BCAA 5000 is NutraBio's anabolic matrix that combines the powerful muscle regenerating benefits of branched chain amino acids (BCAAs). Collectively made up of leucine, isoleucine, and valine, BCAAs are known as essential amino acids because the human body cannot produce them and they must be consumed through diet or supplementation. Independently, each BCAA plays an important physiological role in the body. However, it is their synergistic combination that produces one of the most important processes involved in muscle building and recovery—muscle protein synthesis (MPS).
