What is citicoline (CDP-Choline)?

Citicoline, also called CDP-Choline, is a choline-containing compound used as a dietary supplement. It serves as a precursor for phosphatidylcholine and acetylcholine, supporting cell membranes and neurotransmitter function.

What are the potential benefits of citicoline?

Citicoline is commonly used to support memory, attention, and mental processing, particularly in mild cognitive impairment or during recovery after stroke. It is also used as an adjunct in glaucoma to support retinal and visual function.

What is a typical citicoline dosage?

Common supplemental doses range from 250 to 1000 mg per day. The best dose can vary by goal, product form, and individual tolerance.

Is citicoline safe and what side effects can occur?

Citicoline is generally well tolerated for many people, but side effects can include headache, gastrointestinal upset, or sleep changes. People who are pregnant, breastfeeding, or taking medications should consult a clinician before use.

Description

Citicoline, also called CDP-Choline, is a choline compound used as a dietary supplement for cognitive and neuroprotective purposes. It is a precursor to phosphatidylcholine and acetylcholine, supporting cell membranes and neurotransmitter function.

benefits

Main effects with level of evidence

Moderate

Note on evidence

Evidence for cognitive benefits and neuroprotection is strongest in populations with neurological impairment, with mixed but promising results in healthy adults.

Cognitive Enhancement

Moderate

Supplementation may improve memory, attention, and mental processing—especially in individuals with mild cognitive impairment or recovering from stroke.

Particularly relevant for: Older adults · Individuals with cognitive impairment · Post-stroke patients

1 · Citicoline improves cognitive performance in patients with chronic cerebral disorders: a meta-analysis 2 · Citicoline in acute ischemic stroke: a systematic review and meta-analysis

Support in Stroke Recovery

Moderate

May aid neurological and functional recovery when used early after ischemic stroke, as an adjunct to standard therapy.

Particularly relevant for: Post-stroke patients

2 · Citicoline in acute ischemic stroke: a systematic review and meta-analysis 6 · Citicoline: update on a neuroprotective agent

Neuroprotection in Glaucoma

Limited

May help slow progression of visual field loss and improve retinal function in glaucoma, especially as adjunctive therapy.

Particularly relevant for: Adults with glaucoma

3 · Neuroprotective effects of citicoline in glaucoma patients

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Citicoline is generally well-tolerated, but rare side effects and limited data in pregnancy and certain populations warrant caution.

warning notices

Mild side effects may include headache, insomnia, or gastrointestinal discomfort.
Monitor for hypotension, particularly if predisposed.
Safety not established in pregnancy or breastfeeding; avoid unless recommended by a healthcare provider.
Allergic reactions are rare but possible.
Avoid use if hypersensitive to citicoline or its components.
Use only with clinician supervision in pregnancy or breastfeeding due to limited safety data.
Monitor blood pressure if you have a history of hypotension.
Use caution if taking dopaminergic medications (e.g., levodopa), as citicoline may amplify their effects.
