Beta-alanine is a naturally occurring non-essential amino acid that is produced naturally in the body. Beta-alanine has been identified as the rate-limiting precursor to carnosine synthesis and has been consistently shown to increase levels of carnosine in human skeletal muscle1
Beta-alanine has been identified as the rate-limiting precursor to carnosine synthesis. Carnosine acts as a buffer for the lactic acid produced during high-intensity exercises, and helps delay the onset of neuromuscular fatigue1. β-alanine supplementation can increase exercise and cognitive performance2
Single large boluses of beta-alanine have been shown to induce paraesthesia (i.e. tingling), and have not been effective for performance outcomes.
