topicBranched Chain Amino Acid Supplementation Exercise Recovery Meta-Analysis
claimBranched-chain amino acids (BCAAs) are an increasingly popular sports supplement used by athletes as they are advertised to increase endurance, muscle recovery, lean muscle mass, and decrease muscle soreness and fatigue.

claimHowever, this can also lead to the production of BCAA-derived metabolites and potentially contribute to a state known as “anabolic resistance,” characterized by diminished muscle protein synthesis and a reduced adaptive response to training, often linked with chronic fatigue, inflammation, or dysregulated protein turnover.
