Leucine, Isoleucine and Valine belong to the family of protein building Branched-Chain Amino Acids (BCAAs). They are among the 9 essential aminos for humans, because our bodies can’t manufacture them, so their only source is our daily food or food supplementation. BCAAs account for 35% of the essential amino acids in muscle proteins. On the other hand, Glutamine is a top ingredient for athletes in popularity, so we included it to boost Glutamine intake levels. As a plus, BCAA+GLUTAMINE XPRESS is fortied with Taurine as well! The 1:1 combination of high dose BCAAs and Glutamine in this scientifically formulated powder promotes muscle recovery during and after high-intensity workouts preventing undesirable muscle breakdown and performance decrease.
