BLUE-GREEN ALGAE (organic Microalgae)

POSSIBLY EFFECTIVE

Hypertension. Oral blue-green algae seem to modestly reduce blood pressure in patients with hypertension. Details: Some small clinical studies show that blue-green algae can decrease blood pressure in patients with hypertension (97206,99654). A meta-analysis of five small clinical trials in patients with hypertension, type 2 diabetes, or chronic pain shows that taking spirulina blue-green algae 1-8 grams daily for up to 12 weeks reduces systolic blood pressure (SBP) by 5 mmHg and diastolic blood pressure (DBP) by 7 mmHg when compared with placebo. The effect size was larger in patients with hypertension and in those treated for at least 12 weeks (109964). Another small clinical study shows that taking spirulina blue-green algae (A. maxima) 4.5 grams daily for 6 weeks decreases blood pressure in adults with hypertension, with the number of subjects fulfilling the criteria for hypertension decreasing from 45% to 14% when compared to baseline (18297). A more recent clinical study in patients with hypertension shows that consuming a salad dressing containing 2 grams spirulina blue-green algae daily for 8 weeks reduces SBP by around 6 mmHg and DBP by around 4 mmHg when compared to baseline. While overall reduction in blood pressure with spirulina dressing was larger when compared with patients consuming a control dressing, the study groups were heterogenous at baseline, limiting the validity of any statistical comparisons between groups (109965).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Allergic rhinitis (hay fever). It is unclear if oral blue-green algae are beneficial in allergic rhinitis. Details: Preliminary clinical research shows that taking spirulina blue-green algae (A. platensis) 2 grams daily for 6 months, improves self-rated scores for sneezing, nasal discharge, nasal congestion, and itching when compared with placebo in adults with allergic rhinitis (18300).
Antiretroviral-induced insulin resistance. It is unclear if oral blue-green algae are beneficial for insulin resistance due to antiretrovirals. Details: Preliminary clinical research shows that taking spirulina blue-green algae (A. platensis) 19 grams daily for 2 months increases insulin sensitivity by about 225% when compared to baseline in patients with antiretroviral-induced insulin resistance (75944). The validity of this finding is limited by the lack of a comparator group.
Anxiety. Although there has been interest in using oral blue-green algae for anxiety, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Arsenic poisoning. It is unclear if oral blue-green algae are beneficial for chronic arsenic toxicity. Details: Preliminary clinical research in people living in areas of Bangladesh with high arsenic levels in drinking water shows that taking a combination of an alcoholic extract of spirulina blue-green algae 250 mg and zinc 2 mg orally twice daily for 16 weeks, in addition to use of filtered drinking water, increases urinary arsenic excretion, reduces hair arsenic levels, and improves skin manifestations of chronic arsenic toxicity when compared with placebo plus filtered water (18301).
Athletic performance. Most research suggests that oral blue-green algae are not beneficial for improving athletic performance; however, the available studies are small. Details: AAlthough some research disagrees, most small or preliminary clinical trials show that taking spirulina blue-green algae does not improve athletic performance in trained or untrained adults. One study shows that, when compared with placebo, taking spirulina blue-green algae (Hawaiian Spirulina, Cyanotech Corporation) 3 grams daily for up to 8 weeks has no effect on exercise output during a 30-minute elliptical trainer workout in active males (97203). In elite rugby players, taking spirulina blue-green algae (Algae Green Value) 5.7 grams daily for 7 weeks does not improve jump or sprint performance or body composition when compared to placebo (104567). In healthy untrained males, a small study shows that taking spirulina blue green algae 6 grams daily for 7 days does not increase the time to fatigue related to arm cycling following a 30-minute submaximal exercise bout (104566). In male recreational runners, spirulina blue-green algae (A. platensis) 2 grams three times daily for 4 weeks was not associated with any change in exercise intensity during a 2-hour treadmill jogging period. However, sprinting time to exhaustion following the 2-hour jog increased from 2.05 minutes to 2.7 minutes (18306). Also, a study of athletes and non-athletes shows that taking spirulina blue-green algae (Parry Nutraceuticals) 2 grams daily for 8 weeks has a small effect on isometric muscle strength, but not muscle endurance, when compared with placebo (104568).
Attention deficit-hyperactivity disorder (ADHD). Oral blue-green algae have only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking 3 mL of a specific combination of spirulina blue-green algae, peony, ashwagandha, gotu kola, bacopa, and lemon balm (Nurture and Clarity, Tree of Healing-LD) diluted in 50-60 mL of water three times daily for 4 months improves ADHD scores when compared with placebo in previously untreated children aged 6-12 years (19272). It is unclear if this effect is due to blue-green algae, other ingredients, or the combination.
Beta-thalassemia. It is unclear if oral blue-green algae are beneficial in beta-thalassemia. Details: In children with beta-thalassemia, preliminary clinical research shows that taking spirulina blue-green algae (GNC Natural Brand Spirulina, General Nutrition Corporation) 250 mg/kg daily, up to a maximum dose of 4 grams daily, for 3 months reduces the percentage of children requiring blood transfusion during an interval of less than 2 weeks from 66% to 40%. There were also improvements in red blood cell count and levels of hemoglobin, ferritin, and liver function enzymes (104569). However, the validity of these findings is limited by the lack of a comparator group.
Blepharospasm. It is unclear if oral blue-green algae are beneficial when used in conjunction with botulinum toxin injections. Details: Preliminary clinical research shows that taking a specific product containing the blue-green algae species Aphanizomenon flos-aquae (Super Blue-Green Algae, Cell Tech) 1500 mg per day orally for 6 months in addition to botulinum toxin-A injections does not reduce eyelid spasms when compared with botulinum toxin-A alone in people with essential blepharospasm or Meige syndrome (14842).
Cancer. Although there has been interest in using oral blue-green algae for cancer, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Cardiovascular disease (CVD). Although there has been interest in using oral blue-green algae for CVD, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Cognitive Impairment. It is unclear if oral blue-green algae are effective for improving cognitive impairment. Details: A small clinical study in patients aged 60 or older with mild cognitive impairment shows that taking blue-green algae extract 1 gram 3 times daily for 12 weeks slightly improves some components of cognitive function testing related to visual learning, memory, and vocabulary when compared with placebo (112001). However, the validity of these findings is limited by lack of adjustment for multiple comparisons, which may explain the discrepant results with the other components of the cognitive function tests.
Depression. Although there has been interest in using oral blue-green algae for depression, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Diabetes. It is unclear if oral blue-green algae are beneficial in diabetes. Details: A meta-analysis of seven small clinical studies in patients with type 2 diabetes shows that taking spirulina blue-green algae 0.8-14 grams daily for 6-12 weeks reduces fasting blood glucose and improves total cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol, but does not affect low-density lipoprotein (LDL) cholesterol, when compared with placebo. There was no reduction in glycated hemoglobin (HbA1c); however, all but two of the studies lasted less than 12 weeks, limiting the validity of the findings related to HbA1c (109970).
Dyslipidemia. It is unclear if oral blue-green algae are beneficial in dyslipidemia. Details: Several clinical studies in patients with normal or elevated cholesterol levels show that doses of spirulina blue-green algae (A. platensis, A. maxima, A. fusiformis) ranging from 1-10 grams daily for 1-6 months may reduce total cholesterol by 8% to 27%, low-density lipoprotein (LDL) cholesterol by 10% to 65%, and triglycerides by 0% to 23%; and increase high-density lipoprotein (HDL) cholesterol by 0% to 66% (18297,18298,18299,91705,91708,91710,91717,102689). However, the validity of these studies is limited by methodological weaknesses and heterogeneous population characteristics. A meta-analysis of 23 small studies, several of which were in patients with type 2 diabetes or obesity, shows that taking blue-green algae 0.8-10 grams for 4 to 24 weeks modestly improves levels of LDL, HDL, triglycerides, and total cholesterol when compared with placebo or no treatment (112004). The interpretation of these findings is limited by the high heterogeneity of the included studies which enrolled patients of varying health status and employed various study designs.
