The BCAA Blend: L-Leucine, L-Valine, and L-IsoLeucine These three nutrients are classified as essential branched chain amino acids because the body cannot produce them; they must be obtained from food or supplementation. These BCAAs all work in conjunction with each other to aid in protein synthesis and muscle recovery. L-Valine is essential for energy conversion and from that, the L-Leucine plays a vital role in the generation of muscle tissue. L-Isoleucine can increase glucose tolerance and improve insulin health. This amino triad helps promote fat metabolism while at the same time preventing muscle catabolism, or breakdown, to aid an athlete in achieving a lean physique. They are an integral part of Intracell 7 due to their significant role in muscle hypertrophy to increase strength and mass. Moreover, when ingested with the fast absorbing cyclic dextrin these BCAAs reach the muscle rapidly to begin the process of protein synthesis.
