Coenzyme Q10 is a compound that is found naturally in the body and aids enzyme function and fuels cell growth. People over the age of 40 may experience difficulty in naturally producing and metabolizing coenzyme Q10 and a supplement may be recommended. There are two basic types of coenzyme Q10: ubiquinone and ubiquinol. Ubiquinone coenzyme Q10 is an oxidized form, and ubiquinol coenzyme Q10 is a reduced form and has antioxidant properties that are able to neutralize free radicals. A free radical is an atom that is reactive and unstable and has the potential to create a number of medical problems such as compromised immune system, cardiovascular issues and even cancer.

The body naturally converts ubiquinone into ubiquinol to generate energy to the cells. If this process does not take place the body's energy levels will not be sufficient. People in their 20s are able to metabolize coenzyme Q10 more efficiently than someone in their 40s or 50s and as such a regular coenzyme Q10 supplement should be sufficient. For those that are a little older, ubiquinol coenzyme Q10 may be more beneficial.


Ubiquinol coenzyme Q10 was only made available for purchase once scientists had found a suitable delivery system so that the ubiquinol was not oxidized in the air. It is typically found in gel cap form and for those that are older, a starting dosage of 200 mg a day is recommended. The blood plasma levels tend to even out after about two weeks and the dosage can be lowered to 100 mg a day as a maintenance regimen. A ubiquinol coenzyme Q10 supplement typically comes in 50 mg, 100 mg and 200 mg batches. They can be purchased as instant or time release formulas.

There are a number of health benefits that may be gained when taking this supplement. Medications such as cholesterol lowering statins can deplete the body’s production of coenzyme Q10. These drugs may also cause muscle aches in some patients and ubiquinol coenzyme Q10 will help to build up levels again. People that experience side effects such as muscle aches from taking statins should immediately inform their doctor.

Some side effects that could be experienced when taking ubiquinol coenzyme Q10 may include headaches, nausea and stomach disorders. Allergic reactions are rare and usually limited to the delivery methods rather than the coenzyme Q10 itself. People suffering from diabetes and taking insulin may need to adjust their dosage as the supplement has the potential to lower blood sugar levels. Those taking high blood pressure drugs may also need to adjust the dosage of ubiquinol coenzyme Q10.

The benefits of taking Q10 alongside statins have not been shown. If the theory that Q10 deficit is the cause for the muscle issues are true, then it would of course be a good idea to take Q10 when you experience muscle weakness on statins. But there seems to be no proven reduction in statin side effects with Q10 consumption.

It should be safe to try, though.
