CDP-choline (citicoline)
Cognitive · Choline precursor / membrane substrate
Tier B+
Bottom line
Read Off Label grades CDP-choline (citicoline) as B+ (7.1/10) based on moderate evidence, med benefit magnitude, and a low-risk safety profile.
Japanese and European clinical use for post-stroke cognition and vascular dementia.
Studied, labeled, or reported-use context: 250-2000 mg/day PO divided — Rx in EU, Asia; OTC in US; not individualized guidance.
What the evidence says
Japanese and European clinical use for post-stroke cognition and vascular dementia. IDEALE and COBRIT trials mixed. Generally better tolerated than Alpha-GPC and may carry less TMAO concern due to cytidine content.
Mechanism
Cytidine diphosphate-choline; Kennedy pathway intermediate for phosphatidylcholine synthesis; yields both choline (ACh precursor) and cytidine (converted to uridine; supports membrane biogenesis)
Studied, labeled, or reported dose & route
250-2000 mg/day PO divided
This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
