Researched for: phospholipid synthesis and cognitive function
Also known as: CDP-Choline
Citicoline is cytidine diphosphate choline and is metabolized to choline and cytidine-related products after administration. Human research includes oral and parenteral formulations. A randomized trial in healthy older adults used 500 mg/day for 12 weeks; this does not establish a universal cognitive benefit or make retail supplements equivalent to drug formulations used outside the United States.
Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.
Data source: Randomized human trial plus current supplement and reagent catalogs
Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Amounts and schedules are separated by administration route. Evidence badges distinguish labels, human studies, preclinical work, community reports, and evidence gaps.
500 mg once daily
Context: randomized placebo-controlled trial PMID 33978188
Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.
Route safety: Research-study protocol only; it is not an approved or individualized instruction and should not be extrapolated to another route.
No route-specific amount established in the reviewed record.
Context: The catalog identifies this route, but its reviewed sources do not establish a separate amount and schedule for it.
Formulation: Route-specific sterile formulation and professional handling requirements apply; concentration cannot be inferred from an oral or topical product.
Route safety: No route-specific protocol is established. Do not infer an amount from another route, component, or formulation.
Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.
Current products include 250 mg capsules and 30 g powder; laboratory citicoline sodium is also sold in 1-10 g packs. Community reports of stimulation or insomnia are anecdotal.
Supplementary research context only. Not medical advice or a treatment recommendation.