Dyspepsia. Although there has been interest in using oral blue-green algae for dyspepsia, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Exercise-induced muscle soreness. It is unclear if oral blue-green algae are effective for the prevention of exercise-induced muscle soreness. Details: A small clinical study in recreationally trained males shows that taking spirulina blue-green algae 2 grams three times daily does not reduce delayed onset muscle soreness after eccentric exercise when compared with placebo (109967).
Hepatitis C. Evidence for the use of oral blue-green algae in hepatitis C is conflicting. Details: One clinical study in adults with chronic hepatitis C who are unresponsive to interferon treatment shows that taking spirulina blue-green algae (A. platensis) 500 mg orally three times daily for 6 months is associated with greater improvements in alanine aminotransferase (ALT) levels than taking silymarin 140 mg three times daily. Complete virological response rates were 13% with blue-green algae and 3% with silymarin, although this difference was not statistically significant (63247). However, in another study in people with chronic hepatitis B or C, liver function enzyme levels worsened after one month of treatment with oral spirulina blue-green algae (18304).
HIV/AIDS. It is unclear if oral blue-green algae are beneficial for people with HIV/AIDS who do not have access to antiretrovirals. Details: One clinical study in adults with untreated HIV shows that taking spirulina blue-green algae (A. platensis) powder 5-10 grams daily for 3-6 months does not affect CD4 counts, viral load, or weight gain in patients with HIV (75927,91707). However, in one study, the incidence of opportunistic infections, respiratory disease, gastrointestinal symptoms, and fatigue was 43% for patients taking spirulina blue-green algae, compared to 70% for patients taking placebo (91707).
Iron deficiency anemia. Although there has been interest in using oral blue-green algae for iron deficiency anemia, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Lichen planus. It is unclear if oral blue-green algae are beneficial in patients with oral lichen planus. Details: A small clinical study in patients with oral lichen planus shows that taking spirulina blue-green algae 500 mg twice daily for 8 weeks along with application of triamcinolone acetonide 0.1% oral paste three times daily for 1 week reduces pain and lesion size when compared with only triamcinolone acetonide three times daily for 8 weeks (109963).
Malnutrition. Evidence for the use of oral blue-green algae in malnutrition is conflicting. Details: Some clinical research in severely undernourished children shows that adding spirulina blue-green algae (A. platensis) 5 grams orally twice daily for 8 weeks to a traditional diet results in an average daily weight gain of 25 grams, compared with only 15 grams for those given the traditional diet alone. Similarly, giving blue-green algae 10 grams twice daily for 8 weeks in addition to a misola diet (millet, soy, peanut kernel, sugar, and salt) results in an average daily weight gain of 34 grams, compared with only 20 grams for children given the misola diet alone (18308). However, a small clinical study in malnourished children aged 3 months to 3 years shows that giving spirulina blue-green algae 5 grams daily for 3 months in addition to a traditional diet fails to increase weight gain more than the traditional diet alone (18309). Similarly, a moderate-size crossover study in preschool-aged children in Cambodia shows that taking blue-green algae 2 grams 5 times a week during the first hour of school for 8 weeks does not improve weight gain or height but may reduce the proportion of children with anemia when compared with placebo (112002). The interpretation of these findings is limited by the high rate of patients lost to follow-up and the lack of statistical adjustment for confounding factors, such as parasitism and home diet.
Memory. Although there has been interest in using oral blue-green algae for memory, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Menopausal symptoms. It is unclear if oral blue-green algae are beneficial for improving symptoms of menopause. Details: A preliminary clinical study shows that taking a product containing the blue-green algae species Aphanizomenon flos-aquae (Klamin, Nutrigea) 1.6 grams daily for 8 weeks reduces anxiety and depression when compared with placebo in menopausal adults aged 50-60 years. The treatment has no effect on vasomotor symptoms or hormone levels (18310).
Mental alertness. It is unclear if oral blue-green algae are beneficial for reducing mental fatigue. Details: A preliminary clinical study shows that taking spirulina blue-green algae (Hawaiian Spirulina, Cyanotech Corporation) 3 grams daily for up to 8 weeks improves performance on a mathematical based mental fatigue test in healthy men when compared with placebo. Subjective improvement in mental alertness over placebo was also reported (97203).
Metabolic syndrome. It is unclear if oral blue-green algae are beneficial in patients with metabolic syndrome. Details: A small clinical study in patients with metabolic syndrome shows that taking spirulina blue-green algae (Spirulysat, AlgoSource), providing phycocyanin 20 mg, daily for 12 weeks improves triglyceride levels, but does not reduce body mass index, waist circumference, blood pressure, glycemic indices, or other lipid levels, when compared with placebo (109971).
Nonalcoholic fatty liver disease (NAFLD). Although there has been interest in using oral blue-green algae for NAFLD, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Obesity. Evidence for the use of blue-green algae in obesity is conflicting. Details: Small, low-quality clinical trials have shown mixed results in people with obesity (18295,91717,97205,99655,99703,102688). When results are analyzed together, there is evidence of a very small benefit for both body weight and plasma lipid levels. Two meta-analyses show that taking spirulina blue-green algae may increase weight loss by up to 1.85 kg when compared with placebo (102690,104565). A greater effect is seen in patients with obesity when compared with overweight patients. In addition, there is a small effect on fat loss (102690). However, there is evidence from two studies lasting longer than 12 weeks that taking blue-green algae may slightly increase BMI (104565). A meta-analysis of small clinical trials also shows that taking spirulina blue-green algae reduces fasting blood sugar and total cholesterol levels by a small amount when compared with placebo, but has no effect on low-density lipoprotein (LDL) cholesterol or triglyceride levels, in patients with obesity (102689). When combined with an exercise program, taking spirulina blue-green algae increases weight loss by 1.4 kg and improves exercise tolerance and total, LDL, and high-density lipoprotein (HDL) cholesterol levels when compared with exercise alone (99655,102688). Doses have included a specific product containing the spirulina blue-green algae species A. fusiformis (Multinal, New Ambadi Estate Pvt. Ltd.) 1 gram twice daily or four times daily for 3 months (91717) or spirulina blue-green algae 2 grams daily for 3 months, or 4.5 grams daily for 6 weeks, alone or in combination with exercise (97205,99655,102688).
Oral leukoplakia. It is unclear if oral blue-green algae are beneficial for oral leukoplakia in tobacco chewers. Details: Preliminary clinical research shows that taking spirulina blue-green algae (A. fusiformis) orally 1 gram daily for 12 months produces regression of precancerous oral leukoplakia lesions in 45% of tobacco chewers, compared to only 7% of those receiving placebo. Regression rates appear to be highest in those with homogeneous lesions and lowest in those with ulcerated or nodular lesions (15782).
Periodontitis. It is unclear if injecting blue-green algae into periodontal pockets is beneficial in periodontitis. Details: Preliminary clinical research shows that injecting a 4% w/v gel prepared from spirulina blue-green algae into periodontal pockets of adults with chronic periodontitis, after scaling and root planing, is associated with a decrease in probing pocket depth of 1.57 mm after 120 days, compared with only 0.84 mm in patients receiving scaling and root planing alone (91709).
Premenstrual syndrome (PMS). Although there has been interest in using oral blue-green algae for PMS, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Stress. Although there has been interest in using oral blue-green algae for stress, there is insufficient reliable information about the clinical effects of blue-green algae for this condition.
Ulcerative colitis. It is unclear if oral blue-green algae are beneficial in patients with ulcerative colitis. Details: A small clinical study in patients with ulcerative colitis shows that taking spirulina blue-green algae 500 mg twice daily for 8 weeks improves quality of life scores and reduces stress and sleep disturbances when compared with placebo. However, there was no effect on most measures of sleep quality, mood, and fatigue (109969).
Wound healing. Although there has been interest in using oral blue-green algae for wound healing, there is insufficient reliable information about the clinical effects of blue-green algae for this condition. More evidence is needed to rate blue-green algae for these uses.

