Creatine monohydrate is a specific form of creatine that is excellently suited for use as a dietary supplement. It is stable, effective, safe and easily absorbed by the body. The regular intake of creatine monohydrate can help to replenish the body's creatine memory. To date, no form of creatine has been found to be more effective in recognized research compared to creatine monohydrate.
Creatine monohydrate is by far the best-studied form of creatine. It is also the form of creatine, which is most commonly recognized by food authorities worldwide. The European Food Safety Authority, in its safety assessment of creatine, also makes explicit reference to creatine monohydrate.
Other creatine forms
Apart from creatine monohydrate and related salts, such as creatine citrate or creatine pyruvate with improved solubility, there are other forms of creatine. However, these are much less researched in general, and not permitted in many countries. In addition, they are usually more expensive than the monohydrate form.
There is no scientific evidence that new creatine compounds are any more effective than creatine monohydrate. In some cases the effect also deteriorates over time because the core skeleton of the creatine molecule has been altered in such a way that the newly-formed compound behaves differently and sometimes unexplainedly in the body. An example of this is creatine ethyl ester (CEE). While creatine monohydrate is almost completely absorbed into the body, there are scientific studies that show that CEE is rapidly decomposed in the gastrointestinal tract into an ineffective form of creatinine.
