You also might find branched-chain amino acids, a.k.a. leucine, isoleucine, and valine, which all have a similar chemical structure and are the three most important aminos for building muscle.

The supplement contains all 9 essential amino acids and all branched-chain amino acids, which are required for many bodily processes such as building proteins and synthesizing neurotransmitters.
