7 Amazing Benefits of Coenzyme Q10 (COQ10) - How To Take COQ10

Coenzyme Q dosage -

Plasma coenzyme Q 10 concentration one month after angioplasty was positively correlated with less inflammation and oxidative stress and predicted favorable left ventricular end-systolic volume remodeling at six months One randomized controlled trial has examined the effect of coenzyme Q 10 supplementation on periprocedural myocardial injury in patients undergoing coronary angioplasty The administration of mg of coenzyme Q 10 12 hours before the angioplasty to 50 patients reduced the concentration of C-reactive protein [CRP]; a marker of inflammation within 24 hours following the procedure compared to placebo.

However, there was no difference in concentrations of two markers of myocardial injury creatine kinase and troponin-I or in the incidence of major adverse cardiac events one month after angioplasty between active treatment and placebo Additional trials are needed to examine whether coenzyme Q 10 therapy can improve clinical outcomes in patients undergoing coronary angioplasty.

Myocardial ischemia may also lead to chest pain known as angina pectoris. People with angina pectoris often experience symptoms when the demand for oxygen exceeds the capacity of the coronary circulation to deliver it to the heart muscle, e.

In most of the studies, coenzyme Q 10 supplementation improved exercise tolerance and reduced or delayed electrocardiographic changes associated with myocardial ischemia compared to placebo.

However, only two of the studies found significant decreases in symptom frequency and use of nitroglycerin with coenzyme Q 10 supplementation.

Presently, there is only limited evidence suggesting that coenzyme Q 10 supplementation would be a useful adjunct to conventional angina therapy. Very few high-quality trials have examined the potential therapeutic benefit of coenzyme Q 10 supplementation in the treatment of primary hypertension In contrast, a meta-analysis that used less stringent selection criteria included 17 small trials and found evidence of a blood pressure-lowering effect of coenzyme Q 10 in patients with cardiovascular disease or metabolic disorders The effect of coenzyme Q 10 on blood pressure needs to be examined in large, well-designed clinical trials.

Endothelial dysfunction: Normally functioning vascular endothelium promotes blood vessel relaxation vasodilation when needed for example, during exercise and inhibits the formation of blood clots. Atherosclerosis is associated with impairment of vascular endothelial function, thereby compromising vasodilation and normal blood flow.

Endothelium-dependent vasodilation is impaired in individuals with elevated serum cholesterol concentrations, as well as in patients with coronary heart disease or diabetes mellitus.

Evidence from larger studies is needed to further establish the effect of coenzyme Q 10 on endothelium-dependent vasodilation. Recently published pooled analyses of these trials have given mixed results Larger studies are needed to examine the effect of coenzyme Q 10 supplementation on low-grade inflammation.

Blood lipids : Elevated plasma lipoprotein a concentration is an independent risk factor for cardiovascular disease. Other effects of coenzyme Q 10 on blood lipids have not been reported 51, 53, A therapeutic approach combining coenzyme Q 10 with other antioxidants might prove to be more effective to target co-existing metabolic disorders in individuals at risk for cardiovascular disease Diabetes mellitus is a condition of increased oxidative stress and impaired energy metabolism.

Plasma concentrations of reduced coenzyme Q 10 CoQ 10 H 2 have been found to be lower in diabetic patients than healthy controls after normalization to plasma cholesterol concentrations 56, Randomized controlled trials that examined the effect of coenzyme Q 10 supplementation found little evidence of benefits on glycemic control in patients with diabetes mellitus.

Maternally inherited diabetes mellitus-deafness syndrome MIDD is caused by a mutation in mitochondrial DNA , which is inherited exclusively from one's mother.

Of note, the pathogenesis of type 2 diabetes mellitus involves the early onset of glucose intolerance and hyperinsulinemia associated with the progressive loss of tissue responsiveness to insulin.

Recent experimental studies tied insulin resistance to a decrease in coenzyme Q 10 expression and showed that supplementation with coenzyme Q 10 could restore insulin sensitivity 7. Coenzyme Q 10 supplementation might thus be a more useful tool for the primary prevention of type 2 diabetes rather than for its management.

Parkinson's disease is a degenerative neurological disorder characterized by tremors, muscular rigidity, and slow movements.

Mitochondrial dysfunction and oxidative damage in a part of the brain called the substantia nigra may play a role in the development of the disease Decreased ratios of reduced -to- oxidized coenzyme Q 10 have been found in platelets of individuals with Parkinson's disease 61, Two recent meta-analyses of randomized, placebo-controlled trials found no evidence that coenzyme Q 10 improved motor-related symptoms or delayed the progression of the disease when compared to placebo 68, Huntington's disease is an inherited neurodegenerative disorder characterized by selective degeneration of nerve cells known as striatal spiny neurons.

Symptoms, such as movement disorders and impaired cognitive function, typically develop in the fourth decade of life and progressively deteriorate over time. Animal models indicate that impaired mitochondrial function and glutamate -mediated neurotoxicity may be involved in the pathology of Huntington's disease.

