The present invention relates to the supply of coenzyme Q which is highly useful in maintaining human health, and provides a method and preparations whereby coenzyme Q can be efficiently supplied to patients having difficulties in oral administration, aged having swallowing difficulties and patients with diseases caused by topical disorders. It is found that the coenzyme Q concentration in the blood or topical mucosae can be elevated by using a composition for transmucosal administration containing oxidized coenzyme Q and/or reduced coenzyme Q as the active ingredient, wherein the total content of the oxidized coenzyme Q and the reduced coenzyme Q amounts to 0.0001 to 99% by weight of the whole composition. |
