice or chia pudding without affecting the nutrients, as no heat is involved. moode capsules are designed to be opened this way. The powder inside The Prenatal by moode is tasteless. For a recipe built around this idea, see the Prenatal Bliss Balls recipe by Nutritionist Lilly Lloyd.
Should I stop taking my prenatal if it makes me nauseous?
Not without speaking to your healthcare provider first. The nutrients in a prenatal are important throughout pregnancy, and stopping entirely is not recommended without a conversation about alternatives. Instead, try changing the timing, taking it with food, opening the capsule into a smoothie, or discussing a formula switch with your GP or naturopath.
When is the best time of day to take prenatal vitamins if you have nausea?
The time of day when you feel best, which varies by person. For many women in the first trimester, that is bedtime. Taking your prenatal at night means you sleep through the digestion window and avoid the morning association between the capsule and nausea. After food is more important than time of day, but combining both is the most effective approach.
Does an iron-free prenatal reduce nausea?
For many women, yes. Iron is one of the most commonly cited causes of prenatal-related nausea, particularly in the forms ferrous sulfate and ferrous fumarate. An iron-free formula allows you to supplement iron separately at the dose your blood test results indicate, rather than taking a fixed dose that may be causing unnecessary digestive discomfort.
Is it normal to gag at the smell of prenatal vitamins during pregnancy?
Yes. Pregnancy significantly heightens sensitivity to smell, and many prenatal formulas have a strong vitamin odour. Removing your daily dose from the bottle and then moving the bottle away before taking the capsules is a practical way to avoid triggering nausea through smell alone.
A prenatal you can consistently take is what actually gets nutrients to you and your baby. Consistency matters more than perfection.
