Acetylcholine building block (mechanism)
Choline is the precursor of acetylcholine, a neurotransmitter for memory, mood and muscle control. Observational studies link higher choline intake to better memory in adults, but a systematic review found choline supplements did not clearly improve cognition in healthy adults. The clearest trial result is developmental, from maternal intake in pregnancy.
Prenatal brain development
In a randomized, double-blind controlled feeding trial in 26 pregnant women, infants of mothers eating 930 mg rather than 480 mg of choline a day in the third trimester had faster information-processing speed over their first year. The trial was small. The Adequate Intake in pregnancy is 450 mg a day, and prenatal supplements typically contain little choline.
Liver fat export: a required nutrient
The liver needs choline, as phosphatidylcholine, to export fat. In a controlled feeding study of 57 adults, a diet with under 50 mg choline a day caused fatty liver or muscle damage in 77% of men and 80% of postmenopausal women but 44% of premenopausal women, and organ function recovered when choline was restored. Trials of extra choline for liver health in well-fed people are lacking.
Mechanism of action
Acetylcholine synthesis
Choline supplies the raw material for acetylcholine, the neurotransmitter used in memory, attention, and muscle control.
Phospholipid and methyl-donor roles
Choline builds phosphatidylcholine for cell membranes and is a source of methyl groups needed for many steps in metabolism.
Clinical trials
Randomized, double-blind, controlled feeding study of maternal choline intake in the third trimester (Caudill et al. 2018, FASEB J).
26 pregnant women randomized to 480 or 930 mg choline a day from the third trimester to delivery; 24 infants tested at 4, 7, 10 and 13 months.
Mean reaction time averaged across the four ages was significantly faster for infants of mothers in the 930 mg group. This is a small trial of total choline intake with an infant outcome, not evidence for adult memory or for VitaCholine specifically. Funded in part by the Egg Nutrition Center and the Beef Checkoff.
