Beta-alanine is an amino acid which is contained in the skeletal muscles. Beta-alanine does not participate in the muscle building process, but it helps in achieving bigger muscle power and endurance. During a workout, the reduction of pH in the muscle cell leads to tiredness and fatigue, as the functions of the enzymes, participating in the creation of energy, are hindered. Beta-Alanine has a buffer function, as it reduces accumulation of hydrogen cations, respectively the acidity in the muscle cell, which leads to increase of muscle power and endurance. It is contained in a small variety of foods (veal and fish) and the easiest way to supply with enough of it is through supplementation. It is recommended for high volume workouts where more endurance is needed.
