In brief
Coenzyme Q10 is a substance found naturally in the body, with the highest levels in the heart, liver, kidneys and pancreas. It is also sold as a supplement.
- healthdirect lists coenzyme Q10, with magnesium and riboflavin, among supplements some people take to help prevent migraine.
- A major NIH-funded study found CoQ10 did not improve symptoms in early Parkinson's disease.
How it works
CoQ10 supplements have been studied for many conditions. Research does not support the idea that CoQ10 reduces muscle pain caused by cholesterol-lowering statins, it probably has no meaningful effect on blood pressure, and research in heart failure is inconclusive.
No serious side effects have been reported, though mild side effects such as insomnia or digestive upsets may occur. CoQ10 may interact with the blood thinner warfarin and the diabetes medicine insulin, and it may not be compatible with some types of cancer treatment.
