β-Alanine is a non-proteinogenic amino acid and a direct precursor of carnosine. Its supplementation reduces the perception of muscular fatigue and enhances overall muscular performance, which has led to its widespread use in sports medicine and elite athletic training
Supplementation with β-alanine has been shown to improve physical and cognitive performance during certain types of high-intensity physical activity, particularly exercises lasting from 1 to 10 minutes. Following ingestion, β-alanine is converted within myocytes into carnosine, a dipeptide that plays a key role in intracellular buffering. Carnosine contributes to the neutralization of lactic acid produced during high-intensity exercise, thereby delaying the onset of neuromuscular fatigue and enhancing exercise capacity and athletic performance. Currently, there is no reliable evidence demonstrating a direct effect of β-alanine on lifespan extension. However, by improving exercise performance and supporting physical capacity, β-alanine contributes to the physical component of age-related resilience. For this reason, it may be classified as a proresilient substance rather than a cellular chronoblocker.
