Amino acids
Amino acids play an important role in most body processes. Any physical activity that requires energy such as movement, recovery, muscle/strength gain and fat burning, even mood and brain function are critically dependent on amino acids. Of the 24 known amino acids, nine are considered essential: leucine, isoleucine, valine, methionine, threonine, lysine, phenylalanine, tryptophan, and histidine. If even one of them is absent or lacking, protein synthesis is weakened or stopped. This is especially important for athletes - the process of building new muscles is simply impossible without amino acids.
