The present invention provides a crystal of a monovalent cation salt of 3-hydroxyisovaleric acid (hereinafter, referred to as HMB), which is excellent in solubility and easy to handle, and a process for producing the crystal. A crystal of a monovalent cation salt of HMB is precipitated in an aqueous HMB solution containing a monovalent cation-containing compound and having a pH of 4.0 to 9.0, and the crystal of a monovalent cation salt of HMB is thereafter collected from the aqueous solution.

Solid formulations of sodium 3-hydroxy-3-methylbutyrate are produced by the hydrolysis of 4,4-dimethyl-2-oxetanone with aqueous sodium hydroxide to give a solution of sodium 3-hydroxy-3-methylbutyrate and the solution obtained thus is absorbed onto synthetic silicic acid. Said formulations are lightly hygroscopic and easily handled.
