Coenzyme Q10 (CoQ10)

Coenzyme Q10 (CoQ10) is a natural antioxidant synthesized by the body, found in many foods, and available as a supplement. It comes in two forms: ubiquinol, the active antioxidant form, and ubiquinone, the oxidized form, which the body partially converts to ubiquinol. Many multi-ingredient supplements contain both forms of CoQ10.

In general, coenzymes support enzymes in their various biochemical functions. CoQ10 is a vital participant in the chain of metabolic chemical reactions that generate energy within cells. It is found in every cell of the body (the name ubiquinone stems from its ubiquity), but is present in higher concentrations in organs with higher energy requirements such as the kidneys, liver, and heart.

Studies showed that approximately 14%-32% of Coenzyme Q10 was lost during frying of vegetables and eggs, but the Coenzyme Q10 content of these foods did not change when they were boiled.

Immune system cells divide more rapidly than most cells, and they are in constant need of repair and maintenance. All of this work requires energy reserves, and Co–Q10 is a critical co–factor in our energy–production pathways. In both animal and human studies, Co–Q10 has compensated for immune deficiencies caused by aging or disease.

Co–Q10 is also a very powerful antioxidant. It is made in our bodies, within a cell organelle called the “mitochondria”, and is most concentrated in the energy–demanding heart, brain and muscle systems. Unfortunately, Co–Q10 levels decrease with age (starting at 35 years).
