Q10 is a lipid-soluble coenzyme that is found in all the body's cells, except for the red blood cells. Carbohydrate, fat, and protein get converted into energy by means of Q10 and the oxygen we breathe. This process takes place inside the small, cellular power stations called mitochondria. To begin with, Q10 contributes to storing the energy in a chemical form called ATP (adenosine triphosphate). After that, Q10 makes sure that the energy is released in step with the shifting energy requirement of the cells.
