Due to its roles in energy production and as a powerful antioxidant Coenzyme Q10 is essential for the health of virtually all of our tissues and organs.1
CoQ10 is present in and produced by every cell in the human body. 2 It is not a coincidence that since one of CoQ10’s main roles is to assist in energy production, it is found in highest quantities in tissues with high energy turnover. This means organs which are continuously working or require the most energy such as your heart or brain contain the highest levels of CoQ10 in your body.3
CoQ10 levels in the body
As we age, our overall levels of CoQ10 gradually decrease. It is known that nearly every tissue in the body experiences a decline in CoQ10 levels including your heart, lungs, liver, blood, brain and more.4 Because of this, it is believed that this decline may play a role in many chronic diseases or those which are typically more common in older people.
Medical conditions and CoQ10
Conditions such as Alzheimer’s disease, Parkinson’s disease, certain cancers, certain heart conditions, and diabetes have all been studied looking for possible relations between levels of CoQ10 and the disease.3 Definitive links between the disease and a decrease in CoQ10 have been found in diabetes, certain cancers and congestive heart failure.4 While CoQ10 supplements are actively encouraged for some of these areas, there is still much research which needs to be done.
CoQ10 and the eye
Just like the rest of your body, the levels of CoQ10 decline in your eye as you age as well. In fact, a clinical study has shown that levels of CoQ10 in the eye, specifically the retina, may decline on average by 40% as a result of aging.4
CoQ10 the antioxidant
Even more so than other tissues in the body, CoQ10 is believed to be a powerful antioxidant in the eye.4 The eye is exceptionally vulnerable to oxidative stress (what antioxidants protect against) so maintaining or increasing levels of CoQ10 via supplementation may be useful for a variety of eye conditions.4
