Most pregnant women don’t get enough choline, and most prenatal vitamins don’t include much. That leads a lot of moms to wonder whether they should take a separate choline supplement. For most women, food can close the gap; a supplement makes the most sense when your diet can’t.

The short version

  • Not routine: no U.S. guideline currently recommends a choline supplement for every pregnant woman, according to the NIH.
  • Food first: eggs, meat, fish, and dairy are the richest sources. Two eggs give you about 294 mg of the 450 mg you need.
  • Who might need one: women who don’t eat eggs or other animal foods, or who can’t reach 450 mg (550 mg while breastfeeding) from food.
  • Check your prenatal first: fewer than half include choline, usually about 25 mg.
  • Safe range: supplements usually contain 10 to 250 mg. The upper limit from all sources is 3,500 mg a day (3,000 mg for teens).
  • Talk with your provider before adding any supplement during pregnancy.

Do you need one?

Start by estimating what you eat on a typical day. Our guide to choline-rich foods for pregnancy lists amounts for common foods. If you regularly eat eggs, meat, fish, or dairy, you may be close to the 450 mg mark already.

A supplement is worth discussing with your doctor or midwife if:

  • You don’t eat eggs or other animal foods. Even a well-planned vegan day tends to land short of 450 mg.
  • You’re breastfeeding. Your need rises to 550 mg a day.
  • Food aversions or nausea have narrowed what you can eat. That’s common in the first trimester.

The NIH also notes that pregnant and breastfeeding women may be more likely to run low on choline if they don’t take folic acid or have low vitamin B12, because those nutrients share some of choline’s work in the body. If either applies to you, fix that first: take your folic acid, and ask about B12.

What the research and guidelines say

What’s well established. Your needs rise in pregnancy (450 mg a day) and breastfeeding (550 mg), and about 90% to 95% of pregnant women in the U.S. get less than that, according to the NIH. ACOG lists choline among the nutrients you need during pregnancy.

What’s still being studied. Choline is involved in early brain development, and researchers are testing whether extra choline during pregnancy helps children’s attention and memory. Those studies are promising but small, and they haven’t yet led to a U.S. guideline recommending supplements for everyone. Some studies have linked low choline levels to neural tube defects; others found no link.

What isn’t known. Supplements use different forms of choline, and no studies have compared how well the body absorbs each one, according to the NIH.

So getting the recommended amount matters, and there’s little evidence so far that going far above it helps. That makes food the first choice and a supplement a way to fill a real gap.

Reading the label

Check your prenatal vitamin first. Only about 40% of prenatal vitamins contain choline, and the median amount in those is about 25 mg, according to the NIH. Look for “choline” on the Supplement Facts panel. If it isn’t listed, there’s none.

Forms you’ll see. Choline supplements usually contain choline bitartrate, phosphatidylcholine, or lecithin. Typical amounts range from 10 to 250 mg, according to the NIH. Some products list the weight of the whole compound on the front, so compare the amount of choline itself in the Supplement Facts panel.

Look for independent testing. Choose a product with a seal from U.S. Pharmacopeia (USP), NSF, or ConsumerLab, which test whether a supplement contains what its label says.

Add it up. Count the choline from your prenatal, any separate supplement, and food together. For most women, a modest supplement on top of a reasonable diet stays far below the upper limit.

Safety

  • Upper limit: 3,500 mg a day for adults and 3,000 mg for teens, including during pregnancy and breastfeeding, from food and supplements combined, according to the NIH.
  • Side effects of very high intakes: a fishy body odor, vomiting, heavy sweating and salivation, low blood pressure, and liver problems. These limits are set well above what food and typical supplements provide.
  • A research question to know about: gut bacteria turn some choline into a substance called TMAO, which some studies have linked to heart disease risk. The research is still developing, and it isn’t a reason to avoid choline-rich foods or the recommended amount.
  • Medicines: choline isn’t known to interact with medicines in any meaningful way.
  • Your baby: after birth, breast milk, formula, and food should be your baby’s only sources of choline. Don’t give a baby choline supplements.

What to do now

  • Check your prenatal vitamin label for choline.
  • Estimate your choline from food for a typical day using our foods guide.
  • If you’re well under 450 mg (550 mg if breastfeeding), ask your provider whether a supplement makes sense and how much.
  • Keep taking folic acid.
