The evidence · BCAAs
What the published reviews of BCAAs concluded
- Branched Chain Amino Acids (BCAAs) and Traumatic Brain Injury: A Systematic Review. · The Journal of head trauma rehabilitation, 2018
“Although our review demonstrates an overall positive association between BCAAs and TBI outcome, the evidence of the efficacy of supplementation has been limited to severe TBI.”
- Branched-Chain Amino Acids and Seizures: A Systematic Review of the Literature. · CNS drugs, 2019
“The contradictory effects of BCAAs on seizure activity likely reflect differences in the complex mechanisms that underlie seizure disorders.”
- Branched-chain amino acids for people with hepatic encephalopathy. · The Cochrane database of systematic reviews, 2017
“In this updated review, we included five additional trials. The analyses showed that BCAA had a beneficial effect on hepatic encephalopathy. We found no effect on mortality, quality of life, or nutritional parameters, but we need additional trials to evaluate these outcomes.”
- Efficacy of branched chain amino acids supplementation in liver cirrhosis: A systematic review and meta-analysis. · Clinical nutrition (Edinburgh, Scotland), 2022
“Supplementation with BCAA seems to improve significant prognostic factors for patients with cirrhosis, with potential positive impact in mortality. Heterogeneity of study findings attributed to many factors limit overall conclusion and results require further assessment.”
Method: PubMed searched in humans for systematic reviews and meta-analyses with BCAAs in the title; these 4 of the 10 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether BCAAs will work for you — each of these reports an average across trials published 2017–2022, and null findings are shown here as readily as positive ones.
How these 5 BCAAs products were ranked
Not one of these 5 BCAAs products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever BCAAs you buy. Full methodology.
