Is Citicoline Effective in Preventing and Slowing Down Dementia?-A Systematic Review and a Meta-Analysis
Nutrients (2023) · Meta analysis
Systematic review of 7 studies published 2010 to 2022 in people with mild cognitive impairment, Alzheimer's disease or post-stroke dementia, 6 of them pooled in a meta-analysis.
Application of Citicoline in Neurological Disorders: A Systematic Review
Nutrients (2020) · Systematic review
In an animal model of nerve damage and neuropathy, citicoline stimulated regeneration and lessened pain.

Positive effects on memory
Antenatal dietary supplementation with myo-inositol for preventing gestational diabetes
The Cochrane database of systematic reviews (2023) · Meta analysis · n=1319
For the primary neonatal outcomes, only one study measured the risk of a large-for-gestational-age infant and found myo-inositol was associated with both appreciable benefit and harm (RR 1.40, 95% CI 0.65 to 3.02; 1 study, 234 infants; low-certainty evidence).
Inositol Nutritional Supplementation for the Prevention of Gestational Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Nutrients (2022) · Meta analysis · n=1321
Pooled results were expressed as relative risk (RR) or mean difference (MD) with a 95% confidence interval (95% CI).
Antioxidants for female subfertility
The Cochrane database of systematic reviews (2020) · Meta analysis · n=7760
Due to the very low-quality of the evidence we are uncertain whether antioxidants improve live birth rate compared with placebo or no treatment/standard treatment (odds ratio (OR) 1.81, 95% confidence interval (CI) 1.36 to 2.43; P < 0.001, I2 = 29%; 13 RCTs, 1227 women).
At 500 mg a day for 12 weeks, a randomised placebo-controlled trial in 100 healthy older adults with age-associated memory impairment found greater gains in episodic and composite memory (PMID 33978188). A 4-week controlled trial in 24 older adults with memory deficits gave 500 or 1,000 mg a day and found similar free-recall gains in both groups, so the curve is flat from 500 to 1,000 mg (PMID 9203170). At 1 g a day for 12 months, an open-label randomised trial in 347 people after a first ischaemic stroke found better attention-executive function and temporal orientation than usual care (PMID 23406981). The 2,000 mg ceiling is a 12-week placebo-controlled trial in 62 adults with alcohol use disorder, where citicoline titrated to 2,000 mg a day was well tolerated but did not change cognitive measures (PMID 30457668). The dementia meta-analysis (PMID 36678257) found improved cognitive status in studies of poor quality and gives no doses. No trial found a better dose than 500 mg, so no optimal dose is set.
