We conclude that Coenzyme Q10 has a protective effect on the brain from infarction and atrophy induced by ischemic injury in aged and susceptible transgenic mice.
Anti-aging and longevity
Coenzyme Q10 protects from aging-related oxidative stress and improves mitochondrial function in heart of rats fed a polyunsaturated fatty acid (PUFA)-rich diet.
J Gerontol A Biol Sci Med Sci. 2005.
Coenzyme Q10 supplementation on age-related changes in oxidative stress and function of heart mitochondria in rats fed a polyunsaturated fatty acid (PUFA)-rich diet was investigated. Two groups of rats were fed for 24 months on a PUFA-rich diet, differing in supplementation or not with coenzyme Q10. Animals were killed at 6, 12, or 24 months. Fatty-acid profile, hydroperoxides, alpha-tocopherol, coenzyme Q, catalase and glutathione peroxidase activities activity were measured. Coenzyme Q10-supplemented animals showed lower hydroperoxide levels; higher content and/or activity of alpha-tocopherol and catalase; and a slightly lower decrease in mitochondrial function. According to that, previously reported positive effects of coenzyme Q10 supplementation on the life span of rats fed a PUFA-rich diet might be a consequence, at least in part, of a lower oxidative stress level and perhaps, to a minor extent, of a smaller decrease in mitochondrial function.
Coenzyme Q10 may be beneficial in diabetics. It helps improve the function of endothelial cells lining blood vessels and may slightly help with blood sugar control.
Minerva Gastroenterol Dietol. 2013. The effect of coenzyme Q10 supplementation on metabolic status of type 2 diabetic patients. Diabetic patients have reduced coenzyme Q10 level. In this study we sought to compare the effect of coenzyme Q10 versus placebo on glycemic control and lipid profile in type 2 diabetic patients. In a randomized double-blind placebo-controlled trial, 64 type 2 diabetic patients were randomly assigned to receive either 200 mg Q10 or placebo daily for 12 weeks. Fasting blood samples were obtained and fasting plasma glucose (FPG), HbA1c, total cholesterol (TC), triglycerides (TG), LDL-C and HDL-C were measured. In this study no significant differences considering age, body mass index (BMI), diabetes duration, FPG, HbA1c, TC, TG, LDL-C and HDL-C were shown between two groups. Serum HbA1C concentration decreased in the Q10 treated group with no significant effect in the placebo group. Following intervention no differences have been shown regarding FPG, TG and HDL-C in Q10 treated group. Furthermore, mean differences of TC and LDL-C level were statistically altered between two groups. In this study, Q10 treatment improved glycemic control, total and LDL cholesterol but these differences were associated with no favourable effects on TG and HDL-C.
Exercise and physical activity
The Effects Of Coenzyme Q10 Supplementation on Performance During Repeated Bouts of Supramaximal Exercise in Sedentary Men.
J Strength Cond Res. 2009.
The objective of this study was to determine the effects of oral coenzyme Q10 supplementation on performance during repeated bouts of supramaximal exercise. This randomized, double-blind, crossover study was composed of two 8-week periods of supplementation with either 100 mg.d CoQ10 or placebo. Fifteen healthy and sedentary men participated in the study. According to our results, CoQ10 may show performance-enhancing effects during the repeated bouts of supramaximal exercises and CoQ10 might be used as ergogenic aid.
In a small trial of patients with recent myocardial infarction, Coenzyme Q10 -- used in addition to aspirin and cholesterol-lowering drugs -- decreased the likelihood of further cardiac events for at least one year after the heart attack. The dosage of Coenzyme Q10 used in the study was 60 mg twice daily.
Effect of coenzyme Q10 on risk of atherosclerosis in patients with recent myocardial infarction.
Singh RB,. Mol Cell Biochem. 2003.
