You need 450 mg of choline a day during pregnancy and 550 mg while breastfeeding. Most prenatals do not come close. Around 9 in 10 pregnant women in the US fall short, and the fastest way to find out where you stand is to read the supplement facts panel on the bottle you are already taking.
When I was trying to conceive, I read every prenatal label I could get my hands on. Choline was the nutrient that kept surprising me.
It has been officially recognized as essential since 1998.1 The research linking it to a baby's brain development has been building for more than twenty years. And yet on label after label, I found a tiny amount of it, or none at all.
Here is what I wish someone had just told me back then.
How much choline do you need during pregnancy?
450 mg a day in pregnancy. 550 mg a day while breastfeeding.
You may notice choline does not have an official RDA the way folate does. That is because there was not enough evidence to set one, so the National Academy of Medicine set what is called an adequate intake instead.2 It is a best estimate of what covers most healthy people, which makes it a floor to clear rather than a goal to hit.
| If you are | Aim for | Do not exceed |
|---|---|---|
| Not pregnant | 425 mg/day | 3,500 mg/day |
| Pregnant | 450 mg/day | 3,500 mg/day |
| Breastfeeding | 550 mg/day | 3,500 mg/day |
Two things people find surprising. Your need goes up after the baby arrives, not down, because choline gets pulled into your breast milk.
Is your prenatal giving you enough?
Probably not, and it takes about thirty seconds to find out.
Only about 8.5 percent of pregnant women in the US are actually hitting 450 mg. Average intake sits somewhere around 319 mg a day.34 Most of that gap is just diet. Choline is concentrated in eggs, liver and other foods that have quietly drifted off a lot of plates, and intake falls further in the first trimester, when nausea makes those exact foods the hardest ones to face.
Turn your bottle around and look at the supplement facts panel for the word choline. If it is not listed, there is none in there. If it is listed, check the milligrams against 450.
Here is where the popular prenatals actually land.
| Prenatal | Choline per day | Of the 450 mg you need | Sells choline separately? |
|---|---|---|---|
| Mothersense Prenatal+ | 950 mg | 211% | No, it is already in the formula |
| Needed Prenatal Multi Pro | 400 mg | 89% | Yes, 500 mg |
| Beli for Women | 400 mg | 89% | No |
| WeNatal for Her | 400 mg | 89% | No |
| FullWell Women's Prenatal | 300 mg | 67% | No |
| MegaFood Baby & Me 2 | 300 mg | 67% | No |
| Perelel Trimester Pack | 120 mg | 27% | Yes, 550 mg |
| Thorne Basic Prenatal | 110 mg | 24% | No |
| One A Day Prenatal Advanced | 110 mg | 24% | No |
| Ritual Essential Prenatal | 55 mg | 12% | Yes, 550 mg |
| Nature Made Prenatal Multi + DHA | 0 mg | 0% | No |
One thing to watch if you are comparing prices. Three of these brands sell a separate choline supplement to make up for what their prenatal is missing. If you would need to buy both, compare the total monthly cost, not just the price of the multivitamin.
Why do most prenatals leave choline out?
It comes down to space and money, not science.
Choline is bulky. A meaningful dose takes up real room, and a prenatal already carrying fifteen to twenty five other nutrients cannot squeeze several hundred milligrams of it into one or two capsules. Something has to go, and choline is usually what goes. Good choline ingredients also cost more than the cheap vitamins sitting beside them on the label.
This is not a fringe concern, either. In 2017, the American Medical Association voted to support evidence based amounts of choline in all prenatal vitamins, noting at the time that prenatals contained only 0 to 55 mg of it.5 The American Academy of Pediatrics lists choline among the nutrients that matter most for early brain development.6
What does choline actually do?
Three jobs, mainly.8
- It builds cell membranes. Choline becomes phosphatidylcholine, the main structural material in every cell your baby is building.
- It helps make acetylcholine, a chemical messenger tied to memory, mood, and muscle control.
