Q10 Vitamin?

Ubiquinone (Q10) is a coenzyme in electrone shuttle operations in the 
mitochondria, you are right. And you are right again: it is synthesized 
in the body. In fact, its name comes from the discovery that Q10 is 
ubiquitous in the system. Hence, by definition, it is NOT an essential 
nutrient, or vitamin for humans. People who are trying to prove that it 
is a vitamin are wrong (I will not go into my suppositions as to their 
reasons and motivations...).
