Eating for the baby's brain in pregnancy

How much choline do you need during pregnancy?

Quick answer

The US target for choline in pregnancy is 450 mg a day, rising to 550 mg while breastfeeding (Europe's EFSA says 480 mg in pregnancy). Fewer than 1 in 10 US pregnant women reach it, and most prenatals contain little or none. One large egg has about 147 mg, so two eggs plus a few other foods usually gets you there.

The numbers

WhoDaily target
Women, not pregnant425 mg
Pregnant (US)450 mg
Breastfeeding (US)550 mg
Pregnant (European Food Safety Authority)480 mg
Safe upper limit, adults 19+3,500 mg
Safe upper limit, ages 14-183,000 mg

These targets are called Adequate Intakes. Falling below one isn't a diagnosis of deficiency, so there's no need to panic over a low day. Think of 450 mg as the line to aim for most days.

If you've read conflicting numbers online, this is usually why: the US and Europe set slightly different targets, and some researchers think 450 mg may be on the low side for pregnancy. Supplement labels add more confusion, which we'll get to below.

What choline does for a growing brain

Your body makes a little choline, but not enough, so the rest has to come from food. During pregnancy your baby uses it in three big ways:

  • Building cell walls. Every new brain cell needs an outer membrane, and choline is needed to make its main fats. One of them is also part of myelin, the coating that helps nerve signals travel fast.
  • Making a memory messenger. Choline is used to make acetylcholine, a chemical messenger that helps guide how new nerve cells form and connect. It supports normal development of the hippocampus, the brain's learning and memory hub.
  • Switching genes on and off. Choline supplies the tiny chemical tags the body uses to mark DNA. Folate shares the same pathway, which is why the two are often studied together.

Choline also helps carry DHA, the omega-3 brain fat, to your baby. One more reason eggs and fish make a good pair.

Why most women fall short

In US national survey data, only about 8.5% of pregnant women reached the 450 mg target. US pregnant women average roughly 320 mg a day. Choline is most concentrated in animal foods such as eggs, meat and fish, so intake drops fast if you eat few eggs, cut back on meat, or can't face food in the first trimester. It isn't only a US problem: in an Australian national survey, pregnant women averaged 251 mg a day, and fewer than 1% reached their target of 440 mg.

Your prenatal probably won't fill the gap. The NIH says prenatal supplements "typically contain little if any choline." A 2025 lab test of 47 US prenatals found that only 12 listed choline at all, and only 5 of those contained the amount on the label. In 2017 the American Medical Association called for "evidence-based" amounts of choline in prenatals, and in 2018 the American Academy of Pediatrics called choline a "brain-building" nutrient. Labels haven't caught up. See what to look for in a prenatal.

What the research shows, honestly

At Cornell University, 26 women in their third trimester ate either 480 mg of choline a day or 930 mg. Babies in the 930 mg group were faster on a reaction-time test in their first year. At age 7, the 20 children who were retested did better on a 12-minute attention task.

That's promising, and it's small. There was no placebo group, the tests were lab tasks, and nobody measured IQ. Other trials are mixed, and the largest one, 140 women in North Carolina, found no effect. A 2025 review of the trials and cohort studies concluded that the evidence is "insufficient to support or refute" the idea that extra choline improves a child's brain development.

So here's the fair summary. Choline is clearly needed for brain building, most women don't get enough, and reaching the 450 mg target is a sensible, safe goal. Whether going higher helps is still an open question. If your doctor says choline doesn't matter much, you can share the AAP and AMA positions above and ask how to reach the target.

A day that hits 450 mg

Other good sources per serving: beef top round (117 mg per 3 oz), roasted soybeans (107 mg per half cup), cod (71 mg per 3 oz) and a large baked red potato (57 mg). Cook eggs until the yolk and white are firm. Skip liver: it's the richest choline food, but it's also very high in vitamin A, and the NHS advises avoiding liver in pregnancy. For more on eggs, see how many eggs you can eat. If you don't eat eggs, our vegetarian guide shows a plant-based day.

