Tell Your Patients to Look for the Kaneka Quality Seal

Find Supplements Containing Authentic Kaneka Ubiquinol®

Help patients identify Kaneka Ubiquinol® by looking for the Kaneka Quality Seal, featured on more than 200 trusted supplement brands. This mark ensures your patients are getting the most studied and trusted form of ubiquinol available.

What Is the Kaneka Quality Seal?

The Kaneka Quality Seal is a mark of authenticity. It appears only on products made with genuine Kaneka Ubiquinol®, the active antioxidant form of coenzyme Q10 (CoQ10).

Kaneka Ubiquinol® is made in the USA at our state-of-the-art manufacturing facility in Pasadena, Texas, where we employ stringent quality controls to ensure potency, purity, and absorption.