Medical Hospital and Research Centre, Moradabad, India
In a controlled trial, the effects of oral treatment with coenzyme Q10 120 mg/day were compared for 1 year, on the risk factors of atherosclerosis, in 73 (coenzyme Q10, group A) and 71 (B vitamin group B) patients after acute myocardial infarction. After 1 year, total cardiac events including non-fatal infarction and cardiac deaths were significantly lower in the intervention group compared to control group. The extent of cardiac disease, elevation in cardiac enzymes, left ventricular enlargement, previous coronary artery disease and elapsed time from symptom onset to infarction at entry to study showed no significant differences between the two groups. Plasma level of vitamin E and high density lipoprotein cholesterol showed significant increase whereas thiobarbituric acid reactive substances, malondialdehyde and diene conjugates showed significant reduction respectively in the coenzyme Q10 group compared to control group. Approximately half of the patients in each group were receiving lovastatin (10 mg/day) and both groups had a significant reduction in total and low density lipoprotein cholesterol compared to baseline levels. It is possible that treatment with coenzyme Q10 in patients with recent MI may be beneficial in patients with high risk of atherothrombosis, despite optimal lipid lowering therapy during a follow-up of 1 year. Adverse effect of treatments showed that fatigue was more common in the control group than coenzyme Q10 group.
One study shows significant improvement in functional status, clinical symptoms, and quality of life in end stage heart failure patients.
Coenzyme Q10 improves the functional capacity of patients with chronic heart
failure, along with strengthening of their heart. Dr. Romualdo Belardinelli, of
Lancisi Heart Institute, Italy, and colleagues studied 23 patients, average age
59 years, with moderate to severe heart failure. They were assigned to 4 weeks
each of oral Coenzyme Q10 supplements or inactive placebo pills, with or without
supervised exercise training five times per week. Supplementation with Coenzyme
Q10 led to a significant 3 percent increase in HDL ("good") cholesterol and
improvement in peak exercise capacity. There was an increase in cardiac function
with Coenzyme Q10 treatment. Combining exercise training with CoQ10 produced
more marked improvements in these and all other parameters.
The researchers conclude that oral Coenzyme Q10 improves several aspects of heart failure without any side effects. European Heart Journal, November 2006.
High blood pressure, hypertension
Coenzyme Q10 may help lower blood pressure by a small amount.
Randomized, double-blind, placebo-controlled trial of
coenzyme Q10 in isolated systolic hypertension.
South Med J. 2001.
Increasing numbers of the adult population are using alternative or complementary health resources in the treatment of chronic medical conditions. Systemic hypertension affects more than 50 million adults and is one of the most common risk factors for cardiovascular morbidity and mortality. This study evaluates the antihypertensive effectiveness of oral coenzyme Q10, an over-the-counter nutritional supplement, in a cohort of 46 men and 37 women with isolated systolic hypertension. We conducted a 12-week randomized, double-blind, placebo-controlled trial with twice daily administration of 60 mg of oral coenzyme Q10 and determination of plasma coenzyme Q10 levels before and after the 12 weeks of treatment. The mean reduction in systolic blood pressure of the coenzyme Q10 -treated group was 17 +/- 7.3 mm Hg. None of the patients exhibited orthostatic blood pressure changes. Our results suggest coenzyme Q10 may be safely offered to hypertensive patients as an alternative treatment option.
Efficacy of coenzyme Q10 in migraine prophylaxis: a randomized controlled trial.
Neurology. 2005 .
Riboflavin, which improves energy metabolism similarly to coenzyme Q10, is effective in migraine prophylaxis. We compared Coenzyme Q10 (3 x 100 mg/day) and placebo in 42 migraine patients in a double-blind, randomized, placebo-controlled trial. Coenzyme Q10 was superior to placebo for attack-frequency, headache-days and days-with-nausea in the third treatment month and well tolerated; 50%-responder-rate for attack frequency was 14.4% for placebo and 47.6% for Coenzyme Q10 (number-needed-to-treat: 3). Coenzyme Q10 is efficacious and well tolerated.
Int J Biochem Cell Biol. 2014 Feb 2. Coenzyme Q10 as a therapy for mitochondrial disease. Treatment of mitochondrial respiratory chain (MRC) disorders is extremely difficult, however, coenzyme Q10 and its synthetic analogues are the only agents which have shown some therapeutic benefit to patients. It serves as an electron carrier in the MRC as well as functioning as a potent lipid soluble antioxidant.