- It works with folate. The two share a job in something called the methylation cycle, which matters for neural tube development. When one runs low, your body leans harder on the other.
What does the research actually show?
The most encouraging study comes out of Cornell. Women in their third trimester ate a controlled diet and took a supplement, landing at either 480 mg or 930 mg of choline a day. Their babies were tested through the first year, and the babies whose moms had more choline processed what they saw slightly faster.9 Researchers found the same children again at age seven and they did better at holding their focus during a long, boring task.10
A second set of studies gave mothers a related compound called phosphatidylcholine from around 17 weeks of pregnancy, then gave the babies it directly until about three months old. At five weeks, the supplemented babies were better at tuning out a repeated sound, which is an early sign of a brain filtering information well. By thirteen weeks, that difference had disappeared.11 A follow up rated the same children at 40 months and found less social withdrawal.12
Two large reviews looked at all of this together and landed in different places. A 2022 review found that low choline was linked to a higher risk of neural tube defects, and concluded higher intakes were likely to help with memory, attention, and learning.13 A 2025 review looked at the same handful of trials, judged them too small to draw conclusions from, and said the evidence is not strong enough to settle the question either way.14
So here is my honest read. Choline is essential, that is not in question. Most of us are not getting enough, and that is well documented. The reasons it should matter for your baby's brain are strong.
The study details, if you want them
The Cornell trial. A randomized, double blind, controlled feeding study. Everyone ate the same diet supplying 380 mg of choline, plus a supplement of either 100 mg or 550 mg, for total intakes of 480 mg or 930 mg a day through the third trimester. Twenty six women completed it, thirteen per group, and 24 babies were tested. The higher group's reaction time was about 23 milliseconds faster, averaged over tests at 4, 7, 10 and 13 months, and that reached statistical significance. A second measure in the same task, testing visuospatial memory, showed no difference at all. The seven year follow up included 20 children, nine and eleven between the groups, and found better sustained attention on both the main score and the ability to hold accuracy across a twelve minute task, with no differences in false alarms or missed responses.
The phosphatidylcholine trials. Mothers took 3,600 mg in the morning and 2,700 mg at night, roughly 900 mg of choline a day, starting around 17 weeks. Babies then received it directly from birth to about three months, which makes this a perinatal design rather than a prenatal one. At about five weeks, 76 percent of supplemented infants showed intact P50 auditory sensory gating versus 43 percent on placebo. One hundred women were randomized and 83 infants were in that analysis. By the second recording near thirteen weeks the groups were 76 percent and 72 percent, so the effect looks temporary. At 40 months, only 49 of the original 100 families were still being assessed, and that assessment was never planned before the trial started. Both the attention and withdrawn scores were lower in the supplemented group, but after correcting for the ten subscales tested, only withdrawn remained significant. The withdrawn effect also varied by CHRNA7 genotype, so it did not apply evenly to every child.
The reviews. The 2022 review pooled five case control studies and found an odds ratio of 1.36 for neural tube defects with low choline, with a confidence interval of 1.11 to 1.67 and a wider prediction interval of 0.78 to 2.36, meaning the link may not hold in every population. It also noted low confidence in blood choline as a measure of intake. The 2025 review covered four randomized trials and five observational studies, declined to pool them because they were too different to combine, reported that most measured outcomes did not support the hypothesis, and described the trials as too small to detect a realistic effect.
Can you get enough choline from food?
Yes, you can.
| Food | Serving | Choline |
|---|---|---|
| Beef liver, pan fried | 3 ounces | 356 mg |
| Egg, hard boiled | 1 large, whole | 147 mg |
| Salmon, farmed Atlantic | 3 ounces | about 77 mg |
| Milk, 1% fat | 1 cup | 43 mg |
Reaching 450 mg from food alone means about three whole eggs a day, every day, or liver on a regular basis. The choline sits in the yolk, so an egg white omelet does not count toward it.
