Coenzyme Q10: Research confirms ubiquinone and ubiquinol are nearlyequally-absorbed ...
April 22, 2019 04:29 PM
Many Coenzyme Q10 products have labels that indicate that their product is better absorbed due to longtime beliefs surrounding ubiquinol (reduced Coenzyme Q10) being hard for the body to absorb. Many brands instead market ubiquinone, which is redox Coenzyme Q10 instead, since studies have been more supportive about this form being easier for the body to absorb. New research, however, is concluding that both of these forms are equal when it comes to the ability to be absorbed through the body.
"Marketing terms such as “better absorbed” should be questioned unless the absorption or bioavailability is actually stated. Only when the actual absorption has been verified can the better absorbed product be determined."

What Are The Benefits Of Ubiquinol Vs Regular CoQ10?
May 31, 2014 06:33 AM
In modern society, nutritional supplements have become a common method to improve health. A wide range of specific needs determines the use of different supplements, but there are a few that will work in just about everyone and improve their health.
Coenzyme Q10, commonly abbreviated to CoQ10, is one of those universally effective supplements. This vitamin-like substance offers far-reaching benefits for the human body. It has a crucial role in the body's energy maintenance and it's an extremely powerful antioxidant. This substance is naturally produced by the body, but as we get older, the organism's ability to synthesize CoQ10 weakens progressively. It is, therefore, recommended that people initiate a regular intake of CoQ10 somewhere at the adult or even young adult life stage. This is a commonly prescribed supplement for old people owing to its longevity and energy inducing benefits, but it's especially critical for those who are medicated with statin drugs because these are known to reduce CoQ10 levels in the organism. Elite athletes can also benefit from this substance to achieve higher peak power levels.
ubiquinol is the most efficient way to take advantage of this supplement because it's the fully reduced form of CoQ10 that our body actually absorbs and uses. The consumption of Ubiquinone requires our body to firstly metabolize and convert it into ubiquinol. This process limits the speed and efficiency of CoQ10 absorption, requiring larger quantities to be consumed for similar health effects, not to mention that the metabolism has a tendency to worsen with age. Ubiquinone is more widely available and is cheaper, though.
Does Ubiquinol Get Absorbed Better Than Regular CoQ10
November 06, 2013 08:52 PM
Benefits is ubiquinol
ubiquinol can be described as reduced form of CoQ10 (Ubiquinone). For an individual to benefit from the type of nutrient that is needed for producing cellular energy and reduce signs of aging, the body has to convert ubiquinone to ubiquinol. Studies have shown that it gets absorbed better than CoQ10. It is also known to reduce exercise induced fatigue by around 90% when compared with Ubiquinone. This is probably because CoQ10 has a chemical nature that undergoes “redox chemistry”. This implies that it flips back and forth between not having and having two additional electrons.
Importance of ubiquinol to Human Body
This is a very important part of the human body because it transports flow of electrons that permits chemical energy to be harnessed down a gradient. This is normally the last stage where food is converted to energy to fuel the body. ubiquinol on the other hand is the form where these extra electrons are reduced when speaking in chemistry terms. Although there is a small difference between the two, it really has big implications as this is exactly what makes it to be more absorbable in the intestines. In addition to this, the body prefers this form to perform the transport function of the blood.
It is important to note that ubiquinol was introduced to the market when Kaneka discovered techniques on how to stabilize the ingredient in 2006. From then, it has become an ingredient in numerous products. Various findings also show that it is the preferred form when it comes to ingestion. There are some studies that also show that this form is beneficial for patients who are suffering from advanced stage cardiac disorders. This is because it is absorbed much easily and also shows potential for greater clinical benefit. Manufactures are also looking into new and more advanced methods that will be used to make sure that it can be absorbed more easily than before.
What Is Ubiquinol?
August 23, 2013 02:54 PM
Coenzyme Q10 (Co10) is a naturally-occurring chemical compound in the body which fuels cell growth and enhances enzyme functions. It exists in three forms; ubiquinone (fully oxidized), semiquinone (partially reduced), and ubiquinol (fully reduced). So, ubiquinol is basically a reduced form of Co10, it is a strong antioxidant that can neutralize free radicals. Free radicals refer to a reactive and unstable atom that can trigger many medical conditions such as cardiovascular issues, weak immunity and even cancer.
ubiquinol is found in almost every organ, tissue and cell in mammals. This lipid-soluble benzoquinol can be acquired through supplementation, biosynthesis and from diet (in small amounts). ubiquinol plays an integral role in transferring electrons within the body, thereby leading to ATP synthesis. The antioxidant property of ubiquinol is very essential in the functioning of the cellular systems.
