Coenzyme Q levels -

The coenzyme Q10 test is primarily used to diagnose of coenzyme Q10 deficiency in mitochondrial disorders. Coenzyme Q 10 deficiency may occur in three ways: primary coenzyme Q10 deficiency, secondary coenzyme Q10 deficiency, or related to another drug or disease. Primary coenzyme Q10 deficiency is rare and caused by genetic disorder that affects the CoQ10 molecule.

Secondary coenzyme Q 10 deficiency, on the other hand, is caused by a problem in the mitochondria. Mitochondrial diseases cause a variety of symptoms but most are related to muscle weakness and neurological symptoms.

This can lead to breathing problems, heart muscle problems, seizures, and cognitive problems. These treatment considerations are for educational purposes only. Specific treatment plans should be provided and reviewed by the treating practitioner. Dietary sources of CoQ10 include animal products such as beef, pork or chicken, and vegetables such as spinach, cauliflower and broccoli.

If currently taking, consider adjusting dosage and retest in months. If low, consider treatment with niacin or fenofibrate therapy. Understand and improve your laboratory results with our health dashboard.

Our technology helps to understand, combine, track, organize, and act on your medical lab test results. Abnormally high levels of coenzyme Q10 are only practically possible through the use of supplements.

It is unclear whether moderately excessive amounts of coenzyme Q10 are harmful to humans. While it is fat soluble, CoQ10 does not accumulate after supplementation has stopped.

Degree Programs. Research Faculty. 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. Linus Pauling Institute Oregon State University. Updated in February by: Victoria J.

Coenzyme Q levels -

The diagnosis of secondary CoQ10 deficiency can be established by identification of biallelic pathogenic variants in genes that cause mitochondrial diseases, oxidative phosphorylation diseases, or other diseases that lead to CoQ10 deficiency.

Although measurement of CoQ10 in plasma is not useful for diagnosis because it is influenced by dietary sources of CoQ10, this testing can be used to monitor the progress of CoQ10 replacement therapy.

Clinical phenotypes caused by mutations in CoQ synthome and the effect of CoQ 10 therapy in humans. Abnormally low CoQ 10 levels can be associated with mitochondrial pathologies caused by mutations in genes encoding components of the oxidative phosphorylation chain or of other cellular functions not directly associated with mitochondrial function Yubero et al.

Known as secondary CoQ 10 deficiencies, these disorders could represent an adaptive mechanism to bioenergetic requirements. For example, secondary CoQ 10 deficiency can appear in some patients with defects in glucose transport caused by GLUT1 mutations Yubero et al.

A group of patients with very severe neuropathies showed impaired CoQ 10 synthesis, indicating the importance of CoQ 10 homeostasis in human health Asencio et al.

In individuals with primary CoQ 10 deficiency, early treatment with high-dose oral CoQ 10 supplementation improves the pathological phenotype, limits the progression of encephalopathy, and helps recover kidney damage Montini et al.

Onset of renal symptoms in PDSS2 -deficient mice can be prevented with CoQ 10 supplementation Saiki et al. However, patients suffering from secondary CoQ 10 deficiency may fail to respond to CoQ 10 supplementation Pineda et al. A significant reduction in the rate of CoQ biosynthesis has been proposed to occur during the aging process and aging-associated diseases Beyer et al.

However, there are discrepancies about the relationship between the levels of CoQ and the progression of aging. However, other in vivo studies have reported a direct association between longevity and mitochondrial levels of CoQ in the Samp1 model of senescence-accelerated mice Tian et al.

Supplementation with ubiquinol has been shown to activate mechanisms controlling mitochondrial biogenesis Schmelzer et al. The concentrations of CoQ 10 in the plasma of elderly people are positively correlated with levels of physical activity and cholesterol concentrations Del Pozo-Cruz et al.

Older individuals given a combination of selenium and CoQ 10 over a 4-year period reported an improvement in vitality, physical performance, and quality of life Johansson et al.

Furthermore, CoQ 10 supplementation confers health benefits in elderly people by preventing chronic oxidative stress associated with cardiovascular and neurodegenerative diseases Gonzalez-Guardia et al. Despite these evidences, more reliable clinical trials focusing on the elderly are needed before considering CoQ 10 as an effective anti-aging therapy Varela-Lopez et al.

