Results have been mixed, with some studies showing a significant reduction in sprint times, whereas others have found the opposite and concluded that creatine supplementation is not effective in swimmers Fig.

These available methyl groups can then be used to activate key anabolic pathways. The results of this study [ 65 ] showed that ethyl ester was not as effective as CM to enhance serum and muscle creatine stores.

As for the anabolic role of various Cr regimens, an increase in body mass 1. Muscle Nerve ;27 5: This perception of safety cannot be guaranteed especially that of the long term safety of creatine supplementation and the various forms of creatine which are administered to different populations athletes, sedentary, patient, active, young or elderly throughout the globe.

Furthermore, creatine supplementation does not increase symptoms nor negatively affect hydration or thermoregulation status of athletes exercising in the heat [ 8384 ].

Creatine can provide other neuroprotective benefits through stabilisation of mitochondrial membranes, stimulation of glutamate uptake into synaptic vesicles and balance of intracellular calcium homeostasis [ 72 ].

In addition, several authors caution that long-term administration of creatine will likely lead to the downregulation of the creatine carrier protein and, thus, an increased resistance to the compound. Creatine is thought to improve strength, increase lean muscle mass, and help the muscles recover more quickly during exercise.

J Appl Physiol ; If your urine resembles apple juice, then chances are you are not hydrated. Inhibition of rate of tumor growth by creatine and cyclocreatine. Patients have been supplemented with 40 g while in healthy adults positive results have been reported with around 20 g per day [ 49 ].Creatine: A Complete Overview – By Wayne Mutata October 27, Wayne Mutata Creatine, Supplements 0 Regardless of the level of athlete I am putting a supplement stack together for, be it a professional athlete or recreational lifter, creatine is one of the most important supplements I have on my check list.
