NCIt definition : The monohydrate form of creatine similar or identical to endogenous creatine produced
in the liver, kidneys, and pancreas. Creatine, in phosphate form, helps supply energy
to muscle cells for contraction. After intense effort, when ATP deposits are depleted,
creatine phosphate donates phosphate groups toward the fast synthesis of ATP. Dietary
supplementation with creatine may improve muscle wasting associated with cancer and
other chronic diseases.;
