Coenzyme Q 10 --- known also as CoQ10 --- is a substance found in the heart, liver, pancreas and kidney that acts similarly to a vitamin and may help improve blood pressure. CoQ10 also acts as an antioxidant, helping fight off free radicals that cause cell and tissue damage throughout the body.
Function of CoQ10
One of the main functions of CoQ10 in the body is to produce an essential molecule called adenosine triphosphate, or ATP, one of the main sources of energy for your cells. CoQ10 is usually found naturally in the body, but at higher levels during a person's younger years and may diminish with time or due to smoking, according to MedlinePlus. CoQ10 can also be manufactured and is readily available as a nutritional supplement.
CoQ10 and Cholesterol
There is no direct evidence that CoQ10 can help lower cholesterol levels. However, some studies have shown that CoQ10 helped relieve the side effects of statin medication, such as muscle and joint aches. According to MayoClinic.com, however, there have not been enough conclusive studies to recommend CoQ10 as a solution to statin side effects. Those with high cholesterol tend to have depleted levels of CoQ10 in the body, according to the University of Maryland Medical Center, so taking CoQ10 supplements may be effective in helping treat the deficiency.
Other Uses
CoQ10 may have other beneficial health features, included its possible effects on high blood pressure, congestive heart failure, migraines, diabetes and gum disease. Limited studies have shown beneficial effects on these conditions by taking CoQ10 supplements. However, as with its effects on cholesterol, the actual and long-term benefits are not entirely clear, and further studies are needed to better determine its effectiveness in treating various conditions.
Side Effects
When considering taking CoQ10 as a supplement, it's important to consider the potential side effects. According to MayoClinic.com, most people don't experience side effects from taking CoQ10. However, potential side effects include upset stomach, nausea, vomiting, diarrhea and loss of appetite. According to MedlinePlus, CoQ10 has also been shown to cause skin rashes in some people.
Warnings
Talk to your doctor before taking CoQ10 in combination with statin medication for high cholesterol. Also seek the advice of your doctor if you have low blood pressure, as CoQ10 can cause your blood pressure to drop and may lead to unsafe blood pressure levels. Stop using CoQ10 at least two weeks prior to scheduled surgery. Avoid CoQ10 if you are pregnant or breastfeeding, as its effects on infants has not been determined.
