The present invention relates to a co-crystal of coenzyme QH and nicotinamide, a preparation method therefor and the use thereof. Compared with the existing coenzyme QH, the co-crystal has a higher melting point and superior stability. The preparation method for the co-crystal of coenzyme QH is simple, easy to control and good in terms of reproducibility. The present invention greatly improves the use convenience of coenzyme QH, saves costs during storage, transportation and use, and broadens the application range of coenzyme QH.

It is an object of the present disclosure to provide a method for producing a reduced coenzyme Q10 Form II crystal or a crystalline solid thereof, which is excellent in the filterability of a slurry containing a reduced coenzyme Q10 Form II crystal.

The present embodiment is a method for producing a reduced coenzyme Q10 Form II crystal or a crystalline solid thereof, including: adding a reduced coenzyme Q10 Form II crystal as a seed crystal to a mixed solution containing an alcohol and a reduced coenzyme Q10; and precipitating a reduced coenzyme Q10 Form II crystal in the mixed solution after adding the seed crystal, wherein a change rate of formazin turbidity (FTU) is maintained at 15 FTU/min or more for 80% or more of a period during which the formazin turbidity (FTU) shifts from 1,000 to 10,000 in the precipitation.