COCONUT OIL (organic virgin Coconut Oil)

POSSIBLY EFFECTIVE

Atopic dermatitis (eczema). Topical coconut oil has been evaluated for the management of atopic dermatitis in children, with promising results. Details: One clinical trial in children with atopic dermatitis shows that topical application of virgin coconut oil 5 mL twice daily for 8 weeks results in moderate or excellent improvements in almost two-fold more patients and reduces symptom severity about 30% when compared with mineral oil (90614).
Prematurity. Topical coconut oil may reduce the risk for hypothermia and apnea and improve body weight, length, and skin integrity in premature infants. Details: A large clinical study in premature infants shows that applying coconut oil 5 mL topically four times daily for 28 days reduces the incidence of hypothermia and apnea by 67% and 76%, respectively, when compared with body massage without oil. There were also improvements in the level of vitamin D3 and the overall neurodevelopmental score over 12 months (101873). Clinical studies in premature infants also show that oil massage using coconut oil reduces weight loss in the first few days after birth and improves weight gain and length when compared with mineral oil or no application (17937,90616,101873). Preterm infants are at increased risk for infection due to the inadequate protective barrier provided by immature skin. Clinical studies in preterm or very preterm infants show that topical application of virgin coconut oil 2-4 times daily for 21-28 days as part of routine neonatal care helps maintain skin integrity, but does not reduce the risk for infections such as sepsis, when compared with routine neonatal care alone (96204,101873). Another clinical study in preterm infants shows that topical application of coconut oil 5 mL/kg twice daily for 28 days reduces the incidence of hospital-acquired infections from 21% to 7% when compared with control, but does not reduce overall mortality (90616).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Alzheimer disease. Although there has been interest in using oral coconut oil for Alzheimer disease, there is insufficient reliable information about the clinical effects of coconut oil for this purpose.
Athletic performance. It is unclear if oral coconut oil is beneficial for improving athletic performance. Details: A small clinical trial in recreational runners shows that taking virgin coconut oil (Copra Alimentos, Maceio) 15 grams, with or without caffeine 6 mL/kg, 60 minutes prior to a 1600 meter running trial does not improve running performance or ratings of exertion when compared with a warm water control (101874).
Breast cancer. It is unclear if oral coconut oil is beneficial in patients with breast cancer. Details: A small clinical study in patients with invasive or advanced breast cancer shows that taking virgin coconut oil 10 mL twice daily starting one week after chemotherapy from the third to the sixth cycle improves quality of life based on some but not all measurement scales when compared with control (90615).
Coronary heart disease (CHD). Small clinical studies suggest that oral coconut oil does not alter the risk of CHD or prevent cardiovascular events in patients with CHD. Details: One small observational study in India has found that coconut or coconut oil consumption is not associated with a decreased or increased risk of myocardial infarction or angina (14407). A small clinical trial in patients with CHD from India shows that cooking with coconut oil does not alter cardiovascular outcomes or risk factors at 6 months, 1 year, or 2 years when compared with cooking with sunflower oil (96205).
Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral coconut oil for COVID-19, there is insufficient reliable information about the clinical effects of coconut oil for this purpose.
Crohn disease. Although there has been interest in using oral coconut oil for Crohn disease, there is insufficient reliable information about the clinical effects of coconut oil for this purpose.
Dental plaque. Small clinical studies suggest that pulling coconut oil through the teeth may modestly reduce dental plaque. Details: A small clinical study shows that pulling coconut oil 10 mL through the teeth for 15-20 minutes twice daily for 4 days is as effective as using a mouth rinse containing chlorhexidine gluconate-0.2% as 10 mL twice daily for 30 seconds in the prevention of plaque regrowth in posterior, but not anterior, surfaces of the teeth (101878). Another small clinical study in patients with plaque-induced gingivitis shows that pulling coconut oil 10 mL through the teeth for 5-10 minutes nightly for 30 days improves plaque scores when compared with standard dental hygiene with no mouth rinse (106491).
Diabetes. It is unclear if oral coconut oil is beneficial for diabetes. Details: A meta-analysis of clinical trials shows that a single intake of coconut oil as part of a meal modestly increases postprandial glucose levels and decreases insulin levels. However, long-term intake of coconut oil increases insulin resistance, with no effect on fasting blood glucose or insulin levels. Only two studies in these analyses included patients with diabetes (107667). Therefore, the effect of coconut oil in patients with diabetes is unclear.
Diarrhea. It is unclear if oral coconut oil is beneficial for improving diarrhea in children. Details: One small clinical study in children with mild-to-moderate dehydration due to diarrhea shows that eating a diet consisting of coconut oil, chicken, and plantain reduces the duration of diarrhea by 20 hours when compared with a cow's milk diet (19269). However, another small clinical trial in children with acute gastroenteritis shows that total duration of diarrhea is no different in children given a milk-free formula containing coconut oil when compared with children given cow's milk formula (19270).
Dry mouth. It is unclear if topical coconut oil is beneficial for improving dry mouth in patients receiving radiation therapy. Details: One small clinical study in patients with dry mouth caused by radiation therapy shows that coating the mouth with coconut oil prior to meals and at bedtime for 2 weeks does not improve dry mouth-related quality of life scores when compared to baseline (106490).
Dry skin. It is unclear if topical coconut oil is beneficial for improving dry skin. Details: A small clinical study in patients with mild-to-moderate dry skin shows that applying coconut oil topically twice daily improves skin moisture and skin lipid levels when compared to baseline. Coconut oil seems to be comparable to mineral oil as a skin moisturizer (17936). Also, preliminary clinical research in individuals who apply alcohol-based sanitizers to the hands six times daily shows that applying 6-8 drops (0.1 mL/cm²) of virgin coconut oil to the hands before bed for 15 days modestly increases perceived moisture content, but not perceived appearance or sensation, when compared with not using coconut oil (107668).
Fetal and premature infant mortality. It is unclear if topical coconut oil is beneficial for reducing mortality in premature infants. Details: One clinical study in preterm infants shows that topical application of coconut oil 5 mL/kg twice daily for 28 days reduces the incidence of hospital-acquired infections from 21% to 7% when compared with control, but does not reduce overall mortality (90616).
Gingivitis. It is unclear if pulling coconut oil through the teeth is beneficial in patients with gingivitis. Details: A small clinical study in patients with plaque-induced gingivitis shows that pulling coconut oil 10 mL through the teeth for 5-10 minutes nightly for 30 days improves gingival bleeding scores when compared with standard dental hygiene without a mouth rinse (106491). Another small clinical study in volunteers with gingival inflammation shows that pulling extra virgin coconut oil, 5 mL, through the teeth for 8 minutes daily for 28 days does not change plaque microbial counts when compared with baseline or with palm oil pulling (110010).
HIV/AIDS. Although there has been interest in using oral coconut oil for HIV/AIDS, there is insufficient reliable information about the clinical effects of coconut oil for this purpose.
Hypertension. It is unclear if oral coconut oil is beneficial in patients with hypertension. Details: One small clinical study in patients with hypertension shows that taking extra virgin coconut oil 3 mL with breakfast, 4 mL with lunch, and 3 mL with dinner daily for 30 days does not reduce blood pressure when compared with placebo (106493).
Irritable bowel syndrome (IBS). Although there has been interest in using oral coconut oil for IBS, there is insufficient reliable information about the clinical effects of coconut oil for this purpose.
Lice. Topical coconut oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study in children with head lice shows that application of a topical spray containing coconut oil, anise oil, and ylang ylang oil (Chick-Chack) once every 5 days for three treatments eradicates lice in around 92% of infected children, a rate comparable to children treated with a spray containing permethrin, malathion, piperonyl butoxide, and isododecane (13483). It is unclear if these findings are due to coconut oil, other ingredients, or the combination.
Low birth weight. It is unclear if oral coconut oil is beneficial for improving growth in infants with very low birth weight. Details: One small, open-label clinical trial in very low birth weight infants shows that giving coconut oil 1 mL four times daily in expressed breast milk until 40 weeks corrected age does not increase growth when compared with breast milk alone. The addition of coconut oil also has no effect on head circumference, length, weight, or body fat improvements (101875).
Metabolic syndrome. It is unclear if oral coconut oil is beneficial in patients with metabolic syndrome. Details: One small clinical trial in patients with metabolic syndrome shows that using 30 mL of virgin coconut oil in place of other cooking oils daily for 4 weeks reduces levels of triglycerides, very low-density lipoprotein (VLDL) cholesterol, and fasting plasma glucose and increases high-density lipoprotein (HDL) cholesterol levels when compared with a usual diet. However, levels of total cholesterol and low-density lipoprotein (LDL) cholesterol were increased with coconut oil use. Coconut oil did not alter blood pressure or waist circumference (106494).
Multiple sclerosis (MS). Oral coconut oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in patients with MS shows that taking coconut oil 60 mL in combination with epigallocatechin gallate (EGCG) 800 mg daily for 4 months improves functional capacity, increases muscle mass, and reduces symptoms of anxiety and depression by a small amount when compared to baseline (101876,106492). It is unclear if these findings are due to coconut oil, EGCG, or the combination. Additionally, the validity of these findings is limited by the lack of a comparator group.
Nipple fissures. It is unclear if topical coconut oil is beneficial for nipple fissures in breastfeeding mothers. Details: Preliminary clinical research in breastfeeding primiparous mothers with nipple fissures shows that applying 0.5 mL of virgin coconut oil to the fissures after breastfeeding three times daily for 14 days improves scores on Storr's fissure scale and on a visual analog pain scale, when compared with applying 3 to 4 drops of breastmilk to the nipples after every breastfeeding session (110407).
Nocturnal enuresis. It is unclear if topical coconut oil is beneficial in children with primary nocturnal enuresis. Details: Preliminary clinical research in children aged 6 to 14 years with primary nocturnal enuresis shows that applying coconut oil, 6 drops to the suprapubic, sacral, and flank areas nightly for 4 weeks reduces the mean frequency of urination at 4 weeks and 8 weeks of follow-up, when compared with baseline. Complete resolution occurred in 24 patients receiving coconut oil, and 17 receiving the paraffin oil control. There was no improvement in 5 on coconut oil, and 14 on paraffin oil (110405). However, the validity of these findings is unclear since blinding was compromised by the different oil odors.
Obesity. Although some clinical studies suggest that oral coconut oil may modestly reduce body weight or body mass index (BMI), most research is mixed. Details: A meta-analysis of clinical research shows that taking coconut oil in the diet or as a supplement daily decreases body weight, BMI, and fat mass percent by 0.75 kg, 0.28 kg/m², and 0.35%, respectively, when compared to other oils and fats, usually polyunsaturated oils. However, there was no effect on waist circumference or total fat mass, and significant changes did not occur in more than half of the individual studies (107665). These individual studies were generally small, of low to moderate quality, and utilized a wide range of dosing regimens. Doses of coconut oil used in the individual studies ranged from 7-93 mL or 14% to 15% of daily energy intake and included extra-virgin, virgin, bleached and deodorized, hydrogenated, and ordinary sources. Study durations ranged from 4 weeks to 2 years (17938,17942,99102,107665). Virgin coconut oil is associated with reduced hunger and desire to eat in normal weight subjects, but not in obese subjects, when compared with extra virgin olive oil. It is also associated with reduced energy intake at the next meal when compared with olive oil in obese subjects, but not in normal weight subjects (110406).
Psoriasis. It is unclear if topical coconut oil is beneficial in patients with psoriasis. Details: One small clinical study in patients with psoriasis shows that applying coconut oil to the skin before treatment with ultraviolet B (UVB) or psoralen and ultraviolet A (PUVA) phototherapy does not seem to improve the clearance of psoriasis (12356). More evidence is needed to rate coconut oil for these uses.

COENZYME Q10 (Ubiquinol)

LIKELY EFFECTIVE

Coenzyme Q10 deficiency. Taking coenzyme Q10 orally improves symptomatic deficiency. Details: Rare cases of acquired coenzyme Q10 deficiency with symptoms of weakness, fatigue, and seizures have been reported (8160,8161). In adults, deficiency can be treated with coenzyme Q10 orally, 150-2400 mg daily in up to three divided doses. In children, 30 mg/kg, or 60-250 mg daily in up to three divided doses has been used (8160,8161,89417). Data from several multinational disease registries has also evaluated the use of coenzyme Q10 in patients with primary coenzyme Q10 deficiency, a rare genetic disorder. This data indicates that patients who take coenzyme Q10 supplements have a mean reduction of 88% in proteinuria at 12 months when compared with patients who do not take coenzyme Q10. In patients under 18 years of age with primary deficiency and chronic kidney disease at baseline, taking coenzyme Q10 supplements is associated with a 5-year survival without kidney failure of 62%, compared with 19% for those not taking coenzyme Q10 (108956).
Mitochondrial myopathies. Taking coenzyme Q10 orally seems to reduce symptoms in some patients with genetic and acquired mitochondrial dysfunction. Details: A specific coenzyme Q10 formulation (UbiQGel, Tishcon Corporation) has been evaluated for mitochondrial myopathies, including MELAS (myoclonic epilepsy with lactic acidosis and stroke-like episodes) syndrome, Kearns-Sayre syndrome, and MERRF (myoclonus epilepsy with ragged red fibers). Typical doses are 150-160 mg, or 2 mg/kg, daily, gradually increasing to 3000 mg daily in some cases. The onset of action is slow, with maximal effects around 6 months (8159,8162,8163,8912,11050,44240,97905).

