CoQ10, or coenzyme Q10, is a powerful antioxidant that is in most of the tissues in your body. A fair amount of research suggests that people with fibromyalgia (FMS) and chronic fatigue syndrome (ME/CFS) have low levels of CoQ10.
The role of coenzymes is to help convert molecules from your food into energy in the form of adenosine triphosphate (ATP), which studies show is also sometimes deficient in FMS and ME/CFS.
Low CoQ10 levels also have been linked to several neurodegenerative disorders, diabetes, cancer, and cardiovascular disease.
CoQ10 has become a common supplement for FMS and ME/CFS and has received a fair amount of attention from researchers.
