The “heart health” sections of most health foods stores are flush with supplements containing coenzyme Q10 (CoQ10), a naturally occurring compound found in small quantities in fish and organ meats. There’s good justification for this strategic product placement. In fact, the most current studies using CoQ10 in patients with cardiovascular disease have turned up very positive findings. In particular, improvements in endothelial function, oxidative status and physical performance in those with coronary artery disease and chronic heart failure have been noted. But, there’s much more to the CoQ10 story than just that. Because this coenzyme possesses antioxidant properties and the ability to support cellular energy, it also has applications in other areas ranging from aging skin to migraine headaches.

This past year has brought about a series of studies that have examined an unlikely pairing of natural therapies: CoQ10 supplementation combined with a Mediterranean diet. The results, discovered by a group of Spanish scientists, have piqued the interest of nutritional experts throughout the world. According to their research, combining a Mediterranean diet with CoQ10 over a 4 week period reduces DNA damage, oxidative stress and proinflammatory gene expression – processes that are all associated with age-related decline. As an interesting side note, a recent publication in the Journal of Agricultural Food Chemistry offers a reminder that extra virgin olive oil, a staple in Mediterranean diets, is a natural source of CoQ10. High dose coenzyme Q10 supplementation has likewise been linked to beneficial effects in the following conditions: Dry Mouth: 100 mg/day was found to improve salivary secretion in patients in a one month investigation. Fibromyalgia: A 9 month trial utilizing 300 mg/day demonstrated significant benefits in a small group of women living with this fatigue-inducing, painful condition. Migraine: The addition of 100 mg/day to conventional treatment resulted in superior short-term relief of headache duration, frequency and severity in adolescents and children.

Even cosmetic manufacturers are jumping onto the CoQ10 bandwagon. Solid lipid nanoparticles, a new technology used in select skin care products, may transform CoQ10 into a potent anti-aging remedy. Reducing the particle size of CoQ10 enhances dermal penetration and may counteract sun damage and wrinkling of the skin. These documented successes and others will hopefully inspire more scientists to delve further into the vast health promoting potential that resides within coenzyme Q10.

    I find the activated form of COQ10, Ubiquinol the only form which works for me. I have more energy and lower blood pressure taking Ubiquinol rather than Ubiquinone. Its more expensive but IMO well worth the extra cost.

  2. JP Says:

    Interesting, Liverock. I’ll do some more in depth research on ubiquinol sometime soon. Thus far, the amount of data (I’ve seen) is limited, but promising. An example:

    The multi I take already contains a rather large amount of ubiquinone. If it didn’t, I’d consider experimenting with ubiquinol myself and report back.

    Be well!

    Coenzyme Q10 as a treatment for fatigue and depression in multiple sclerosis patients: A double blind randomized clinical trial.

    Objectives: Multiple sclerosis (MS) is the chronic inflammatory and demyelinating disorder of central nervous system which is accompanied with disability and negative life style changes such as fatigue and depression. The aim of this study is to investigate the effect of coenzyme Q10 (CoQ10) supplementation on fatigue and depression in patients with MS.

    Methods: We performed a randomized, double-blinded, placebo-controlled trial to determine the effect of CoQ10 supplement (500 mg/day) vs. placebo for 12 weeks. Fatigue symptoms were quantified by means of fatigue severity scale (FSS) and the Beck depression inventory (BDI) was used to assess depressive symptoms.

    Results: A significant decrease of FSS was observed in CoQ10 group during the intervention (P = 0.001) and significant increase of FSS change was observed within placebo group (P = 0.001). Repeated measure analysis of variance showed a significant time-by-treatment interaction for FSS (baseline 41.5 ± 15.6 vs. endpoint 45 ± 13.6; F1,45 = 55.23, P < 0.001, η2 = 0.56) and BDI (baseline 17.8 ± 12.2 vs. endpoint 20.4 ± 11.4; F1,45 = 40.3, P < 0.001, η2 = 0.48), indicating significant decrease of FSS and BDI in CoQ10 group compared to placebo group. Conclusion: Our study suggests that CoQ10 supplementation (500 mg/day) can improve fatigue and depression in patients with multiple sclerosis. Be well! JP

    The Effect of Creatine and Coenzyme Q10 Combination Therapy on Mild Cognitive Impairment in Parkinson’s Disease.

