Choline in Pregnancy: The Nutrient Most Women Are Missing

1 in 3 pregnant women are choline deficient — and the vast majority don't know it. It's not because they're not trying. It's because choline doesn't get nearly the same attention as folate or iron, even though research increasingly shows it's just as critical for your baby's brain development.

This article explains what choline does, how much you need during pregnancy, the best food sources, and why your prenatal vitamin probably isn't covering it.

What Is Choline, and Why Does It Matter?

Choline is an essential nutrient — your body can make small amounts of it, but not enough, especially during pregnancy. It plays a critical role in three areas that matter deeply during the prenatal period:

• Brain development: Choline is a key building block of acetylcholine, the neurotransmitter responsible for memory and learning. Studies show that higher choline intake during pregnancy is associated with better cognitive function in children.
• Neural tube formation: Like folate, choline helps close the neural tube in early pregnancy. It works through a different biological pathway, which means even women who get plenty of folate may still be at risk if choline is low.
• Placenta function: Choline supports healthy placental development and is critical for transporting nutrients from your body to your baby.

The American Medical Association and the American Academy of Pediatrics have both highlighted choline as an underconsumed nutrient in pregnancy — yet it still doesn't appear on most prenatal vitamin labels.

How Much Choline Do You Need During Pregnancy?

It's worth noting that some researchers believe the current 450 mg recommendation may be too low. A Cornell University study found that women consuming 930 mg of choline per day had babies with significantly better information processing speeds at 4, 7, and 10 months compared to those consuming 480 mg. More research is ongoing.

The Best Food Sources of Choline in Pregnancy

Eggs are by far the richest common source of choline — one large egg provides around 147 mg, almost a third of your daily target. Here are the top sources:

A practical day of choline-rich eating

Here's how you'd hit 450 mg on a typical day without going out of your way:

• Breakfast: 2-egg scramble with broccoli = ~355 mg
• Lunch: Chicken and edamame grain bowl = ~160 mg
• Snack: Greek yogurt = ~38 mg

That gets you to ~553 mg — above the recommended daily intake — without any supplements.

Does Your Prenatal Vitamin Cover Choline?

Almost certainly not. Most prenatal vitamins contain zero choline. A 2019 review found that of 25 common prenatal vitamins, only 10 contained any choline at all — and those that did contained an average of just 55 mg, about 12% of the daily target.

Some newer prenatal vitamins (like Needed, Ritual, and Perelel) do include meaningful amounts of choline. If yours doesn't, food is the most reliable and bioavailable source.

Getting Enough Choline on a Plant-Based Diet

If you're vegetarian or vegan, eggs are the most efficient plant-friendly choline source. Beyond that, focus on edamame, shiitake mushrooms, kidney beans, and broccoli. It's harder to hit 450 mg without eggs — but it's doable with intentional meal planning.

If you're vegan, a choline supplement (available as choline bitartrate or CDP-choline) is worth discussing with your OB or midwife, particularly in the first and third trimesters.

The Easiest Way to Track Your Choline Intake

Most nutrition apps — including popular ones like MyFitnessPal — don't surface choline as a tracked nutrient. It gets buried or omitted entirely. This is one of the reasons so many pregnant women are deficient: the apps aren't making it visible.

NourishedBaby was built specifically to track the 10 nutrients that matter most in pregnancy, including choline. Log a meal by photo, voice, or text, and your choline count updates in real time — with a daily insight that tells you exactly what to eat to close any gap before the end of the day.