Statin drug and coenzyme q10 deficiency
Statin drugs, such as Lipitor and Zocor, lower cholesterol levels, but at the same time they interfere with the making of coenzyme Q10 in the body. Scientists now suspect that Coenzyme Q10 deficiency as a result of stating drug use may partly, or fully, contribute to the development of muscle damage. Dr. Giuseppe Caso and colleagues from Stony Brook University, Stony Brook, New York gave 100 mg of Coenzyme Q10 for one month to 32 patients using statins. Pain intensity decreased by 40% after a month of Coenzyme Q10 treatment whereas patients treated with vitamin E (as placebo) experienced no change in pain intensity. Sixteen of 18 coenzyme Q10-treated patients experienced a decrease in pain. Am J Cardiol 2007.
My comments: I am not sure 100 mg of Coenzyme Q10 is needed in the long run. If 30 mg or 50 mg works for you, then take these lower amounts. Researchers often have a limited time to do a study and use high dosages of a medicine to elicit a response, but that does not mean that same dosage should be used forever.
Intern Med J. 2015. Potential role of coenzyme
Q10 in facilitating recovery from statin-induced rhabdomyolysis. Muscle tissue
damage is a serious complication of statin therapy. We report a case where
coenzyme Q10 facilitated recovery from statin-induced rhabdomyolysis and acute
renal failure, which had initially persisted despite statin cessation and
haemodialysis. This observation is biologically plausible due to the recognised
importance of coenzyme Q10 in mitochondrial bioenergetics within myocytes, and
the fact that statins inhibit farnesyl pyrophosphate production, a biochemical
step crucial for coenzyme Q10 synthesis. Coenzyme Q10 is generally well
tolerated, and may potentially benefit patients with statin-induced
This nutrient is beneficial in cardiovascular conditions and will likely be found to play some positive role in cognitive or neurodegenerative disorders, but more studies are needed. It would seem appropriate to supplement with this nutrient as part of a long-term health regimen, particularly for those with cardiovascular conditions. Long-term therapy with 10 to 30 mg seems to be a reasonable option for many individuals. Although it is better absorbed in an oil matrix, for practical purposes it makes little difference whether the coenzyme q10 is in oil or a capsule. Most of the coenzyme q10 capsules ranging from 30 to 100 mg provide more than adequate daily need.
South Med J. 2016. Coenzyme Q-10 in Human Health: Supporting Evidence? Coenzyme Q-10 (CoQ10) is a widely used alternative medication or dietary supplement and one of its roles is as an antioxidant. It naturally functions as a coenzyme and component of oxidative phosphorylation in mitochondria. Decreased levels have been demonstrated in diseased myocardium and in Parkinson disease. Farnesyl pyrophosphate is a critical intermediate for CoQ10 synthesis and blockage of this step may be important in statin myopathy. Deficiency of CoQ10 also has been associated with encephalomyopathy, severe infantile multisystemic disease, cerebellar ataxia, nephrotic syndrome, and isolated myopathy. Although supplementation with CoQ10 has been reported to be beneficial in treating hypertension, congestive heart failure, statin myopathy, and problems associated with chemotherapy for cancer treatement, this use of CoQ10 as a supplement has not been confirmed in randomized controlled clinical trials
Coenzyme Q10 Absorption
Effect on absorption and oxidative stress of different oral Coenzyme Q10 dosages and intake strategy in healthy men.
