CoQ10, also known as coenzyme Q10, is commonly used to support cellular energy production, mitochondrial function, antioxidant protection and cardiovascular health. It is especially relevant for cells and organs with high energy demands, such as the heart, muscles and brain.

CoQ10 helps support mitochondrial energy production by assisting the process that converts nutrients into ATP, the body’s main cellular energy currency. It also acts as an antioxidant, helping protect cells from oxidative stress.

CoQ10 is commonly used to support cardiovascular function because the heart requires a high amount of cellular energy. It may support healthy heart muscle function, antioxidant balance and overall cardiovascular wellbeing.

CoQ10 may support energy by helping mitochondria produce ATP more efficiently. It is not a stimulant and does not contain caffeine, so it supports cellular energy pathways rather than giving a quick energy spike.

Ubiquinone and ubiquinol are two forms of CoQ10. Ubiquinone is the oxidised form, while ubiquinol is the reduced form. The body can convert between the two forms, and suitability may depend on individual needs, age, absorption and practitioner guidance.

CoQ10 is best taken with food, especially a meal that contains some fat, because it is fat-soluble. Taking it with food may support absorption and digestive comfort.

People taking statin medication often ask about CoQ10 because statins may affect CoQ10 levels. Speak with a healthcare professional before combining CoQ10 with any cholesterol-lowering medication or cardiovascular treatment.

Use caution when combining CoQ10 with other mitochondrial, antioxidant or energy-support supplements such as PQQ, NADH, carnitine, alpha-lipoic acid, B vitamins or high-strength multivitamins. Overlapping formulas may not be necessary unless professionally advised.

Speak with a healthcare professional before using CoQ10 if you are pregnant, breastfeeding, planning pregnancy, taking medication, using blood pressure, cholesterol, diabetes or blood-thinning medication, managing a heart condition, shopping for a child, or unsure whether CoQ10 is suitable for you.

No. CoQ10 is a nutritional supplement and is not intended to diagnose, treat, cure or prevent disease. Persistent fatigue, chest pain, shortness of breath, dizziness, weakness or cardiovascular symptoms should be assessed by a qualified healthcare professional.
