What is co-enzyme Q10?

Co-enzyme Q10, commonly known as CoQ10, is a vitamin-like compound found in virtually every cell of your body. Levels are particularly high in energy-demanding tissues such as your heart, liver and kidneys.

CoQ10 exists mainly as ubiquinone and ubiquinol, which your body can convert between as needed. Your body produces CoQ10 naturally, but production can decline with age.

This has made CoQ10 a popular nutrient for supporting cellular energy and healthy ageing.

The engine room of the cell

CoQ10 plays a vital role in your mitochondria, the structures within your cells that produce energy in the form of ATP. It helps transfer electrons through the electron transport chain, supporting efficient cellular energy production.

Your heart has particularly high energy demands because it works continuously throughout your life. This is one reason CoQ10 has attracted considerable research interest in relation to normal heart function and cardiovascular health.

Antioxidant protection and healthy ageing

CoQ10 also acts as a fat soluble antioxidant, helping protect your cells from oxidative stress. It is particularly important within cell membranes and mitochondria.

CoQ10 can also help regenerate vitamin E after it has neutralised free radicals. These antioxidant roles have made CoQ10 a subject of interest in healthy ageing research.

Choosing between ubiquinone and ubiquinol

CoQ10 supplements are available as ubiquinone and ubiquinol. Your body can convert ubiquinone into ubiquinol as needed.

Ubiquinone is the traditional and widely available form. Ubiquinol is the reduced form, which some products use for potentially improved absorption.

CoQ10 is fat soluble, so taking it with a meal containing dietary fat can support its absorption.

Statin medicines can reduce the body’s natural CoQ10 production. If you take statins, speak with your healthcare professional before using CoQ10 supplements.
