Beta-alanine plays a crucial role in enhancing exercise performance, particularly in high-intensity activities. This amino acid helps increase the production of carnosine in muscles, which buffers acid buildup during intense exercise. As a result, it improves endurance and reduces fatigue, allowing athletes to train harder and longer. Supplementing with beta-alanine has been shown to enhance performance in tasks lasting 1-4 minutes, making it a popular choice among athletes seeking to improve their training results.
