What is Beta-Alanine?

Beta-alanine is a naturally occurring non-essential amino acid found in foods like meat and fish. It plays a significant role in the synthesis of carnosine, a compound that helps buffer acid in muscles, potentially enhancing physical performance. The most studied health effect of beta-alanine supplementation is its ability to improve exercise performance, particularly in high-intensity exercises, by delaying the onset of muscle fatigue. Research indicates that beta-alanine can increase carnosine
