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]).

Ecdysterone and Turkesterone-Compounds with Prominent Potential in Sport and Healthy Nutrition
Nutrients (2024) · Systematic review
The current review investigates the beneficial biological effects of ecdysterone and turkesterone in nutrition, highlighting their roles not only in enhancing athletic performance but also in the management of various health problems.
Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones
International journal of molecular sciences (2022) · Systematic review
In plants, PEs play a potent role in enhancing tolerance against insects and nematodes via their allelochemical activity, which increases plant biological and metabolic responses.
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 limited RCT data showing no group-specific effects in n=28 study. One small study (n=10) showed some promise but very limited sample size. Bioavailability concerns limit effectiveness estimates.
AI-estimated from published studies. Interpret as directional guidance.
BCAAs has a higher evidence score (9/10 vs 8/10) and wins in 2 of 3 categories.
For build strength & muscle, Beta-Ecdysterone has a higher relevance score (70 vs 65).
No known interactions between BCAAs and Beta-Ecdysterone have been documented in our database. However, always consult a healthcare provider before combining supplements.
