Choline During Pregnancy: The Nutrient Most Prenatal Vitamins Don't Include

You've probably heard about folate. Most people have. The connection between folate and neural tube defects has been part of prenatal care messaging for decades, and it shows up in every prenatal vitamin on the market.

Choline is different. It plays some of the same roles as folate in early fetal development, it's recommended by ACOG, and yet most prenatal vitamins contain little to none of it. Survey data from the United States consistently show that fewer than 10% of pregnant women reach the recommended daily amount through diet alone.

This isn't because choline doesn't matter. It's because, unlike folate, it never got the same public health attention.

What Choline Actually Does

Choline is an essential nutrient your body uses for several things, but during pregnancy three of them stand out.

Cell membrane development. Every new cell your baby forms needs choline to build its membrane. Given that early pregnancy involves rapid cell division on a scale that doesn't happen at any other point in life, the demand increases significantly.

Neural tube development. Like folate, choline plays a role in the formation of the neural tube, the structure that becomes the brain and spinal cord. ACOG notes that choline may help prevent some birth defects, though folate remains the primary nutrient associated with neural tube defect prevention.

Brain development. Choline is used to produce acetylcholine, a neurotransmitter involved in memory and attention. Research from the University of Colorado has looked at how choline levels in the mother during pregnancy relate to the development of neural inhibition in the fetal brain, a process considered important for healthy brain function across the lifespan. A Cornell University study published in 2022 followed children of mothers who received higher choline intake during their third trimester and found that at age seven, those children performed better on a sustained attention task compared to children whose mothers received the standard recommended amount.

It's worth being clear about what that research does and doesn't show. A 2025 systematic review in MDPI found that current evidence is insufficient to definitively confirm that higher choline intake improves cognitive outcomes in children. Several trials showed mixed results across different neurodevelopmental measures. The science is promising and the direction is consistent, but it's still developing. What is well-established is choline's structural role in fetal development and the fact that most pregnant women are not getting enough of it.

How Much You Need and How Much Most Women Get

The National Academy of Medicine recommends 450 mg of choline per day during pregnancy, and 550 mg per day while breastfeeding. ACOG uses the same figure.

US survey data, cited by the InfantRisk Center at Texas Tech University Health Sciences Center, shows that the average choline intake among pregnant women is around 319 mg per day. Only about 8.5% reach the recommended amount.

Part of the reason is that choline is concentrated in foods many people don't eat in large quantities every day. Egg yolks are the most significant single source, with around 147 mg per yolk. Beef liver is higher, but few people eat it regularly. Chicken, fish, and legumes contain meaningful amounts, but hitting 450 mg through diet alone requires consistently eating a fairly specific set of foods.

The bigger issue is supplements. ACOG explicitly notes that choline is not found in most prenatal vitamins, or is present in amounts far below the daily recommendation. An evaluation of the top 25 prenatal vitamins found that none contained the full recommended amount, and more than half contained none at all.

This creates a gap that's easy to miss entirely, because people reasonably assume their prenatal vitamin covers their nutritional bases.

Food Sources of Choline

These are the foods that contribute meaningfully to daily choline intake, based on USDA data:

High sources:

• Beef liver (3 oz cooked): around 356 mg
• Egg yolk (one large): around 147 mg
• Chicken liver (3 oz cooked): around 222 mg

Good sources:

• Beef, lean (3 oz cooked): around 72 mg
• Chicken breast (3 oz cooked): around 72 mg
• Atlantic cod (3 oz cooked): around 71 mg
• Salmon (3 oz cooked): around 56 mg
• Eggs, whole (one large): around 147 mg
• Soybeans (half cup cooked): around 107 mg
• Kidney beans (half cup cooked): around 45 mg
• Low-fat milk (one cup): around 40 mg
• Broccoli (half cup cooked): around 31 mg

Getting to 450 mg from food alone is possible, but it typically means eating two to three eggs daily and including meat or legumes at most meals. For someone with first trimester nausea or a restricted diet, it's especially difficult to maintain consistently.

Choline and Your Prenatal Vitamin

If your prenatal vitamin includes choline, check how much. Many that do list it contain between 0 and 50 mg, which leaves a large gap even before accounting for dietary intake. Some newer formulations include higher amounts, but it varies significantly by brand.

The InfantRisk Center notes that because prenatal vitamins are typically insufficient in choline, most pregnant women may benefit from paying closer attention to dietary sources or discussing supplementation with their healthcare provider. As with any supplement during pregnancy, this is worth raising with your OB/GYN or midwife rather than deciding independently.

Choline and Folate: Similar Roles, Very Different Awareness

One reason choline gets overlooked is that folate took the spotlight first. Folate fortification in grain products was mandated in the United States in 1998, which significantly reduced neural tube defect rates, and that success story became the template for prenatal nutrition messaging.

Choline's recommendations were established around the same time, also by the National Academy of Medicine, but without the same policy response or public health push. Current daily choline recommendations for pregnant women were actually set based on data from men, not on pregnancy-specific research, as Cornell researchers have pointed out. Some scientists in this field believe the 450 mg recommendation may need to be revised upward based on more recent findings.

This is why the comparison to folate matters. Not because choline is more important, but because the gap between what's recommended and what most pregnant women actually get is much wider for choline, and the awareness isn't there to close it.

How PregnantWise Tracks Choline

Most nutrition apps don't track choline at all. It doesn't appear on standard food labels, and general calorie counters typically focus on macronutrients rather than pregnancy-specific micronutrients.

PregnantWise tracks choline daily alongside folate, iron, DHA, and 20+ other nutrients, with a goal that reflects the National Academy of Medicine recommendation. When you log food, you can see your choline intake for the day and how close you are to the daily target, the same way you'd track any other nutrient.

Given that most prenatal vitamins don't cover this gap, having visibility into what you're actually getting from food makes a real difference. For more on the nutrients that matter most across each trimester, see our first trimester nutrition guide and our DHA and omega-3 guide.

Frequently Asked Questions

Is choline safe to take as a supplement during pregnancy?

Choline is generally considered safe, but supplementation should be discussed with your healthcare provider before starting. The tolerable upper intake level for choline is 3,500 mg per day for adults, so there is significant room between the recommended 450 mg and levels of concern. However, as with all supplements during pregnancy, your provider is best placed to advise based on your specific situation and diet.

Why doesn't my prenatal vitamin have enough choline?

Choline is a bulky nutrient to include in capsule form, and it has a distinct smell and taste that can make it difficult to formulate into standard prenatal vitamins. This is a known gap in prenatal supplementation and one that researchers and healthcare organizations have been raising, with ACOG among those noting that choline is absent from most prenatal vitamins.

Can I get enough choline from eggs alone?

Eggs are by far the most practical everyday source of choline. Two large eggs provide around 294 mg of choline, which covers about 65% of the daily recommendation for pregnancy. Combined with other sources throughout the day, like chicken, fish, or legumes, two eggs can form a solid foundation. If eggs aren't tolerable due to food aversions, particularly in the first trimester, other sources or supplementation become more important.

Is choline the same as vitamin B?

Choline is sometimes grouped with B vitamins because of functional similarities, and you may see it referred to informally as "vitamin B4" in some contexts. Officially, it's classified as an essential nutrient rather than a vitamin, because the body can produce small amounts of it on its own, though not nearly enough to meet pregnancy needs.

When during pregnancy is choline most important?

Choline is important throughout pregnancy, but particularly in the first trimester when the neural tube is forming, and in the third trimester when the fetal brain is developing rapidly. The Cornell research on sustained attention focused specifically on third trimester choline intake, suggesting the later stages of pregnancy may be especially relevant for brain development.
