What is Coenzyme Q10 or COQ10?

Coenzyme Q10 (CoQ10) is a vitamin-like substance that is found in every cell of the body. Cells use CoQ10 to produce energy the body needs for cell growth and maintenance. CoQ10 also functions as an antioxidant, which protects the body from damage caused by harmful molecules


What is CoQ10 used for?

The fact that CoQ10 is present in many cells across the body, tells us it could have effect on multiple organ systems. It is recommended to consult with your doctor before you take any supplements, especially if you have any chronic illnesses.

Heart Health

As the heart muscle consumes energy, it generates free radicals that can be damaging to heart tissue. CoQ10 helps the heart muscle produce energy more efficiently and also works as an antioxidant that removes the damaging free radicals. Studies have demonstrated that low levels of CoQ10 are associated with increased incidence of heart failure.

Unfortunately for those trying to prevent a first or second heart attack by lowering their cholesterol, statin based drugs (commonly used to fight high cholesterol) also deplete CoQ10 levels. CoQ10 supplements are a good way for statin drug users to replenish their bodies’ supply of this enzyme.

CoQ10 may also be beneficial for people with heart failure when combined with heart failure medications. Typically a person who has heart failure has lower levels of CoQ10.

High blood pressure

Several clinical studies involving small numbers of people suggest that CoQ10 may lower blood pressure. However, it may take 4 to 12 weeks to see any change. In one analysis, after reviewing 12 clinical studies, researchers concluded that CoQ10 has the potential to lower systolic blood pressure by up to 17 mmHg and diastolic blood pressure by 10 mm Hg, without significant side effects. More research with greater numbers of people is needed.

Other Benefits

Preliminary clinical studies also suggest that CoQ10 may:

  • Improve blood sugar in people with diabetes

  • Improve immune function in people with HIV or AIDS

  • Increase sperm motility, improving male fertility
