Creatine Supplementation and Intramuscular Phosphocreatine

Direct Answer

• Yes, creatine supplementation effectively increases intramuscular total creatine and phosphocreatine concentrations.

Mechanism and Effects

• Saturation of Stores: Typical supplementation protocols lead to a 20% to 40% increase in total skeletal muscle creatine stores, with a significant portion stored as phosphocreatine.
• Enhanced Energy Availability: Higher intramuscular phosphocreatine levels improve the regeneration of adenosine triphosphate (ATP) during short-duration, high-intensity exercise.
• Individual Variability: The magnitude of the increase depends heavily on baseline levels, with individuals who have lower initial stores (such as vegetarians) often experiencing the greatest relative uptake.