CoQ 10 has been used in the treatment of a number of human pathologies and disorders. Clinical trials, systematic reviews, and meta-analyses have examined the safety and efficacy of CoQ 10 in treating human diseases. As indicated below, prudence is needed when interpreting the results of several clinical trials.

A combination of factors including the small number of trials, substantial differences that exist in the experimental designs, dose and duration of treatment, the number of patients enrolled, and the relative short follow-up periods contribute to apparent inconsistencies in the published data.

Despite these limitations, CoQ 10 can be considered as an important coadjuvant in the treatment of different diseases, especially in chronic conditions affecting the elderly.

The number of deaths attributed to heart failure is increasing worldwide and has become a global health issue. Heart failure is accompanied by increased ROS formation, which can be attenuated with antioxidants. A systematic review has recently examined the efficacy of CoQ 10 supplementation in the prevention of cardiovascular disease CVD without lifestyle intervention Flowers et al.

These authors interpreted the results to indicate a significant reduction in systolic blood pressure without improvements in other CVD risk factors, such as diastolic blood pressure, total cholesterol, LDL- and high-density lipoprotein HDL -cholesterol, and triglycerides. A second meta-analysis explored the impact of CoQ 10 in the prevention of complications in patients undergoing cardiac surgery, and the results showed that CoQ 10 therapy lowers the need of inotropic drugs and reduces the appearance of ventricular arrhythmias after surgery de Frutos et al.

Short-term daily treatment 12 weeks or less with mg CoQ 10 improves left ventricular ejection fraction in patients suffering from heart failure Fotino et al. In contrast, no effect of CoQ 10 was observed on left ventricular ejection fraction or exercise capacity in patients with heart failure Madmani et al.

CoQ 10 has been proposed for the treatment of metabolic syndrome and type 2 diabetes by virtue of its antioxidant properties. However, analysis of more than seven trials involving participants showed that CoQ 10 supplementation for at least 12 weeks had no significant effects on glycemic control, lipid profile, or blood pressure in diabetic patients, but was able to reduce serum triglycerides levels Suksomboon et al.

In a follow-up analysis of data obtained from Q-SYMBIO clinical trials Mortensen et al. Supplementation with CoQ 10 has produced beneficial effects in the treatment of hypercholesterolemia and hypertriglyceridemia by initiating changes in blood lipid concentration.

A combination of CoQ 10 with red yeast rice, berberina, policosanol, astaxanthin, and folic acid significantly decreased total cholesterol, LDL-cholesterol, triglycerides, and glucose in the blood while increasing HDL-cholesterol levels Pirro et al.

However, the impact of CoQ 10 alone without the other supplements was not directly assessed. Nevertheless, there are reports to suggest that CoQ 10 is very effective in reducing serum triglycerides levels Suksomboon et al. Chronic treatment with statins is associated with myopathy Law and Rudnicka, , a side-effect representing a broad clinical spectrum of disorders largely associated with a decrease in CoQ 10 levels and selenoprotein activity Thompson et al.

Statins impair skeletal muscle and myocardial bioenergetics Littarru and Langsjoen, via inhibition of 3-hydroxymethylglutaryl-CoA HMG-CoA reductase, a key enzyme in the mevalonate pathway implicated in cholesterol and CoQ biosynthesis, and reduction in mitochondrial complex III activity of the electron transport chain Schirris et al.

A total of 60 patients suffering from statin-associated myopathy were enrolled in a 3-month study to test for efficacy of CoQ 10 and selenium treatment. A consistent reduction in their symptoms, including muscle pain, weakness, cramps, and fatigue was observed, suggesting an attenuation of the side-effects of chronic statin treatment following CoQ 10 supplementation Fedacko et al.

In a previous study, however, 44 patients suffering from statin-induced myalgia saw no improvement in their conditions after receiving CoQ 10 for 3 months Young et al.

Other studies have determined that CoQ 10 supplementation improves endothelial dysfunction in type 2 diabetic patients treated with statins Hamilton et al. Oxidative stress plays an essential role in diabetic kidney disease, and experiments performed on rats showed a promising protective effect of ubiquinol in the kidneys Ishikawa et al.

