Heart-Disease: The History And Usefulness Of Coenzyme Q10

Throughout my childhood I was aware of the importance of eating well
and taking my vitamins. But the science of dietary supplements has
come a long way since those days. And one of the stars in this
scientific progression is Coenzyme Q10 (CoQ10). CoQ10 is not a drug.
It is a vitamin-like substance that is found in small amounts in a
variety of foods and is synthesized within our body tissues.

Enzymes are compounds in the body that are absolutely essential for
the many processes necessary to keep us alive and our bodies
functioning properly. Mitochondrial enzymes are those particular
enzymes that are essential for the production of the high-energy
phosphate ATP (adenosine triphosphate) upon which all cellular
function depends. Without it our bodies shut down at the cellular
level. Coenzyme Q10 is the cofactor upon which at least three
mitochondrial enzymes depend. By logical inference then ATP
functioning depends upon CoQ10. In short, all human cellular
function depends on ATP. And ATP function depends on CoQ10.
