Abstract:
The present invention provides a crystal of reduced glutathione that is stable, and is easy to process, and a method for producing the crystal. According to the present invention, a crystal of a metal salt of reduced glutathione is produced by suspending an amorphous solid of a metal salt of reduced glutathione in a hydrophobic organic solvent, and adding water to the resulting suspension to precipitate a crystal of a metal salt of reduced glutathione.
