Coenzyme Q10


This vitamin-like substance, also known as ubiquinone,  in the body is found in large quantities in the heart, liver, kidney and pancreas.  It has been used to treat congestive heart failure, chest pain, and high blood pressure, along with other heart and blood vessel conditions.


Some believe it provides the body a boost of energy.  It transfers energy and oxygen between blood and body cells and cell components.   It has also been known to strengthen the immune system of those with HIV/AIDS, male infertility, migraine, headaches, and muscle pains.  It protects cells from damage to the membranes, its cell structures, and other substances in the body.

Forms Available

Recommended Intake

There is no solid evidence for the healthy intake needed per day but there are supplements available in tablets and capsules.  Oil-based supplements are absorbed better in the body and it may take the body one to two months for effects to be noticeable.  On average, most people may consume about 5 milligrams per day through their diet.


The elderly are at more concern for maintaining proper levels of coenzyme Q10 since its levels decrease with age.  A deficiency in coenzyme Q10 would greatly affect the heart since this organ needs high amounts of energy.  Cancer, muscular dystrophy, diabetes, obesity, and neurodegenerative disorders may develop as well due to a deficiency.

Sources in the Diet

All plant and animal cells contain coenzyme Q10.  It is made primarily in the liver and found in some food.  The main sources include meat, vegetables, fish, and vegetable oils, soybeans, sesame and canola oils.  It is naturally in all human tissues and organs.
