Coenzyme Q10

Coenzyme Q10 (CoQ10) is a naturally occurring compound found in nearly every cell of the body. It plays a central role in mitochondrial energy production and also acts as an antioxidant, helping protect cell membranes and other structures from oxidative stress.

CoQ10 is especially concentrated in tissues with high energy demands, including the heart, muscles, liver and kidneys.

Cellular Energy and Mitochondria

Inside the mitochondria, CoQ10 helps transfer electrons through the processes used to produce ATP, the immediate energy source used by cells.

This makes CoQ10 particularly relevant to organs and tissues that require a constant supply of energy. Natural production can decline with age, while certain medications and health conditions may also influence CoQ10 levels.

Heart and Circulation

The heart is one of the most metabolically active muscles in the body and contains relatively high concentrations of CoQ10.

Its combination of energy support and antioxidant activity has made CoQ10 a common ingredient in formulas for cardiovascular health, circulation and healthy ageing.

CoQ10 also helps protect lipids and cell membranes from oxidation, supporting normal cellular function throughout the cardiovascular system.

Exercise and Physical Recovery

Muscle contraction places considerable demand on cellular energy production.

By supporting mitochondrial ATP production, CoQ10 can contribute to normal muscle function, physical energy and recovery. Its antioxidant activity also helps cells manage some of the oxidative stress generated during exercise and everyday metabolism.

This makes it a useful ingredient in formulas for active people, healthy ageing and general vitality.

Ubiquinone and Ubiquinol

CoQ10 occurs mainly in two forms: ubiquinone and ubiquinol.

Ubiquinone is the oxidised form traditionally used in many supplements, while ubiquinol is its reduced form and plays an important role in antioxidant protection. The body naturally converts between the two as part of normal cellular metabolism.

Because CoQ10 is fat-soluble, it is generally best absorbed when taken with food containing some dietary fat.

CoQ10 for Pets

CoQ10 also supports mitochondrial energy production and antioxidant defence in dogs and cats.

It is particularly relevant in pet formulas aimed at heart health, cellular energy, physical performance and healthy ageing, and may be paired with nutrients such as L-carnitine, taurine and omega-3 fatty acids for broader cardiovascular and metabolic support.

CoQ10 in O2B Products

At O2B Healthy, CoQ10 is available in O2B Co-Q10 150mg and is also included in O2B Collagen+ and O2B Red Yeast Rice+Co-Q10. For active dogs, it is used in O2B K9+ Octane alongside D-ribose, creatine, L-carnitine and other performance nutrients. Across these formulas, CoQ10 supports mitochondrial energy production, antioxidant defence, cardiovascular function, circulation, stamina and healthy ageing.
