β-Alanine is rapidly developing as one of the most popular sport supplements used by strength/power athletes worldwide. The popularity of β-alanine stems from its unique ability to enhance intramuscular buffering capacity and thereby attenuating fatigue. This review will provide an overview of the physiology that underlies the mechanisms of action behind β-alanine, examine dosing schemes, and examine the studies that have been conducted on the efficacy of this supplement. In addition, the effect that β-alanine has on body mass changes or whether it can stimulate changes in aerobic capacity also will be discussed. The review also will begin to explore the potential health benefits that β-alanine may have on older adult populations. Discussion will examine the potential adverse effects associated with this supplement as well as the added benefits of combining β-alanine with creatine.
