Best BCAA is a branched chain amino acid (BCAA) supplement that utilizes Oligopeptide-Enzymatic Technology. This is a bonded chain of three key amino acids: leucine, isoleucine and valine, which may act as a better transport vehicle for optimal absorption. Best BCAA supports lean muscle growth, recovery and helps prevent muscle catabolism. Take one scoop before your workout to help improve performance, one scoop during your workout to help burn fat and preserve muscle, and/or one scoop after your workout to accelerate recovery. If the benefits aren't enough to convince you, Best BCAA has also received the ChromaDex Quality Verified Seal, an easy-to-spot emblem on the label that signifies the rigorous, third-party testing each bottle goes through to ensure it is of the highest quality possible.