    BACKGROUND: To investigate the effect of creatine and coenzyme Q10 (CoQ10) combination therapy on mild cognitive impairment (MCI) in Parkinson’s disease (PD; PD-MCI) and its influences on plasma phospholipid (PL) levels in PD-MCI.

    METHODS: The demographic data of 75 PD-MCI patients who enrolled in this collaborative PD study were collected. These patients were evaluated using the Unified Parkinson’s Disease Rating Scale (UPDRS) III and the Montreal Cognitive Assessment (MoCA). These 75 PD-MCI patients were randomly treated with creatine monohydrate 5 g b.i.d. and CoQ10 100 mg t.i.d. orally or placebo. MoCA evaluation and PL level measurements were performed after 12 and 18 months of treatment.

    RESULTS: After 12 and 18 months of treatment, the differences in the MoCA scores of the combination therapy and control groups were statistically significant (p < 0.05 at 12 months and p < 0.01 at 18 months), and the plasma PL levels of the combination therapy group were significantly lower than those of the control group (p < 0.01 at 12 months and p < 0.001 at 18 months). CONCLUSIONS: Combination therapy with creatine and CoQ10 could delay the decline of cognitive function in PD-MCI patients and could lower their plasma PL levels; therefore, this combination therapy may have a neuroprotective function.

    Improvement of migraine symptoms with a proprietary supplement containing riboflavin, magnesium and Q10: a randomized, placebo-controlled, double-blind, multicenter trial.

    BACKGROUND: Non-medical, non-pharmacological and pharmacological treatments are recommended for the prevention of migraine. The purpose of this randomized double-blind placebo controlled, multicenter trial was to evaluate the efficacy of a proprietary nutritional supplement containing a fixed combination of magnesium, riboflavin and Q10 as prophylactic treatment for migraine.

    METHODS: 130 adult migraineurs (age 18 – 65 years) with ≥ three migraine attacks per month were randomized into two treatment groups: dietary supplementation or placebo in a double-blind fashion. The treatment period was 3 months following a 4 week baseline period without prophylactic treatment. Patients were assessed before randomization and at the end of the 3-month-treatment-phase for days with migraine, migraine pain, burden of disease (HIT-6) and subjective evaluation of efficacy.

    RESULTS: Migraine days per month declined from 6.2 days during the baseline period to 4.4 days at the end of the treatment with the supplement and from 6.2.days to 5.2 days in the placebo group (p = 0.23 compared to placebo). The intensity of migraine pain was significantly reduced in the supplement group compared to placebo (p = 0.03). The sum score of the HIT-6 questionnaire was reduced by 4.8 points from 61.9 to 57.1 compared to 2 points in the placebo-group (p = 0.01). The evaluation of efficacy by the patient was better in the supplementation group compared to placebo (p = 0.01).

    CONCLUSIONS: Treatment with a proprietary supplement containing magnesium, riboflavin and Q10 (Migravent® in Germany, Dolovent® in USA) had an impact on migraine frequency which showed a trend towards statistical significance. Migraine symptoms and burden of disease, however, were statistically significantly reduced compared to placebo in patients with migraine attacks.

    Parkinsonism Relat Disord. 2015 May 29.

    Randomized, double-blind, placebo-controlled pilot trial of reduced coenzyme Q10 for Parkinson’s disease.

    INTRODUCTION: Mitochondrial complex I deficiencies have been found in post-mortem brains of patients with Parkinson’s disease (PD). Coenzyme Q10 (CoQ10) is the electron acceptor found in complexes I and II, and is a potent antioxidant. A recent trial of the oxidized form of CoQ10 for PD failed to show benefits; however, the reduced form of CoQ10 (ubiquinol-10) has shown better neuroprotective effects in animal models.

    METHODS: Randomized, double-blind, placebo-controlled, parallel-group pilot trials were conducted to assess the efficacy of ubiquinol-10 in Japanese patients with PD. Participants were divided into two groups: PD experiencing wearing off (Group A), and early PD, without levodopa (with or without a dopamine agonist) (Group B). Participants took 300 mg of ubiquinol-10 or placebo per day for 48 weeks (Group A) or 96 weeks (Group B).