Ubiquinone is naturally converted into ubiquinol by the body to produce energy for the cells. The failure of this process can lead to insufficient energy levels in the body. The ability of the body to generate Coenzyme Q10 reduces with age and so does the ability to convert ubiquinone into ubiquinol. Therefore, older people should use ubiquinol supplements to boost their energy levels. Apart from older people, those who suffer from neurological, cardiovascular, diabetes and liver conditions may also have low ubiquinol levels.
There are many health benefits associated with ubiquinol. First, it offers a sufficient amount of energy which the heart needs to work well. It's also a strong antioxidant that protects the heart, and other vital body organs from free radicals. When it comes to energy, ubiquinol is an essential component in 95 percent of the energy produced in the body. Daily intake of ubiquinol supplement can help reduce fatigue and muscle pains; the common symptoms of insufficient Coenzyme Q10 in the body. Since ubiquinol is a strong fat soluble antioxidant, it can protect the body from oxidation, thereby providing an anti-aging benefit.
Do you feel fatigued, run down with no energy? Consider ubiquinol as a natural safe energy boosting supplement.
What Makes Ubiquinol The Best Form Of COQ10?

Benefits of ubiquinol
ubiquinol is an active antioxidant form of CoQ10. It is pre-converted and ready-to-use diet supplement. Hence, it is easily absorbed and utilized by the body. Research studies show that ubiquinol has proved to be much more effective than ubiquinone and has all vital health benefits as CoQ10.
ubiquinol is the next generation supplement which provides support for a healthy body and mind. It helps you to live a healthy life by raising your CoQ10 plasma level. It also plays an important role in production of energy levels. Moreover, it protects the cells of the body from oxidative kind of stress which can eventually damage proteins, DNA, and lipids.
Benefits of ubiquinol:
Cardiovascular health: Clinical studies show that ubiquinol improves the overall cardiovascular health. Cardiac patients who have been taking high dosages of statins like Lipitor, Zocor, etc for a long period of time have decreased levels of coenzyme Q10 as these statins inhibit the body's production level of coenzyme Q10. The low levels of CoQ10 in the body can result in cardiomyalgia, fibromyalgia, atherosclerosis, etc. Thus, if these patients take ubiquinol which is an antioxidant then it neutralizes the oxidation of LDL.
Cognitive Health: It helps to increase the stamina and energy and promotes general health and wellness.
Anti-aging support: Due to degeneration and advanced age, the aged people have less CoQ10 biosynthesis and body's conversion ability also diminishes in such subjects. A collaborated study carried out on middle aged people demonstrated that subjects who were given this supplement showed marked improvement in their physical and mental activities. Thus ubiquinol by and large promotes life extension and improves the overall mental health by compensating for the age-related conversion disability.
Power to other organs: ubiquinol plays an important role in igniting energy levels within the cells of vital organs like heart, kidneys, liver, and lungs. Thus it naturally helps you to sustain your energy levels.
Protects Cells: ubiquinol protect cells of vital organ like heart from further damage and from constant attack by free radicals.
Neuronal Health: ubiquinol benefits the neurological system and promotes brain health. Studies carried out on patients who had Parkinson's disease have proved that it reduces the functional decline in these patients.
Oral Health: ubiquinol impacts the oral health and significantly enhances the salivary coenzyme Q10 levels. It affects all aspects of mouth, teeth, lips, tongue, and salivary glands.
Renal Health: Studies show that ubiquinol gives significant renal protection to patients who have chronic kidney disease.
Your body constantly produces powerful antioxidants daily when you are young. But as you age, your body can not sustain this natural production level forever. Hence ubiquinol supplementation is important to promote overall good health. ubiquinol can be used as a dietary supplement. Its ready-to-use formula is eight times more effective as it can be readily absorbed by your body. Thus it is an ideal diet supplementation for current CoQ10 users.
At present there are no known side effects of ubiquinol, but if you are on multi-drug therapy or are already taking other supplementations, then please consult your doctor prior taking this diet supplementation ubiquinol.

