Abstract: Purification of creatine (I) involves adding the (I) to be purified, in anhydrous form, to a saturated aqueous solution of (I) monohydrate, so that the anhydrous (I) is dissolved with hydration, then separating the crystals of (I) monohydrate which precipitate from the solution. An Independent claim is also included for the preparation of (I) monohydrate, by: (a) reacting sarcosine with an guanylating agent in an aqueous medium, so that crude (I) monohydrate is precipitated; (b) separating the crude product form the medium; (c) optionally washing; (d) converting the product into anhydrous (I); (e) adding the anhydrous (I) to a saturated aqueous solution of (I) monohydrate, so that the anhydrous (I) is dissolved with hydration; (f) separating the crystals of (I) monohydrate which precipitate from the solution; and (g) utilizing the aqueous solution at least partially as aqueous medium in step (a) and/or washing liquid in step (c).
