What is Ubiquinol?

Ubiquinol is a form of CoQ10 (Coenzyme Q10) that is the active and readily bioavailable form and supports cellular energy throughout our body.

This potent antioxidant is a nutrient found naturally in every cell of our bodies, helping our organs perform their functions. As we age and are exposed to lifestyle stresses, our bodies’ natural levels of Ubiquinol decline as does our ability to convert CoQ10 to Ubiquinol.5 This may affect our energy levels, our cardiovascular health, and our fertility.

Speak to your healthcare practitioner before taking Ubiquinol to determine if it is suitable for you.

Always read the label. Use only as directed. If symptoms persist, consult your healthcare practitioner.

Ubiquinol vs Coenzyme Q10

Better absorption

Ubiquinol is the active form of CoQ10 and is easily absorbed by the body.9

Antioxidant protection

CoQ10 must be converted to Ubiquinol in the body to exert its antioxidant effects.7

Easier for the body

to use as we age

As we age our body finds it harder to convert CoQ10 to Ubiquinol10 which may reduce essential antioxidant protection.

More direct benefits

Ubiquinol, the reduced form of CoQ10, provides virtually all of the health benefits associated with CoQ10.6

Improved heart health

Poor heart health makes it harder for the heart to convert CoQ10 to Ubiquinol. Taking readily usable Ubiquinol supports normal, healthy cardiovascular health.

Anti-aging benefits

After the age of 30 our body finds it harder to convert CoQ10 to Ubiquinol,7 which is the form that provides antioxidant protection against ageing.8

Scientific Research

CoQ10 has been the subject of more than 50 years of clinical research from acclaimed institutions worldwide.

In the last decade, Medicine has shone the spotlight on Ubiquinol, the active form of CoQ10, with more than 60 studies to demonstrate its efficacy in supporting mitochondrial energy.

Clinical studies show that Ubiquinol supports energy production and provides antioxidant benefits for cardiovascular health and healthy fertility.
