?-Alanine (or beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is at the ?-position from the carboxylate group (i.e., two atoms away, see Figure 1). The IUPAC name for ?-alanine is 3-aminopropanoic acid. Unlike its counterpart ?-alanine, ?-alanine has no stereocenter.
?-Alanine is not used in the biosynthesis of any major proteins or enzymes. It is formed in vivo by the degradation of dihydrouracil and carnosine. It is a component of the naturally occurring peptides carnosine and anserine and also of pantothenic acid (vitamin B5), which itself is a component of coenzyme A. Under normal conditions, ?-alanine is metabolizedinto acetic acid.
?-Alanine is the rate-limiting precursor of carnosine, which is to say carnosine levels are limited by the amount of available ?-alanine. Supplementation with ?-alanine has been shown to increase the concentration of carnosine in muscles, decrease fatigue in athletes and increase total muscular work done.
Typically, studies have used supplementing strategies of multiple doses of 400 mg or 800 mg, administered at regular intervals for up to eight hours, over periods ranging from 4 to 10 weeks. After a 10-week supplementing strategy, the reported increase in intramuscular carnosine content was an average of 80.1% (range 18 to 205%).
A study conducted at Adams State College, Alamosa, Colorado, compared the effects of ?-alanine to a placebo group in two sports: wrestling and American football. The subjects taking ?-alanine achieved more desirable results on all tests compared to placebo. The wrestlers, both placebo and supplement lost weight; however, the supplement group increased lean mass by 1.1 lb., while the placebo group lost lean mass (-0.98 lb). Both American football groups gained weight; however, the supplement group gained an average 2.1 lb lean mass compared to 1.1 lb for placebo
