Plain answer: eggs do not contain citicoline (CDP-choline) as such—citicoline is primarily a supplemental/pharmaceutical compound. However, eggs are rich in choline, a key nutrient used to make acetylcholine and membrane phospholipids.\n\nA large egg typically provides roughly 100+ mg of choline (values vary by database and egg size). That is why eggs, liver, fish, meat, dairy, and some legumes are practical dietary sources to support choline status.\n\nCholine intake is not the same as taking citicoline. Citicoline provides choline plus cytidine and may support membrane metabolism via different pathways. For cognitive goals, nutrition is only one pillar—sleep, metabolic health, omega-3 intake, exercise, and stress management often deliver larger benefits.\n\nBottom line: no citicoline in eggs, but meaningful choline.
