Fatty liver reexamined choline and mitochondrial toxin amelioration

Table 3 Comparative pharmacokinetics and safety profile of citicoline vs α-glycerophosphocholine

Metric	Citicoline	α-GPC	Key takeaway
Elemental choline	18%-19%	40%-41%	α-GPC more choline-dense
Oral bioavailability	Approximately 95%	Approximately 85%	Both excellent
Peak plasma free choline (500 mg eq)	↑2.6-fold vs baseline[10]	↑1.8 fold vs baseline[86]	Citicoline faster spike
Effect on hepatic PC/PE	↑PC + PE balance[85]	↑PC preferentially[86]	Citicoline broader scope
TMAO production	Minimal[80]	Moderate↑[87]	Clinically relevant
Long-term vascular signal	Neutral (no association)	+46% 10 years stroke risk[9]	Use cautiously

PC/PE: Phosphatidylcholine/phosphatidylethanolamine; TMAO: Trimethylamine-Noxide; α-GPC: Αglycerophosphocholine.
