CoenzymeQ10, also known as CoQ10, is a naturally occurring substance in the body that also can be taken as a supplement. The full effects of the substance are still being studied, but it is thought that CoQ10 can help reduce the risk of certain diseases and enhance immunity, among other things. Even though CoQ10 is something the body normally produces, consult a health care provider prior to taking CoQ10 supplements to avoid any adverse effects.
Function
According to MayoClinic.com, CoQ10 is a necessary enzyme for cell functioning, and the University of Maryland Medical Center adds that CoQ10 helps make adenosine triphosphate, or ATP, the major energy source of cells. It is also an antioxidant and helps protect cells from cell damage. The human body makes less CoQ10 as we age, and it usually is lower in those with Parkinson's disease, cancer, diabetes or muscular dystrophy, says MayoClinic.com.
Benefits
CoQ10 has a variety of positive effects on the body. It helps boost the immune system, provides energy and is thought to help treat certain diseases when used with drug therapies and supplements, says the University of Maryland Medical Center. Regarding heart disease, CoQ10 has been found to help reduce pain and subsequent heart attacks when it is given daily to heart attack sufferers within three days of the cardiac arrest, states the University of Maryland. CoQ10 supplements also might help reduce bad cholesterol levels and high blood pressure, as well as help control blood sugar.
Dietary Sources
CoQ10 can be found in many foods, making it easy to get adequate levels of the substance through diet. Foods relatively high in CoQ10 include meat, chicken, fish, soybean oil and nuts, says the Linus Pauling Institute. Foods containing moderate amounts of the substance are fruits and vegetables, eggs and dairy products. The University of Maryland Medical Center states that most people consume sufficient amounts of CoQ10 solely by diet, but supplements can be used with certain medical conditions.
Side Effects
As with any supplement, some people can experience side effects from CoQ10. According to MayoClinic.com, side effects are usually mild and resolve fairly quickly. They can include nausea, vomiting, upset stomach, diarrhea, rash, insomnia, headache and flu-like symptoms. CoQ10 can lower blood sugar levels as well as blood pressure, and caution should be taken by people with diabetes or hypoglycemia, and those taking blood pressure medication.
Warning
CoQ10 has the potential to interact with many medications and should not be taken without consulting a health care professional. Children under 18 should not take CoQ10 unless directed to do so by a health care professional, says the University of Maryland Medical Center.
