Branch Chain Amino Acids or BCAAs are the most rapidly absorbed of all amino acids 70 of BCAAs immediately pass through the liver & are 'pushed' into muscle tissue where the majority of the metabolism takes place. BCAAs are also responsible for muscle production & energy production. Muscle production is supplied by an increase in protein synthesis. Energy production is caused when BCAAs assist in the production of Lalanine a primary pathway to muscle energy causing both increased prot