In a randomized, double blind, placebo controlled trial 60 healthy men, aged 18-55 years, were supplemented with various dosages and dose strategies of coenzyme Coenzyme Q10 soft oil capsules (Myoqinon 100 mg, Pharma Nord, Denmark) or crystalline 100 mg Coenzyme Q10 powder capsules or placebo. After 20 days blood levels were compared and oxidative load parameters, malondialdehyde (MDA) and thiobarbituric acid reactive substances (TBARS) were monitored to evaluate bioequivalence. All the subjects were advised to take the capsules with meals. Serum concentrations of Coenzyme Q10 (average for groups) increased significantly 3-10 fold in the intervention groups compared with the placebo group. Serum response was improved with a divided dose strategy. TBARS and MDA were in the normal ranges at baseline. After 20 days intervention in the 200 mg group TBARS and MDA decreased, but the decrease was only significant for MDA (Fig. 2). Conclusions: All supplementations increased serum levels of Coenzyme Q10. Coenzyme Q10 dissolved in an oil matrix was more effective than the same amount of crystalline Coenzyme Q10 in raising Coenzyme Q10 serum levels. 200 mg of oil/soft gel formulation of Coenzyme Q10 caused a larger increase in Coenzyme Q10 serum levels than did 100 mg. Divided dosages (2 x 100 mg) of Coenzyme Q10 caused a larger increase in serum levels of Coenzyme Q10 than a single dose of 200 mg. Supplementation was associated with decreased oxidative stress as measured by MDA-levels. Indians appear to have low baseline serum coenzyme Coenzyme Q10 levels which may be due to vegetarian diets. Further studies in larger number of subjects would be necessary to confirm our findings.
Retail sales data for year ending 2007indicate a 19% increase in dollar sales volume and a 9% increase in unit sales of Coenzyme Q10 . The data lists Coenzyme Q10 as the third largest volume non letter vitamin in the vitamin and supplement category behind Glucosamine / Chondroitin and Essential Fatty Acids. It is now estimated there are approximately 6,000,000 U.S. consumers supplementing an average of 82mg Coenzyme Q10 daily.
Sublingual coenzyme Q10
Would dissolving coq10 capsules under the tongue, sublingual, help with its absorption?
We have not seen studies comparing the absorption rate of sublingual coenzyme q10 versus oral forms.
Influence on various blood
Effects of coenzyme Q10 supplementation on plasma adiponectin, interleukin-6, and tumor necrosis factor-alpha levels in men.
J Med Food. 2010.
The aim of the study was to determine the effects of coenzyme Q10 supplementation on plasma adiponectin, interleukin (IL)-6, and tumor necrosis factor (TNF )-alpha levels in sedentary men. Seven participants received oral coenzyme Q10 100 mg/day supplementation, and seven participants received placebo (glucose) for 8 weeks. After a 4-week washout period, placebo was given to the participants who used coenzyme Q10 the first time, and vice versa, and blood sampling was repeated. Plasma was stored at -80 degrees C until the time of analysis for adiponectin, IL-6, and TNF-alpha. Both CoQ10 and placebo supplementation did not affect plasma adiponectin and TNF-alpha levels. IL-6 level increased with coenzyme Q10 supplementation, but this increase did not differ from that seen with placebo supplementation. Coenzyme Q10 supplementation did not affect plasma adiponectin, IL-6, and TNF-alpha levels in sedentary men.

Coenzyme Q10: its biosynthesis and biological significance in animal organisms
and in humans.
Postepy Hig Med Dosw. 2005.
Coenzyme Q10 (ubiquinone) is a naturally occurring compound widely distributed in animal organisms and in humans. The primary compounds involved in the biosynthesis of ubiquinone are 4-hydroxybenzoate and the polyprenyl chain. An essential role of coenzyme Q10 is as an electron carrier in the mitochondrial respiratory chain. Moreover, coenzyme Q10 is one of the most important lipophilic antioxidants, preventing the generation of free radicals as well as oxidative modifications of proteins, lipids, and DNA, it and can also regenerate the other powerful lipophilic antioxidant, alpha-tocopherol. Antioxidant action is a property of the reduced form of coenzyme Q10, ubiquinol (CoQ10H2), and the ubisemiquinone radical (CoQ10H*). Paradoxically, independently of the known antioxidant properties of coenzyme Q10, the ubisemiquinone radical anion (CoQ10-) possesses prooxidative properties. Decreased levels of coenzyme Q10 in humans are observed in many pathologies (e.g. cardiac disorders, neurodegenerative diseases, AIDS, cancer) associated with intensive generation of free radicals and their action on cells and tissues. In these cases, treatment involves pharmaceutical supplementation or increased consumption of coenzyme Q10 with meals as well as treatment with suitable chemical compounds (i.e. folic acid or B-group vitamins) which significantly increase ubiquinone biosynthesis in the organism. Estimation of coenzyme Q10 deficiency and efficiency of its supplementation requires a determination of ubiquinone levels in the organism. Therefore, highly selective and sensitive methods must be applied, such as HPLC with UV or coulometric detection.