POSSIBLY EFFECTIVE

Congestive heart failure (CHF). Oral coenzyme Q10 may provide benefit to patients with CHF by improving some, but not all, measures of disease severity when given in combination with conventional therapy. Details: Population research has found that CHF is associated with low coenzyme Q10 levels that correlate with severity of disease, and may be a predictor of mortality risk (44059,44220). A 2017 meta-analysis of clinical research shows that taking coenzyme Q10 30-300 mg, or 2 mg/kg, orally daily in two or three divided doses for up to 2 years, in addition to conventional therapy, improves exercise capacity, reduces hospitalizations, and reduces mortality by about 30% when compared with placebo. Other clinical research shows that adding oral coenzyme Q10 seems to improve quality of life and decrease symptoms of CHF such as dyspnea, peripheral edema, enlarged liver, and insomnia in patients with mild to severe (New York Heart Association (NYHA) class II-IV) CHF (6037,6038,6407,6408,6409,8909,12170,43967,43971,44042)(44277,44288,44289,44304,44334,44352,95610,96542). Additional clinical research shows that taking coenzyme Q10 30 mg daily for 1 year in addition to standard care reduces the incidence of atrial fibrillation by about 73% when compared with standard care alone in patients with NYHA class II-IV CHF (95609). However, not all evidence is positive. Some research suggests that coenzyme Q10 does not improve objective measures of CHF, including left ventricular ejection fraction (LVEF), cardiac output, or NYHA classification (5090,5248,6037,6038,43904,43932,96542,43932,97902). It is possible that the benefit of coenzyme Q10 depends on the dose and duration, the severity of CHF, and the specific conventional therapies taken concurrently (43973). A meta-analysis of 11 small, low-quality studies concludes that coenzyme Q10 probably reduces risk of all-cause and cardiovascular mortality, and of hospital admission for CHF, but data on improvement in LVEF or exercise capacity and the risk for myocardial infarction and stroke are inconclusive. However, the included studies used a range of coenzyme Q10 doses, varying concurrent therapy, short follow-up periods, and variable measures of treatment effect (108954). In patients with CHF with preserved ejection fraction (HFpEF) and a LVEF of 50% or greater, taking coenzyme Q10 600 mg daily for 12 weeks reduces B-type natriuretic peptide levels and improves Kansas City Cardiomyopathy Questionnaire (KCCQ) scores, level of vigor, and LVEF when compared with placebo (108959).
Diabetic neuropathy. When taken alone or as add-on treatment with pregabalin, most research suggests that oral coenzyme Q10 reduces symptoms in patients with diabetes and neuropathy. Details: Clinical research shows that taking coenzyme Q10 400 mg orally daily for 12 weeks significantly improves nerve conduction and symptoms of neuropathic pain when compared with placebo in diabetic patients with polyneuropathy (44217). The beneficial effects of coenzyme Q10 have also been investigated as an add-on treatment in patients taking pregabalin 150 mg daily. Clinical research shows that taking coenzyme Q10 100 mg three times daily for 8 weeks reduces pain severity and sleep interference due to pain when compared with placebo. The proportion of patients taking coenzyme Q10 with a decline in pain of at least 50% was 47%, compared with 27% of those taking placebo. Despite these findings, there was no difference in patient global improvement (109391). However, some research disagrees. One clinical trial shows that taking coenzyme Q10 (Health Burst) 200 mg daily for 12 weeks does not affect neuropathic symptoms, including pain, sensations, and strength, when compared with placebo (109386).
Fibromyalgia. Oral coenzyme Q10 seems to improve both physical and psychological symptoms of this condition. Details: Clinical research in women with fibromyalgia shows that taking coenzyme Q10 300-400 mg orally daily for 40 days to 3 months improves pain by 24% to 56%, fatigue by 22% to 47%, sleep disturbances by 33%, morning tiredness by 56%, and tender points by 44% when compared with placebo. Patients also experience an improvement in psychological symptoms, including depression and anxiety (89416,97912,97913).
Ischemia-reperfusion injury. Oral or intravenous coenzyme Q10 may help reduce hypoxic damage during cardiac bypass or vascular surgery. Details: Clinical research shows that taking coenzyme Q10, 150-300 mg orally daily in up to 3 divided doses for 1-2 weeks before cardiac bypass or vascular surgery, or 5 mg/kg IV two hours prior to surgery, reduces hypoxic damage during the surgery (11902,11903,44031,44294). However, coenzyme Q10 has no effect on cardiac function or troponin levels (11904,44292).
Migraine headache. The American Academy of Neurology considers oral coenzyme Q10 to be possibly effective for migraine prevention in adults. Its benefit in children is unclear. Details: Two small open-label, non-randomized clinical trials in adults show that taking coenzyme Q10 100-150 mg daily decreases the frequency of headaches by up to 50% when compared with baseline or control, although it can take up to 3 months to see benefit (8135,95608). Higher quality research suggests a smaller benefit. A meta-analysis of small randomized controlled trials in adults shows that taking coenzyme Q10 alone or with other supplements reduces migraine attacks by 1.5 times per month and reduces duration of migraines by about 12 minutes when compared with control (105070). In children and adolescents, some clinical research shows that taking coenzyme Q10 orally, as 100 mg daily or 1-3 mg/kg daily, for 12-16 weeks does not improve headache frequency, severity, or duration when compared with placebo. However, it may reduce migraine frequency in children with low coenzyme Q10 levels (15256,44197). However, another clinical study shows that taking coenzyme Q10 daily is less effective than amitriptyline after one month, but as effective after 3 months, for improving headache frequency, severity, or duration, as well as quality of life. In this study, the dose of coenzyme Q10 was based on weight; 30 mg daily for children weighing less than 30 kg and 60 mg daily for children weighing at least 30 kg (109388).
Multiple sclerosis (MS). Oral coenzyme Q10 seems to reduce fatigue and depression associated with MS. Details: Clinical research shows that taking coenzyme Q10 500 mg orally daily for 3 months reduces fatigue and depression in patients with MS when compared with placebo (96539).
Muscular dystrophy. Oral coenzyme Q10 seems to improve physical performance in patients with muscular dystrophy of various forms. Details: Two small clinical studies show that taking coenzyme Q10 orally 100 mg daily for 3 months seems to improve physical performance when compared with placebo in some patients with various muscular dystrophies (2127).
Myocardial infarction (MI). Oral coenzyme Q10 seems to reduce cardiac events and improve survival in patients who have had an MI. It is unclear if coenzyme Q10 improves survival in patients after cardiac arrest. Details: One small clinical study in patients with acute MI shows that starting coenzyme Q10 60 mg twice daily within 72 hours of the MI appears to significantly reduce the risk of cardiac events, including non-fatal MI and cardiac death, by 52% when administered for 28 days and by 45% when administered for up to one year (10152,44330). Also, a small clinical study in patients with recent MI who received cardiopulmonary resuscitation, shows that administering a 250 mg loading dose of coenzyme Q10 solution followed by 150 mg three times daily through a nasogastric tube for 5 days improves the 3-month survival rate by 134% when compared with placebo (43935). However, another clinical study in a similar patient population conducted to replicate these results shows that administering coenzyme Q10 300 mg in 50 mL of Ensure every 12 hours for 7 days does not improve in-hospital mortality or neurological outcomes when compared with placebo (105068).
Peyronie disease. Coenzyme Q10 taken orally may reduce Peyronie disease severity. Details: Clinical research shows that, in patients with early chronic Peyronie disease, taking coenzyme Q10 (Kaneka Nutrients, Osaka) 300 mg orally daily for 24 weeks reduces new plaque formation and plaque size and improves erectile function when compared with placebo. Additionally, disease progression is slowed in about 76% of patients (44180).

POSSIBLY INEFFECTIVE

Alzheimer disease. Coenzyme Q10 appears to be ineffective for improving cognition. Details: One clinical study shows that taking coenzyme Q10 1200 mg orally daily for 16 weeks does not improve cognition scores when compared with placebo in patients with Alzheimer disease (19206).
Amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease). Oral coenzyme Q10 does not attenuate functional decline in ALS patients. Details: Clinical research shows that taking coenzyme Q10 2700 mg orally daily for 9 months does not significantly attenuate a decline in ALS functioning scores when compared with placebo (44131). Higher doses, up to 3000 mg daily, have been tolerated by patients with ALS for 5 months, although the effect on ALS functioning at this dose is not known (43955).
Chemotherapy-related fatigue. Oral coenzyme Q10 does not seem to help with fatigue due to chemotherapy. Details: Clinical research shows that taking coenzyme Q10 100 mg orally three times daily for 24 weeks does not reduce chemotherapy-related fatigue or improve quality of life when compared with placebo in breast cancer patients undergoing chemotherapy with or without radiation (89420).
Diabetes. Most clinical research does not show any benefit with oral coenzyme Q10 in patients with type 1 or type 2 diabetes. However, some research suggests a possible benefit on insulin resistance. Details: Although a recent meta-analysis and some individual clinical research shows that coenzyme Q10 modestly reduces fasting glucose levels and glycated hemoglobin (HbA1c) in patients with type 1 or type 2 diabetes, most clinical research shows that coenzyme Q10 has no clinically meaningful effect on these parameters (456,492,2126,9890,96544,97911,97918,99636,11877,17704,44023,103778,109389). However, a recent meta-analysis in patients with type 1 or type 2 diabetes shows that improvements in insulin resistance may be clinically meaningful when compared with placebo (109389). In people with type 2 diabetes and nephropathy requiring hemodialysis, coenzyme Q10 120 mg orally daily for 12 weeks does not improve blood glucose levels, HbA1c, or lipid levels when compared with placebo, although it is associated with a decrease in serum insulin levels and insulin resistance (99636).
Parkinson disease. Most clinical research does not show any benefit with the use of oral coenzyme Q10 in patients with Parkinson disease. Details: While some conflicting evidence exists (8938,15255), a large clinical trial and a meta-analysis of 8 small clinical studies in patients with Parkinson disease show that taking coenzyme Q10 300-2400 mg daily for up to 2 years does not improve Parkinson disease symptoms at any stage of the disease, or slow progression of the disease, when compared with placebo (89421,95610). In addition, a clinical study in patients with mid-stage Parkinson disease shows that taking a specific nanoparticulate coenzyme Q10 supplement (Nanoquinon, MSE Pharmazeutilka) 100 mg orally three times daily does not reduce symptoms when compared with placebo (15395).
Post-polio syndrome. Muscle function in people with post-polio syndrome is not improved by oral coenzyme Q10. Details: Clinical research shows that taking coenzyme Q10 100 mg twice daily for 12 weeks does not improve muscle strength when compared with baseline, nor does it improve muscle function or muscle endurance when compared with placebo, in patients with post-polio syndrome (44054). Other clinical research shows that taking coenzyme Q10 100 mg daily for 60 days does not improve levels of fatigue when compared with placebo in patients with post-polio syndrome (97917).

