Association of choline and betaine with the risk of cardiovascular disease and all-cause mortality: Meta-analysis
European journal of clinical investigation (2023) · Meta analysis · n=33009
Random-effects model results showed that highest versus lowest quantile of circulating choline concentrations were associated with the risk of CVD (RR = 1.29, 95% CI: 1.04-1.61) and all-cause mortality (RR = 1.62, 95% CI: 1.12-2.36).

Activity of Choline Alphoscerate on Adult-Onset Cognitive Dysfunctions: A Systematic Review and Meta-Analysis
Journal of Alzheimer's disease : JAD (2023) · Meta analysis · n=1326
We found significant effects of α-GPC in combination with donepezil on cognition [4 RCTs, mean difference (MD):1.72, 95% confidence interval (CI): 0.20 to 3.25], functional outcomes [3 RCTs, MD:0.79, 95% CI: 0.34 to 1.23], and behavioral outcomes [4 RCTs; MD: -7.61, 95% CI: -10.31 to -4.91].
Based on meta-analyses showing FPG reduction of 0.59-0.82 mmol/L and HbA1c reduction of 0.63%. Studies primarily used berberine HCl with low bioavailability. Effects require divided doses and may take 8-12 weeks.
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.
