Q10 is a key element in the cellular energy turnover and also serves as a protective antioxidant. The human body is able to make most of its own Q10 but as we grow older, our endogenous Q10 synthesis decreases, and this is also the case with certain diseases and as a result of using specific types of medicine. A large meta-analysis has shown that Q10 supplementation is able to reduce chronic fatigue in healthy individuals as well as in people with diseases. Apparently, taking larger doses for longer periods of time works best for energy levels. It is important to choose a Q10 supplement that has the right quality and comes with documentation to ensure that the Q10 molecules are absorbed properly in the blood and reach the energy-producing powerhouses of the cells.
