Amino acids are a vital part of life. These tiny building blocks allow us to create all types of vital compounds and structures in our body. Amino acids are the foundation of proteins such as muscle, and without them many vital processes can go awry. Amino acids come in two varieties; essential amino acids and non-essential amino acids. There are several subclasses within these two categories, but basically they are divided as amino acids our body can make for itself and those it must get from dietary sources. Protein powders are essential means of providing ample amino acid compounds.
