Creatine plays an important role in the body’s production of cellular energy because it helps make ATP, a molecule needed by all cells. The physiological need for creatine increases in individuals who exercise regularly, to prevent muscle damage.
Creatine also helps maintain hydration within cells. When you start creatine supplementation, you may see an increase on the scale as the body is holding on to more water within muscles.
Createine is also known to lessen muscle breakdown and to support cognitive function in aging populations.