    RESULTS: In Group A, total Unified Parkinson’s Disease Rating Scale (UPDRS) scores decreased in the ubiquinol-10 group (n = 14; mean ± SD [-4.2 ± 8.2]), indicating improvement in symptoms. There was a statistically significant difference (p < 0.05) compared with the placebo group (n = 12; 2.9 ± 8.9). In Group B, UPDRS increased in the ubiquinol-10 group (n = 14; 3.9 ± 8.0), as well as in the placebo group (n = 8; 5.1 ± 10.3). CONCLUSIONS: This is the first report showing that ubiquinol-10 may significantly improve PD with wearing off, as judged by total UPDRS scores, and that ubiquinol-10 is safe and well tolerated.

    The effects of coenzyme Q10 administration on glucose homeostasis parameters, lipid profiles, biomarkers of inflammation and oxidative stress in patients with metabolic syndrome.

    BACKGROUND: Limited data are available indicating the effects of coenzyme Q10 (CoQ10) supplementation on metabolic status of patients with metabolic syndrome (MetS).

    PURPOSE: The present study was conducted to determine the effects of CoQ10 administration on glucose homeostasis parameters, lipid profiles, biomarkers of inflammation and oxidative stress among patients with MetS.

    METHODS: This randomized, double-blind, placebo-controlled trial was performed among 60 overweight or obese and type 2 diabetes mellitus patients with coronary heart disease aged 40-85 years old. Participants were randomly allocated into two groups. Group A (n = 30) received 100 mg CoQ10 supplements and group B (n = 30) received placebo for 8 weeks. Fasting blood samples were taken at the beginning of the study and after 8-week intervention to quantify glucose homeostasis parameters, lipid profiles and biomarkers of inflammation and oxidative stress.

    RESULTS: Compared with the placebo, CoQ10 supplementation resulted in a significant reduction in serum insulin levels (-2.1 ± 7.1 vs. +4.1 ± 7.8 µIU/mL, P = 0.002) and homeostasis model of assessment-insulin resistance (-0.7 ± 2.1 vs. +1.0 ± 2.0, P = 0.002) and homeostatic model assessment-beta cell function (-5.9 ± 22.2 vs. +15.9 ± 34.0, P = 0.005). In addition, patients who received CoQ10 supplements had a significant increase in plasma total antioxidant capacity (TAC) concentrations (+26.0 ± 105.0 vs. -162.2 ± 361.8 mmol/L, P = 0.008) compared with the placebo group. However, after adjustment for the baseline levels, age and baseline BMI, the effect on TAC levels (P = 0.08) disappeared. Additionally, compared with the placebo group, a significant positive trends in plasma glutathione (P = 0.06) and a significant reduction in malondialdehyde (P = 0.08) were seen among patients who received CoQ10 supplement. We did not observe any significant changes in fasting plasma glucose, lipid concentrations and inflammatory markers.

    CONCLUSIONS: Overall, daily intake of 100 mg CoQ10 supplements among patients with MetS for 8 weeks had beneficial effects on serum insulin levels, HOMA-IR, HOMA-B and plasma TAC concentrations.

    Effects of coenzyme Q10 supplementation on C-reactive protein and homocysteine as the inflammatory markers in hemodialysis patients; a randomized clinical trial.

    BACKGROUND: The most leading cause of death in end-stage renal disease (ESRD) patients are cardiovascular disease and inflammatory markers are related to coronary events. CO-Q10 (coenzyme Q10) is a protective supplement from free radical oxidative damage. In addition, hyperhomocysteinemia is an independent coronary artery disease (CAD) risk factor.

    OBJECTIVES: Due to increasing oxidative stress in dialysis patients, and the effect of CO-Q10 in decrease oxidative stress, in this work, we assessed the effect of CO-Q10 on C-reactive protein (CRP) level as an inflammatory marker and homocysteine in dialysis patients.

    PATIENTS AND METHODS: This was a single-blind, randomized cross over clinical trial. Patients with ESRD were randomly allotted to two groups. All patients received placebo and C0- Q10 100mg/d during the three months in each stage, with two week washout period. Plasma level of CRP and homocysteine from the start of the work and at the conclusion of each menses, are evaluated.

    RESULTS: Thirty-four patients randomized, but 26 patients complete study protocol. The treatment effect of CO-Q10 on CRP level is significant (P < 0.001) (95% CI = -20.1 to -10.5) and it was also significant for the increasing albumin level. (P = 0.044) (95% CI = 0. 0-0.6), But there was not any substantial effect on serum homocysteine level (P = 0.630). CONCLUSIONS: CO-Q10 could significantly decrease CRP level as an inflammatory marker and can protect cardiovascular events. Be well! JP

    Combination therapy with coenzyme Q10 and trimetazidine in acute viral myocarditis patients.