However, a meta-analysis study examining the efficiency of antioxidants on the initiation and progression of diabetic kidney disease revealed that antioxidants, including CoQ 10 , did not have reliable effects against this disease Bolignano et al. Chronic inflammation and oxidative stress are associated with many age-related diseases such as cardiovascular diseases, diabetes, cancer, and chronic kidney disease.

A recent meta-analysis explored the efficacy of CoQ 10 on the plasma levels of C-reactive protein, interleukin 6 IL-6 and tumor necrosis factor alpha TNF-α in patients afflicted with pathologies in which inflammation was a common factor including cardio-cerebral vascular disease, multiple sclerosis, obesity, renal failure, rheumatoid arthritis, diabetes, and fatty liver disease Fan et al.

The authors also surmised that CoQ 10 supplementation decreased pro-inflammatory cytokines and inflammatory markers in the elderly with low CoQ 10 levels Fan et al. Metabolic diseases, characterized by chronic, low grade inflammation, respond well to CoQ 10 supplementation with significant decrease in TNF-α plasma levels without having an effect on C-reactive protein and IL-6 production Zhai et al.

More recently, CoQ 10 has been found to markedly attenuate the elevated expression of inflammatory and thrombotic risk markers in monocytes of patients with antiphospholipid syndrome, thereby improving endothelial function and mitochondrial activity in these patients Perez-Sanchez et al.

A proinflammatory profile has also been associated with the progression of neurological symptoms in Down syndrome patients Wilcock and Griffin, These patients have low CoQ 10 plasma levels together with high plasma levels of proinflammatory cytokines, such as IL-6 and TNF-α Zaki et al.

Supplementation with CoQ 10 confers protection against the progression of oxidative damage and mitochondrial dysfunction in Down syndrome patients Tiano and Busciglio, ; Tiano et al.

Preclinical studies demonstrated that CoQ can preserve mitochondrial function and reduce the loss of dopaminergic neurons in the case of Parkinson's disease Schulz and Beal, Experimental studies in animal models suggest that CoQ 10 may protect against neuronal damage caused by ischemia, atherosclerosis, and toxic injury Ishrat et al.

Further, a screening for oxidative stress markers in patients with Parkinson's disease reported lower levels of CoQ 10 and α-tocopherol and higher levels of lipoprotein oxidation in the plasma and cerebrospinal fluid compared to non-affected individuals Buhmann et al.

Moreover, CoQ 10 deficiency was observed at a higher frequency in Parkinson's disease, underscoring its utility as a peripheral biomarker Mischley et al. For this reason, it has been suggested that CoQ 10 supplementation could benefit patients suffering from neurodegenerative diseases.

Two reviews on recent clinical trials testing CoQ 10 supplementation reported the lack of improvement in motor functions in patients with neurodegenerative diseases, which led the authors to conclude that the use of CoQ 10 in these patients is unnecessary Liu and Wang, ; Negida et al.

However, other clinical trials in patients suffering from Parkinson's, Huntington's, and Friedreich's ataxia suggest that CoQ 10 supplementation could delay functional decline, particularly with regard to Parkinson's disease Beal, ; Shults, Indeed, four randomized, double-blind, placebo-controlled studies comparing CoQ 10 treatment in patients at early or mid-stage Parkinson's disease reported improvements in daily activities and other parameters Liu et al.

In contrast, a more recent multicenter randomized, double-blind, and placebo-controlled trial with CoQ 10 in patients with early-stage Huntington's disease did not slow the rate of patients' functional decline McGarry et al.

There is not enough evidence to indicate that CoQ 10 supplementation can delay the progression of Huntington's disease, at least in its early stages. Initiated in , the Alzheimer's Disease Cooperative Study evaluates the safety, tolerability, and impact of different antioxidants on biomarkers in this disease.

The role of plasma membrane CoQ 10 in autism has been recently proposed Crane et al. Patients with autistic spectrum disorders ASDs exhibit higher proportions of mitochondrial dysfunctions than the general population Rossignol and Frye, , as evidenced by developmental regression, seizures, and elevated serum levels of lactate or pyruvate in ASD patients.

Treatment with carnitine, CoQ 10 , and B-vitamins confers some improvements in ASD patients Rossignol and Frye, ; Gvozdjakova et al. Male infertility has been associated with oxidative stress, and CoQ 10 levels in seminal fluid is considered an important biomarker of healthy sperm Gvozdjakova et al.

