Choline

MODERATE EVIDENCESupplementLast updated

SCAN DOSE SUMMARY

Choline is an essential nutrient that 90% of Americans fail to get adequate amounts of — making it one of the most widespread nutritional deficiencies. Our research shows it is critical for liver function (preventing NAFLD), brain development, and acetylcholine synthesis. A 2019 analysis found that choline supplementation during pregnancy increased infant cognitive processing speed by 12%. The TMAO concern (cardiovascular risk from gut bacteria converting choline) is real but must be weighed against the established harms of deficiency.

WHAT IT DOES

Choline serves four critical roles: (1) it's the precursor to acetylcholine, the neurotransmitter essential for memory, muscle control, and attention; (2) it provides methyl groups for DNA methylation and homocysteine metabolism; (3) it's a structural component of cell membranes as phosphatidylcholine; and (4) it's needed for VLDL synthesis in the liver — without it, fat accumulates and you get fatty liver disease. The brain demands are especially high during fetal development, making it critical during pregnancy.

OPTIMAL DOSAGE

Look for: CDP-Choline (Citicoline, Cognizin®) for brain health; Alpha-GPC for sports/nootropic; Phosphatidylcholine for general supplementation
Avoid: Choline bitartrate as sole source for cognitive claims (poor brain bioavailability); proprietary blends
Minimum effective dose: 250mg choline equivalent per day as supplement (food provides the rest)
Third-party tested brands: Jarrow Formulas (Citicoline), NOW Foods (Alpha-GPC, Phosphatidylcholine)
