CoQ10 and Cholesterol

Statin drugs are shown to affect your body's natural CoQ10 levels, making supplementation an ideal way to support this vital enzyme.

The effectiveness of the HMG-CoA reductase inhibitor drugs, the so-called “statins,” in lowering serum cholesterol concentration cannot be denied. However, CoQ10 production and cholesterol synthesis share the same biochemical pathway. As could be predicted from these pathways in the liver effectively blocking cholesterol production can also lead to blocking CoQ10 production. Numerous studies have proven this to be the case.^14,15

The results of this drug-induced mild CoQ10 deficiency is not without harm – it is associated with damage to hard-working muscles. These potentially detrimental effects have been reported in several journals.^16,17 In terms of the side effects of statin therapy, published studies have found fundamental derangements in muscle cell metabolism with exposure to statins.¹⁸ Several recent reports indicate that these drugs impact the nerves that communicate with muscles in addition to affecting the mitochondria of all muscles, including the heart muscle.^19,20 Depleted levels of CoQ10 could play a major role in these side effects of statin drugs.

The good news – dietary supplementation with CoQ10 may help overcome the potential interference of statin drugs with CoQ10 metabolism.²¹ And CoQ10 is very safe – amounts of up to 3000 mg daily are considered safe.²²

Thus, if you choose to use cholesterol-lowering medication to protect your heart and circulatory system, don’t be counterproductive. Really protect yourself – supplement with CoQ10 to replenish what you lose with the use of statin drugs. Add this vital nutrient to your Healthy Heart program.