LIKELY INEFFECTIVE

Athletic performance. There is some evidence that exercise can deplete coenzyme Q10 and that supplementation will prevent this depletion. However, there is no evidence that taking coenzyme Q10 is beneficial. Details: Clinical research shows that taking coenzyme Q10 orally does not improve aerobic or anaerobic power or perceived exertion in athletes and non-athletes (2109,2110,8911,44122,44227). While some evidence suggests coenzyme Q10 slightly improves tolerance to higher workloads, more research is needed to tell if coenzyme Q10 is effective for this purpose (8911). One clinical study shows that taking coenzyme Q10 300 mg orally daily for 8 days reduces exercise-induced fatigue when compared with placebo (44006); other research shows that doses of 100-200 mg do not have this effect (44122,44233,44299). Taking the ubiquinol form of coenzyme Q10 200 mg orally daily for one month prevents exercise-induced coenzyme Q10 depletion and decreases levels of reactive oxygen species in blood mononuclear cells in young male athletes performing an intense long-distance run. However, it does not affect physical performance or markers of muscle damage (99429).
Huntington disease. The ubiquinol form of coenzyme Q10 does not seem to improve function in people with this condition. Details: Ubiquinol, a reduced form of coenzyme Q10, has been evaluated for use in Huntington disease (11873). However, a large, high-quality study shows that taking coenzyme Q10 2.4 grams orally daily for up to 5 years does not slow the progression or functional decline in patients with Huntington disease (96538). Other studies using doses up to 600 mg daily also show no benefit (1357,8940).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Age-related macular degeneration (AMD). Oral coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in adults with early AMD shows that taking a specific combination product (Phototrop, Sigma-tau Health Science Ltd.) containing coenzyme Q10 10 mg, acetyl-L-carnitine 100 mg, and omega-3 fatty acids 530 mg orally daily for 12 months seems to reduce the percentage of patients who experience deterioration of vision by about 50%, and the percentage who have reduced light sensitivity by about 39%, when compared with placebo (43946). The effects of coenzyme Q10 alone are unclear.
Aging. Although there has been interest in using oral coenzyme Q10 for aging, there is insufficient reliable information about the clinical effects of coenzyme Q10 for this purpose.
Angina. There is some limited clinical evidence that coenzyme Q10 can improve exercise tolerance and symptoms in people with this condition. Details: Preliminary clinical research shows that taking coenzyme Q10 50 mg three times daily orally for 4 weeks improves exercise tolerance in people with angina by about 18% (2121). Also, taking 60 mg once daily for 4 weeks improves heart failure scores, angina symptoms, and heart volume when compared to baseline in patients with stable angina (44336). The validity of these findings is limited by the lack of a comparator group.
Anthracycline cardiotoxicity. Evidence on the use of coenzyme Q10 to protect against anthracycline cardiotoxicity in adults and children is conflicting. Details: Preliminary clinical research in children aged 3-12 years shows that taking coenzyme Q10 orally 100 mg twice daily might protect against anthracycline cardiotoxicity (44279). However, evidence from larger clinical trials evaluating patients aged 16-77 years is conflicting. Results from one of these studies suggests that intravenous administration of coenzyme Q10 1 mg/kg daily the day before, the day of, and for 2 days after anthracycline treatment does not protect against cardiotoxicity (44267). Differences between the studies may be due to methodological problems, or differences in doses, route of administration, and age of participants.
Asthma. Oral coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a combination of coenzyme Q10 (Q-Gel, Tishcon Corporation) 120 mg, vitamin E 400 mg, and vitamin C 250 mg orally daily in addition to conventional anti-asthmatic therapy for 16 weeks might reduce the dosage of corticosteroids required by patients with mild to moderate asthma. However, it does not appear to improve lung function any more than standard therapy alone (43969).
Attention deficit-hyperactivity disorder (ADHD). It is unclear if oral coenzyme Q10 is beneficial in children with ADHD. Details: A small clinical study in children aged 6-16 years with ADHD who are unresponsive to atomoxetine therapy shows that taking coenzyme Q10 1-3 mg/kg with atomoxetine 0.5-1.8 mg/kg daily for 6 months improves parent-rated symptoms of ADHD, particularly hyperactivity-related symptoms, when compared with placebo plus atomoxetine (107449).
Autism spectrum disorder. It is unclear if the ubiquinol form of coenzyme Q10 taken orally is beneficial in children aged 3-6 years with this condition. Details: A small clinical study in children aged 3-6 years suggests that taking the reduced form of coenzyme Q10, ubiquinol (Li-QH, Tishcon Corporation), 50 mg orally once daily for one week followed by 50 mg twice daily for 11 weeks, improves symptoms of autism spectrum disorder, including communication with parents, ability to play with friends, verbal communication, sleeping, food rejection, aggressiveness, and self-harm, when compared with baseline, per parent assessment (89419). The validity of these findings is limited by the small study size, the use of parent assessment, and the lack of a comparator group.
Bipolar disorder. It is unclear if oral coenzyme Q10 is beneficial for bipolar disorder in older adults. Details: Preliminary clinical research in people 55 years of age or older with bipolar disorder shows that taking coenzyme Q10 800 mg orally daily for 4 weeks improves symptoms of depression when compared with baseline (95606). The validity of this finding is limited by the lack of a comparator group.
Breast cancer. Low coenzyme Q10 levels may be associated with an increased risk of breast cancer. The benefit of coenzyme Q10 supplementation is unclear. Details: Population research in Chinese women has found that low plasma coenzyme Q10 levels are associated with an increased risk of breast cancer (44194).
Cancer. Low coenzyme Q10 levels may increase the risk of cancer development and progression. Details: Population research has found that low coenzyme Q10 levels are associated with increased risk of metastatic melanoma (43959). Preliminary clinical research suggests that taking coenzyme Q10 150 mg twice daily along with vitamins A, C, and E, selenomethionine, beta-carotene, and folic acid extends survival time by 40% when compared with predicted survival in patients with end-stage cancer from various different primary sites (44159). It is unclear if this effect is due to coenzyme Q10, other ingredients, or the combination.
Cardiovascular disease (CVD). It is unclear whether oral coenzyme Q10 has a role in preventing complications from CVD. Details: Preliminary clinical research shows that taking coenzyme Q10 300 mg 2 hours prior to an elective percutaneous coronary intervention does not reduce periprocedural myocardial injury or prevent major adverse cardiac events during one month of follow-up (96543). Other clinical research shows that taking a combination of coenzyme Q10 (Bio-Quinon, Pharma Nord) 100 mg twice daily plus organic selenium yeast tablets (SelenoPrecise, Pharma Nord) 200 mcg daily for 4-5 years reduces the risk of death from CVD by 7% when compared with placebo in elderly people living in Sweden (92904). This benefit appears to persist even after supplement discontinuation, with an 18% reduction at 10 years and an 11% reduction at 12 years (96546,97466,97906). In this same trial, post-hoc subgroup analyses in patients with elevated baseline D-dimer levels and/or hypertension or ischemic heart disease shows that taking this combination reduces cardiovascular mortality when compared with placebo (105874). It is unclear if these benefits are due to coenzyme Q10, selenium, or the combination.
Cataracts. It is unclear if coenzyme Q10-containing eye drops are beneficial in patients undergoing cataract surgery. Details: Clinical research suggests that administering an ophthalmic solution containing coenzyme Q10 and vitamin E D-alpha-tocopheryl polyethylene glycol 1000 succinate twice daily for 9 months increases the speed of nerve regeneration when compared with saline solution in post-cataract surgery patients (44228).
Cerebellar ataxia. It is unclear if coenzyme Q10 is beneficial for this condition. Details: Preliminary clinical research in patients with cerebellar ataxia shows that coenzyme Q10 30 mg/kg daily for 2 years improves ataxia scores by 48%, posture scores by 63%, and kinetic function scores by 37% when compared with baseline, but only in patients who are coenzyme Q10 deficient (44177). The validity of these findings is limited by the lack of a comparator group.
Chronic fatigue syndrome (CFS). Oral coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with CFS shows that taking coenzyme Q10 200 mg plus NADH 20 mg daily for 8 weeks does not improve measures of fatigue, sleep, or quality of life when compared with placebo (107448).
Chronic obstructive pulmonary disease (COPD). It is unclear if coenzyme Q10 is beneficial for improving exercise tolerance in people with COPD. Details: Preliminary clinical research suggests that taking coenzyme Q10 90 mg daily for 8 weeks reduces lactate production during anaerobic exercise in people with COPD, but does not improve oxygen consumption or exercise performance, when compared with baseline (44293). The validity of these findings is limited by the lack of a comparator group.
Cocaine dependence. Oral coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study in patients with cocaine dependence shows that taking a combination of coenzyme Q10 200 mg and L-carnitine 500 mg orally daily for 8 weeks does not reduce cocaine use when compared with placebo, as measured by urine benzoylecgonine levels and self-reported usage (43940).
Coronavirus disease 2019 (COVID-19). It is unclear if oral coenzyme Q10 is beneficial for patients with persistent symptoms after COVID-19 infection. Details: Clinical research in individuals with previous confirmed COVID-19 infection and continued symptoms lasting more than 12 weeks shows that taking coenzyme Q10 (Pharma Nord) 100 mg five times daily for 6 weeks does not reduce the number or severity of symptoms when compared with placebo. The most common symptoms were concentration problems, mental and physical fatigue, headache, and/or muscle weakness (109392).
Critical illness (trauma). It is unclear if oral coenzyme Q10 is beneficial in patients hospitalized due to acute trauma. Details: Preliminary clinical research in patients who are mechanically ventilated due to acute trauma and have low baseline coenzyme Q10 plasma levels shows that taking sublingual coenzyme Q10 (Nutri Q10, Nutri Century) 400 mg daily for 7 days reduces the duration of intensive care stay, mechanical ventilation, and hospitalization by 4 days, 2 days, and 6 days, respectively, when compared with placebo. Patients taking coenzyme Q10 also demonstrated larger improvements in organ function scores and coma scores than those taking placebo (105875).
Cyclic vomiting syndrome (CVS). Limited evidence suggests oral coenzyme Q10 may reduce episodes of CVS. Details: Preliminary clinical research shows that taking coenzyme Q10 10 mg/kg orally twice daily is comparable to amitriptyline 0.5-1 mg/kg/day for reducing the number of CVS episodes in both children and adults (17703).
Diabetic nephropathy. Although there has been interest in using oral coenzyme Q10 for diabetic nephropathy, there is insufficient reliable information about the clinical effects of coenzyme Q10 for this purpose.
Dilated cardiomyopathy. Very small clinical studies suggest that children and adolescents with dilated cardiomyopathy may benefit from oral coenzyme Q10. Details: Preliminary clinical research in children with dilated cardiomyopathy suggests that taking coenzyme Q10 3-10 mg/kg daily, divided into 2-3 doses for up to 9 months, improves ejection fraction and New York Heart Association (NYHA) classification when compared to baseline (12199,13223). Also, in people under 20 years of age, taking a specific oral liquid formulation of coenzyme Q10 (QuinoMit Q10 Fluid, MSE Pharmazeutika GmbH), 10 mg/kg daily for 24 weeks produces a small increase in ejection fraction and improves NYHA class from II to I in 30% of patients (99427). The validity of these findings is limited by the lack of comparator groups.
