1. A cocrystal of ubiquinol and a hydrogen bond donor coformer,
wherein the hydrogen bond donor coformer is selected from the group consisting of 3-hydroxybenzoic acid and 3,4-dihydroxybenzoic acid,
wherein in the cocrystal of ubiquinol and 3-hydroxybenzoic acid, the molar ratio of ubiquinol and 3-hydroxybenzoic acid is 1:1;
wherein the cocrystal of ubiquinol and 3,4-dihydroxybenzoic acid is a hydrate; and
wherein in the cocrystal of ubiquinol and 3,4-dihydroxybenzoic acid, the molar ratio of ubiquinol, 3,4-dihydroxybenzoic acid, and water is 1:1:1.
