First of all BCAA (short form for branched chain amino acids) are essential for humans, what means that they have to be consumed with your nutrition and cannot be created in your body. In contrast to all other amino acids BCAA are metabolized directly and not indirectly thru the liver. That means they go straight into the muscle cells. Furthermore BCAA represent the highest amount of amino acids in muscle tissue. This means you take BCAA directly after training to speed up the muscle building process. The tablets can be easily portioned and swallowed.
