What systematic reviews concluded
Outcomes that systematic reviews of Choline reached a verdict on: 2 with a benefit, 1 with no effect, 3 unclear. Each is quoted from a review and linked to it on PubMed. How these were read.
Reviews found a benefit (2)
“The inclusion of a highly effective drug in the specialized medical care system will ensure the availability of cognitive impairment treatment programs and improve patients' quality of life.” PMID 41362980
“It also enhances cognitive functions among healthy individuals and improves prognosis after stroke.” PMID 33053828
Reviews found no effect (1)
“current evidence does not support citicoline or PS-containing compounds as effective cognitive enhancers in mental disorders” PMID 42538853
Not enough to say: cognitive function in healthy adults; breast milk choline content; dna methylation.
