Proteins consist of chains of amino acids in various lenght and composition. The human body uses a total of approximately 25 different amino acids for the production of the proteins used for the building of tissue, the production of hormones, enzymes, and various blood cells etc. Protein constitutes about 25% of our body weight.
About 2/3 of these 25 amino acids the body produces by means of the other amino acids; the last 1/3, however, must be supplied through the diet. These are therefore called essential and are vital just like certain vitamins, minerals, and fatty acids. They are isoleucine, lysine, methionine, phenylalanine, threonine, tryptophane, and valine.
A supply of amino acid complexes containing the eight essential amino acids function as an easily absorbable protein supplement since the body doesn't have to break down and transform the proteins into its basic components, the amino acids.
