Beta-alanine is an amino acid found within skeletal muscle. When combined with histidine, it forms the dipeptide carnosine. Beta-alanine is a type of amino acid that isn't involved in synthesizing proteins (i.e., building muscle). Rather, it is responsible for increasing the buffering capabilities of the body.
