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]).
Efficacy and Safety of Coenzyme Q10 Supplementation in the Treatment of Polycystic Ovary Syndrome: a Systematic Review and Meta-analysis
Reproductive sciences (Thousand Oaks, Calif.) (2023) · Meta analysis · n=1021
Only one RCT reported adverse events, and they found that patients had no adverse effects or symptoms following supplementation.
Coenzyme Q10 for heart failure
The Cochrane database of systematic reviews (2021) · Meta analysis · n=1573
Coenzyme Q10 probably reduces the risk of all-cause mortality more than control (RR 0.58, 95% CI 0.35 to 0.95; 1 study, 420 participants; number needed to treat for an additional beneficial outcome (NNTB) 13.3; moderate-quality evidence).
Antioxidants for female subfertility
The Cochrane database of systematic reviews (2017) · Meta analysis · n=6510
This suggests that among subfertile women with an expected clinical pregnancy rate of 22%, the rate among women using antioxidants would be between 27% and 33%.
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 heart failure meta-analysis (n=1573) showing mortality reduction. Effectiveness conservative due to single primary study (n=420). Take with food to reduce GI upset. Ubiquinol forms may have better absorption.
AI-estimated from published studies. Interpret as directional guidance.
