beta-Alanine

What is beta-alanine?

Beta-alanine, also called β-alanine, is a naturally occurring beta amino acid. This means it's a building block for proteins, but unlike most amino acids, the amino group (the part that makes it an amino acid) is attached to the second carbon atom (the beta carbon) instead of the first (alpha carbon) like in standard amino acids like alanine.

What does beta-alanine do?

In the body, beta-alanine is a precursor for carnosine, a molecule that helps muscles buffer lactic acid buildup during exercise. By increasing carnosine levels, beta-alanine supplementation may reduce fatigue and improve athletic performance.

Other properties of beta-alanine:

• Beta-alanine is produced by the body when it breaks down uracil (a component of RNA) and carnosine.
• It may act as a weak neurotransmitter.
• Beta-alanine is generally considered safe for short-term use when taken by mouth in appropriate doses.

Where can I find beta-alanine?

Beta-alanine is found naturally in some foods like chicken, fish, and meat. It's also available as a dietary supplement.