Coenzyme Q10 is an important cofactor that is found in nearly every cell of the body. Coenzyme Q10 is naturally produced by the body as well as attained through the foods we eat or in supplement form. With out it, every cell in our body could not produce energy to function and we would die. Coenzyme Q10 has the capability to regenerate antioxidants, protecting cells and DNA from oxidative stress which naturally occurs in the body every day.
Some may say that coenzyme Q10 exists in only one form, but in fact this substance exists in at least three forms in the body naturally. These three forms are CoQ ubiquinone, CoQH ubisemiquinone and COQH2 ubiquinol all of which are metabolically active forms of coenzyme Q10.
Ubiquinone has been commercially available for more than 30 years normally consumed orally, but recently stable forms of ubiquinol have been made available for consumption which is of great interest by many researchers. The former ubiquinone when ingested had to be reduced by an enzymatically driven conversion from ubiquinone to ubiquinol in the digestive tract. This conversion is done by the transfer of electrons effectively reducing the coenzyme Q10 to a more usable form ubiquinol.
Once ubiquinol is produced the body can more easily manufacture ATP which is directly used by cells for cellular energy. In young individuals, 90 percent of coenzyme Q10 found in the blood is in the ubiquinol form. This being the case, the old form (ubiquinone) was less absorbable then the newer ubiquinol that can go right to work in the body. ubiquinol is considered the strongest lipid soluble antioxidant that is biosynthesized, providing an active defense against oxidative stress that damages, cells, proteins, lipids, and DNA.
Some scientists believe that cellular damage from free radicals cause our bodies to age. The older we get the less our bodies produce coenzyme Q10 which in its self is an antioxidant and restores other antioxidants in the body to fight the war against free radicals. Eating foods rich in antioxidants and or supplementing with antioxidants may slow the aging process.
With age, disease, and some prescription medications, the old form of coenzyme Q10 can not easily follow the process of absorption in the intestinal tract where it is reduced and shuttled through the lymphatic system into the circulatory system (blood). This is why ubiquinol was so highly sot after. ubiquinol is already reduced, the preferred form coenzyme Q10 the body wants to circulate and retain.
When one ages, energy levels always drop and one tends to slow down and feel tired sooner in the day, this may be because of a drop in coenzyme Q10 in the blood. Many recent studies suggest that the plasma ubiquinol ratio is reduced in response to cardiovascular disease, neurodegenerative disease, cancer, fatigue and especially in type-2 diabetes. Supplementing with ubiquinol can help restore plasma levels and boost ones energy levels and possibly slow diseases.
To sum it up, if you are over 45, suffering from a degenerative disease or cancer, feel tired and run down, or taking prescription medications, conventional coenzyme Q10 is not what you want to take to elevate plasma levels. ubiquinol is needed because the body can not adequately produce the most abundant form of coenzyme Q10 in he blood (ubiquinol). So for those who want to maintain health and wellness, look for ubiquinol in their local health food store.
Ubiquinol Reduced CoQ10
April 07, 2008 01:05 PM
ubiquinol, which is the reduced from of Coenzyme Q10 (CoQ10), has been recently added to the supplement offerings of many companies and has generated a lot of confusion along with its excitement. As a supplement, ubiquinol is somewhat new, but as a critical part of human metabolism, our knowledge of ubiquinol goes back to the discovery of CoQ10. Although CoQ10 is often thought of as a “static” nutrient in the context of nutrition, it actually interchanges between two useful states: the oxidized ubiquinone, and the reduced ubiquinol.
Coenzyme Q10 is a member of a family of important biological compounds which are referred to as ubiquinones. It is a lipophilic, water-insoluble substance, which takes part in a large array of biochemical oxidation and reduction reactions. It was first identified in 1957 as an essential component of the energy production system in cells. CoQ10 and other members of the ubiquinone family have, since then, been identified as critical metabolic compounds in a range of aerobic organisms. Because of its crucial role in metabolism, humans have the ability to make their own CoQ10, although small amounts can be obtained through diet and as supplements.