Use with Statin drugs for cholesterol
Atorvastatin decreases the Coenzyme Q10 level in the blood of patients at risk for cardiovascular disease and stroke.
Rundek T. olumbia University College of Physicians & Surgeons, New York, NY 10032, USA.
Arch Neurol. 2004.
Statins are widely used for the treatment of hypercholesterolemia and coronary heart disease and for the prevention of stroke. There have been various adverse effects, most commonly affecting muscle and ranging from myalgia to rhabdomyolysis. These adverse effects may be due to a Coenzyme Q10 deficiency because inhibition of cholesterol biosynthesis also inhibits the synthesis of Coenzyme Q10. OBJECTIVE: To measure Coenzyme Q10 levels in blood from hypercholesterolemic subjects before and after exposure to atorvastatin calcium, 80 mg/d, for 14 and 30 days. Prospective blinded study of the effects of short-term exposure to atorvastatin on blood levels of Coenzyme Q10. SETTING: Stroke center at an academic tertiary care hospital. Patients We examined a cohort of 34 subjects eligible for statin treatment according to National Cholesterol Education Program: Adult Treatment Panel III criteria. The mean +/- SD blood concentration of Coenzyme Q10 was 1.26 micro g/mL at baseline, and decreased to 0.62 micro g/mL after 30 days of atorvastatin therapy. A significant decrease was already detectable after 14 days of treatment. Even brief exposure to atorvastatin causes a marked decrease in blood Coenzyme Q10 concentration. Widespread inhibition of Coenzyme Q10 synthesis could explain the most commonly reported adverse effects of statins, especially exercise intolerance, myalgia, and myoglobinuria.

Coenzyme Q10 in patients with end-stage heart failure
awaiting cardiac transplantation: a randomized, placebo-controlled study.
Berman M, Erman A, Ben-Gal T, Heart-Lung Transplant Unit, Rabin Medical Center, Beilinson Campus, Potah Tikva, Israel.
Clin Cardiol. 2004.
The number of patients awaiting heart transplantation is increasing in proportion to the waiting period for a donor. Studies have shown that coenzyme Q10 (CoQ10) has a beneficial effect on patients with heart failure. The purpose of the present double-blind, placebo-controlled, randomized study was to assess the effect of coenzyme Q10 on patients with end-stage heart failure and to determine if coenzyme Q10 can improve the pharmacological bridge to heart transplantation. A prospective double-blind design was used. Thirty-two patients with end-stage heart failure awaiting heart transplantation were randomly allocated to receive either 60 mg U/day of Ultrasome--coenzyme Q10 (special preparation to increase intestinal absorption) or placebo for 3 months. All patients continued their regular medication regimen. Assessments included anamnesis with an extended questionnaire based partially on the Minnesota Living with Heart Failure Questionnaire, 6-min walk test, blood tests for atrial natriuretic factor (ANF) and tumor necrosis factor (TNF), and echocardiography. Twenty-seven patients completed the study. The study group showed significant improvement in the 6-min walk test and a decrease in dyspnea, New York Heart Association (NYHA) classification, nocturia, and fatigue. No significant changes were noted after 3 months of treatment in echocardiography parameters (dimensions and contractility of cardiac chambers) or ANF and TNF blood levels. The administration of coenzyme Q10 to heart transplant candidates led to a significant improvement in functional status, clinical symptoms, and quality of life. However, there were no objective changes in echo measurements or ANF and TNF blood levels. Coenzyme Q10 may serve as an optional addition to the pharmacologic armamentarium of patients with end-stage heart failure. The apparent discrepancy between significant clinical improvement and unchanged cardiac status requires further investigation.
