Leucine The Big Player In BCAAs

You're very well aware that the Branched Chain Amino Acids Leucine, Isoleucine and Valine serve as building blocks of lean mass. Several recent studies point to Leucine as the primary mover in this small but very important group of synergistic amino acids. It was reported in the Journal of Molecular Reproduction and Development that Leucine not only stimulates protein synthesis by triggering skeletal muscle mTOR signaling, but also activates satellite cell activity which is the starting point of muscle fiber hypertrophy. In addition, Leucine plays a role in weight loss by increasing energy expenditure and decreasing adiposity (fat storage).

The Bigger Picture: Starting with the basics, or in this case the building blocks, is always a great way to achieve ambitious goals. There are many quality supplements that contain ample quantities of Leucine including protein powders as well as BCAA caps and powders. Of course, it's important to remember that supplements are just that; supplemental to a balanced diet of nutritious whole foods. And don't forget regular exercise. You can't build a better body without putting in the work.