In humans, CoQ10 is found in each cell in the body, but is particularly abundant in tissues which have large energy requirements such as the heart, liver, kidneys, and skeletal muscles. Smaller amounts can be found in the brain, lungs, and intestines. There are also substantial amounts that can be found in circulation, which are most often associated with lipoprotein particles. In total, CoQ10 in a normal adult has been estimated to be between 0.5 and 1.5 grams. Inside cells, about half of the CoQ10 is found within the mitochondria, where the final steps of CoQ10 production occur.
CoQ10 which is not located in areas of the cell and are not charge with producing cellular energy can amount to about 50-60 percent of the total CoQ10 pool. CoQ10 can be found throughout cell membranes and in other cellular structures such as the nucleus, cytoplasm, and endoplasmic reticulum. Some experimentation has also concluded that, while the final steps of CoQ10 production occur in the mitochondria, it can be exported to other sub-cellular locations.
While participating in various oxidation and reduction reactions, CoQ10 is cycled between two stable states: a fully oxidized form referred to as ubiquinone, and a fully reduced form called ubiquinol. CoQ10 cycles through these oxidated/reduced forms in order to achieve its metabolic goals. The cycle of CoQ10 is simple. Ubiquinone picks up electrons and then becomes ubiquinol. ubiquinol then release its electrons and becomes ubiquinone again. Therefore, it would seem that CoQ10 has a very simple function of moving electrons, as the transfer of electrons is a fundamental step in the production of energy, the regeneration of antioxidants in cell membranes, and the construction of other important biological molecules. Each cell that is in the body needs a source of energy in order to survive. Therefore, sugars, fats, and amino acids are broken down in order to make energy.
In the mitochondria, CoQ10 is abundant, as it carries electrons to aid in the chemical reactions that burn cellular fuel and produce chemical energy to form ATP. Since substantial amounts of ATP are needed to power our cells, the importance of CoQ10 in human metabolism is easily understood. Both forms of CoQ10 are needed to transfer electrons between energy-producing reactions. Outside of the mitochondria, CoQ10 performs a slightly different role as a membrane and antioxidant. About half of the human body’s total CoQ10 pool may be functioning in this capacity. CoQ10 is one of the major antioxidant elements of the LDL particles and is also one of the first to be depleted when LDL is subjected to oxidation.
A discussion of CoQ10 would not be complete without mentioning its documented health benefits. Supplemental CoQ10 has been the subject of a lot of studies over the last half century, especially in applications for cardiovascular health. Many studies have shown benefits of CoQ10 in patients who are diagnosed with chronic heart failure, exercise-induced angina, hypertension, or those who have recently experienced infarction. There is also early evidence showing that CoQ10 may protect the heart from damage during chemotherapy, bypass surgery, or in diabetes. Aside from its cardiovascular uses, CoQ10 has been studied for its benefits in other conditions involving dysfunctions in cellular energetics, neurological degeneration, or oxidative stress damage. Although the clinical evidence for the potential benefit of CoQ10 in many of these applications shows promise, the variability in study outcomes proves it necessary to further research these areas for a more definite answer.
As we have previously seen, CoQ10 functions by cycling between two stable forms, ubiquinol and ubiquinone. This cycle results in the generation of cellular energy and the protection of membranes and lipids from oxidation. Dietary or supplemental CoQ10 also takes part in this cycle. Supplemental ubiquinol may have a distinct advantage over ubiquinone in its facility of absorption. Like many fats and lipophilic nutrients, CoQ10 is usually taken up by the intestinal electrolytes, packaged into lipid particles, and then released into the lymphatic system. From there, these particles are transferred into circulation where they are free to be transported throughout the body as needed.
The absorption of dietary CoQ10 is actually quite poor since it has limited solubility in lipids and depends on other contents of the gut. Some studies have measured that absorption is as low as 2-3 percent of the total dosage. One of the most thrilling consequences of the development of a stabilized dosage form of ubiquinol is its ability to be absorbed more efficiently than ubiquinone. There is evidence that CoQ10 must be reduced in intestinal enterocytes before the release into the lymphatic system. This, paired with absorption/reduction, may be a rate-limiting step of CoQ10 assimilation.
Dietary ubiquinol avoids this reduction reaction, and is directly available for absorption, which explains why ubiquinol-based CoQ10 supplements exhibit enhanced bioavailability over ubiquinone supplements. Preliminary studies in humans have shown that absorption of ubiquinol is at least double the absorption of ubiquinone. Comparisons of blood levels between trials also estimate the improvement in absorption to be significantly higher. Future studies are necessary to more accurately determine ubiquinol’s enhanced absorption, and what effect the patient age or medical condition may have on these results.

