Why do athletes take branched-chain amino acids (BCAAs)?

ANSWER

Athletes may take oral supplements of branched-chain amino acids (BCAAs) to try to help with recovery from workouts and enhance athletic performance.

Studies suggest that BCAAs may prevent muscle breakdown during exercise, but they aren't likely to help with athletic performance.
