Beta-Alanine is a beta amino acid that is naturally occurring and that has a name given by the International Union of Pure and Applied Chemistry – IUPAC – sounding as distinctive as 3-aminopropanoic acid. This nonessential amino acid is derived in the body by the degradation of carnosine or dihydrouracil. It is furthermore a part of natural peptides anserine and carnosine and can be found as a component of Vitamin B5, also known as pantothenic acid. Beta-alanine levels limit the amount of carnosine, which means that it is a rate limiting factor for this dipeptide. When beta-alanine is being supplemented, it has been observed that carnosine levels in muscles are raised, which seems to reduce fatigue in athletes and raise the level of exercises that can be done.