ubiquinol has powerful antioxidant actions in target cells *
Although ubiquinone (oxidized coenzyme Q10) and ubiquinol (reduced coenzyme Q10) are kept at a constant ratio within the body, the majority of the total coenzyme Q10 pool is made up of ubiquinol. In fact, when ubiquinone is taken orally, much of it appears to be rapidly converted into ubiquinol. 1,4 ubiquinol functions as a potent antioxidant in humans, including in low-density lipoproteins (LDLs) where it protects them from oxidative damage.1,4,5 The coenzyme Q10 molecule can be found in all membranes throughout cells.6 It appears to works in conjunction with both vitamin E and vitamin C to provide antioxidant actions throughout the body.7
Coenzyme Q10 supports mitochondria to enhance cellular energy production*
Coenzyme Q10, with its widespread distribution throughout the body, plays a crucial role in mitochondrial physiology as a critical member of the electron transport chain. This transport chain, which is part of cellular respiration, leads to the formation of adenosine triphosphate (ATP), our body’s primary energy source. Levels of this key nutrient may decline as a healthy person ages.7,8 Animal studies have found that supplementation can restore normal levels in certain tissues 6, and human studies suggest that supplementing with this enzyme may have increased benefits when a person has depleted levels. 7
Coenzyme Q10 supports healthy heart functioning*
Concentrations of coenzyme Q10 are understandably high in the heart as these muscle cells require high levels of energy to constantly function optimally. A number of studies (both animal and human) strongly suggest that coenzyme Q10 supplementation is supportive for healthy heart functioning and for maintaining cardiovascular system health.7,9
ubiquinol has been studied for safety and bioavailability in humans*
A recently published single-blind placebo-controlled study in healthy subjects found no safety concerns in people who took Kaneka’s QH ubiquinol supplement orally at doses of up to 300 milligrams daily for up to four weeks.4 Single oral doses of either 150 milligrams or 300 milligrams were given to fifteen healthy men and women, and standard laboratory testing (including hematology, blood chemistry, and urinalysis) as well as physical examination and electrocariography (EKG) results showed no clinically significant changes when tested two days after supplementation as compared to before the taking the supplement. In addition to the single dose study, 80 healthy volunteers were given either placebo, 90, 150 or 300 milligrams of ubiquinol each day for four weeks, and again no clinically significant differences were seen in any of the testing parameters after two and four weeks of supplementation, nor were there differences two weeks after discontinuation of the supplement. By monitoring levels in the blood, the authors found that ubiquinol was well absorbed.4
Studies in several animals also reveal no concern of toxicity in doses of ubiquinol up to 200 milligrams per kilogram of body weight for up to thirteen weeks.4 When compared to humans, this dose level is enormously higher than the recommended doses. Supplementation with ubiquinol appeared to be safe at even higher levels (up to 600 milligrams per kilogram body weight) in a study using a different animal. In vitro assays additionally found no safety concerns for the use of ubiquinol, as it was found to be non-mutagenic and did not cause damage to chromosomes in cells.
Suggested Adult Use: Take one softgel daily with food, or as directed by a nutritionally informed physician.

Active Coenzyme Q10
July 07, 2007 01:30 PM
The benefits of Coenzyme Q10 have become increasingly well-known. This important nutrient has been shown in clinical trials to improve heart function, reduce the side effects of certain drugs used to treat cancer, and slow the progression of serious brain diseases such as Parkinson’s disease. Now research has opened a new chapter in the CoQ10 story, highlighting the benefits of ubiquinol, the active form of CoQ10, to increase energy and stamina, and reduce some of he physical signs of aging.
In this issue of Ask the Doctor we will review the benefits of Coenzyme Q10, and discuss the differences between CoQ10 and its active form –ubiquinol.
Q. What is CoQ10?
A. CoQ10 is a natural, fat-soluble nutrient present in virtually all cells. CoQ10 also is known as ubiquinone. That’s because CoQ10 is ubiquitious and exists everywhere there is life. CoQ10 is vital to adenosine triphosphate (ATP) production. ATP is the energy-rich compound used for all processes requiring energy in the body. Although CoQ10 is produced by the body and exists in some limited dietary sources, these levels may be insufficient to meet the body’s requirements. CoQ10 levels diminish with age and as a result of dietary inadequacies and various disease states. Also, some drugs, especially a group of cholesterol lowering prescription drugs known as “statins,” (Pravachol, Zocor, Lipitor, etc.) significantly reduce CoQ10 levels in the body.