    BACKGROUND: Acute viral myocarditis is an inflammatory disease with global impact. Although it may resolve spontaneously, its course is not easily predicted and there is a paucity of specific treatment options available with proven efficacy. Coenzyme Q10 (CQ10) and trimetazidine possess antioxidant and anti-inflammatory effects.

    METHODS: We examined the therapeutic efficacy of these agents in acute viral myocarditis both individually and in combination. Patients were blinded and randomised to receive CQ10 (n=42), trimetazidine (n=39), or CQ10 + trimetazidine (n=43) treatment.

    RESULTS: Serum inflammatory and oxidative stress marker and myocardial enzyme levels, and heart function were measured. Both CQ10 and trimetazidine decreased inflammatory and oxidative stress biomarker levels compared to baseline measurements. However, combination therapy with CQ10 and trimetazidine showed a significantly more powerful effect not only on markers of inflammation and oxidative stress, but also on left ventricular systolic function and troponin, compared to either treatment alone.

    CONCLUSION: This study confirmed the beneficial effect of CQ10 and trimetazidine individually, but demonstrated a superior effect of combining the therapies on cardiac left ventricular ejection fraction, and biochemical markers of myocardial damage in acute viral myocarditis.

    Coenzyme Q10 and Heart Failure: A State-of-the-Art Review.

    Heart failure (HF) with either preserved or reduced ejection fraction is associated with increased morbidity and mortality. Evidence-based therapies are often limited by tolerability, hypotension, electrolyte disturbances, and renal dysfunction. Coenzyme Q10 (CoQ10) may represent a safe therapeutic option for patients with HF. CoQ10 is a highly lipophilic molecule with a chemical structure similar to vitamin K. Although being a common component of cellular membranes, CoQ10’s most prominent role is to facilitate the production of adenosine triphosphate in the mitochondria by participating in redox reactions within the electron transport chain. Numerous trials during the past 30 years examining CoQ10 in patients with HF have been limited by small numbers and lack of contemporary HF therapies. The recent publication of the Q-SYMBIO randomized controlled trial demonstrated a reduction in major adverse cardiovascular events with CoQ10 supplementation in a contemporary HF population. Although having limitations, this study has renewed interest in evaluating CoQ10 supplementation in patients with HF. Current literature suggests that CoQ10 is relatively safe with few drug interactions and side effects. Furthermore, it is already widely available as an over-the-counter supplement. These findings warrant future adequately powered randomized controlled trials of CoQ10 supplementation in patients with HF. This state-of-the-art review summarizes the literature about the mechanisms, clinical data, and safety profile of CoQ10 supplementation in patients with HF.

    Short-term ubiquinol supplementation reduces oxidative stress associated with strenuous exercise in healthy adults: A randomized trial.

    Studies about Coenzyme Q10 (CoQ10 ) supplementation on strenuous exercise are scarce, especially those related with oxidative stress associated with physical activity and virtually nonexistent with the reduced form, Ubiquinol. The objective of this study was to determine, for the first time, whether a short-term supplementation with Ubiquinol can prevent oxidative stress associated to strenuous exercise. The participants (n = 100 healthy and well trained, but not on an elite level) were classified in two groups: Ubiquinol (experimental group), and placebo group (control). The protocol consisted of conducting two identical strenuous exercise tests with a rest period between tests of 24 h. Blood and urine samples were collected from the participants before supplementation (basal value) (T1), after supplementation (2 weeks) (T2), after first physical exercise test (T3), after 24 h of rest (T4), and after second physical exercise test (T5).The increase observed in the lactate, isoprostanes, DNA damage, and hydroperoxide levels reveals the severity of the oxidative damage induced by the exercise. There was a reduction in the isoprostanes, 8-OHdG, oxidized LDL, and hydroperoxydes in the supplemented Ubiquinol group, an increase in total antioxidant status, fat soluble antioxidant (both plasma and membrane), and CAT activity. Also, NO in the Ubiquinol-supplemented group was maintained within a narrow range. Oxidative stress induced by strenuous exercise is accumulative and increases transiently in subsequent sessions of physical activity. A short-term supplementation (2 weeks) with Ubiquinol (200 mg/day) before strenuous exercise, decreases oxidative stress and increases plasma NO, fact that could improve endothelial function, energetic substrate supply, and muscle recovery after strenuous exercise.