Dry eye. Ophthalmic coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research has evaluated the use of a specific eye drop (VisuXL, Visufarma) containing coenzyme Q10 and cross-linked hyaluronic acid, in a 1:1 ratio with alpha-tocopherol polyethylene glycol succinate. One study in menopausal women receiving antidepressants shows that placing 1 drop in each eye twice daily for 8 weeks reduces dry eye severity by 17% and improves tear break-up time when compared to 5 drops daily of carmellose eye drops (104553). In addition, another study in adults with mild to moderate dry eye shows that placing 1 drop in each eye four times daily for 12 weeks reduces dry eye severity by 14% and decreases some laboratory markers of dry eye when compared to hyaluronic acid alone. Both groups demonstrated similar improvement in meibomian gland function and tear break-up time (97909). The effect of coenzyme Q10 when used alone is unclear.
Dry mouth. It is unclear if oral ubiquinol or ubiquinone improves salivary secretion. Details: Preliminary clinical research suggests that taking coenzyme Q10, as the reduced ubiquinol form or as the oxidized ubiquinone form, 100 mg orally daily for one month, improves salivary secretion by 72% to 82% when compared with baseline in patients with dry mouth (44191). The validity of these findings is limited by the lack of a comparator group.
Erectile dysfunction (ED). It is unclear if oral coenzyme Q10 is beneficial in patients with ED. Details: A small, open-label study in patients with hypertension and complaints of ED shows that taking coenzyme Q10 200 mg daily for 3 months along with current antihypertensive therapy does not improve symptoms of ED when compared with antihypertensive therapy alone (107447).
Fatigue. It is unclear if oral coenzyme Q10 is beneficial for reducing fatigue. Details: A meta-analysis of low- to moderate-quality clinical research in mixed populations shows that taking coenzyme Q10 modestly reduces feelings of fatigue when compared with placebo. This improvement was consistent between groups of healthy individuals and individuals with fatigue related to disease. However, a sub-group analysis shows that benefits are limited to studies in which coenzyme Q10 was studied as a single ingredient. Doses of coenzyme Q10 ranged from 60 mg to 500 mg daily for 4-12 weeks with treatment effects appearing to be both dose- and duration-dependent (109387).
Friedreich ataxia. Oral coenzyme Q10 has been evaluated in combination with vitamin E; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking coenzyme Q10 (Bio-Quinon Q10, Pharma Nord) 200 mg orally twice daily plus vitamin E (Bio-E-Vitamin, Pharma Nord) 1050 IU twice daily for 47 months improves measures of cardiovascular function by 20% when compared with baseline. However, it does not improve posture or gait, or prevent deterioration of posture, gait, speech, or eye function, when compared with baseline (43943,44064). It is unclear if these benefits are due to coenzyme Q10, vitamin E, or the combination. Also, the validity of these findings is limited by the lack of a comparator group.
Hearing loss. There is conflicting evidence regarding the effects of oral coenzyme Q10 on hearing loss of various etiologies. Details: Some clinical research shows that taking coenzyme Q10 terclatrate (Qter), a water-soluble formulation of coenzyme Q10, 160 mg orally daily for 30 days improves hearing thresholds when compared to baseline in patients with age-related hearing loss (44171,44184). However, taking coenzyme Q10 terclatrate 200 mg daily for 7 days does not significantly improve hearing thresholds when compared with placebo in patients with noise-induced hearing loss (44143). Also, combining coenzyme Q10 with conventional steroid therapy for 2 weeks does not improve hearing when compared with steroid therapy alone in patients with sudden sensorineural hearing loss (44185).
Hepatitis C. It is unclear if oral coenzyme Q10 is beneficial in patients with this condition. Details: Clinical research shows that taking coenzyme Q10 up to 80 mg orally daily for 28 days does not reduce serum liver enzymes when compared with placebo in patients with chronic hepatitis C who are unresponsive to conventional treatment (44172).
Hyperlipidemia. There is conflicting evidence regarding the effects of coenzyme Q10 on cholesterol levels in adults. However, any changes are unlikely to be clinically meaningful. Details: A meta-analysis of 50 moderate-quality clinical trials shows that taking coenzyme Q10 has small beneficial effects on levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides when compared with a control, usually placebo (109394). However, whether coenzyme Q10 produces clinically meaningful changes is unclear. In a subgroup of patients with dyslipidemia, coenzyme Q10 does not seem to have significant beneficial effects on total cholesterol (109394). Also, previous individual clinical trials and meta-analyses in specific populations, including studies in which lipoprotein A was measured, as well as populations with diabetes, coronary artery disease, and others, have not shown beneficial effects on plasma lipids (17704,44187,96545,97918,109394). The effect of coenzyme Q10 on lipoprotein A has also been investigated. Individual studies and a meta-analysis show that taking coenzyme Q10 slightly reduces plasma levels of lipoprotein A when compared with placebo (17704,44187,96545). Most studies have used doses of 100-500 mg daily for 4-24 weeks (17704,44187,96545,96547,97910,109394). Coenzyme Q10 has also been studied in combination with other ingredients. A moderate-sized, open-label clinical study in adults with mild hypercholesterolemia and low cardiovascular disease risk shows that taking a combination product containing coenzyme Q10 2 mg, red yeast rice, grape seed extract, olive tree leaf extract, and B vitamins (Arichol, Epsilon Health) daily for 8 weeks reduces total cholesterol and LDL cholesterol, but not HDL cholesterol or triglycerides, when compared with placebo (111559). The validity of this effect is limited by a lack of blinding. It is unclear if this effect is due to coenzyme Q10, other ingredients, or the combination.
Hypertension. Most research suggests that oral coenzyme Q10 may reduce systolic blood pressure (SBP), but not diastolic blood pressure (DBP). Details: Most clinical research shows that taking coenzyme Q10 100-900 mg orally daily in divided doses, either alone or with conventional medications, for up to 12 weeks significantly lowers SBP (2122,3365,9890,17702,17650,17651,44343,109393). One meta-analysis of moderate quality clinical research in patients with cardiometabolic disorders shows that supplementation with coenzyme Q10, especially 100-200 mg daily for at least 12 weeks, reduces SBP by 5 mmHg (109393). However, some studies show conflicting results. Most clinical research shows that coenzyme Q10 supplementation does not reduce DBP (8907,96541,109393). Also, a meta-analysis of two clinical studies (17651,44211) shows that taking coenzyme Q10 100-200 mg orally daily has no significant effect on blood pressure when compared with placebo (95607). Conflicting results may be due to differences in the severity of hypertension at baseline, adjustments made to conventional medications during studies, and the presence of a variety of concomitant conditions. Some data also suggest that effects may be greater in people with low baseline levels of coenzyme Q10 (2122,17650,17651).
Hypertrophic cardiomyopathy. It is unclear if oral coenzyme Q10 is beneficial for this condition. Details: A very small clinical study of 7 patients suggests that taking coenzyme Q10 (Vitaline) 120-240 mg orally daily with the goal of raising blood levels above 2 mcg/mL, might improve symptoms of hypertrophic cardiomyopathy, including dyspnea and fatigue, and decrease cardiac wall thickness, when compared to baseline (11031). The validity of these findings is limited by the small size of the study and the lack of a comparator group.
Infertility. It is unclear if oral coenzyme Q10 helps women undergoing assisted reproductive technology (ART) treatment. Details: A meta-analysis of 5 small clinical studies in infertile women undergoing ART treatment shows that although coenzyme Q10 increases the odds of clinical pregnancy more than 2-fold, it does not seem to affect the rate of live births or miscarriages when compared with placebo or no treatment (103780).
Kidney failure. Oral coenzyme Q10 has been reported to improve renal function in people with kidney failure, but not in those with less severe kidney disease. Details: Preliminary clinical research in patients with kidney failure shows that taking coenzyme Q10 180 mg orally daily for 28 days improves blood urea nitrogen, serum creatinine, and creatinine clearance when compared with placebo (44347). However, other clinical research in patients with less severe kidney disease shows that taking coenzyme Q10 200 mg daily for 8 weeks does not significantly improve kidney function parameters, including urinary albumin, total protein, or glomerular filtration rate, when compared with placebo (44128).
Lichen planus. It is unclear if topical coenzyme Q10 is beneficial for oral lichen planus. Oral coenzyme Q10 has not been studied for this condition. Details: A small clinical study in patients with oral lichen planus conducted in Egypt shows that applying topical coenzyme Q10 (ubiquinol) 120 mg as a mucoadhesive tablet 3 times daily for 4 weeks does not improve pain scores or lesion size when compared with topical corticosteroid paste (111617).
Male Infertility. Oral coenzyme Q10 may improve some measures of sperm function in males with infertility, but there is no convincing evidence that it can increase pregnancy rates. Details: One small clinical study in males with idiopathic asthenozoospermia shows that coenzyme Q10 200 mg orally daily for 6 months improves sperm motility when compared with baseline (12169). The validity of this finding is limited by the lack of a comparator group. Coenzyme Q10 has also been studied in males with idiopathic oligoasthenoteratozoospermia, but results are conflicting. Studies have used coenzyme Q10 or its reduced form, ubiquinol, in doses of 200-300 mg orally daily for 26 weeks. Sperm density and motility are increased when compared with placebo, but pregnancy rates do not seem to improve (17413,89422). Three studies have used coenzyme Q10 200-400 mg orally daily for 12-26 weeks, with two reporting increased sperm concentration and motility when compared to baseline, but the other finding no improvements when compared with placebo (44190,102008,107444). Coenzyme Q10 has also been investigated in combination with other ingredients. In one preliminary clinical trial, taking coenzyme Q10 10 mg and vitamin E 100 mg three times daily for 3 months modestly increases levels of testosterone and improves progressive sperm motility and morphology when compared with baseline. However, taking an L-carnitine nutrient complex 15 grams twice daily was more effective for increasing testosterone and for improving sperm parameters (109390). Other small and preliminary clinical studies have investigated the effects of a specific combination product providing coenzyme Q10 20 mg twice daily for 6 months, along with acetyl-L-carnitine, L-carnitine, selenium, zinc, vitamin C, folic acid, vitamin B12, and citric acid (Proxeed Plus). Taking this combination product has been shown to improve measures of sperm quality such as sperm count, sperm concentration, total motility, and progressive motility when compared to baseline. The effect on sperm volume and morphology is unclear. Most research has been conducted in patients with oligoasthenozoospermia, although some benefit has also been shown in patients with varicocele-related infertility, especially those with more severe varicocele (102017,107395,111296). The validity of these findings is limited by the lack of comparator group. Also, it is unclear if these effects are due to coenzyme Q10, other ingredients, or the combination.
Maternally inherited diabetes mellitus and deafness (MIDD). It is unclear if oral coenzyme Q10 is beneficial for MIDD. Details: One small clinical study shows that taking coenzyme Q10 150 mg orally daily for 3 years might prevent progressive insulin secretory defect, exercise intolerance, and hearing loss when compared with baseline in people with this rare form of diabetes (2125).
