Alanine is an amino acid found within skeletal muscle. It's a non-essential amino acid in which the amino group is at the beta-position from the carboxylate group. It is naturally produced in the body and is listed as one of the supplements that can directly improve sports performance by the International Olympic Committee. Unlike most amino acids, Beta Alanine is not used by the body to synthesize proteins. Instead, it performs as a rate-limiting precursor to the synthesis of Carnosine.
