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
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].
The bile acid TUDCA and neurodegenerative disorders: An overview
Life sciences (2021) · Review
The tauroursodeoxycholic acid (TUDCA), one of the acids found in bear bile, is a hydrophilic bile acid and naturally produced in the liver by conjugation of taurine to ursodeoxycholic acid (UDCA).
Nutraceutical, Dietary, and Lifestyle Options for Prevention and Treatment of Ventricular Hypertrophy and Heart Failure

The potential advantages of whole-food plant-based diets, moderation in salt intake, avoidance of phosphate additives, and regular exercise training and sauna sessions are also discussed.
Trial of Sodium Phenylbutyrate-Taurursodiol for Amyotrophic Lateral Sclerosis
The New England Journal of Medicine (2020) · Rct · n=137
A phase 2 trial of a combination drug: sodium phenylbutyrate 3 g plus taurursodiol (TUDCA) 1 g. 137 people with ALS were randomly assigned 2:1 to the combination (89) or placebo (48) for 24 weeks.
Choline has a higher evidence score (6/10 vs 6/10) and wins in 1 of 3 categories.
For liver health, TUDCA has a higher relevance score (80 vs 65).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
Weight loss is the real treatment; vitamin E/omega-3 have some evidence, milk thistle modest, TUDCA thin.