Q. What is ubiquinol? Is it the same or different from CoQ10?
A. ubiquinol and CoQ10 are very closely related. Ubiquinone, or CoQ10, is the oxidized form of the molecule. This means it has to be converted to a non-oxidized form before it can perform its work. ubiquinol is the active form of this nutrient. Our bodies convert CoQ10 to ubiquinol – which is the form needed to produce cellular energy. Until recently, it was not possible to use ubiquinol as a supplement because it is very unstable outside the human body. But research has now found a way to keep this molecule stable so it can be successfully taken in supplement form.
Q. If CoQ10 gets converted to ubiquinol anyway, can’t I just take CoQ10?
A. While it is true that our bodies can convert CoQ10 to ubiquinol, it isn’t true that we all do this equally well. In fact, as we age, our ability to convert CoQ10 to ubiquinol declines. And some people even have a gene that makes them less effective at this conversion than the majority of the population. IN fact, several common health issues have been associated with less than optimal ratios of CoQ10 to QH. For healthy people the ideal ratio is approximately 97% ubiquinol to 3% CoQ10. But in people with diabetes, for example, the ratios have been found to range from 43% ubiquinol to 47% CoQ10 in mild diabetes, to only 24% ubiquinol to 76% CoQ10 in severe diabetes. These numbers are for men; the numbers for women vary by 2 to 5 percentage points.
So for older folks, the 30-50% of people who have the gene that impairs CoQ10 conversion, or for people who have serious health concerns, supplementing with ubiquinol instead of CoQ10 might be the smart choice.
Q. What are the health benefits of CoQ10 and ubiquinol?
A. There have been many studies showing that CoQ10 is beneficial in treating and preventing heart disease and conditions such as high blood pressure atherosclerosis (hardening of the arteries), angina, and congestive heart failure (CHF). It’s been shown that heart attacks tend to occur when CoQ10 levels are low in the body. Exciting new research has found that CoQ10 in a unique delivery system supplementation may slow the progression of symptoms associated with neurological diseases such as Parkinson’s disease, ALS, Huntington’s disease and Alzheimer’s disease.
In addition, CoQ10 is beneficial for diabetes, immune dysfunction, cancer, periodontal disease, prostate cancer, and neurological disease. While the research on ubiquinol is still very new, it is reasonable to expect that its benefits will be equal to or perhaps even better than CoQ10, because it is the more active form.
Q. Why is CoQ10 especially important for preventing and treating heart disease, and for neurological diseases like Parkinson’s disease?
A. The heart and brain are some of the most metabolically active tissues in the body. Both require large amounts of uninterrupted energy, which means these tissues also need increased amounts of ubiquinol. Research has shown that many people with heart of brain diseases have serum CoQ10 levels that are lower than those of healthy people. Correcting such deficiencies often can produce significant results. However, these diseases become more common as we age – right at the time our ability to convert CoQ10 to its active form, ubiquinol, declines.
Q. How might ubiquinol be important for the heart?
A. Heart Health: A study on patients admitted to the hospital with an acute myocardial infarction (AMI) found that CoQ10 can provide rapid protective effects in patients with a heart attack if administered within three days of the onset of symptoms. Seventy-three patients received CoQ10 (120 mg/d). The study’s control group consisted of 71 similarly matched patients with acute AMI. After treatment, angina pectoris (severe chest pain signifying interrupted blood flow to the heart), total arrhythmias (dangerously irregular heartbeats), and poor function in the left ventricle (the essential chamber of the heart) were significantly reduced in the CoQ10 group compared to the placebo group. Total deaths due to sudden cardiac failure and nonfatal heart attacks also were significantly reduced in the CoQ10 group compared with the placebo group.
In another study, CoQ10 was studied in 109 patients with high blood pressure (hypertension). The patients were given varying doses of supplemental CoQ10 with the goal of attaining a certain blood level (greater than 2.0 mcg/l). Most patients were on medications to treat hypertension. Half the patients were able to stop taking some or all of their prescription drugs at an average of 4.4 months after starting CoQ10. The 9.4% of patients who had echocardiograms, performed both before and during treatment, experienced a highly significant improvement in heart wall thickness and function. This improvement was directly attributed to CoQ10 supplementation.
