The Branched-Chain Amino Acids (BCAA's) are an important group of essential amino acids consisting of Leucine, Isoleucine and Valine. The BCAA's are among the nine essential amino acids for humans, because our body can’t manufacture them. Their only source is our daily food or food supplementation. On the other hand, they account for 35% of the essential amino acids in muscle proteins. Leucine, Isoleucine and Valine are indispensable amino acids provided by mixed dietary protein intakes from different sources. BCAA's can also be consumed as food supplements, especially suggested around intense workouts or physical work. BCAA XPRESS contains a 2:1:1 ratio of Leucine, Isoleucine and Valine; and because it is in a powder-drink form, as a liquid, it can absorb faster than a tablet formula. Also, it can conveniently sipped during a workout.
