BPI Sports has been making the best-tasting amino acid products for 10 years. Our award-winning formula, Best BCAA, is powered by 5g of branched-chain amino acids (BCAAs) and conjugated linoleic acid (CLA) to support muscle growth, fat loss, athletic performance, and recovery. The three BCAAs are leucine, isoleucine, and valine. These three amino acids play a particularly important role in muscle growth by both stimulating protein synthesis and preventing protein catabolism. No matter what goal you're working towards, you can count on Best BCAA to help you get there. The hardest part will be choosing between all the delicious flavors.
