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).

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.

Dietary Supplementation With NAD+-Boosting Compounds in Humans: Current Knowledge and Future Directions
The journals of gerontology. Series A, Biological sciences and medical sciences (2023) · Systematic review
Limitations are identified and future research directions are suggested to further our understanding of the potential efficacy of NAD+-boosting compounds for improving physiological function and extending human health span.© The Author(s) 2023.
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 RCT with n=111 NAFLD patients showing reduced hepatic inflammation markers and ceramide 14:0 levels. Conservative estimate given single study and disease-specific population.
AI-estimated from published studies. Interpret as directional guidance.
Choline has a higher evidence score (9/10 vs 7/10) and wins in 2 of 3 categories.
For reduce inflammation, Choline has a higher relevance score (85 vs 50).
