There appears to be a balance between intracellular creatine and creatine circulating in blood. This balance can be altered slightly by creatine ingestion. Within a few days, intracellular Cr levels reach a new equilibrium level. A much smaller fraction of this additional creatine appears to be stored in the high-energy phosphocreatine form, however. Supplementation Creatine can be found in many forms.
Commercial supplements are also available.
Energy Effect A number of studies have examined the effect of creatine supplementation on performance. The mechanism of this enhancement is not yet clearly documented, but is most likely by increasing the available PCr pool. References Greenhaff, P.L. Creatine and its application as an ergogenic aid.
