About Ubiquinol

Get to Know the Ubiquitous Coenzyme

Coenzyme Q10 (CoQ10) is a fat-soluble molecule naturally present in every cell of the body. It is an essential part of the mitochondrial respiratory chain.

CoQ10 is naturally synthesized by the body and consumed as part of a regular diet. Dietary sources, however, generally provide less than 3 mg/serving, which is insufficient to effectively replenish depleted CoQ10 levels.1,2

Overall CoQ10 levels in the body may be reduced by a number of causes, including aging,3 certain health conditions,4 and use of statin medications.5

CoQ10 Has 2 Forms: Ubiquinone and Ubiquinol

  • Ubiquinone is the oxidized form of CoQ10
  • Ubiquinol is the reduced form of CoQ10
    • Has 2 additional electrons
    • Active antioxidant form6,7

CoQ10 cycles between its oxidized state, ubiquinone, and its reduced form, ubiquinol, as it performs its role in energy generation and, as ubiquinol, supplying antioxidant activity.8

Whether synthesized naturally or taken as a CoQ10 supplement, ubiquinone must be converted by the body into ubiquinol for it to be transported in the blood and act as an antioxidant.9,10

Ubiquinol Plays a Crucial Role in Cellular Health

Ubiquinol is the active antioxidant form of CoQ10.6,7 It shields cells against oxidative stress, which may affect lipids, proteins, and DNA.11,12

In healthy adults, approximately 95% of CoQ10 circulating in the blood is in the form of ubiquinol.13,14

Ubiquinol drives production of adenosine triphosphate (ATP), the energy currency of the cell.15

Vitamin E, another essential lipid-soluble antioxidant, is only obtainable from dietary sources. Ubiquinol is unique in that it is the only lipid-soluble antioxidant synthesized by the body and is capable of regenerating vitamin E.7

Ubiquinol, a lipid-soluble antioxidant, is concentrated where reactive oxygen species are formed1-5

Developed for enhanced absorption, Kaneka Ubiquinol® is the active antioxidant form of CoQ10.1,2 In the body, ubiquinol is concentrated in the mitochondrial lipid membrane, where reactive oxygen species (ROS) are formed. This makes it an ideal antioxidant to neutralize potentially harmful ROS.2-5

Unlike a conventional CoQ10 (ubiquinone) supplement, which must be converted in the body before it can function as an antioxidant, Kaneka Ubiquinol® performs its antioxidant functions without requiring conversion.6,7
