What Makes Your CoQ10 Levels Decline?

CoQ10 Levels Decline Naturally With Age

CoQ10 is endogenous to the human body – meaning that you produce it naturally and we all have it. However, our body’s natural ability to produce CoQ10 decreases as we age. From a peak at around age 21, the CoQ10 levels in most adults will drop over time, lowering by as much as sixty-five percent by the time we are 80.1

Unfortunately, the amount of CoQ10 we typically get from our regular dietary intake may not be enough to compensate for even our normal age-related decline in CoQ10 levels. For more information you can read: Are you getting enough CoQ10 from your diet?.

Other external factors, such as stress2 and a variety of medical conditions and drug interactions, may contribute to the accelerated depletion of your normal CoQ10 levels.


Cholesterol Lowering Medications – Statins – Can Reduce Your CoQ10 Levels

Statins, or by their proper name “HMG-CoA reductase inhibitors”, are the type of cholesterol management medications most often prescribed in the United States.

Research has shown that statins are helpful in reducing cardiovascular disease and mortality in those who are at risk. Statins are so popular with cardiologists and general practitioners that one in four adults between ages 40 and 75 are taking them. You probably know them better by their brand names, such as: Lipitor®, Pravachol®, Crestor®, Zocor®, etc. However, statins have an important unintended side effect, they significantly reduce your normal CoQ10 levels.3

Your body produces cholesterol in a pathway in your liver. It is within this same pathway that your body produces other essential compounds and chemicals including CoQ10.  Because statins work by blocking this pathway, they also block the production of CoQ10.  In fact, statin medications can lower CoQ10 levels by as much as 40%.



This could potentially complicate other health issues and leave you vulnerable to side effects from your prescribed statins. If you would like more information about statin side effects, you can access our FREE eBook here.

However, there is good news! The University of Maryland Medical Center (UMMC) reports that “taking CoQ10 supplements can bring levels back to normal. It further suggests that CoQ10 may support healthy cardiovascular function – something worth considering, especially if you have a history of heart health concerns in your family.
