The evidence in words
Safety profile
Safe; largely a waste of money if protein intake is adequate.
Interactions to respect
No major interactions are on record for BCAAs at typical doses, but tell your clinician about everything you take.
What BCAAs is
Branched-chain amino acids (leucine, isoleucine, valine) are marketed for muscle growth and recovery.
The honest bottom line
Skip them if you eat enough protein — whole protein or EAAs beat BCAAs. Marginal niche in fasted training only.
