Graef et al [ 35 ] examined the effects of four weeks of creatine citrate supplementation and high-intensity interval training on cardio respiratory fitness.
A number of potential therapeutic benefits have also been suggested in various clinical populations. For technical and performance comparisons, literature searches were performed by searching the Medline database of the US National Library of Medicine of the National Institutes of Health.
Samples of each product passed all six heavy metals assays, indicating that samples contained under 1 PPM part per million each of arsenic, lead, cadmium, bismuth, antimony, and silver compounds. Product Purity All 25 creatine supplements tested in this batch passed heavy metal screens for arsenic, lead, and cadmium below 1 PPM.
Articles were reviewed, analyzed, and interpreted, with results of the relevant studies presented below. Several studies have compared monohydrate and other forms for their effects on exercise performance. This result pointed to the ability of the body to store creatine, which in turn suggested its use as a dietary supplement.
Similar findings have also been reported for creatine monohydrate supplementation alone when combined with resistance training [ 71 ]. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only 3 times a week.
Creatine supplementation and exercise performance: Articles were reviewed, analyzed, and interpreted, with results of the relevant studies presented below. Creatine can be cleared from the blood by saturation into various organs and cells or by renal filtration [ 1 ].

Creatine supplementation protocols have been shown to increase brain creatine and phosphocreatine contents. It has been advised that further research be carried out into the effects of creatine supplementation and health in the elderly and adolescent [ 7375 ].Creatine is the reference compound for power improvement, with numbers from one meta-analysis to assess potency being "Able to increase a 12% improvement in strength to 20% and able to increase a 12% increase in power to 26% following a training regiment using creatine monohydrate".
Creatine supplements are marketed in ethyl ester, gluconate, monohydrate, and nitrate forms.
 A survey of 33 supplements commercially available in Italy found that over 50% of them exceeded the European Food Safety Authority recommendations in at least one contaminant.