Interestingly, co-administration of coenzyme Q 10 with remacemide an NMDA receptor antagonist , the antibiotic minocycline, or creatine led to greater improvements in most biochemical and behavioral parameters To date, only two clinical trials have examined whether coenzyme Q 10 might be efficacious in human patients with Huntington's disease.

All dosages were generally well tolerated, with gastrointestinal symptoms being the most frequently reported adverse effect. Blood concentrations of coenzyme Q 10 at the end of the study were maximized with the daily dose of 2, mg The trial was prematurely halted because it appeared unlikely to demonstrate any health benefit in supplemented patients — about one-third of participants completed the trial at the time of study termination Although coenzyme Q 10 is generally well tolerated, there is no evidence that supplementation can improve functional and cognitive symptoms in Huntington's disease patients.

Friedreich's ataxia FRDA : FRDA is an autosomal recessive neurodegenerative disease caused by mutations in the gene FXN that encodes for the mitochondrial protein , frataxin. Frataxin is needed for the making of iron -sulfur clusters ISC.

ISC-containing subunits are especially important for the mitochondrial respiratory chain and for the synthesis of heme -containing proteins Frataxin deficiency is associated with imbalances in iron-sulfur containing proteins, mitochondrial respiratory chain dysfunction and lower ATP production, and accumulation of iron in the mitochondria, which increases oxidative stress and oxidative damage to macromolecules of the respiratory chain Clinically, FRDA is a progressive disease characterized by ataxia , areflexia , speech disturbance dysarthria , sensory loss, motor dysfunction, cardiomyopathy , diabetes , and scoliosis Follow-up assessments at 47 months indicated that cardiac and skeletal muscle improvements were maintained and that FRDA patients showed significant increases in fractional shortening, a measure of cardiac function.

Moreover, the therapy was effective at preventing the progressive decline of neurological function Large-scale, randomized controlled trials are necessary to determine whether coenzyme Q 10 , in conjunction with vitamin E, has therapeutic benefit in FRDA.

At present, about one-half of patients use coenzyme Q 10 and vitamin E supplements despite the lack of proven therapeutic benefit Spinocerebellar ataxias SCAs : SCAs are a group of rare autosomal dominant neurodegenerative diseases characterized by gait difficulty, loss of hand dexterity, dysarthria, and cognitive decline.

SCA1, 2, 3, and 6 are the most common SCAs In vitro coenzyme Q 10 treatment of forearm skin fibroblasts isolated from patients with SCA2 was found to reduce oxidative stress and normalize complex I and II-III activity of the mitochondrial respiratory chain Early interest in coenzyme Q 10 as a potential therapeutic agent in cancer was stimulated by an observational study that found that individuals with lung, pancreas , and especially breast cancer were more likely to have low plasma coenzyme Q 10 concentrations than healthy controls Two randomized controlled trials have explored the effect of coenzyme Q 10 as an adjunct to conventional therapy for breast cancer.

Supplementation with coenzyme Q 10 failed to improve measures of fatigue and quality of life in patients newly diagnosed with breast cancer 84 and in patients receiving chemotherapy There is little evidence that supplementation with coenzyme Q 10 improves athletic performance in healthy individuals.

Most did not find significant differences between the group taking coenzyme Q 10 and the group taking placebo with respect to measures of aerobic exercise performance, such as maximal oxygen consumption VO 2 max and exercise time to exhaustion Two studies actually found significantly greater improvement in measures of anaerobic 87 and aerobic 86 exercise performance with a placebo than with supplemental coenzyme Q More recent studies have suggested that coenzyme Q 10 could help reduce both muscle damage-associated oxidative stress and low-grade inflammation induced by strenuous exercise Studies on the effect of supplementation on physical performance in women are lacking, but there is little reason to suspect a gender difference in the response to coenzyme Q 10 supplementation.

Coenzyme Q 10 is synthesized in most human tissues. The biosynthesis of coenzyme Q 10 involves three major steps: 1 synthesis of the benzoquinone structure from 4-hydroxybenzoate derived from either tyrosine or phenylalanine, two amino acids; 2 synthesis of the polyisoprenoid side chain from acetyl-coenzyme A CoA via the mevalonate pathway; and 3 the joining condensation of these two structures to form coenzyme Q In the mevalonate pathway, the enzyme 3-hydroxymethylglutaryl HMG -CoA reductase, which converts HMG-CoA into mevalonate, is common to the biosynthetic pathways of both coenzyme Q 10 and cholesterol and is inhibited by statins cholesterol-lowering drugs; see Drug interactions 1.

Of note, pantothenic acid formerly vitamin B 5 is the precursor of coenzyme A, and pyridoxine vitamin B 6 , in the form of pyridoxal-5'-phosphate, is required for the conversion of tyrosine to 4-hydroxyphenylpyruvic acid that constitutes the first step in the biosynthesis of the benzoquinone structure of coenzyme Q The extent to which dietary consumption contributes to tissue coenzyme Q 10 concentrations is not clear.

