Now Foods Beta Alanine 750mg Dietary Supplement for Fatigue Reduction & Muscle Recovery 120 Vegcaps Muscle growth, repair - Neuromuscular diseases. Beta-alanine is an amino acid used by muscle cells to synthesize carnosine, a dipeptide consisting of B-alanine and L-histidine. B-alanine is the only beta amino acid found in nature today. It is synthesized exclusively by the liver in the human body and is not absorbed through protein consumption. Direct intake of carnosine does not bring any effect as its absorption from the gastrointestinal system is considered negligible. The increase in carnosine levels after administration of B-alanine (an increase of more than 80% after several weeks of administration) results in the physiological potential of the dipeptide (B-alanine & L-histidine) reaching its full potential. Studies have shown that carnosine is partially capable of limiting the effects of lactic acid on the muscles, which contributes to the improvement of athletic performance. Increasing carnosine levels in the muscles can therefore improve mixed aerobic and anaerobic exercises. Carnosine also helps to mobilize enzymes responsible for the activation of muscle contractions. Research studies indicate that supplemental B-alanine significantly delays muscle fatigue.
