Q10 contains ubiquinol, the reduced, active form of coenzyme Q10, in a stable form from the Japanese company Kaneka. Kaneka QH™ ubiquinol is derived from yeast fermentation and it is a natural product. Q10 has a unique softgel capsule made of fish gelatin, which is colored red using beta-carotene. This protects the active ingredient ubiquinol from the influence of light.