Rich sources of dietary coenzyme Q 10 include mainly meat, poultry, and fish. Other good sources include soybean, corn, olive, and canola oils; nuts; and seeds. Fruit, vegetables, eggs, and dairy products are moderate sources of coenzyme Q 10 Some dietary sources are listed in Table 1.

Coenzyme Q 10 is available without a prescription as a dietary supplement in the US. Coenzyme Q 10 is fat-soluble and is best absorbed with fat in a meal. Oral supplementation with coenzyme Q 10 is known to increase blood and lipoprotein concentrations of coenzyme Q 10 in humans 2 , 15 , Nonetheless, under certain physiological circumstances e.

During pregnancy, the use of coenzyme Q 10 supplements mg twice daily from 20 weeks' gestation was found to be safe Because reliable data in lactating women are not available, supplementation should be avoided during breast-feeding Concomitant use of warfarin Coumadin and coenzyme Q 10 supplements has been reported to decrease the anticoagulant effect of warfarin in a few cases An individual on warfarin should not begin taking coenzyme Q 10 supplements without consulting the health care provider who is managing his or her anticoagulant therapy.

HMG-CoA reductase is an enzyme that catalyzes a biochemical reaction that is common to both cholesterol and coenzyme Q 10 biosynthetic pathways see Biosynthesis. Statins are HMG-CoA reductase inhibitors that are widely used as cholesterol-lowering medications.

Statins can thus also reduce the endogenous synthesis of coenzyme Q Therapeutic use of statins, including simvastatin Zocor , pravastatin Pravachol , lovastatin Mevacor, Altocor, Altoprev , rosuvastatin Crestor , and atorvastatin Lipitor , has been shown to decrease circulating coenzyme Q 10 concentrations However, because coenzyme Q 10 circulates with lipoproteins , plasma coenzyme Q 10 concentration is influenced by the concentration of circulating lipids , It is likely that circulating coenzyme Q 10 concentrations are decreased because statins reduce circulating lipids rather than because they inhibit coenzyme Q 10 synthesis In addition, very few studies have examined coenzyme Q 10 concentrations in tissues other than blood such that the extent to which statin therapy affects coenzyme Q 10 concentrations in the body's tissues is unknown , , Finally, there is currently little evidence to suggest that secondary coenzyme Q 10 deficiency is responsible for statin-associated muscle symptoms in treated patients.

In addition, supplementation with coenzyme Q 10 failed to relieve myalgia in statin-treated patients see Disease Treatment , Originally written in by: Jane Higdon, Ph.

Malanga Health Benefits and More. Medically reviewed by Natalie Olsen, R. The participants who took the CoQ10 supplements had significantly reduced statin-related muscle pain. Those who received the placebo reported no change in muscle pain. However, the authors of a meta-analysis evaluated the efficacy of CoQ10 supplementation for treating statin-related muscle pain.

The meta-analysis included six studies with a combined total of patients. The authors found no evidence that CoQ10 significantly improves statin-related muscle pain.

Further large-scale RCTs are necessary to determine whether CoQ10 is a viable treatment for people experiencing statin-related muscle pain.

Chronic migraines may be due to inflammation of neurons and cells in a part of the brain called the trigeminovascular system. A clinical trial investigated whether coQ10 supplements could reduce inflammation in 45 women with episodic migraines. The women took mg daily doses of either a CoQ10 supplement or a placebo.

The women who took the CoQ10 supplements had fewer and less intense migraines when compared to the placebo group. Women who took the CoQ10 supplements also showed lower levels of certain inflammatory biomarkers.

Inflammatory biomarkers are substances in the blood that indicate the presence of inflammation somewhere in the body. A meta-analysis reexamined five studies investigating the use of CoQ10 supplements for migraines.

The meta-analysis concluded that CoQ10 is more effective than a placebo at reducing the duration of migraines. However, CoQ10 did not appear to affect migraine severity or frequency. These diseases are associated with free radical damage. A study investigated the effect of a Mediterranean diet combined with CoQ10 supplementation on metabolism in elderly adults.

This combination led to an increase in antioxidant biomarkers in the urine. The authors concluded that taking CoQ10 and eating a diet low in saturated fat may help protect against diseases caused by free radical damage. In another study , older adults received CoQ10 and selenium supplements for 48 months.

The participants reported improvements in vitality, physical performance, and overall quality of life. CoQ10 supplements appear to be safe, and most people tolerate them even at high doses.

However, CoQ10 supplements can cause the following side effects:. People should consult a doctor before taking any new medications or dietary supplements, including CoQ CoQ10 is an antioxidant that exists in almost every cell of the human body. Although the body naturally produces CoQ10, some people may benefit from taking supplements.

Overall, CoQ10 supplements appear relatively safe and cause few side effects. Supplements are not regulated by the Food and Drug Administration FDA for purity or verified for labeling accuracy, so purchase only those products that have been tested by an independent lab. People who are interested in trying CoQ10 supplements may want to consult a healthcare professional first.

Experts do not recommend CoQ10 for people taking blood-thinning medications, insulin , or certain chemotherapy drugs. CoQ10 is available in some drug stores, pharmacies, and online.
