Bpi sports' best bcaa is the first to bond the three branched chain amino acids - leucine, isoleucine and valine - utilizing a proprietary process route, to form oligiopeptides (a bonded chain of amino acids; for example, a peptide linked chain). The oligiopeptide-based branched chain amino acids may act as a better transport vehicle, allowing for more efficient metabolization, greater bio-activity, enhanced onset time, and a generally improved bcaa model. And, the scientific minds at bpi sports didn't stop here . The science of oligiopeptide chains has been emerging for decades. And, in recent years thought-leading researchers have increasingly come to the consensus that in this form, protein nutrition, bio-availability, stability, solubility, and transport, among many key factors, can all be resolved.