    The effect of dietary intake of coenzyme Q10 on skin parameters and condition: Results of a randomised, placebo-controlled, double-blind study.

    Coenzyme Q10 (CoQ10) is a natural constituent of foods and is also often used in both functional foods and supplements. In addition, it is a common ingredient of cosmetics where it is believed to reduce the signs of skin ageing. However, the existing data about the effect of dietary intake of CoQ10 on skin parameters and condition are scarce. To gain an insight into this issue, we conducted a double-blind, placebo-controlled experiment with 33 healthy subjects. Our objective was to investigate the effects of 12 weeks of daily supplementation with 50 and 150 mg of CoQ10 on skin parameters and condition. Study was conducted with a water-soluble form of CoQ10 with superior bioavailability (Q10Vital® ). While the results of some previous in vitro studies showed possible protection in UVB response, we did not observe significant changes in the minimal erythema dose (MED). On the other hand, the intake of CoQ10 limited seasonal deterioration of viscoelasticity and reduced some visible signs of ageing. We determined significantly reduced wrinkles and microrelief lines, and improved skin smoothness. Supplementation with CoQ10 did not significantly affect skin hydration and dermis thickness.

    Effectiveness of coenzyme Q10 in prophylactic treatment of migraine headache: an open-label, add-on, controlled trial.

    Despite the huge health and economic burden of migraine headache, few medications have been approved for its prophylactic treatment, most of which can potentially induce serious adverse effects. Coenzyme Q10 (CoQ10) is a supplement and has shown preliminary benefits in migraine prophylaxis. We aimed to assess this effect in an adult population. This is an open-label, parallel, add-on, match-controlled trial. Eighty patients diagnosed with migraine headache based on International Headache Society criteria were allocated to receiving only their current preventive drugs or their current preventive drugs plus 100 mg CoQ10 daily, matching for their baseline characteristics, and were assessed for frequency and severity of attacks, and ≥50 % reduction in attack frequency per month. Thirty-six and 37 patients were analyzed in CoQ10 and control groups, respectively. Number of attacks per month dropped significantly in the CoQ10 group (mean decrease: 1.6 vs. 0.5 among CoQ10 and control groups, respectively, p < 0.001). A significant reduction was also evident in the severity of headaches (mean decrease: 2.3 vs. 0.6 among CoQ10 and control groups, respectively, p < 0.001). For ≥50 % reduction in the frequency of attacks per month, the number needed to treat was calculated as 1.6. No side effects for CoQ10 were observed. This study suggests that CoQ10 might reduce the frequency of headaches, and may also make them shorter in duration, and less severe, with a favorable safety profile. Be well! JP

    Coenzyme Q10 and pro-inflammatory markers in children with Down syndrome: clinical and biochemical aspects.

    OBJECTIVE: Evidence of oxidative stress was reported in individuals with Down syndrome. There is a growing interest in the contribution of the immune system in Down syndrome. The aim of this study is to evaluate the coenzyme Q10 and selected pro-inflammatory markers such as interleukin 6 and tumor necrosis factor α in children with Down syndrome.

    METHODS: Eighty-six children (5-8 years of age) were enrolled in this case-control study from two public institutions. At the time of sampling, the patients and controls suffered from no acute or chronic illnesses and received no therapies or supplements. The levels of interleukin 6, tumor necrosis factor α, coenzyme Q10, fasting blood glucose, and intelligence quotient were measured.

    RESULTS: Forty-three young Down syndrome children and forty-three controls were included over a period of eight months (January-August 2014). Compared with the control group, the Down syndrome patients showed significant increase in interleukin 6 and tumor necrosis factor α (p=0.002), while coenzyme Q10 was significantly decreased (p=0.002). Also, body mass index and fasting blood glucose were significantly increased in patients. There was a significantly positive correlation between coenzyme Q10 and intelligence quotient levels, as well as between interleukin 6 and tumor necrosis factor α.

    CONCLUSION: Interleukin 6 and tumor necrosis factor α levels in young children with Down syndrome may be used as biomarkers reflecting the neurodegenerative process in them. Coenzyme Q10 might have a role as a good supplement in young children with Down syndrome to ameliorate the neurological symptoms.

    A combination of coenzyme Q10, feverfew and magnesium for migraine prophylaxis: a prospective observational study.