Congestive heart failure (CHF) is a debilitating disease that affects 5 million people in the
And Neurological Health?: A study sponsored by the National Institutes of Health showed that supplementing with CoQ10 in a unique delivery system was associated with a slowing of the progression of Parkinson’s disease. Participants were divided into 4 groups and their physical skills (coordination, walking, etc) and mental skills were evaluated. Each group then received 300 mg, 600 mg, or 1200 mg of a special form of chewable CoQ10, or a placebo. The researchers evaluated the participants after 1, 4,8, 12, and 16 months of treatment. Each participant was again scored on motor, mental, and activities of daily living skills.
The results of the study showed that the people who took the highest dosage of CoQ10-1200 mg-experienced the least decline in their physical abilities. The results were so encouraging that the researchers will be continuing with new studies, suing higher dosages to see if the results can get even better.
Huntington’s disease (HD) is a devastating and degenerative inherited disease that is always fatal. In fact, no other medication, drug, or nutritional supplement has ever been shown to cause a decline in the progression of this terrible disease. A study compared CoQ10 against remacemide (an investigational HD drug made by AstraZeneca Pharmaceuticals), in 347 HD patients who were in the early stages of the disease. Remacemide blocks glutamate, the neurotransmitter scientists think may cause the death of brain cells that occurs in Huntington’s disease. While remacemide had no effect on the progression of HD, CoQ10 showed a trend toward slowing the disease by an average of 15%. This meant the HD group taking CoQ10 was able to handle every day activities of life a little longer than the patients taking remacemide or a placebo. They also were able to focus their attention better, were less depressed, and less irritable.
The 15% slowing of decline can result in about one more year of independence of HD patients. Needless to say, the gift of an additional year of health in the lives of HD patients is incredibly significant.
Because of these impressive results, researchers are hopeful that supplemental CoQ10 will have beneficial effects for people with other neurological diseases such as ALS and Alzheimer’s disease, too. Studies are under way to confirm these effects.
Using the active form of CoQ10 helps to assure that, regardless of age or illness, the CoQ10 can have the greatest impact.
Q. What have been the results of research studies with ubiquinol?
A. One of the most interesting effects of ubiquinol that has been reported so far is its ability to slow the physical signs of aging. In laboratory studies, administration of stable ubiquinol to mice forestalled the changes associated with aging – rounded spine, patchy fur and irritated eyes. While the mice who received ubiquinol did not necessarily live longer than the mice that didn’t, they lived better. But it is important to note that these mice were bred to die at a young age. Human studies are needed to determined true impact on longevity.
Additionally, supplemental, stable ubiquinol has been shown to increase physical energy and stamina. In an animal study, the length of time rats were able to run on a treadmill before getting tired was measured. The same rats were then given ubiquinol and the treadmill test was repeated. The length of time the rats were able to run before tiring increased 150 times.
Q. How can one supplement have applications for neurological diseases, heart health, and even the immune system?
A. Supplements often have more than one function, especially when it’s a substance like CoQ10, which is present in all parts of the body. All nucleated cells (most cells other than red blood cells) have mitochondria and all cells require energy to function. CoQ10 is vital to ATP production. Thus, CoQ10 has applications not only in neurological (neurons or nervous system cells) and cardiac health (myocardium or heart tissue), but also for the immune system.
Q. Should I take CoQ10 or ubiquinol? How much should I take?
A. While everyone can benefit from CoQ10 or ubiquinol supplementation, it appears that ubiquinol should be the first choice for older adults, people with known genetic inefficiencies in converting CoQ10 to ubiquinol, and for people with serious heart disease or neurological diseases such as Parkinson’s disease, who are otherwise supplementing with high levels of CoQ10. For people in overall good health, a high quality CoQ10 supplement with proven absorption is a good choice.
Take 200 to 300 mg of CoQ10 or 100 mg ubiquinol daily, depending on your health history. The safety of both forms has been tested, and no significant side effects reported. Occasional mild stomach upset may occur. Taking your CoQ10 or ubiquinol with meals usually alleviates this rare effect.
