There have been no studies to prove the benefits of creatine phosphate over creatine monohydrate. Creatine phosphate is a type of creatine that includes a phosphate molecule to speed up the conversion to phosphocreatine in the body. However, it delivers a smaller amount of dietary creatine per gram and is more expensive. In the absence of research confirming its benefits, we recommend sticking with 5 grams per day of creatine monohydrate.