Serum Coenzyme Q10 concentrations in healthy men supplemented with 30 mg or 100 mg coenzyme Q10 for two months in a randomised controlled study.
Zita C. Clinic of Geographic Medicine, Prague, Czech Republic.
Serum coenzyme Q10 concentrations were evaluated in healthy male volunteers supplemented with 30 mg or 100 mg coenzyme Q10 or placebo as a single daily dose for two months in a randomised, double-blind, placebo-controlled study. Median baseline serum coenzyme Q10 concentration in 99 men was 1.26 mg/l. Baseline serum coenzyme Q10 concentration did not depend on age, while borderline significant positive associations were found for body weight and smoking 1-10 cigarettes/d. Supplementation with 30 mg or 100 mg coenzyme Q10 resulted in median increases in serum coenzyme Q10 concentration of 0.55 mg/l and 1.36 mg/l, respectively, compared with a median decrease of 0.23 mg/l with placebo. The changes in the coenzyme Q10 groups were significantly different from that in the placebo group, and the increase in the 100 mg coenzyme Q10 group was significantly greater than that in the 30 mg Q10 group. The change in serum coenzyme Q10 concentration in the Q10 groups did not depend on baseline serum coenzyme Q10 concentration, age, or body weight.

Q. I have been reading through your website. My interest is in the Coenzyme Q10. I believe that it has been helpful in healing my gums as I have been diagnosed with periodontal disease. My gums no longer bleed, and or feel tender to brush which makes for a more effective cleaning. I believe that Coenzyme Q10 is nothing less than miraculous. I found relief at 1 30 mg capsule every 12 hours. This dosage did not affect my ability to sleep. My menstrual periods were long, tedious and painful. I no longer experience that difficulty through my cycle. Thank you for making your info available.
Q. My son William was born in
July, 2001 with Prader-Willi Syndrome. At the age of 3 months William was
still sleeping 20 plus hours a day had no normal wake / sleep pattern when I
found information regarding Prader-Willi Syndrome and the benefits of coenzyme
q10. I immediately ordered coenzyme q10 and began giving William 90 mg daily he
almost immediately responded with a normal wake / sleep pattern. Have you done
any research with coenzyme q10 and Prader-Willi Syndrome? I'm very interested in
any research information you may have.
A. We have not evaluated this condition in relation to coenzyme q10, however we will mention it on our website and maybe others with this condition may try it and give us feedback.
Q. Do you take
yourself? And if
so, how much?
A. I take 30 mg a couple of days a week. I have so many other herbs and supplements on my kitchen counter that I don't want to over do it and take too much along with other supplements that I experiment with.
Q. I just wanted to mention that I recently began taking Coenzyme Q10 and noticed that there was a significant change in my health. I've felt so much better physically and mentally. My ability to focus had been lacking in the past year or so but after taking it I've been able to think clearer. My energy levels are higher, and although I've given up eating beef, I'm noticing a difference in my physical self.
helpful in maintaining healthy gums particularly for
those who are lax in daily flossing. If so, what dosage is recommended.
A. Although a couple of studies have indicated that this supplement may be helpful in gum disease, the most important way to keep healthy gums is to remove the food particles that are stuck between teeth. This is best accomplished by flossing. You may wish to keep your floss by your bed at night or near your favorite sofa while watching TV before bed and thus have a reminder to floss at night. I personally prefer flossing before brushing.
Q. Does the effectiveness matter if it is taken in capsule form or if emulsified in an oil like alpha tocopherol. I read an advertising leaflet that said not to waste money on Coenzyme Q10 tablets or capsules, because they cannot be absorbed into blood stream.
A. There are probably differences in absorption between different CoQ10 products, and perhaps oil emulsified products are better absorbed, however, most Coenzyme Q10 supplements contain 30, 60 or 100 mg which are dosages far greater than normally needed by the body. Hence, even if 100 percent of the CoQ10 is not absorbed, practically speaking it should not make too much difference.

