Athletic Performance

By continuously increasing muscle carnosine through beta-alanine supplementation, CarnoSyn® supplementation led to an 80% muscle carnosine increase, after a 58.8% increase was observed at 4 weeks, exercise capacity is improved further in a consequence of muscle carnosine increase.
