Gen-Tec Nutraceuticals source, blend and package 100 percent pure pharmaceutical grade laboratory tested (HPLC) free from Branched chain amino acid powder. BCAA's can be used by anyone engaging in intensive exercise. Our amino acids are naturally fermented from seed and plant material via an 18 stage patented process. This process guarantees our product to be of a premium standard, free of impurities. BCAA's are comprised of three essential amino acids, L-leucine, Lisoleucine and L-valine. They are essential for building and maintaining muscles and work by facilitating the synthesis of proteins in the body. They account for about 1/3 of muscle protein and can be used directly by the muscles for energy. BCAAs are needed during times of physical stress, so are often used as bodybuilding and athletic supplements. Preliminary evidence suggests that BCAA supplementation prior to exercise may help prevent muscle protein breakdown and improve recovery time after strenuous workouts. Most studies suggest the need for a high L-leucine content as this is the predominant amino broken down during bouts of intense exercise. The Gen-Tec BCAA ratios are 80 percent leucine, 10 percent isoleucine and 10 percent valine. Available in 200 g jar.
