The present invention relates to a method of conveniently and efficiently producing high-quality reduced coenzyme Q<SUB>10 </SUB>which is useful as an ingredient in foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, animal drugs, drinks, feeds, cosmetics, medicines, remedies, preventive drugs, etc. This method is suitable for industrial production thereof. A method of producing a reduced coenzyme Q<SUB>10 </SUB> which comprises reducing an oxidized coenzyme Q<SUB>10 </SUB>in an aqueous medium with the use of dithionous acid or a salt thereof, said reduction being carried out in the coexistence of a salt and/or under deoxygenated atmosphere, and at pH of 7 or below. Thus, the formation of the oxidized coenzyme Q<SUB>10 </SUB>as a by-product due to oxidation can be minimized, thereby giving reduced coenzyme Q 10 having excellent qualities in a high yield. |