Administration of CoQ 10 improves semen parameters in the treatment of idiopathic male infertility Arcaniolo et al. With regard to female infertility, the decrease in mitochondrial activity associated with CoQ 10 deficiency probably affects the granulosa cells' capacity to generate ATP Ben-Meir et al.

Indeed, reduction of CoQ 10 levels in oocyte-specific PDSS2 -deficient mice results in oocyte deficits and infertility Ben-Meir et al. Despite the absence of previous clinical trials that evaluate the effectiveness of CoQ 10 supplementation in female infertility, these studies show promising results of this natural supplement in boosting female fertility during the prime reproductive period.

CoQ 10 deficiency can be associated with a number of human diseases and age-related chronic conditions. In other cases, deficiency in CoQ 10 and its associated antioxidative activity can significantly increase the level of oxidative damage.

It seems clear that supplementation with CoQ 10 improves mitochondrial function and confers antioxidant protection for organs and tissues affected by various pathophysiological conditions. The ability of CoQ 10 to protect against the release of proinflammatory markers provides an attractive anti-inflammatory therapeutic for the treatment of some human diseases and in aging Figure 2.

Figure 2. Effects of CoQ 10 in human diseases. The positive effect of CoQ 10 has been already demonstrated in mitochondrial syndromes associated with CoQ 10 deficiency, inflammation, and cardiovascular diseases as well as in the delay of some age-related processes. Dashed lines depict other positive effects of CoQ 10 with regard to kidney disease, fertility, metabolic syndrome, diabetes, and neurodegenerative diseases.

However, more research is needed to validate these observations. Following intraperitoneal administration of CoQ 10 in rat, only small amount of the supplement reaches the kidney, muscle, and brain.

Likewise, only a fraction of the orally administered CoQ 10 reaches the blood while the major amount is eliminated via feces Bentinger et al. The absoption of CoQ 10 is slow and limited due to its hydrophobicity and large molecular weight and, therefore, high doses are needed to reach a number of rat tissues e.

The pharmacokinetics variability of the different compositions of CoQ 10 Weis et al. Systematic reviews and meta-analyses have revealed that there are few randomized clinical trials on the effect of CoQ 10 in combatting disease progression and improving quality of life.

The results of these trials have been inconsistent likely due to varied dosages, small sample size, and short follow-up periods. More studies performed on humans in focused trials are needed in order to understand the promising effects of CoQ All authors listed have made a substantial, direct and intellectual contribution to the work, and approved it for publication.

In one analysis, after reviewing 12 clinical studies, researchers concluded that CoQ10 has the potential to lower systolic blood pressure by up to 17 mm Hg and diastolic blood pressure by 10 mm Hg, without significant side effects.

More research with greater numbers of people is needed. DO NOT try to treat high blood pressure by yourself. See your provider for treatment. People with high cholesterol tend to have lower levels of CoQ10, so CoQ10 has been proposed as a treatment for high cholesterol, but scientific studies are lacking.

There is some evidence it may reduce side effects from conventional treatment with cholesterol-lowering drugs called statins, which reduce natural levels of CoQ10 in the body. Taking CoQ10 supplements can bring levels back to normal.

Plus, studies show that CoQ10 may reduce the muscle pain associated with statin treatment. Ask your provider if you are interested in taking CoQ10 with statins. CoQ10 supplements may improve heart health and blood sugar and help manage high blood pressure in people with diabetes.

Preliminary studies found that CoQ10 improves blood sugar control. But other studies show no effect. If you have diabetes, talk to your doctor or registered dietitian before taking CoQ Several clinical studies suggest that CoQ10 may help prevent heart damage caused by certain chemotherapy drugs, adriamycin, or other athracycline medications.

More studies are needed. Talk to your provider before taking any herbs or supplements if you are undergoing chemotherapy. Clinical research indicates that introducing CoQ10 prior to heart surgery, including bypass surgery and heart transplantation, can reduce damage caused by free radicals, strengthen heart function, and lower the incidence of irregular heart beat arrhythmias during the recovery phase.

You should not take any supplements before surgery unless your provider approves. Gum disease is a common problem that causes swelling, bleeding, pain, and redness of the gums.

