Key takeaways:
✨ Choline is vital for fetal growth and brain development. It’s involved in cell membrane structure, neurotransmitter synthesis, and methylation pathways, all foundational processes during pregnancy. 
✨ Supplementation in pregnancy has been linked with improvements in cognitive outcomes in children. Higher maternal choline intake appears to support aspects of child memory and learning. 
✨ Choline has been recognised as an essential nutrient since the late 1990s, and this review included studies where pregnant women received supplemental choline in various forms (e.g., choline chloride, phosphatidylcholine).
✨ Because demands for choline increase during pregnancy (due to growth and metabolic needs), many women may not meet optimal intakes through diet alone. 
Food sources of choline:
• Eggs
• Liver
• Poultry
• Fish
• Soy products
• Cruciferous vegetables
Why this matters
Choline supports methylation, neurological development, and placental function, all of which lay the foundation for long-term health for both parent and baby. Supplementing appropriately before and during pregnancy may help fill dietary gaps and potentially benefit child development outcomes.
