Compositions and methods are provided for producing crystalline forms of organic acids or salts or lactones thereof from an aqueous solution. More specifically, methods are provided for producing a crystalline form of a salt of mevalonic acid (also referred to as X-MVA) from an aqueous solution, comprising subjecting the aqueous solution comprising said X-MVA to a purification step to produce a purified solution and crystallizing said X-MVA from said purified solution by water solvent crystallization. Methods are also provided for producing mevalonolactone from an aqueous solution comprising X-MVA, comprising subjecting the aqueous solution comprising said X-MVA to cation exchange thereby converting said aqueous solution comprising X-MVA to an aqueous solution comprising mevalonolactone (MVL). Methods are also provided for producing mevalonolactone monohydrate crystals.