    BACKGROUND: Feverfew (Tanacetum parthenium L.), magnesium and coenzyme Q10 are frequently used for migraine prophylaxis. Supplementation with a fixed combination of these three agents (Antemig®, PiLeJe) was investigated in an observational study.

    METHODS: Adult patients suffering from migraine according to the criteria of the International Headache Society were enrolled by general practitioners (≥2 migraine attacks during previous month; exclusion of chronic migraine and medication overuse) and after a one-month baseline phase, supplemented with one tablet of 100 mg feverfew, 100 mg coenzyme Q10 and 112.5 mg magnesium per day for 3 months.

    Supplementation significantly reduced the number of days with migraine headache during third month of supplementation compared to baseline phase (1.3 days ±1.5 versus 4.9 days ±2.6, p < 0.0001; n = 68 intention to treat; primary criterion). The decrease was progressive over the period of supplementation and significant from first month (1st month: -2.5 days ±3.1, p < 0.0001; 2nd month: -3 days ±2.8, p < 0.0001). The proportion of patients with a reduction of at least 50% in the number of days with migraine headache was 75% (51/68) after 3 months, with a progressive increase over the period of supplementation (63.2% [43/68] after 1 month and 70.6% [48/68] after 2 months). The proportion of patients with anxiety and depressive symptoms (Hospital Anxiety and Depression Scale) decreased between baseline phase and third month of supplementation from 61.9% (39/63 patients with information available) to 35% (21/60) for depression and from 52.4% (33/63) to 30% (18/60) for anxiety. An improvement of quality of life (Qualité de Vie et Migraine questionnaire) was also observed. The combination was well tolerated. CONCLUSIONS: Results suggest that the proprietary supplement containing feverfew, coenzyme Q10 and magnesium assessed could be beneficial and safe for the prevention of migraine in adult patients and merits further study.

    The Effects of Coenzyme Q10 Supplementation on Glucose Metabolism, Lipid Profiles, Inflammation, and Oxidative Stress in Patients With Diabetic Nephropathy: A Randomized, Double-Blind, Placebo-Controlled Trial.

    OBJECTIVE: Data on the effects of coenzyme Q10 (CoQ10) supplementation on glucose metabolism, lipid profiles, inflammation, and oxidative stress in subjects with diabetic nephropathy (DN) are scarce. This research was done to determine the effects of CoQ10 supplementation on metabolic status in subjects with DN.

    METHODS: This randomized double-blind placebo-controlled clinical trial was done in 50 subjects with DN. Participants were randomly assigned into two groups to intake either 100 mg/day CoQ10 supplements (n = 25) or placebo (n = 25) for 12 weeks. Fasting blood samples were obtained at first and after 12-week intervention to quantify metabolic profiles.

    RESULTS: After 12 weeks of treatment, compared with the placebo, CoQ10 supplementation resulted in significant decreases in serum insulin levels (-3.4 ± 6.8 vs +0.8 ± 6.4 µIU/mL, p = 0.02), homeostasis model of assessment-estimated insulin resistance (-1.0 ± 2.0 vs +0.2 ± 1.8, p = 0.03), homeostasis model of assessment-estimated B cell function (-12.3 ± 26.3 vs +3.5 ± 23.1, p = 0.02) and HbA1c (-1.1 ± 1.0 vs -0.1 ± 0.2%, p < 0.001), and a significant improvement in quantitative insulin sensitivity check index (+0.009 ± 0.01 vs -0.006 ± 0.01, p = 0.01). In addition, CoQ10 supplementation significantly decreased plasma malondialdehyde (MDA) (-0.6 ± 0.5 vs +0.5 ± 1.0 µmol/L, p < 0.001) and advanced glycation end products levels (AGEs) (-316.4 ± 380.9 vs +318.6 ± 732.0 AU, p < 0.001) compared with the placebo. Supplementation with CoQ10had no significant impacts on fasting plasma glucose (FPG), lipid profiles, and matrix metalloproteinase-2 (MMP-2) compared with the placebo. CONCLUSIONS: Taken together, our study demonstrated that CoQ10 supplementation for 12 weeks among DN patients had favorable effects on glucose metabolism, MDA, and AGEs levels, but unchanged FPG, lipid profiles, and MMP-2 concentrations.

    Effects of 12-week supplementation of marine Omega-3 PUFA-based formulation Omega3Q10 in older adults with prehypertension and/or elevated blood cholesterol.

