Alternative forms of creatine (e.g., creatine HCl, creatine ethyl ester, creatine malate) are not superior to creatine monohydrate (CM) in increasing muscle creatine content or improving exercise performance, despite marketing claims suggesting otherwise.

If you are buying creatine, stick to creatine monohydrate (CM). Alternative forms like creatine HCl, ethyl ester, or malate are marketed as superior, but scientific evidence shows they are not better at increasing muscle creatine or improving performance than standard CM. You are likely paying significantly more (up to 116% higher per gram) for no additional benefit.

GoodRefutesHIGH confidence
none have been to be superior to CM in terms of increasing muscle creatine content [35] despite the commonly used marketing claims/marketing hyperbole shown in Figure 1.
