Micronutrients & recovery
BCAA supplementation may attenuate muscle soreness and recovery decrements in resistance-trained athletes, but effects are inconsistent in endurance sports.
If you do heavy resistance training, BCAAs might help slightly with muscle soreness, but the evidence is not strong enough to recommend them as a primary recovery tool. Focus on post-workout meals with complete protein. For endurance athletes, BCAAs do not consistently help with recovery or soreness.
ModerateQualifiesMEDIUM confidence
Studies that included resistance participants showed that BCAAs attenuated muscle soreness after exercise, while in endurance sports the findings were inconsistent.
Why this rating
Based on systematic review, but heterogeneity in soreness assessment and resistance training protocols reduces certainty.

- Oral branched-chain amino acid (BCAA) supplementation provides negligible benefits for athletic performance and body composition in trained athletes, regardless of supplementation duration or dosage.Good
- BCAA supplementation activates anabolic signaling pathways (mTORC1) and improves hormonal profiles (testosterone/cortisol ratio) in the short term, but this does not translate to long-term muscle or strength gains if total protein intake is adequate.Good