    BACKGROUNDS: To study the effects of supplementation of a marine omega-3 poly-unsaturated fatty acids (n3-PUFA) formulation (Omega3Q10) in older adults with hypertension and/or hypercholesterolemia.

    METHODS: A total of 97 people were enrolled to receive 12-week supplementation of either Omega3Q10 (n = 48) or soybean oil (n = 49). Total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and hypertension-related symptoms were determined before and after the supplementation.

    RESULTS: There were no baseline differences between the two groups. Omega3Q10 supplementation significantly reduced diastolic blood pressure (DBP) (from 81.6 ± 5.3 mmHg to 79.3 ± 5.2 mmHg, P < 0.05). Blood concentrations of TC and LDL-C decreased significantly and blood HDL-C level increased significantly after 12 weeks of Omega3Q10 (5.5 ± 0.7 vs. 5.3 ± 0.5, P < 0.05; 3.7 ± 0.8 vs. 3.3 ± 0.6, P < 0.05; 1.2 ± 0.6 vs. 1.3 ± 0.5, P < 0.05, respectively) and soybean oil supplementation (5.7 ± 0.8 vs. 5.6 ± 0.7, P < 0.05; 3.6 ± 0.7 vs. 3.4 ± 0.8, P < 0.05; 1.0 ± 0.8 vs. 1.2 ± 0.7, P < 0.05, respectively) but no group differences were found. A significantly greater proportion of the people in the Omega3Q10 group became free from headache and palpitations & chest tightness symptoms after the 12-week supplementation compared to that of the soybean oil group (95.5% vs. 71.4%, P < 0.01; 95.8 vs. 75.5%, P < 0.01, respectively). CONCLUSION: 12-week supplementation of Fish oil-based PUFA appear to be more effective in improving DBP and hypertension-related symptoms than soybean oil in old adults with hypertension and hypercholesterolemia although both supplementation improved TC, LDL-C and HDL-C concentrations.

    Oral coenzyme Q10 supplementation in patients with migraine: Effects on clinical features and inflammatory markers.

    BACKGROUNDS AND AIMS: Migraine and inflammation are correlated. Coenzyme Q10 (CoQ10) as an anti-inflammatory agent has shown useful effects in other diseases. The present study aimed to assess the effect of CoQ10 supplementation on inflammation and clinical features of migraine.

    METHODS: This randomized double-blind placebo-controlled clinical trial was conducted among 45 non-menopausal women aged 18-50 years, diagnosed for episodic migraine according to the International Headache Society. After one month run-in period, subjects received CoQ10 (400 mg/day CoQ10, n = 23) or placebo (wheat starch, n = 22) for three months. All the patients got prophylactic medication too. Serum CoQ10 concentration, Calcitonin gene-related peptide (CGRP), interleukin (IL)-6, IL-10 and tumor necrosis factor-α (TNF-α) were measured at the beginning and end of the study.

    RESULTS: CoQ10 supplementation reduced CGRP and TNF-α significantly (p = 0.011 and p = 0.044, respectively), but there were no significant differences in serum IL-6 and IL-10 between the two groups. Significant increase in serum CoQ10 levels was evident with CoQ10 therapy (P < 0.001). A significant improvement was found in frequency (p = 0.018), severity (p = 0.001) and duration (p = 0.012) of migraine attacks in CoQ10 group compared to placebo. CONCLUSION: CoQ10 supplementation may decrease CGRP and TNF-α with no favorable effects on IL-6 and IL-10 in patients with migraine. Be well! JP

    Treatment of coenzyme Q10 for 24 weeks improves lipid and glycemic profile in dyslipidemic individuals.

    BACKGROUND: The use of coenzyme Q10 (CoQ10) as an adjuvant treatment with routine clinical therapy against metabolic diseases has shown benefit. However, the effect of CoQ10 as a primary preventive agent against cardiovascular diseases (CVDs) has not been well studied.

    OBJECTIVE: The objective of this study was to investigate the effect of CoQ10 on CVD risk factors in dyslipidemic patients.

    METHODS: In this randomized, double-blinded, placebo-controlled trial, 101 dyslipidemic subjects without taking any hypoglycemic or hypolipidemic drugs were administrated to 120 mg CoQ10 or placebo daily for 24 weeks. Anthropometric parameters, lipid and glycemic profile, biomarkers of inflammation, and antioxidant capacity were evaluated before and after 12 and 24 weeks of intervention.

