Beta-alanine is a non-essential amino acid obtained through protein foods such as chicken, beef, pork, fish and it naturally occurs in the body. Recently (2003) researchers have been studying Beta-Alanine examining its effects on exercise performance and lean muscle mass. The man behind the initial studies on Beta-Alanine, Dr. Roger Harris, is the same man that brought creatine to the bodybuilding world. With authorities; such as, Dr. Harris and esteemed research scientists Dr. Jeff Stout and Dr. Mark Tallon publishing research on Beta-Alanine and backing its use as a performance enhancement supplement, the research and bodybuilding communities are taking notice. Although the support of Doctors of this caliber speaks volumes about the efficacy of Beta-Alanine, the science itself is even more impressive.