If you use a supplement

Count your food first, then fill only the difference. On a label, look for a line that says "Choline" with an amount in mg. Choline bitartrate and choline chloride are common forms. Be careful with "lecithin": it holds far less choline than its number suggests, so "lecithin 500 mg" is much less than 500 mg of choline. Typical choline supplements contain 10 to 250 mg. Bring your prenatal bottle and your food estimate to your doctor before adding one. Food and normal supplement amounts are nowhere near the 3,500 mg upper limit.

Do this

  • Read your prenatal label tonight and write down how much choline it has, if any.
  • Hard-boil six eggs at a time and eat two most days.
  • Add one other choline food each day: chicken, beef, cod, soybeans, beans or milk.
  • Count your choline for one ordinary day using the table to see where you stand.
  • Keep going while breastfeeding, when the target rises to 550 mg.

When to ask your doctor

Check with your doctor or midwife first if…

  • You're vegan, don't eat eggs or keep falling short, and are thinking about a supplement.
  • You take prescribed medicines or have a medical condition that affects your diet.
  • You're under 19, since the safe upper limit is lower (3,000 mg).

Call your doctor now if…

  • You can't keep food or fluids down for 24 hours.
  • You have vaginal bleeding, fluid leaking or severe belly pain (call your doctor or 911 now).

Does my prenatal have enough choline?

Probably not. The NIH says prenatals typically contain little if any choline. In a 2025 test of 47 US prenatals, only 12 listed it, and only 5 of those contained the labeled amount. Check your label and plan to get most of your choline from food.

Can you get too much choline?

The safe upper limit for adults is 3,500 mg a day. Very high doses, around 10,000 to 16,000 mg a day, have caused a fishy body odor, vomiting and sweating. Food and normal supplement amounts are nowhere near that.

Is choline the same as folic acid?

No. They're different nutrients that share some of the same chemical pathways in the body. You need both. Folic acid has a clear supplement target (400 mcg a day), while choline mostly comes from food like eggs, meat, fish and beans.

Do I need more choline while breastfeeding?

Yes. The US target rises to 550 mg a day while breastfeeding, because your baby's brain keeps growing fast after birth. One large egg still gives about 147 mg toward it. If you're formula feeding, most infant formulas have choline added and your own target goes back to 425 mg.

How many eggs can I eat a day while pregnant?For most healthy pregnant women, eggs are an everyday food, and two a day is a practical target. Each large egg has about 147 mg of choline, roughly a third of the 450 mg you need daily, plus some iodine and vitamin D. Cook them until the yolk and white are firm. You don't need six a day.How can vegetarians get enough choline and DHA during pregnancy?If you eat eggs and dairy, choline is easy: two eggs give about 294 mg of the 450 mg daily target. Vegans can get close with soybeans, beans, quinoa and potatoes but often fall short. For DHA, plant omega-3 converts poorly, so algal oil is the practical source. Ask your provider about both supplements, plus B12, iron and iodine.What should I look for in a prenatal vitamin?Look for at least 400 mcg of folic acid and 150 mcg of iodine (as potassium iodide). Then check for choline, which most prenatals leave out, and for DHA, which often comes as a separate softgel. Skip cod liver oil and separate vitamin A (retinol) supplements. Bring the bottle to your doctor or midwife and ask if it fits you.What should I eat while breastfeeding to support my baby's brain?Eat 8 to 12 ounces a week of lower-mercury fish, an egg most days, and use iodized salt. Breast milk's DHA and iodine rise and fall with your diet, and your choline needs peak at 550 mg a day while breastfeeding. Ask your doctor whether to keep your prenatal and whether it has 150 mcg of iodine.What should I eat during pregnancy for my baby's brain development?Focus on a handful of brain nutrients: choline from eggs, DHA from 8 to 12 ounces a week of low-mercury fish like salmon and sardines, iodine from dairy and iodized salt, iron from meat, beans and fortified cereal, and folate from greens plus your prenatal's folic acid. You don't need to eat for two. Better food matters more than more food.Should I take DHA during pregnancy?DHA is worth getting in pregnancy, and fish is the best place to start: 8 to 12 ounces a week of low-mercury fish. If you eat little or no fish, ask your doctor about a fish oil or algal DHA supplement. Across 70 trials, omega-3 in pregnancy cut early preterm birth by 42%, most clearly in women who eat little fish.