That is completely doable for some people. It is also not remotely realistic if eggs make you gag, if you eat plant based, or if you are in a first trimester that has turned you against protein entirely. Neither answer is wrong. You just want to know which one you are working with.
Is 950 mg of choline too much?
No. The ceiling for adults is 3,500 mg a day, so 950 mg sits at about a quarter of it, and close to the 930 mg used in the Cornell study.
Being above the 450 mg target is not the same as being near the limit, and those two ideas get mixed up constantly. The 450 is a floor, not a maximum.
One honest note. At higher intakes, some people notice a faintly fishy body odor, and that is one of the two effects the upper limit was set to avoid. If you are pregnant, on a prescription medication, or living with a liver or kidney condition, talk to your OB or midwife about what is right for you. This is education, not medical advice, and it is no substitute for someone who knows your history.
How we handle choline at Mothersense
I built Prenatal+ around the nutrients that get squeezed out of smaller formulas, and choline was first on my list.
Each daily sachet has 950 mg of choline from two sources, choline bitartrate and Alpha-GPC, because they work in slightly different ways and together they cover more ground than either does alone.
It is also why a sachet holds seven pieces instead of one or two. You tear open one packet a day and take three tablets and four softgels, two of which are the choline. Meaningful doses of choline, omega 3s and chelated minerals genuinely do not fit into a couple of capsules. Most brands solve that by quietly cutting the doses. We solved it with a bigger packet. Take yours with a meal to help prevent stomach upset.
Every batch is third party tested for identity, potency and purity, and there are no proprietary blends on our label. You can see every nutrient and every amount on the ingredients page, and the research behind the formula on our research page.
What to do next
- Read your label. Find choline on the supplement facts panel and compare the milligrams to 450.
- Add up everything. If you take a separate choline supplement, count it toward your total.
- Close the gap. Either build the difference from eggs and other whole foods, or switch to a prenatal that includes a real dose.
- Bring it to your next appointment. Your provider can weigh it against everything else they know about you, which is something no article can do.
Common questions
How much choline should I take during pregnancy?
Aim for 450 mg a day during pregnancy and 550 mg a day while breastfeeding. That total includes choline from both food and supplements. The upper limit for adults is 3,500 mg a day.
Is 950 mg of choline too much during pregnancy?
No. It sits well under the 3,500 mg upper limit for adults, and close to the 930 mg a day used in the Cornell study. The 450 mg figure is a floor to clear, not a maximum. Talk with your OB or midwife about what is right for you.
Which trimester is choline most important?
All of them. Choline supports neural tube development in the earliest weeks and brain development the whole way through. The trials that found neurodevelopmental effects supplemented in the second and third trimesters. Your need then rises again after birth, to 550 mg a day while breastfeeding.
Do I need a separate choline supplement?
It depends on what is already in your prenatal. Several popular prenatals contain 55 to 120 mg and sell a separate choline product to cover the gap. If your prenatal already has a real dose, a second supplement is redundant. Read the label and add up the total.
Can I get enough choline from eggs alone?
One large whole egg has about 147 mg, so reaching 450 mg from eggs means roughly three a day, every day. The choline is in the yolk, so egg whites do not count. That works for some people and is unrealistic for anyone with an egg aversion, a plant based diet, or first trimester nausea.
Does choline cause a fishy smell?
At high intakes it can, in some people. It happens when gut bacteria convert choline into a compound called trimethylamine, and it is one of the two effects the upper limit was set to avoid. Most people never notice it. If you do, mention it to your provider rather than stopping a nutrient your baby needs.
Should I keep taking choline while breastfeeding?
Yes. Your need goes up rather than down after birth, from 450 mg to 550 mg a day, because choline is drawn into your breast milk. It is one of the main reasons stopping a prenatal on delivery day is worth reconsidering.
Is choline the same as folate?
No, though they are related. Both act as methyl donors in the methylation cycle and both matter for neural tube development, but they are separate nutrients with separate requirements. A good prenatal needs enough of each. When one runs low, your body leans harder on the other.
