MET-Rx® BCAA 5000 powder supplies a precise, clinically studied ratio of leucine, valine and isoleucine (45/30/25). Branched chain amino acids may be the most important amino acids for exercise and recovery as they work directly within muscle to regulate protein synthesis at the genetic level.* BCAAs can also increase nitrogen retention and can be used as an energy source to fuel exercise.*
