Beta Alanine is a non essential amino acid. It is a break down product of the naturally occurring peptide Carnosine. What it does is to help concentrate high levels of carnosine in the muscles. In doing this Beta Alanine provides high levels of energy, helping to support maximum muscular endurance and hence improved perfomance. The interest in muscle carnosine levels arises from the fact that carnosine is known to be a powerful buffering agent. That is, it can neutralise acidity caused when lactic acid concentrations rise during intense exercise, which is a contributing factor in muscular fatigue. Muscle carnosine levels are limited by the amount of beta alanine available, thus supplementing with beta alanine has been shown to decrease athletic fatigue and increase the amount of work that can be done by the muscles. Our Pro Beta Alanine Supplement is 100% pure with no other additives or carriers.
