Abstract

A process for purifying creatine is described in which the creatine to be purified in the form free of water of crystallization is introduced into a saturated aqueous solution of creatine monohydrate, in which the creatine free of water of crystallization is dissolved with hydration, crystals of creatine monohydrate precipitate from the aqueous solution and these are separated off from the aqueous solution.
