A favorable trend has emerged whereby researchers today are measuring blood levels of ingested nutrients to ascertain how much are really absorbed into the human body.
An example of the value of this can be seen in recent vitamin D studies. It turns out that some people only need 1,000 IU a day of supplemental vitamin D to achieve optimal blood status, whereas others require 5,000 IU to 10,000 IU daily.1-6
CoQ10 Blood Levels in Heart Failure Patients
Peter Langsjoen, MD, is considered the world’s foremost expert in the use of CoQ10 to treat cardiac disease. He conducts his research and clinical practice in Tyler, Texas.
Peter Langjoen, MD
When the ubiquinol form of CoQ10 was introduced last year, Dr. Langsjoen and his associates were curious to investigate whether it could reverse the course of advanced congestive heart failure. Along with his pioneering father, Dr. Langsjoen had observed that patients with advanced heart failure often failed to achieve adequate blood (plasma) levels, even when high doses of conventional CoQ10 were used.7
Dr. Langsjoen found that in response to the administration of 900 mg of conventional ubiquinone CoQ10, advanced heart failure patients only increased their total CoQ10 levels to less than 2 mcg/mL of blood. Congestive heart failure patients with CoQ10 blood levels as low as this respond poorly, with very little improvement in ejection fraction (a test that measures the heart’s pumping capacity).8
In healthy people, the ingestion of 900 mg of conventional (ubiquinone) CoQ10 is expected to raise total blood levels to around 3 mcg/mL. Dr. Langsjoen postulated that the reason ubiquinone fails to significantly increase CoQ10 blood levels in critically ill patients is the impaired absorption caused from the intestinal and liver edema they so often suffer.
Comparing CoQ10 Blood Levels
In order to ascertain the effects of ubiquinol, Dr. Langsjoen identified patients with advanced congestive heart failure who had been taking 450 mg/day of ubiquinone, but whose mean total plasma CoQ10 blood level was only 1.4 mcg/mL. All of these patients were then changed to 450 mg/day of ubiquinol.
The results showed that ubiquinol increased mean plasma CoQ10 levels up to 4.1 mcg/mL (or 2.92-fold greater than ubiquinone).8 A review of previous studies indicates that significant clinical benefit in heart failure patients requires a plasma CoQ10 level of around 4 mcg/mL.9-11 In severe heart failure patients, the only way these higher levels can be obtained appears to be with ubiquinol—not conventional ubiquinone CoQ10 supplements.
Comparing Improvements in Cardiac Function
The ejection fraction test assesses the heart’s pumping capacity by measuring how much blood is pumped after each beat compared with the amount of blood remaining in the heart. Healthy people have an ejection fraction of 50-75%, while those with congestive heart failure often have values below 20-30%.12
In the study conducted by Dr. Langsjoen, the ejection fraction improved from 24% up to 45% in ubiquinol-treated patients who had follow-up echocardiograms. This represented a recovery of up to 88% in this critical measurement of cardiac output. The higher blood levels of CoQ10 and the improved ejection fractions were accompanied by a remarkable clinical improvement in these heart failure patients.8
Based on the findings from this study, Dr. Langsjoen’s group concluded:
“It is our preliminary observation that ubiquinol has dramatically improved absorption in patients with severe heart failure and that the improvement in plasma CoQ10 levels is strongly correlated with both clinical improvement and improvement in measurement of left ventricular function.”8
Why Congestive Heart Failure Deaths are Increasing
Congestive heart failure currently strikes five million Americans.13 Most victims are over 65, an age when cardiac muscle CoQ10 levels are sharply depleted (by as much as 72%) compared with youth.14
Each year, about one million Americans are hospitalized because of congestive heart failure and nearly 53,000 die directly from it.15 A predicted increase in heart failure mortality can be attributed to several factors, including obesity-diabetes, more people surviving heart attacks (with heart muscle damage), and an aging population. As one can see from the chart on the next page, normal aging causes a severe depletion of CoQ10 in tissues throughout the body,14,16,17 which helps explain why older people suffer more congestive heart failure.
An even more insidious reason why more cardiac patients are dying from congestive heart failure is the prescribing of statin drugs without sufficient CoQ10 intake. Since statin drugs deplete CoQ1018 synthesis in the body, one can easily see why congestive heart failure deaths are skyrocketing in those being aggressively treated by mainstream cardiologists.
Those at high risk for heart disease (such as diabetics) and those who have survived a heart attack often need to be prescribed a statin drug to reduce additional coronary artery occlusion. These statin drug users also need to supplement with an adequate amount of CoQ10 to protect against the cardiac cell energy depletion that is the underlying cause of congestive heart failure.
Multiple Advantages of Ubiquinol Over Ubiquinone
Last year, we provided what we thought was irrefutable evidence of the multiple advantages of the ubiquinol form of CoQ10. Compared with conventional ubiquinone CoQ10, ubiquinol was shown to absorb into the bloodstream up to eight times better,20-22 reduce fatigue 90% more effectively,28 and slow aging in middle-aged mice 40% better.19
Some commercial supplement companies, however, told their customers that all they had to do was take more ubiquinone to obtain the same benefits of ubiquinol. Commercial companies had a self-serving reason for sticking with ubiquinone—their profit margins on it were significantly higher.
We at the Life Extension Foundation take a different view. Keeping our members in a youthful state of longevity is the most efficient way of maintaining the revenue stream we need to fund our scientific research projects. We had no problem reducing our margins to provide members with the clearly superior ubiquinol form of CoQ10.
Dr. Langsjoen’s remarkable findings that high-dose ubiquinone was ineffective for advanced heart failure patients, whereas ubiquinol reversed the course of the disease, provide the most conclusive evidence to date of the superiority of ubiquinol CoQ10.
Fascinating History of CoQ10
In this issue of Life Extension magazine, we publish an insider’s look at the 50-year history of CoQ10 that describes the initial skepticism and the subsequent discoveries made by scientists who fastidiously persevered against the conventional dogma of the day (see page 57). You’ll be amazed as to how much painstaking cardiovascular research went into providing us with the wealth of CoQ10 data we now have today.
We also publish in this issue, an update on new studies showing the combination of CoQ10 (and other nutrients) with conventional therapies improves treatment outcomes in advanced breast cancer and melanoma cases (see page 44). Based on the research that exists to date, you may be as startled as I am that oncologists are failing to tell certain cancer patients to take high-dose CoQ10.
Help Combat Today’s Leading Cause of Death
It is so regrettable that the major cause of death in the Western world is medical ignorance. There are five million Americans suffering from congestive heart failure today, and most of them don’t take any CoQ10. Those that do mostly take the antiquated ubiquinone form that provides very little benefit in advanced cases.
The Life Extension Foundation compiles and publishes avant-garde scientific information and first disseminates it to members. We then provide it to the world (via the Internet) at no charge. If more cardiologists paid attention to what we published last year about ubiquinol, a significant percentage of those who died from congestive heart failure in 2007 could still be alive.
