Every cell in your body contains Co Q10. Also known as ubiquinone, this enzyme is necessary for helping your mitochondria produce the energy that helps your body to function. Think about it; all of the jobs your body has to perform, such as breathing, thinking, digesting and pumping blood, take energy. You have to manufacture this energy from somewhere, right? Co Q10 is one part of the equation that is very important to keep your body doing what it needs to do.

Side effects fro CoQ10 are uncommon. It's also not likely that someone would take so much that they would start to experience overdose symptoms, but it's always wise to understand all aspects of any supplement you are taking.
