What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Citicoline is an other most often used for memory, focus and attention, brain phospholipid synthesis. NutriStack rates the overall evidence as moderate. A typical adult dose is 250–500 mg daily, commonly taken as citicoline (cdp-choline), cognizin is a patented, well-studied form. This profile indexes 18 sources.
The bottom line
Evidence rating moderate. Most-documented uses: memory, focus and attention, brain phospholipid synthesis. 18 sources indexed (2002–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Hydrolyzed to choline and cytidine. Choline is acetylated to acetylcholine (learning, memory, attention). Cytidine converts to uridine, which is incorporated into CDP-choline pathway for phosphatidylcholine synthesis (cell membrane component). Increases dopamine receptor density in frontal cortex.1
Dosing & protocol.
Take in the morning for cognitive enhancement; can be stimulating9
What it actually costs.
Real-world pricing across three quality tiers. Assumes CDP-Choline / Cognizin.
Assumes 250-500 mg/day. Vendor basis: NOW/iHerb, Vitacost, Life Extension, and Amazon marketplace; Cognizin-branded products drive premium pricing. Updated 2026-05-28.
The same dose, as food.
How much you'd eat to match a supplemental dose.
Citicoline is a supplemental CDP-choline form; foods support choline intake through other phospholipids.
