Creatine is a natural substance that turns into creatine phosphate in the body. Creatine phosphate helps make a substance called adenosine triphosphate (ATP). ATP provides the energy for muscle contractions.
Given that ATP is the cell’s energy currency, instantaneous power is determined by the size of your muscular bank account. Your muscles only save enough ATP to pay for brief bouts of strenuous activity. Since most of us can sustain maximal power for more than just a few seconds, there has to something more and, in fact, there – creatine.
Performance Enhancement
The basic idea behind creatine supplementation is simple: to provide your muscles with more creatine than they can degrade. Your muscles should then respond to surplus by stockpiling creatine reserves.
Creatine’s principle duty is to increase the availability of ATP, the cell’s energy currency.
