Coenzyme Q10, or CoQ10 as it is commonly written, is a compound made by the human body and necessary for basic cell function. As we age, levels of CoQ10 decrease, often present in those with chronic illnesses such as cancer, muscular dystrophy and Parkinson's disease. It can even be low in individuals with HIV/AIDS and diabetes. Therefore a CoQ10 supplement could be used. It can be taken as a soft gel capsule, spray or tablet.
Features
Coenzyme Q10 supplements have been used to treat heart disease, high blood pressure and heart failure, high cholesterol, diabetes, periodontal (gum) disease and breast cancer.
According to the University of Maryland Medical Center, it is also being used for immune therapy, fertility enhancement, treatment for Alzheimer's disease, to enhance athletic performance, to delay the aging process and to improve skin.
It's also being used to help treat asthma, chronic fatigue syndrome, addiction to cocaine, migraine headaches and age-related macular degeneration.
Significance
The University of Maryland Medical Center says Coenzyme Q10 is found "in the energy-producing center of the cell known as the mitochondria." It helps make adenosine triphosphate, or ATP, which is a major source of energy in the body. ATP aids in muscle contraction and protein synthesis.
The University of Maryland also says CoQ10 works as an antioxidant. Antioxidants rid the body of free radicals, which can damage cells and lead to disease.
Safety
The Mayo Clinic says Coenzyme Q10 may lower blood sugar levels, so people with diabetes or hypoglycemia need to be careful. The supplement may also lower blood pressure so those with low blood pressure or who are on blood pressure medications should also be cautious.
The University of Maryland says there have been reports that CoQ10 may decrease the effectiveness of blood-thinning medications, so if you're taking Coumadin or Plavix, check with your doctor before taking a supplement.
Considerations
Some people have allergic reactions to Coenzyme Q10. You may have nausea, vomiting or an upset stomach, itchy skin, insomnia, headache or dizziness. You may also be tired or have flu-like symptoms.
Warning
The Mayo Clinic says that while supplementation of CoQ10 is used, it's "controversial as a treatment in many areas." Also, the U.S. Food and Drug Administration doesn't regulate supplements.
The National Library of Medicine says the levels of CoQ10 can be increased by taking supplements, although it's not clear whether doing so is beneficial.
