Key Benefits MUSCLE GROWTH: Branched-chain amino acids (BCAAs) are the building blocks of protein. As such, they play an integral role in the growth, maintenance and repair of muscle. WEIGHT LOSS: Best BCAA™ contains a conjugated linoleic acid (CLA) matrix. CLA helps to support muscle growth, which boosts metabolism, and may help prevent fat storage. PERFORMANCE: Our potent BCAA powder boosts endurance levels for improved athletic performance – on the field, on the court, or in the gym. RECOVERY: BCAAs help repair and rebuild muscle to aid in post-workout recovery. This may help reduce soreness.
