Product overview

Mode of action

Co-enzyme Q10 (also known as ubiquinone or ubidecarenone) is a fat-soluble compound primarily synthesised by the body and also consumed in the diet. It is involved in the process of energy production by mitochondria and functions as an antioxidant in cell membranes and lipoproteins.

Regulatory status

Co-enzyme Q10 has no licensed indications as a medicine in the UK.

In line with the guidance from the General Medical Council (GMC) on prescribing unlicensed medicines, the prescriber should take full responsibility for determining the needs of the patient and whether using co-enzyme Q10 is suitable. Supporting information and advice is also available from the GMC.
