Target Levels for Pregnancy Choline
- Target intake: ~450–480 mg/day in pregnancy (IOM/ACOG 450 mg; EFSA 480 mg).
- Most women fall short from diet alone; many prenatal multis contain little or no choline.
- Top foods: eggs, liver, meats, fish, soy/edamame, wheat germ; plant-only diets need careful planning.
- Who recommends? ACOG lists 450 mg/day; AMA (2017) urged adding evidence-based choline to all prenatals; EFSA AI is 480 mg/day in pregnancy.
- Why supplement? Intake gaps + growing RCT evidence for neurodevelopment benefits; verify label claims.
What is choline—and why it’s pivotal in pregnancy
Choline is an essential nutrient used to build fetal brain cell membranes (phosphatidylcholine), produce the neurotransmitter acetylcholine, and support methylation and placental function. In pregnancy your requirement rises, and most women do not meet the AI from food alone.
How much do you need?
- ACOG/IOM (US): 450 mg/day in pregnancy.
- EFSA (EU): 480 mg/day in pregnancy; 520 mg/day in lactation.
Practical aim: hit ~450–480 mg/day from diet + supplement and avoid megadoses unless under clinical supervision (UL: 3,000–3,500 mg/day depending on age).
Evidence snapshot: what the studies show
- Randomised controlled feeding trial (Cornell): Third-trimester choline at 930 mg/day vs 480 mg/day improved infants’ information processing speed. Benefits persisted as better sustained attention at 7 years in follow-up.
- Population intake data: 90–95% of pregnant women consume less than the AI; many prenatals provide 0–55 mg choline—far below needs.
- UK concern: BMJ Nutrition commentary warned we may be overlooking a choline gap in the UK, partly because it’s absent from core UK surveys and guidance.
Take-home: The combination of higher needs, low dietary intakes, and measurable child neurocognitive benefits in RCTs is why expert bodies increasingly highlight choline in prenatal care.
Best dietary sources of choline (with UK-friendly examples)
If you eat eggs or organ meats, you can cover a large share of your daily target quickly:
- Eggs (1 large): ~147 mg
- Beef liver (85–100 g cooked): ~356–418 mg
- Chicken liver (100 g): ~290 mg
- Roasted soybeans / edamame (per 100 g): ~107–116 mg
- Wheat germ (100 g): ~152 mg
- Chicken breast, beef, cod (100 g): ~70–120 mg
Plant-based caution: Choline is present in legumes, crucifers, nuts and seeds—but typically at lower densities; vegans may need a targeted plan and supplementation to reach 450–480 mg/day.
Why supplement—and who says so?
1) Intake gaps: Even varied diets frequently miss the target; many prenatal multis omit choline or include minimal amounts, so a separate choline supplement is often required.
2) Clinical signals: RCTs indicate neurodevelopment benefits when maternal intake is raised in late pregnancy.
3) Policy signals:
- ACOG lists 450 mg/day and names major food sources for pregnant patients.
- AMA (2017) resolved to support evidence-based amounts of choline in all prenatal vitamins.
- EFSA sets 480 mg/day AI in pregnancy for Europe.
How to choose a pregnancy choline supplement (UK)
Forms:
- Choline bitartrate (widely used, cost-effective).
- Phosphatidylcholine (PC) (lipid form; gentler for some, often pricier).
Dose strategy:
- If your diet already contributes ~250–300 mg (e.g., two eggs = ~300 mg), a 200–250 mg supplement can close the gap.
- If egg-free/plant-based, consider 350–450 mg/day supplemental choline, adjusting for your diet and prenatal multi.
Quality checklist:
- UK/EU GMP manufacturing, published COA, heavy-metal screening, and transparent choline mg per serving.
- If relying on a prenatal multi, check the label: many list 0–55 mg, which is not enough.
Safety, side-effects, and upper limits
Choline is well-tolerated at pregnancy-appropriate intakes. Very high doses can cause fishy body odour (trimethylamine), GI upset, or hypotension. UL: 3,000–3,500 mg/day (age-dependent). Discuss any high-dose regimen with your clinician, especially if you have liver, renal, or methylation issues.
Frequently searched questions
Is choline recommended in pregnancy?
Yes. ACOG educates patients to get ~450 mg/day; EFSA sets an AI of 480 mg/day. AMA urged adding choline to all prenatals (2017).
Do UK prenatal vitamins include enough choline?
Often no. Independent reviews show many prenatal multis contain little or no choline, or miss label claims; consider a dedicated choline supplement if your prenatal is low.
What are the best food sources?
Eggs and liver top the list; good contributions from meat, fish, dairy, soy/edamame, wheat germ; many fruits/veg are relatively low.
Can higher choline improve baby’s brain development?
An RCT increasing maternal choline to 930 mg/day in late pregnancy improved infant processing speed and child attention at 7 years. Evidence is promising and growing.
How much is too much?
Stay near the AI (450–480 mg/day) unless advised; avoid exceeding UL (3,000–3,500 mg/day).

Actionable checklist for UK readers
✅ Audit your plate (eggs/soy/meat/fish/wheat germ).
✅ Read your prenatal label—how many mg choline?
✅ Top up with choline bitartrate or phosphatidylcholine to reach 450–480 mg/day combined.
✅ Ask for COAs and heavy-metal testing if choosing non-NHS brands; prefer UK/EU GMP.
