Does it work?

Coenzyme Q10 (CoQ10) is produced by the human body and is necessary for the basic functioning of cells. CoQ10 levels are reported to decrease with age and to be low in patients with some chronic diseases such as heart conditions, muscular dystrophies, Parkinson's disease, cancer, diabetes, and HIV/AIDS. Some prescription drugs may also deplete CoQ10 levels, such as HMG Co-A inhibitors, or statin drugs, for high cholesterol. Preliminary research suggests that CoQ10 causes small decreases in blood pressure (systolic and possibly diastolic). Low blood levels of CoQ10 have been found in people with hypertension, although it is not clear if CoQ10 deficiency is a cause of high blood pressure. Well-designed long-term research is needed.

People with Parkinson's disease tend to have low levels of coenzyme Q10, and some research has suggested it may be beneficial. However, subsequent studies have not confirmed this benefit. You can buy coenzyme Q10 without a prescription.
