CoQ10 Facts

Coenzyme Q-10 (CoQ-10) refers to a compound that occurs naturally in the body, especially in the kidney, heart, liver and pancreas. Some people take CoQ-10 as a health supplement. Scientists identified CoQ-10 in 1957.

Features

• CoQ-10 exists in the mitochondria, the energy-producing center of the cell, and helps produce adenosine triphosphate (ATP), an energy source. CoQ-10 also functions as an antioxidant and can neutralize harmful free radicals, according to the University of Maryland Medical Center.

Efficacy

• According to the Natural Medicines Comprehensive Database scale, CoQ-10 supplements are "likely effective" in treating CoQ-10 deficiency, which occurs very rarely, and certain mitochondrial disorders. CoQ-10 supplements are "possibly effective" for lowering high blood pressure, preventing migraines, treating muscular dystrophy and treating Parkinson's disease. CoQ-10 supplements are "likely ineffective" for improving athletic performance and preventing periodontal disease. More research is needed to determine whether CoQ-10 is effective in treating or preventing other conditions.

Safety and Side Effects

• Tell your doctor if you take CoQ-10 or other health supplements. Talk to your doctor before taking CoQ-10 if you take prescription drugs. CoQ-10 may cause nausea, vomiting, diarrhea, loss of appetite or allergic skin rashes. Avoid side effects by taking smaller doses of CoQ-10 two or three times a day.
