Beta – Alanine is a non-essential amino acid. In a wide range of studies beta – alanine has been shown to have benefits to high intensity exercise (57). The reason behind this is that it has been found to increase muscle carnosine concentrations (58). Carnosine is key to the intracellular PH buffering of skeletal muscle (59). With an increase in clearance of H+ ions, it leads to high intensity exercise lasting for longer.
