what is beta alanine

β-Alanine, also known as beta-alanine, is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon instead of the more usual α-carbon for alanine. The IUPAC name for β-alanine is 3-aminopropanoic acid. Unlike its counterpart α-alanine, β-alanine has no stereocenter. It is a non-essential amino acid that is produced naturally in the body and is used to make other chemicals in the body. β-Alanine aids in the production of carnosine, a compound that plays a role in muscle endurance in high-intensity exercise. It is a component of the peptides carnosine and anserine and also of pantothenic acid (vitamin B5), which itself is a component of coenzyme A. β-Alanine is metabolized into acetic acid and is the rate-limiting precursor of carnosine. Supplementation with β-alanine has been shown to increase the concentration of carnosine in muscles, decrease fatigue in athletes, and increase total muscular work done. It can improve exercise performance and boost overall health, especially for athletes and fitness enthusiasts. However, its important to consult with a healthcare provider before taking β-alanine supplements, as standard doses have not been established and the quality and active ingredients in supplements may vary widely from maker to maker.
