Supplementation with Beta-alanine has been shown to increase the concentration of carnosine in muscles, decrease fatigue in athletes and increase total muscular work done. Beta-alanine is the rate-limiting precursor of carnosine, meaning carnosine levels are limited by the amount of available Beta-alanine. In scientific studies, beta Alanine has been shown to increase strength, power output, endurance, exercise capacity, muscle mass, and delay the onset of neuromuscular fatigue. Beta Alanine is perfect for anyone who practices a sport where strength, power and endurance are needed. Increase Muscular Strength & Power Output. Increase Energy, Endurance, & Stamina. Support Lean Muscle Mass. Delay Muscular Fatigue. Beta-Alanine is a lactic acid buffer that increases training capacity giving you the ability to train harder and longer. Weight training and athletic activities cause your body to produce lactic acid. This causes muscle pH to drop and become more acidic due to the large amount of hydrogen ions produced. As muscle pH drops, your muscle's ability to perform at its peak level decreases, Beta-Alanine works by increasing muscle carnosine levels, which in turn, works as a muscle buffer by soaking up these extra hydrogen ions.
