International Coenzyme Q10 Association
.:Definition 
Coenzyme Q10 (CoQ10) or ubiquinone is essentially a vitamin or vitamin-like substance. Disagreements on nomenclature notwithstanding, vitamins are defined as organic compounds essential in minute amounts for normal body function acting as coenzymes or precursors to coenzymes. 

.:History 
CoQ10 was first isolated from beef heart mitochondria by Dr. Frederick Crane of Wisconsin, U.S.A., in 1957 (2). The same year, Professor Morton of England defined a compound obtained from vitamin A deficient rat liver to be the same as CoQ10(3). 

.:Deficiency 
Normal blood and tissue levels of CoQ10 have been well established by numerous investigators around the world. Significantly decreased levels of CoQ10 have been noted in a wide variety of diseases in both animal and human studies. 

.:Treatment of hearth disease 
CoQ10 is known to be highly concentrated in heart muscle cells due to the high energy requirements of this cell type. For the past 14 years, the great bulk of clinical work with CoQ10 has focused on heart disease. 

.:Frequently Asked Question 
Over the past several years, there has been a steady increase in public interest and awareness of nutritional supplements and vitamins. Along with this accelerated interest has come an understandable explosion in the number and complexity of questions raised by patients about vitamins in general. 

.:The future 
In the past 50 years the driving force in medicine has been the development of drugs and procedures to modify the pathophysiology of illness. As viewed from the trenches of medical practice, the advances in drug therapy, although notable and clearly helpful, appear to have reached a plateau.
