Creatine’s primary mechanism of action revolves around its involvement in the phosphocreatine (PCr) system, a rapid energy buffer within cells. When adenosine triphosphate (ATP), the body’s primary energy currency, is hydrolyzed to adenosine diphosphate (ADP) during muscle contraction, energy is released. The PCr system rapidly rephosphorylates ADP back to ATP, allowing for sustained high-intensity efforts. Creatine supplementation increases intracellular creatine and PCr stores, thereby enhancing the capacity for ATP regeneration and delaying the onset of fatigue.
Furthermore, creatine may exert its effects through other pathways, including modulating gene expression, enhancing satellite cell proliferation (important for muscle repair and growth), buffering acidosis, and acting as an antioxidant. These diverse mechanisms contribute to its wide array of observed benefits.
