In 1957, Professor Frederick Crane and colleagues discovered CoQ10 from beef heart mitochondria at the University of Wisconsin-Madison Enzyme Institute.15 R.A. Morton, from the United Kingdom, isolated the compound in rat liver just after Dr. Crane’s discovery. It was Morton who named the compound ubiquinone, meaning ubiquitous quinone or one that “exists everywhere.” 3,6 Scientists at Merck synthesized CoQ10 in 1958. In 1962, Peter D. Mitchell, PhD from University of Edinburgh determined how CoQ10 produces energy at the cellular level and in 1978 he was awarded the Nobel Prize for chemistry based on his discovery.6
The safety of escalated doses of CoQ10 has been evaluated in a randomized, placebo-controlled trials in patients with early Parkinson’s disease.9 A total of 80 patients received doses of 300 mg to 1200 mg per day of CoQ10 for up to 16 months, and there was no difference in the incidence of drug-related toxicities between the placebo and treatment arms.19 The observed safe level (OSL) is intake up to 1,200 mg/day. However, the usual dose is 100-200 mg/day in deficiency states and other disease states.13 The Institute of Medicine at the National Academy of Sciences has not established a Dietary Reference Intake, or DRI, nor Tolerable Upper Intake Level (UL) for CoQ10.2

A diet high in coenzyme Q10 intake levels can help in the prevention of cardiovascular diseases (arrhythmia, angina, heart attack, mitral valve prolapse, high blood pressure, coronary artery disease, atherosclerosis and congestive heart failure). CoQ10 helps to restore the power of Vitamin E, improve overall cellular energy levels and helps to provide assistance with blood sugar stability.2 CoQ10 regulates glucose levels throughout a lessening of oxidative stress.10 CoQ10 levels decrease with age and may be low in people with cancer, diabetes, various heart conditions, HIV/AIDS, muscular dystrophies, Parkinson’s disease and certain other genetic disorders. Some prescription drugs may also lower CoQ10 levels.1
Since the discovery of the chemical structure in 1957 there have been nearly 5,000 research studies on coenzyme Q10.2 While considerable research efforts have been put forth in the examination of this molecule, if we are going to change the landscape in acceptable use for CoQ10, more large, double-blind, placebo controlled research studies will certainly need to be conducted. This will be the only way to put CoQ10 on the map with current pharmaceutical options for treatment of conditions like hypercholesterolemia, hypertension, Parkinson’s disease, migraines, periodontitis and many others. Researchers are working hard to uncover the scientific data to support proper dosages for each of the conditions studied. The pairing up of CoQ10 with other beneficial and synergistic nutrients could be another key to unlocking its full potential in standard nutritional medicine.
Be aware though, some CoQ10 and Ubiquinol (a reduced form of CoQ10) products on the market are much better and effective than others. We can help you with the brands that we have had experience using. Remember though that CoQ10/Ubiquinol doesn’t work by itself. It also needs minerals like magnesium and vitamins like Vitamin E and D and B vitamins. We always recommend getting a thorough evaluation with blood testing to make sure that something important is not being missed. After all, most disease and problems show up in the blood long before you have symptoms. Call our office today for a consultation and testing to make sure you are as healthy as possible and ask us about Ubiquinol and CoQ 10.