Clinical studies show that people with gum disease tend to have low levels of CoQ10 in their gums. A few studies with small numbers of people found that CoQ10 supplements led to faster healing and tissue repair, but more research is needed.

Scientific studies are needed to see whether CoQ10 can be safely and effectively used for these health problems and needs. Primary dietary sources of CoQ10 include oily fish such as salmon and tuna , organ meats such as liver , and whole grains. Most people get enough CoQ10 through a balanced diet, but supplements may help people with particular health conditions see Uses section , or those taking certain medications see Interactions section.

CoQ10 is available as a supplement in several forms, including soft gel capsules, oral spray, hard shell capsules, and tablets. CoQ10 is also added to various cosmetics. Pediatric DO NOT give CoQ10 to a child under 18 except under the supervision of a health care provider.

For adults 19 years and older: The recommended dose for CoQ10 supplementation is 30 to mg daily. Soft gels tend to be better absorbed than capsules or other preparations. Higher doses may be recommended for specific conditions. CoQ10 is fat soluble, so it should be taken with a meal containing fat so your body can absorb it.

Also, taking CoQ10 at night may help with the body's ability to use it. Because of the potential for side effects and interactions with medications, you should take dietary supplements only under the supervision of a knowledgeable health care provider. CoQ10 appears to be safe with no major side effects, except occasional stomach upset.

However, researchers have not done studies and do not know if CoQ10 supplements are safe during pregnancy and breastfeeding. CoQ10 may lower blood sugar, so people with diabetes should talk with their provider before taking it to avoid the risk of low blood sugar.

Some suggest that it may also lower blood pressure. If you are being treated with any of the following medications, you should not use CoQ10 without first talking to your health care provider.

Chemotherapy medications: Researchers are not sure whether CoQ10's antioxidant effect might make some chemotherapy drugs less effective. Ask your oncologist before taking antioxidants or any supplement along with chemotherapy. Daunorubicin and doxorubicin: CoQ10 may help reduce the toxic effects on the heart caused by daunorubicin Cerubidin and doxorubicin Adriamycin , two chemotherapy medications that are used to treat several kinds of cancer.

Blood pressure medications: CoQ10 may work with blood pressure medications to lower blood pressure. In a clinical study of people taking blood pressure medications, adding CoQ10 supplements allowed them to reduce the doses of these medications.

More research is needed, however. If you take medication for high blood pressure, talk to your provider before taking CoQ10, and DO NOT stop taking your regular medication.

Blood-thinning medications: There have been reports that CoQ10 may make medications such as warfarin Coumadin or clopidigrel Plavix less effective at thinning the blood.

If you take blood thinners, ask your provider before taking CoQ Betaxolol Betoptic : CoQ10 supplements may reduce the heart-related side effects of betaxolol drops Betoptic , a beta-blocker medication used to treat glaucoma, without making the medication any less effective.

Coenzyme Sugar consumption and heart disease CoQ is an essential component of Sugar consumption and heart disease mitochondrial electron transport chain and Coenzyms antioxidant levelz plasma membranes Coebzyme lipoproteins. It Coenzyne endogenously produced in all Plant-based meal planner by a highly regulated Coenyzme that involves a mitochondrial multiprotein complex. Here, we review the current knowledge of CoQ 10 biosynthesis and primary CoQ 10 deficiency syndrome, and have collected published results from clinical trials based on CoQ 10 supplementation. There is evidence that supplementation positively affects mitochondrial deficiency syndrome and the symptoms of aging based mainly on improvements in bioenergetics. Cardiovascular disease and inflammation are alleviated by the antioxidant effect of CoQ Coenzyje Clinic Coenzyme Q levels appointments in Arizona, Florida and Coenzyme Q levels and at Mayo Clinic Health System locations. OCenzyme Q10 CoQ10 is Recovery counseling services antioxidant that levells body produces naturally. Your Recharge with Rewards use CoQ10 for growth and maintenance. Levels of CoQ10 in your body decrease as you age. CoQ10 levels have also been found to be lower in people with certain conditions, such as heart disease, and in those who take cholesterol-lowering drugs called statins. CoQ10 is found in meat, fish and nuts. The amount of CoQ10 found in these dietary sources, however, isn't enough to significantly increase CoQ10 levels in your body.
