Abstract

See full text

Provided is a production method capable of efficiently producing a reduced coenzyme Q10 Form II crystal. A method for producing reduced coenzyme Q10 crystals comprises warming a mixture of a reduced coenzyme Q10 Form I crystal and a reduced coenzyme Q10 Form II crystal to 32° C. or higher, in the presence of 0.001 to 50 parts by weight of a solvent with respect to 100 parts by total weight of the crystals, so as to increase the content of the reduced coenzyme Q10 Form II crystal. The warming time may be 1 hour or more and less than 14 hours, and after the warming of the mixture in the presence of the solvent, drying may be performed at 45° C. or higher to remove the solvent.
