Coenzyme Q10 is produced by the human body and is necessary for the basic functioning of healthy living cells. CoQ10 is also the vital catalyst in the creation of energy that cells need for life. Without coQ10, the chain of cellular energy is broken and without energy, cellular life ceases. CoQ10 levels decrease with age and are even lower in patients with chronic diseases. Prescription drugs including statins may also lower CoQ10 levels, yet they can be increased by supplementing with CoQ10.