Q. is there anyway you can carry (make) 10mg Coenzyme Q10 ? I'm telling you, the difference between 10mg and even just 30 mg is huge. A ton of benefits on 10mg coenzyme q10, start losing them if I HAVE to take a 30 mg. And the coenzyme q10 doses they are now recommending (100-1,000 mg) are a disaster in the making. I can presently get 10mg CoQ10 from NOW. But I wrote them asking (begging) them not to stop offering the 10mg. Their response? Typical.....they are probably going to discontinue it due to 'all the new research coming out showing HIGH doses are much more effective'. I KNOW this not to be the case for me and I would imagine many many others. Can you start offering a 10mg Coenzyme Q10? And also a 10mg R Lipoic Acid? How about a 1-2 mg DHEA ? :-) Those are the doses I take and they are soooooo good for me. Whereas the higher doses cause me such major problems I just can't/wont take them anymore. Thank you. Love your understanding of low dose supplements.
Q. Read your article about the side effects of Coenzyme q10 . I am a 40
year old female. I have been taking coenzyme q10 30mg for the last one yr.
Recently I upped the dosage to 50mg. After about a week, I started experiencing
insomnia. However I did not relate it the to intake of Coenzyme 10 till I had
already taken the supplement for a month. It has been 10 days since I stopped
taking Coenzyme q10. However my symptons have not gone. I am still experiencing
insomnia and high energy. Do you know how long it can take before the
effects go away completely ?
A. This side effect of coenzyme q10 should go away in a few more days. Take long daily walks to use up the excess energy.
Q. I am a nutritionist and I'm writing to tell you something I've discovered about coenzyme Q10 that I have not been able to find anything about anywhere. For 15 years I suffered from very unpleasant muscle aches that came and went and were strong enough to interrupt my sleep. They seemed to be caused by eating food to which I was allergic. At first it was just fermented food and milk. If I avoided allergens I could avoid these really uncomfortable aches. But as time went on I had them all the time. I tested allergic to all but 4 foods. Then last January I had a brain storm. I knew that if you take statin drugs you can get both muscle pain and depletion of coenzyme Q10. It occurred to me that increasing my dose of coenzyme Q10 might get rid of the muscle pain. So I bumped my dose up from 100 to 300 mg. Amazingly enough the first night I had no muscle pain. When I dropped the dose down to 100 mg, the muscle pain came back. When I upped the dose to 400 I did a little better. The interesting thing is that on 300 or 400 mg of coenzyme Q10 I was able to drink red wine and eat all the food to which I was allergic with no noticeable negative effects. I'm wondering what the mechanism might be. Could the coenzyme Q10 have healed my presumably leaky gut?
There are some other M.D.s, wanting to sell "their"
coenzymeQ10, by saying that many others are synthetic, or are in a powder form
or in capsules, and thus have very limited absorption rates, and offer a gel
based formula instead? What is your opinion on these issues?
There is no need to go fancy or expensive with Coenzyme Q10 supplements. They are all very well absorbed when taken with food. Even if there is a few percentage difference between brands, in practical terms this makes little or no difference. Most people are taking too high doses of Coenzyme q10, anyway so a little less absorption could be a better option. Most people don't need to take more than 30 mg a day and if they are taking a 50 or 100 mg coenzyme q10 capsule or softgel, what difference does it make if there are minor absorption differences?
I read that not only does Coenzyme Q10 improve heart
cells, but it also renovates the highways and byways of all the blood vessels
(e.g., arteries, veins, capillaries). Is that true? If so, what does
"renovation" of the blood vessels mean? In the case of people with high blood
pressure, I also read that taking Coenzyme Q10 can lower blood pressure. Is that
true? By the way, I'm currently taking 400 mg. of Coenzyme Q10 daily.
I am not sure what "renovation" means, it is not a medical term used in describing blood vessels and is not a specific term. The role of coenzyme q10 in blood pressure control is minimal. Coenzyme q10 400 mg is a high dose for most people.
