Citicoline (CDP-Choline)
Supplies raw material for the brain’s focus messenger — attention is the most plausible target.
Say that in clinical terms
Same acetylcholine/membrane-building mechanism as above; attention and processing speed are the cognitive domains most plausibly linked to it acutely.
How strong is the research?
No Benefit evidence
Pooled trials showed some benefit for memory, but not for attention specifically.
Industry fundedLow-quality evidence
2 papers read, 1 against.
Tested as: citicoline 250-500 mg/day for 28 days in healthy women 40-60 (attention only); pooled data mostly from elderly patients with diagnosed chronic cerebral disease, not healthy adults with everyday mental fatigue
How much to take
250–500 mg
