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).
Higher dietary choline intake is associated with increased risk of all-cause and cause-specific mortality: A systematic review and dose-response meta-analysis of cohort studies
Nutrition research (New York, N.Y.) (2024) · Meta analysis · n=482778
This study showed that each 100 mg/day increment in choline consumption was significantly associated with a 6% and 11% higher risk of all-cause and cardiovascular disease mortality respectively.
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-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.
