Co-enzyme Q-10 substance is normally manufactured in the human body and is also found in minuscule amounts in almost every cell on Earth. For that reason it is also called "ubiquinone." But this vitamin has been only recently discovered, so as I write this book Co-enzyme Q-10 is not widely known.

Q-10 is essential to the functioning of the mitochondria, that part of the cell that produces energy. With less Q-10 in heart cells, for example, the heart has less energy and pumps less. The same is true of the immune system cells, the liver cells, every cell. As we age the body is able to make less and less Q-10, contributing to the loss of energy frequently experienced with age, as well as the diminished effectiveness of the immune system, and a shortened life span.

Q-10 was first used for its ability to revitalize heart cells. It was a prescription medicine in Japan. But unlike other drugs used to stimulate the heart, at any reasonable dose Q-10 has no harmful side effects. It also tends to give people the extra pick up they are trying to get out of a cup of coffee. But Q-10 does so by improving the function of every cell in the body, not by whipping exhausted adrenals like caffeine does. Q-10 is becoming very popular with athletes who measure their overall cellular output against known standards.

Besides acting as a general tonic, when fed to lab animals, Co-Enzyme Q-10 makes them live 33 to 45 percent longer!
