CoQ10 is also known as ubiquinone, and is a vitamin-like substance found within every cell in the human body where it plays an important role in the release of energy from the food we eat. It is therefore not surprising to find the highest concentrations of CoQ10 in those organs which have the highest energy requirements such as the heart muscle and liver and in those tissues that regenerate quickly such as the gums.
Whilst CoQ10 can be made in the body, production declines as we age. It has also been shown that cholesterol lowering drugs, called statins, reduce CoQ10 levels in the body, so people taking statins are increasingly recommended to take a CoQ10 supplement.
