Creatine, as well as a creatine analogue called cyclocreatine, inhibit growth of a broad range of solid tumors in rat models of cancer; these tumors express high levels of CK. Although the mechanism for tumor inhibition is unknown...

Phosphocreatine inhibits enzymes in the glycolitic pathway, including glyceraldehydes-3-phosphate dehydrogenase, phosphofructokinase and pyruvate kinase.

Safety data are lacking and are urgently needed, especially for long-term use of creatine and for use among the pediatric population (including adolescence) and among those in poor health. There are some reports that long-term use of creatine may be nephrotoxic. This needs further investigation before long-term creatine supplementation can be recommended under any circumstance.

Creatine is contraindicated in those with renal failure and renal disorders such as nephritic syndrome.

There are reports of elevated serum creatinine, a metabolite of creatine and a marker of kidney function, in some who take creatine and have normal renal function. This /effect on renal function tests/ is reversible upon discontinuation of creatine.

For nutritional supplementation, also for treating dietary shortage or imbalance.
Creatine is a essential, non-proteinaceous amino acid derivative found in all animals. It is synthesized in the kidney, liver, and pancreas from L-arginine, glycine and L-methionine. Following its biosynthesis, creatine is transported to the skeletal muscle, heart, brain and other tissues. Most of the creatine is metabolized in these tissues to phosphocreatine (creatine phosphate). Phosphocreatine is a major energy storage form in the body. Supplemental creatine may have an energy-generating action during anaerobic exercise and may also have neuroprotective and cardioprotective actions.
In muscle and nerve, most of the creatine is phosphorylated to phosphocreatine (pCr) in a reaction that is catalyzed by the enezyme creatine kinase (CK), there are three isoforms of (isoenzymes) of CK. CK-MM is the skeletal muscle isoform; CK-BB, the brain isoform, and CK-MB, the isoform found in cardiac muscle. Most of the PCr in the body is in skeletal muscle.

Creatine is absorbed from the small intestines and enters the portal circulation and is transported to the liver. The ingested creatine, and the creatine made in the liver, is then transported into the systemic circulation and distributed into various tissues of the body, including muscle and nerves, by crossing the cell membrane via a specific creatine-transported system against a 200:1 gradient.

Within muscle and nerve cells, about 60 to 67% of the creatine entering the cells gets converted to phosphocreatine via the enzyme creatine kinase. About 2% of creatine is converted to creatinine, and both creatine and creatinine are excreted by the kidneys.

In the muscles, a fraction of the total creatine binds to phosphate - forming creatine phosphate. The reaction is catalysed by creatine kinase, and the result is phosphocreatine (PCr). Phosphocreatine binds with adenosine diphosphate to convert it back to ATP (adenosine triphosphate), an important cellular energy source for short term ATP needs prior to oxidative phosphorylation.
Supplemental creatine may have an energy-generating action during anaerobic exercise and may also have neuroprotective and cardioprotective actions.

Creatine, creatine kinase and phosphocreatine make up an intricate cellular enegy buffering and transport system connecting sites of energy production in the mitochondria with sites of energy consumption. CK is a key enzyme in involved in cellular energy homeostasis. It reversibly catalyzes the transfer of the high-energy phosphate bond in PCr to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP), and it catalyzes the transfer of the high-energy phosphate bond in ATP to creatine to form PCr. During periods of intense exercise and skeletal muscle contraction, bioenergetic metabolism switches from one in which oxidative phosphorylation is the major pathway of ATP production to one in which so-called anaerobic glycolysis becomes dominant.
