Function of Coenzyme Q10

Apr 7，2022

Coenzyme Q10 (CoQ10) is a substance that is naturally present in the human body, with the highest levels in the heart, liver, kidneys, and pancreas. It is sold in the United States as a dietary supplement. Because CoQ10 has important functions in the body and because people with some diseases have reduced levels of this substance, researchers have been interested in finding out whether CoQ10 supplements might have health benefits.

Function

Although CoQ10 plays a key role in the body, most healthy people have enough CoQ10 naturally. There is some evidence that adding more -- in the form of CoQ10 supplements -- may be beneficial. Increasing age and some medical conditions are associated with dropping levels of CoQ10. But in these cases, it’s uncertain that adding CoQ10 will have an effect.

CoQ10 has been used to treat many different conditions. There's evidence that CoQ10 supplements can lower blood pressure slightly. CoQ10 is also used to treat heart failure and other heart conditions, possibly helping to improve some symptoms and lessen future cardiac risks when combined with regular medications, but the evidence is conflicting.

Though still controversial, some preliminary evidence suggests that CoQ10 may help to prevent or treat the adverse effects, such as muscle pains and liver problems, of taking statin-type cholesterol drugs.

Preliminary studies have shown that CoQ10 may slow, but not stop, the progression of Alzheimer's disease. Additional research is needed to confirm this effect.

CoQ10 has also been studied as a preventive treatment for migraine headaches, though it may take several months to work. It has also been studied for low sperm count, cancer, HIV, muscular dystrophy, Parkinson’s disease, gum disease, and many other conditions. However, the research has not found any conclusive benefits. Although CoQ10 is sometimes sold as an energy supplement, there is no evidence that it will boost energy in a typical person.

Uses

CoQ10 is used to:

Prevent heart disease

Reduce cholesterol

Reduce muscle pain caused by cholesterol medications known as statins

Prevent migraines

Help reduce symptoms of Parkinson’s disease

Treat infertility

CoQ10 also has other uses that haven’t been studied by doctors to see if they work.

Adverse effects

There are relatively few case reports of gastrointestinal symptoms (eg, loss of appetite, abdominal pain, nausea, vomiting) and central nervous system symptoms (eg, dizziness, photophobia, irritability, headache). Other adverse effects include itching, rash, fatigue, and flu-like symptoms.
