Naturally-Occurring Amino Acid for Promoting Reduction in Muscle Fatigue. Perform. Recover. Recharge. Improves muscular endurance by increasing your muscles' ability to buffer lactic acid. Supported by research to delay muscle fatigue and improve performance during high-intensity exercise. Beta-Alanine is considered to be the "new creatine" in sports performance; not because it can replace the proven strength/muscle builder, but because it is proven to boost performance and muscular endurance for high-intensity exercise. Whereas creatine is considered ideal for boosting absolute strength, Beta-Alanine is considered ideal for the higher intensity rep ranges because of its ability to promote the buffering of lactic acid. Beta-Alanine is a non-essential amino acid that is used by muscle cells to synthesize carnosine, which functions as a bugger to the hydrogen ions (acid) produced during strenuous exercise, thus helping to maintain optimum muscle pH. Clinical studies suggest that Beta-Alanine supplementation can delay muscle fatigue.
