CoQ10 plays a key role in the body with most healthy humans having enough CoQ10 naturally. Coenzyme Q10 is presently in animals and most bacteria and can be found in plenty in foods like liver, whole grains, and oily fish like salmon. Evidence suggests that adding more in the form of CoQ10 supplements may be beneficial. Aging and certain medical conditions are associated with decreasing levels. CoQ10 has been used to treat a variety of conditions. Evidence shows that CoQ10 supplements can lower blood pressure. CoQ10 is also used to treat cardiovascular conditions, possibly helping to improve some symptoms and reduce future cardiac risks when combined with medications, but the evidence is conflicting. It is a component of the electron transport chain and participates in aerobic cellular respiration, which generates energy in the form of ATP. Ninety-five percent of the human body's energy is generated this way.[ Organs with the highest energy requirements like the heart, liver, and kidneys, also have the highest CoQ10 concentrations. CoQ10 has a variety of applications, commonly taken as a nutritional supplement and sometimes used in cosmetics. It may help to prevent or treat the adverse effects, such as muscle pains and liver problems, of taking statin-type cholesterol drugs. Studies have shown that it could slow the progression of Alzheimer's disease CoQ10 has also been studied as a preventive treatment for migraines, low sperm count, cancer, HIV, muscular dystrophy, Parkinson’s disease, gum disease, and many other conditions.
