Although creatine is one of the most widely used nutritional supplements for athletes as well as for patients with neuromuscular disorders, the effects of oral creatine supplementation on endogenous creatine synthesis in humans remains largely unexplored. The aim of the present study was to investigate the metabolic consequences of a frequently used, long-term creatine ingestion protocol on the...

This study investigated the effect of creatine supplementation in conjunction with protein and/or carbohydrate (CHO) ingestion on plasma creatine and serum insulin concentrations and whole body creatine retention. Twelve men consumed 4 x 5 g of creatine on four occasions in combination with 1) 5 g of CHO, 2) 50 g of protein and 47 g of CHO, 3) 96 g of CHO, or 4) 50 g of CHO. The increase in ser...

Background It has been well-established that creatine monohydrate (CrM) increases whole body creatine retention and muscle creatine content. Extracts of Russian Tarragon (RT) have been reported to produce anti-hyperglycemic effects [1] and influence plasma creatine levels during the ingestion of CrM [2]. Theoretically, RT ingestion with CrM may promote greater creatine retention than ingesting ...

Creatine is an amino acid derivate commonly found in vertebrate muscle tissue. facilitates the recycling of adenosine triphosphate and thus contributes to energy supply muscles as well brain. used a supplement for several reasons its effects humans, particularly sports medicine, have been studied excessively. Also, creatine supplementation has functions benefits terrestrial farm animals. Up dat...

Creatine is a nutritional compound that potentially influences cognitive processing and neuroprotection. Recent evidence has demonstrated similar to neurotransmitters, creatine released in an excitotoxic action potential-dependent manner acts as neuromodulator. deficiency syndromes are characterized by severe mental developmental disorders. Studies have reported brain content could be enhanced ...

We report a case of a heretofore healthy 18-year-old man who presented with a 2-day history of nausea, vomiting and stomach ache while taking creatine monohydrate for bodybuilding purposes. The patient had acute renal failure, and a renal biopsy was performed to determine the cause of increased creatinine and proteinuria. The biopsy showed acute tubular necrosis. In the literature, creatine mon...

social and financial ties. This does not release us from normal professional responsibility. Child abuse is addressed in a recent leaflet entitled "Protecting children from abuse",' the result of a project that was initiated by Amateur Swimming Federation, developed by the National Society for the Protection (NSPCC) and National Coaching Foundation, and supported by the Sports Council and Child...

The effect of creatine and caffeine supplementation on muscle torque generation and relaxation was investigated in healthy male volunteers. Maximal torque (T(max)), contraction time (CT) from 0.25 to 0.75 of T(max), and relaxation time (RT) from 0.75 to 0.25 of T(max) were measured during an exercise test consisting of 30 intermittent contractions of musculus quadriceps (2 s stimulation, 2 s re...

BACKGROUND Creatine monohydrate has become a very popular nutritional supplement for its ergogenic effects. The safety of creatine monohydrate has previously been confirmed. However with each novel form of creatine that emerges, its safety must be verified. Therefore, the purpose of this study was to examine the safety of a novel form of creatine, creatine nitrate (CN), over a 28 day period. ...
