Coenzyme Q10 is produced by the human body and is necessary for the basic functioning of healthy living cells. It has two main physiological roles: energy production and antioxidant protection. Without coQ10, the chain of cellular energy is broken; 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. PQ-10 has the ability to be absorbed 2.5–4.25 times more efficiently than the standard ubiquinone form of coQ10.
