The recommended dose of Kaneka Ubiquinol varies based on each individual’s needs. However, those who are older or suspect they have decreased CoQ10 due to disease or prescription medications may want to start supplementing with 200 mg of Kaneka Ubiquinol per day. Studies show that the CoQ10 plasma levels plateau at about two weeks at this dose. After that, 100 mg per day is a good daily maintenance dose.
