Ingredients

Creatine monohydrate (CM) is defined as a nitrogenous organic acid that occurs naturally in humans and aids in the supply of energy to cells in the body, (1). The majority of CM, 95%, can be located in the skeletal muscle with the rest distributed to the brain, heart and smooth muscles.

Creatine has been found to increase the replenishment of ATP stores in the skeletal muscles (2). It is attributed to a greater rate of phosphocreatine resynthesis during rest periods. Higher sprint speeds are reported (3). There have been numerous theories proposed as to why creatine provides a benefit to short term high intensity exercise (4). One theory is that the increased amount of phosphocreatine (PCr), can be used as an immediate buffer to ATP which reduces the dependence of glycolysis which delays the production of lactate and hydrogen ions during exercise thus prolonging the activity by delaying the onset of fatigue, (5).
