The function of beta-alanine in performance enhancement is primarily related to its role in increasing muscle carnosine levels, which helps buffer acid in muscles during high-intensity exercise. By reducing acidity, beta-alanine can enhance performance, particularly in activities lasting more than a minute, such as sprinting or weightlifting. This effect may lead to improved endurance and reduced fatigue during intense workouts. Supplementing with beta-alanine allows athletes to train harder and longer, ultimately supporting greater muscle growth and overall fitness improvements.
