Coenzyme Q10

Researchers are still uncovering the full extent of CoQ10's role
in our metabolism, however it is believed that CoQ10 is in
effect a biochemical spark that releases energy form food
(analogous to the spark plug of a combustion engine), as well as
a powerful antioxidant. CoQ10 is therefore involved when we
exert physical energy, and the heart is also highly reliant on
this substance.
