CoQ10 is a naturally occurring compound present in every cell of the body. CoQ10 is commonly known as ubiquinone and is derived from the word ubiquitous, meaning "found everywhere. Coenzyme Q10 is a nutrient that has been proven to be useful for a variety of health problems. People suffering with gum disease given CoQ10 achieve better results than those given a placebo. CoQ10 is essential for the basic functioning of cells. CoQ10 levels decrease with age and is low in patients of some chronic diseases such as muscular dystrophies, heart conditions, diabetes, Parkinson’s disease, cancer, and HIV/AIDS. CoQ10 in the body can be raised by CoQ10 supplements, although it is still not proven that reinstating "low CoQ10" is helpful.
