| Muscle protein synthesis (MPS)           | Limited/conditional | BCAAs activate anabolic signaling, but sustained MPS requires other EAAs.

| Muscle soreness/damage markers           | Moderate            | Meta-analyses show reduced CK and soreness with BCAA.

| Muscle performance/strength              | Weak/inconsistent   | Some recent studies in older adults suggest benefit; not robustly consistent overall.

| Lean mass preservation in weight loss    | No clear benefit    | 2021 trial showed no lean mass preservation.
