The benefits of creatine are well-documented. It increases lean body mass, strength, performance, and phosphocreatine–an energy source–stores in muscle. The debate is what form of creatine is best. While many companies attempt to reinvent the wheel with new forms of creatine so they can charge you a premium, the overwhelming majority of research showing the benefits of creatine supplementation has been performed with creatine monohydrate. While some other forms may be as effective as creatine monohydrate, no other form has been demonstrated to be more effective than creatine monohydrate.
