Coenzyme Q10 is synthesised naturally in humans and is also found in foods, such as vegetables and fish. It acts as a cofactor in the electron transfer pathway which produces energy (in the form of adenosine triphosphate - ATP) within the mitochondria of human cells. The energy is used for muscle contraction and other vital functions. It is also an antioxidant which may have a sparing effect on vitamins C and E in situations of oxidative stress. Diminished concentrations of coenzyme Q10 have been reported with increasing age, on statin medication and in various disorders including cardiovascular disease and cancers.
No coenzyme Q10 containing supplements for 24 hours prior to testing
