Coenzyme Q10 (Co Q10) is produced by the human body & is necessary for the basic functioning of cells. It is a fat soluble vitamin-like substance present in the mitochondria of all the cells in the body. Co Q10 levels decline with age. It can be naturally found primarily in fish & meat, however only in very small amounts. Co Q10 is an oil-soluble substance that is present in all forms of animal life. It is a component of the electron transport chain & participates in generating energy in the form of adenosine triphosphate (ATP). Not all forms of Co Q10 are the same, & many common varieties actually employ a synthetic form made from tobacco leaves. However, the "trans" form of Co Q10, which is processed naturally & through yeast fermentation, is identical to that produced by the body. Reflex® Coenzyme Q10® is 100% fermented from yeast creating a completely impurity free product.