    RESULTS: All 101 subjects were included in the analysis. On the 12th week, compared to placebo, CoQ10 supplementation decreased systolic (P = .010) and diastolic pressure (P = .001) and increased serum total antioxidant capacity (TAC; P = .003). On the 24th week, compared to placebo, CoQ10 supplementation further lowered blood pressure and TAC, reduced triglyceride (P = .020) and low-density lipoprotein cholesterol (P = .016), and increased ApoA-I (P < .001) while decreasing homeostasis model assessment of insulin resistance index (P = .009). Adjustment for change of physical activity and energy intake did not alter the effect of CoQ10 on the aforementioned parameters but led to significant decrease of non-high-density lipoprotein cholesterol in CoQ10 group compared to placebo (P = .031). CONCLUSIONS: Twenty-four-week treatment of CoQ10 ameliorates multiple CVD risk factors. The versatility and safety of CoQ10 makes it a potential candidate for the primary prevention of CVD. Be well!

    Supplementation with Qter® and Creatine improves functional performance in COPD patients on long term oxygen therapy.

    BACKGROUND: Skeletal muscle dysfunction and poor functional capacity are important extra-pulmonary manifestations of chronic obstructive pulmonary disease (COPD), especially in COPD patients on long-term O2 therapy (LTOT). Beside the role of pulmonary rehabilitation, the effect of nutritional interventions is still controversial, and there are knowledge gaps on the effective role of nutraceutical supplementation on hard endpoints. The aim of this study was to investigate the effects of nutritional supplementation with Coenzyme Q10 (QTer®) – a powerful antioxidant with the potential to reduce oxidative stress and improve mitochondrial function - and Creatine on functional, nutritional, and metabolomic profile in COPD patients on long-term O2 therapy.

    METHODS: One-hundred and eight patients with COPD from 9 Italian hospitals were enrolled in this double-blinded randomized placebo-controlled clinical study. At baseline and after 2 months of therapy, the patients underwent spirometry, 6-minute walk test (6MWT), bioelectrical impedance analysis, and activities of daily living questionnaire (ADL). Also, dyspnea scores and BODE index were calculated. At both time points, plasma concentration of CoQ10 and metabolomic profiling were measured.

    FINDINGS: Ninety patients, who randomly received supplementation with QTer® and Creatine or placebo, completed the study. Compared with placebo, supplemented patients showed improvements in 6MWT (51 ± 69 versus 15 ± 91 m, p < 0.05), body cell mass and phase angle, sodium/potassium ratio, dyspnea indices and ADL score. The CoQ10 plasma concentration increased in the supplementation group whereas it did not change in the placebo group. The metabolomics profile also differed between groups. Adverse events were similar in both groups. INTERPRETATION: These results show that in patients with COPD, dietary supplementation with CoQ10 and Creatine improves functional performance, body composition and perception of dyspnea. A systemic increase in some anti-inflammatory metabolites supports a pathobiological mechanism as a reason for these benefits. Further trials should help clarifying the role of QTer® and Creatine supplementation in patients with COPD. Be well! JP

    A Pilot Clinical Study of Liquid Ubiquinol Supplementation on Cardiac Function in Pediatric Dilated Cardiomyopathy.

    BACKGROUND: Pediatric dilated cardiomyopathy (PDCM) is a life-threatening type of cardiac muscle dysfunction in children. Ubiquinone is a lipid-soluble nutrient that participates in energy synthesis. Recently, a novel hydrophilic ubiquinol supplement was developed. The purpose of this study was to assess the effect of liquid ubiquinol supplementation (10 mg/kg body weight/day) on cardiac function in children with PDCM.

    METHODS: Ten children diagnosed with PDCM were recruited to this study and administered with liquid ubiquinol for 24 weeks. The cardiac function was measured by echocardiography. The New York Heart Association (NYHA) functional classification was used to assess symptoms of heart failure. Plasma coenzyme Q10 levels were measured during the study.

    RESULTS: Ejection fraction (EF) and fractional shortening (FS) were significantly higher than the baseline values until week 16 of supplementation. Subjects who had higher plasma coenzyme Q10 concentration had significantly better EF and FS values. In addition, 30% of the subjects showed improvement in the NYHA classification after 24 weeks of supplementation.

    CONCLUSION: Liquid ubiquinol supplementation is associated with an increase the level of coenzyme Q10 to complementary improve cardiac function (particularly EF and FS) and ameliorate the symptoms of heart failure in children with PDCM.