Metabolic syndrome. It is unclear if oral coenzyme Q10 is beneficial in patients with metabolic syndrome. Details: A small clinical study in patients with metabolic syndrome receiving healthy dietary recommendations shows that taking coenzyme Q10 60 mg daily for 12 weeks does not have beneficial effects on blood glucose, cholesterol, waist circumference, or blood pressure when compared with placebo (109284).
Myocarditis. It is unclear if oral coenzyme Q10 is beneficial in patients with acute viral myocarditis. Details: A small observational study in Chinese patients with acute viral myocarditis has found that taking coenzyme Q10 10 mg and trimetazidine 20 mg three times daily for 2 weeks, along with standard care, is associated with higher rates of resolution and improved quality of life when compared with coenzyme Q10 plus standard care alone (107443). While coenzyme Q10 alone appeared to improve symptoms and markers of cardiac function when compared to baseline in some patients, the validity of these findings is limited by a lack of placebo control.
Nonalcoholic fatty liver disease (NAFLD). Coenzyme Q10 may reduce liver enzymes and the severity of NAFLD. Details: Preliminary clinical research in adults with NAFLD shows that taking coenzyme Q10 100 mg orally daily for 12 weeks reduces the clinical grade of NAFLD and decreases plasma levels of liver enzymes when compared with placebo (97907).
Obesity. Oral coenzyme Q10 does not seem to improve weight loss in adults. Details: A meta-analysis of small, highly heterogeneous clinical trials shows that taking coenzyme Q10 100-300 mg daily for up to 24 weeks does not reduce weight or body mass index when compared with placebo. However, the included studies were not designed to assess for weight loss and involved patients with type 2 diabetes, metabolic syndrome, kidney disease, liver disease, rheumatoid arthritis, and other conditions (105067).
Periodontitis. Data on the effects of oral or topical coenzyme Q10 are conflicting. It is unclear if coenzyme Q10 is beneficial for periodontitis. Details: Some very small, low-quality studies suggest that taking coenzyme Q10 orally, 50 mg daily for 3 weeks, might be beneficial for periodontitis (8917,8918). Preliminary research with topical coenzyme Q10 suggests it is ineffective (2107,2108). However, a meta-analysis of 11 clinical trials evaluating coenzyme Q10 topical gel shows reductions in plaque index, bleeding index, pocket index, clinical attachment level, and gingival index when compared with placebo gel or scaling and root planing alone. The greatest effects are seen when coenzyme Q10 gel is applied directly into the periodontal pocket daily for at least six weeks in combination with scaling and root planing (108958). The validity of these findings is limited by a high risk of bias and the overall low quality of the included studies. Coenzyme Q10 has also been studied in combination with other ingredients for periodontitis. A small clinical study in patients with moderate or advanced periodontitis shows that taking a supplement containing 30 mg of coenzyme Q10 in addition to alpha-lipoic acid, cranberry extract, grapeseed extract, selenium, vitamin C, vitamin E, and zinc twice daily for 8 weeks in addition to standard nonsurgical therapy does not improve periodontal indices including bleeding on probing, gingival recession, plaque index, or inflammation, among others, when compared with placebo (111708).
Physical performance. It is unclear if oral coenzyme Q10 improves physical performance in older adults with chronic kidney disease (CKD). Details: A small clinical study in mostly older adults with CKD shows that taking coenzyme Q10 1200 mg daily for 6 weeks does not improve measures of physical exercise endurance including aerobic capacity, total work, and work efficiency when compared with placebo (111558). The validity of these effects is limited by the small sample size and short study duration.
Polycystic ovary syndrome (PCOS). Most clinical studies suggest that oral coenzyme Q10 modestly improves symptoms in patients with PCOS. Details: A meta-analysis of clinical trials in patients with PCOS shows that taking coenzyme Q10 modestly improves measures of glycemic response, as well as plasma lipids and some sex hormones, when compared with placebo (109384). However, any changes are small and the clinical relevance is unclear. Also, although nine studies were included in the review, the number of studies included for each endpoint was much lower. Most clinical studies included in the analysis used 100-200 mg daily for 8-12 weeks (107446,109384). An additional small clinical study also shows that taking coenzyme Q10 (Nature Made) 100 mg orally daily for 12 weeks reduces fasting plasma glucose, insulin, and total cholesterol and improves insulin sensitivity when compared with placebo. This study also found that taking coenzyme Q10 reduces alopecia by about 33% and acne by 48% when compared with placebo (97914). Another small clinical study shows that taking coenzyme Q10 100 mg daily for 12 weeks reduces depression, anxiety, and hirsutism when compared with placebo (107446).
Prader-Willi syndrome (PWS). It is unclear if oral coenzyme Q10 is beneficial in patients with PWS. Details: Preliminary clinical research in children with Prader-Willi syndrome shows that taking coenzyme Q10 2.5 mg/kg orally daily for one year improves psychomotor development similarly to growth hormone therapy, although this might reflect natural changes in the condition occurring over time (44005).
Pre-eclampsia. Taking coenzyme Q10 orally seems to reduce the rate of pre-eclampsia in women at risk for the condition. Details: Clinical research shows that taking coenzyme Q10 (Q-absorb, Jarrow Formulas) 100 mg orally twice daily during pregnancy, starting at 20 weeks gestation and continuing until term, reduces the rate of pre-eclampsia by about 44% when compared with placebo in women at risk for developing this condition (17201).
Schizophrenia. It is unclear if oral coenzyme Q10 improves symptoms in patients with schizophrenia or schizoaffective disorder. Details: A small clinical study in patients with schizophrenia or schizoaffective disorder shows that taking coenzyme Q10 300 mg daily for 6 months does not improve attention, working memory, negative symptoms, mood disorders, or quality of life when compared with placebo (105069). This finding is limited by insufficient power and poor protocol adherence, with only 61% of the participants taking at least 90% of the study treatment.
Sepsis. There is no strong evidence that coenzyme Q10 is helpful in the management of sepsis or septic shock. Details: Patients with septic shock have been shown to have low levels of coenzyme Q10, but the effects of supplementation are unclear. Some preliminary clinical research shows that taking coenzyme Q10 100 mg orally twice daily for 7 days reduces the risk of in-hospital mortality by 69% and improves markers of inflammation, but does not reduce length of ICU stay, when compared with conventional treatment alone (102548). However, other preliminary research shows that taking coenzyme Q10 as ubiquinol 200 mg twice daily for 7 days has no effect on inflammatory or vascular endothelial biomarkers, mortality, or length of stay when compared with placebo (96540). Both studies were small and likely underpowered to detect a meaningful change in clinical outcomes.
Statin-induced myalgia. There is conflicting evidence regarding the effects of oral coenzyme Q10 on statin-associated muscular adverse effects, such as myalgia. Details: Some clinical research shows that taking coenzyme Q10 (Q-Sorb softgel, Nature's Bounty) 100 mg orally daily for 30 days reduces pain intensity when compared with baseline or vitamin E control in patients with statin-induced myalgia (16008,44345). Other clinical research shows that taking coenzyme Q10 (MGC Company) 50 mg orally twice daily for 30 days reduces muscle pain and pain interference with daily activities by 30% to 40% when compared with placebo (95604). One small study in adults with statin-induced myalgia shows that taking liquid coenzyme Q10 (Q-Factor, Giellepi S.p.A) 100 mg orally daily for 3 months modestly reduces pain scores, but not plasma creatine kinase (CK) levels, when compared with placebo (102007). Other clinical research shows that taking coenzyme Q10 (Bio-Quinon, Pharma Nord) 100 mg twice daily, with or without selenium, for 3 months, reduces muscle pain and weakness, cramps, and tiredness when compared with placebo (92909). However, not all studies have shown benefit. Meta-analyses of several small randomized controlled trials show that taking coenzyme Q10 100-600 mg daily for 1-3 months does not improve muscle pain, statin tolerability, or plasma CK activity in patients with statin-induced myalgia when compared with placebo (95602,103781,106050). However, the validity of these results is limited by small population size and high heterogeneity. Other clinical research shows that taking coenzyme Q10 60 mg twice daily for 3 months does not improve muscle pain when compared with placebo (44218). Also, taking coenzyme Q10 (Q-Gel, Tishcon Corporation) 200 mg daily for 12 weeks does not affect myalgia scores when compared with placebo in patients taking simvastatin (44346). Additionally, taking high doses of coenzyme Q10 600 mg daily for 8 weeks does not affect the incidence, severity, or time to onset of statin-induced myalgia when compared with placebo in patients taking simvastatin (95603). Reasons for these conflicting findings are not entirely clear. The inconsistent results do not appear to be related to the dose of coenzyme Q10 or plasma CK levels. About 50% of patients who experience statin-induced myalgia will tolerate a statin re-challenge with a lower or equivalent dose of the same or alternative statin after a statin-free interval, which is a higher response rate than seen in currently available studies with the use of coenzyme Q10. Taking coenzyme Q10 for 30 days may be a reasonable option if other attempts to improve tolerance have failed. If a significant improvement in pain related to statin use is not seen after 30 days of taking coenzyme Q10, it is unlikely to be beneficial (96548).
Statin-induced myopathy. There is conflicting evidence regarding the effects of coenzyme Q10 on statin-associated muscular adverse effects, including myopathy. Details: Clinical research shows that taking coenzyme Q10 (Bio-Quinon, Pharma Nord) 100 mg orally twice daily, with or without selenium, for 3 months, reduces muscle weakness and pain, cramps, and tiredness when compared with placebo in patients with statin-induced myopathy due to atorvastatin, fluvastatin, rosuvastatin, or simvastatin (92909). Preliminary clinical research also shows that taking coenzyme Q10 60 mg orally four times daily decreases the rate of dose-limiting statin-induced myopathy in patients taking high-dose lovastatin as an investigational treatment for cancer (11899,11900). However, when coenzyme Q10 (Myoquinon, Pharma Nord,) 400 mg orally daily is used in combination with selenium for 12 weeks, it does not affect atorvastatin-induced myopathy when compared with placebo (92908).
Toxin-induced liver damage. Oral coenzyme Q10 has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients being treated with anti-tuberculosis drugs shows that taking coenzyme Q10 200 mg, acetyl-L-carnitine 250 mg, and alpha-lipoic acid 250 mg twice daily for 2 weeks reduces the risk of drug-induced liver injury by 73% when compared with placebo (107445). It is unclear if these findings are due to coenzyme Q10, other ingredients, or the combination.
Ulcerative colitis. It is unclear if oral coenzyme Q10 is beneficial in patients with ulcerative colitis. Details: Preliminary clinical research in adults with ulcerative colitis shows that taking oral coenzyme Q10 (Nutri Q10, Nutri Century Company) 100 mg twice daily for 8 weeks modestly improves ulcerative colitis disease activity and quality of life scores when compared with placebo. Taking coenzyme Q10 also reduces systolic and diastolic blood pressure by 4 mmHg and 2 mmHg, respectively, when compared with placebo (106049). The clinical relevance of these changes is unclear.
Wrinkled skin. It is unclear if topical application of coenzyme Q10 cream can reduce wrinkles. Details: A small clinical study shows that applying a coenzyme Q10 1% cream to the skin twice daily for 5 months reduces objective wrinkle scores when compared to baseline (44082). The validity of this finding is limited by the lack of a comparator group. More evidence is needed to rate coenzyme Q10 for these uses.

