Coenzyme Q10 (also known as ubiqinone) is a vitamin like substance which plays a vital role in the bodys energy supply mechanism, acting in conjunction with enzymes (hence the name coenzyme Q10) to convert sugars and fat into energy. Coenzyme Q10 is also important as an antioxidant within the body. Coenzyme quinones occur in several chemical forms, with coenzyme Q10 being the only form found in human tissues.
The human body is able to synthesize (in the liver) a limited amount of coenzyme Q10, with the remainder being obtained from the diet. Rich sources of coenzyme Q10 include fish (mackerel, salmon, sardines) and nuts. Under normal circumstances, the body is able to maintain adequate levels of coenzyme Q10. However, coenzyme Q10 levels decrease with age, and are depleted by intense physical exercise or illness. Coenzyme Q10 levels are also depleted in patients prescribed cholesterol-lowering statin drugs.
