Coenzyme Q10 (CoQ10)—Ubiquinone

Coenzyme Q10 is a substance made by our bodies and obtained in the diet, mainly in oily fish
(that also contain EPA), organ meats, and whole grains. Ubiquinone may soon be called a
fat-soluble vitamin as it is shown to be essential and also to create problems when deficient.
There are ten types of CoQ; CoQ10 is the main active one in humans, which works along with
certain enzymes to support the body’s bioenergetic functions. CoQ10 is an electron carrier
and is important to many body energy systems, particularly in the cell mitochondria, which are
known as the energy factories, where it aids in generating ATP. CoQ10 acts as a mild metabolic
stimulant and may facilitate weight loss. It also appears to be a mild immune stimulant.
This substance has been shown to help heart function by enhancing the pumping action and
electrical functioning, as well as helping to lower blood pressure. CoQ10 seems to be related
to vitamin E and is supportive of its functions, including those in the mitochondria.


Preliminary research regarding the use of coenzyme Q10 in patients with heart failure has produced very positive findings. Most of these patients describe some improvement; this supplement probably improves energy production in the heart muscle cells. It is possible that CoQ10 will be helpful in other cardiovascular functional problems, whether electrical arrhythmias or cardiac muscular dysfunction.


The amount of CoQ10 needed for effectiveness is approximately 10–20 mg. twice daily. Taking at least 600–800 IU of vitamin E daily, along with the basic nutrients, including vitamin C, niacin, and other cholesterol-lowering substances, such as EPA, is probably a good idea as well for cardiovascular problems. Look for more research and medical use for coenzyme Q10.
