Systematic review with meta-analysis: Branched-chain amino acid supplementation in liver disease
European journal of clinical investigation (2023) · Meta analysis · n=2308
According to meta-analyses, long-term (at least 6 months) BCAA supplementation in cirrhotic patients significantly improved event-free survival (p = .008; RR .61 95% CI .42-.88) and tended to improve overall survival (p = .05; RR .58 95% CI .34-1.00).
Branched-chain amino acids for people with hepatic encephalopathy
The Cochrane database of systematic reviews (2017) · Meta analysis · n=827
In a random-effects meta-analysis of mortality, we found no difference between BCAA and controls (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.69 to 1.11; 760 participants; 15 trials; moderate quality of evidence).
Causal Relationship Between Branched-Chain Amino Acids and Hypertension: A Mendelian Randomization Study
Journal of the American Heart Association (2024) · Meta analysis · n=845
As suggested by the meta-analysis results, elevated BCAA levels were associated with a higher risk of hypertension (isoleucine: summary odds ratio, 1.26 [95% CI, 1.08-1.47]; leucine: summary odds ratio, 1.28 [95% CI, 1.07-1.52]; valine: summary odds ratio, 1.32 [95% CI, 1.12-1.57]).

AMPA Receptor Modulation Through Medium-Chain Triglycerides and Decanoic Acid Supports Nutritional Intervention in Pediatric Epilepsy
Nutrients (2025) · Systematic review
Methods: A systematic review was conducted, including articles from January 2000 to January 2025, to explore the potential role of medium-chain triglyceride (MCT) add-on to classic KD and as MCT supplementation in free diets in the management of pediatric drug-resistant epilepsy (DRE).
Influence of Carbohydrate Intake on Caprylic Acid (C8:0)-Induced Ketogenesis-A Systematic Review and Meta-Analysis
Nutrients (2024) · Meta analysis
Forest plot analysis showed heterogeneous data.
Evidence limited to resistance training populations. Systematic review found negligible benefits on body composition in athletes. Benefits may be more apparent in caloric deficit or fasted states but data is limited.
Based on meta-analysis of 291 participants showing MCT decreases energy intake. Effect magnitude limited by small study sizes and heterogeneous methodology. GI tolerance varies significantly between individuals.
AI-estimated from published studies. Interpret as directional guidance.
