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. PQ10 has the ability to be absorbed 2.5-4.25 times more efficiently than the standard ubiquinone form of coQ₁₀.
