New horizons for the study of saffron (Crocus sativus L.) and its active ingredients in the management of neurological and psychiatric disorders: A systematic review of clinical evidence and mechanisms
Phytotherapy research : PTR (2024) · Systematic review
A random-effects or fixed-effects model was used to calculate the pooled effect sizes.
Based on meta-analysis of α-GPC with donepezil showing cognitive benefits and citicoline studies. Effects vary significantly by choline form - α-GPC and CDP-choline show higher bioavailability. Most evidence is in older adults or those with existing cognitive impairment.
Based on meta-analysis of 11 RCTs (n=531) showing significant antidepressant effects vs placebo with large effect size (Hedges g = 0.99). 30mg daily was most commonly effective dose. Conservative effectiveness estimates given study heterogeneity and modest sample sizes in individual trials.