OLIVE (organic virgin Olive Oil, Olive leaf extract)

INSUFFICIENT RELIABLE EVIDENCE to RATE

Dyspepsia. Oral olive leaf extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small study in healthy adults shows that taking a specific combination product containing olive leaf extract 24% and prickly pear cactus 33% (Mucosave, Bionap S.R.L.) 400 mg daily for 8 weeks seems to improve dyspepsia and other gastrointestinal symptoms when compared with placebo (105904). It is unclear if this benefit would occur in patients with clinically diagnosed dyspepsia.
Exercise-induced respiratory infections. It is unclear if oral olive leaf extract is beneficial for reducing respiratory infections from exercise. Details: A small clinical study in high school athletes shows that taking one tablet of olive leaf extract providing eleuropein 100 mg daily for 2 months during training season does not reduce the incidence of the common cold when compared with placebo. While it may reduce the number of sick days by 28%, a sub-group analysis suggests that this reduction is only evident in female athletes (101860).
Gastroesophageal reflux disease (GERD). Although there is interest in using oral olive leaf for GERD, there is insufficient reliable information about the clinical effects of olive for this condition.
Herpes zoster (shingles). Although there is interest in using oral olive leaf for shingles, there is insufficient reliable information about the clinical effects of olive for this condition.
Influenza. Although there is interest in using oral olive leaf for influenza, there is insufficient reliable information about the clinical effects of olive for this condition.
Metabolic syndrome. It is unclear if oral olive leaf extract is beneficial for improving body composition and cardiovascular risk factors in patients with metabolic syndrome. Details: A small clinical trial in overweight, middle-aged males at risk for metabolic syndrome shows that taking four capsules of olive leaf extract providing oleuropein 51.1 mg and hydroxytyrosol 9.7 mg daily for 12 weeks improves insulin sensitivity by 15% when compared with placebo. However, body composition, blood pressure, cholesterol levels, and other cardiovascular risk factors were not improved (92245).
Osteoarthritis. It is unclear if oral olive fruit or leaf extract is beneficial for improving osteoarthritis. Details: Preliminary clinical research shows that taking a freeze-dried aqueous extract of olive fruit 400 mg daily for 8 weeks decreases pain and increases mobility in people with osteoarthritis (14844). Other preliminary clinical research in adults with knee osteoarthritis shows that taking olive leaf extract 50.1 mg daily for 4 weeks improves overall pain measurements by 14%, compared to only 4% in the placebo group. However, many individual measurements of pain are not improved (92252).
Osteoporosis. It is unclear if oral olive leaf extract is beneficial for osteoporosis. Details: Clinical research shows that taking olive leaf extract (Bonolive, BioActor BV) 250 mg daily for 12 months, along with elemental calcium 400 mg daily, increases osteocalcin levels by about 32% when compared to baseline; this increase was significant when compared to those taking calcium 400 mg plus placebo, who showed a 6% decrease in osteocalcin levels. However, taking olive leaf extract does not significantly increase bone mineral density of the lumbar spine or femur neck when compared with placebo (92247).
Rheumatoid arthritis (RA). It is unclear if oral olive fruit extract is beneficial for improving RA symptoms. Details: Preliminary clinical research in adults with RA shows that taking an aqueous freeze-dried extract of olive fruit 400 mg daily for 8 weeks does not improve symptoms when compared with control (14844). More evidence is needed to rate the effectiveness of olive for these uses.

REISHI MUSHROOM (Reishi Mushroom extract)

POSSIBLY INEFFECTIVE

Hyperlipidemia. Preliminary clinical studies show that oral reishi mushroom does not improve lipid levels in patients with hyperlipidemia or type 2 diabetes. Details: Preliminary clinical research shows that taking reishi mushroom extract 1440 mg daily for 12 weeks does not significantly improve the lipid profile in patients with hyperlipidemia (70776). Also, a meta-analysis shows that taking reishi mushroom extract 1400-4000 mg daily for 12-16 weeks does not reduce total cholesterol or low-density lipoprotein (LDL) cholesterol in patients with type 2 diabetes (91435).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Aging. Although there has been interest in using oral reishi mushroom for aging, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Altitude sickness. Although there has been interest in using oral reishi mushroom for altitude sickness, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Alzheimer disease. A small clinical study suggests that oral reishi mushroom does not improve Alzheimer disease symptoms. Details: Preliminary clinical research in patients with Alzheimer disease shows that taking reishi mushroom powder 1000 mg three times daily for 6 weeks does not improve memory, language skills, or quality of life when compared with placebo (97942).
Asthma. Although there has been interest in using oral reishi mushroom for asthma, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Benign prostatic hyperplasia (BPH). Preliminary clinical research suggests that oral reishi mushroom extract can help reduce some lower urinary tract symptoms in patients with BPH. Details: Clinical research in patients with mild to moderate lower urinary tract symptoms (LUTS) associated with BPH, urinary incontinence, overactive bladder, or other conditions, shows that taking reishi mushroom extract 6 mg orally once daily for up to 12 weeks moderately improves total symptom severity measured on the International Prostate Symptom Score (IPSS) scale, when compared with placebo (91436,91437). A higher dose of 60 mg daily is not more effective than the 6 mg dose, and a lower dose of 0.6 mg daily is not more effective than placebo (91437). Reishi mushroom extract does not improve peak urine flow rate, residual urine volume, prostate volume, or quality of life when compared with placebo (91436,91437). The relevance of these results is unclear since not all of the patients with LUTS had BPH.
Bronchitis. Although there has been interest in using oral reishi mushroom for bronchitis, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Cancer. It is unclear if oral reishi mushroom is beneficial when used in conjunction with chemotherapy. Details: A meta-analysis of 9 clinical trials using various reishi mushroom products in combination with chemotherapy found that complete and partial responses increased by 30% with combination therapy when compared with chemotherapy alone. However, there was no difference in overall survival (102915). The reliability and applicability of these results are unclear since the trials looked at several different types of cancer, used varying doses and durations of therapy, and were all conducted in China or other Asian countries.
Cancer-related fatigue. It is unclear if oral reishi mushroom is beneficial in patients with breast cancer and fatigue. Details: Results from a small clinical study in breast cancer patients show that taking reishi mushroom powder 1000 mg orally three times daily for 4 weeks can improve cancer-related fatigue when compared with placebo (91438). However, it is not clear if the improvement is clinically meaningful.
Cardiovascular disease (CVD). It is unclear if oral reishi mushroom is beneficial for reducing CVD risk factors. Details: A meta-analysis of 5 low-quality studies in adults with diabetes shows that taking reishi mushroom 1400-3000 mg daily for 12-16 weeks does not reduce CVD risk factors, including total and low-density lipoprotein (LDL) cholesterol, triglycerides, blood pressure, and body mass index, when compared with placebo (91435).
Chronic fatigue syndrome (CFS). Although there has been interest in using oral reishi mushroom for CFS, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Chronic kidney disease (CKD). Although there has been interest in using oral reishi mushroom for CKD, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Colorectal adenoma. Limited clinical research suggests that oral reishi mushroom extract may be beneficial for reducing colorectal adenoma size. Details: Preliminary clinical research in patients with colorectal adenomas shows that taking reishi mushroom extract 1500 mg orally in two divided doses daily for 12 months reduces the number and size of adenomas when compared with no treatment (70774).
Coronary heart disease (CHD). It is unclear if oral reishi mushroom is beneficial for CHD. Details: Preliminary clinical research shows that taking a specific reishi mushroom extract (Ganopoly, Encore International Co.) 1800 mg orally three times daily for 12 weeks reduces symptoms of CHD, such as chest pain, palpitations, and shortness of breath, in a greater percentage of patients when compared with placebo (70800).
Diabetes. Evidence on the use of oral reishi mushroom in patients with type 2 diabetes is conflicting. Details: A meta-analysis of clinical research in patients with type 2 diabetes shows that taking reishi mushroom extract 1400-4000 mg daily for 12-16 weeks does not reduce glycated hemoglobin (HbA1c) or plasma lipids (91435). However, one preliminary clinical study in patients with type 2 diabetes shows that taking a specific reishi mushroom extract (Ganopoly, Encore International Co.) 1800 mg three times daily for 12 weeks reduces HbA1c, but not fasting blood glucose, when compared with placebo (70801).
Fibromyalgia. It is unclear if oral reishi mushroom is beneficial for fibromyalgia. Details: A small clinical trial in patients with fibromyalgia shows that taking reishi mushroom (MundoReishi Salud S.L.) powder 3 grams twice daily for 6 weeks does not improve mood, quality of life, anthropometric measures, blood pressure, or glycemic or lipid parameters when compared with placebo (108309,108310). However, the study may have been underpowered to detect any differences between groups.
Genital herpes. Oral reishi mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with recurrent genital herpes shows that taking 4.4 grams of a mixture of hot water extracts of reishi mushroom, terminalia, Job's tears, Wisteria floribunda, Trapa natans, and Elfvingia applanata orally once daily for 2 days, then 2.2 grams daily thereafter until outbreak resolution, decreases the time to outbreak resolution by 6 days when compared with previous outbreaks (91434).
Gulf war syndrome. It is unclear if oral reishi mushroom is beneficial for Gulf war syndrome. Details: A very small exploratory clinical trial in adults with Gulf war syndrome shows that taking reishi mushroom extract (JHS Natural Products, Mushroom Science) 1600 mg in two divided doses daily for 30 days does not improve symptoms when compared with placebo. Also, symptoms modestly worsened after an additional 30 days of treatment at a dose of 3200 mg daily (108311).
Hepatitis B. One small clinical study suggests that a specific reishi mushroom extract may reduce hepatitis B activity and improve liver function. Details: Preliminary clinical research shows that taking a specific reishi mushroom extract (Ganopoly, Encore International Co.) 1800 mg orally three times daily for 12 weeks reduces levels of hepatitis B viral DNA and hepatitis B surface antigen, which are markers of hepatitis B activity, and normalizes aminotransferase levels in a greater percentage of patients when compared with placebo (70799).
Herpes labialis (cold sores). Oral reishi mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with recurrent herpes labialis shows that taking 4.4 grams of a mixture of hot water extracts of reishi mushroom, terminalia, Job's tears, Wisteria floribunda, Trapa natans, and Elfvingia applanata orally once daily for 2 days, then 2.2 grams daily thereafter until outbreak resolution, decreases the time to outbreak resolution by almost 4 days when compared with previous outbreaks (91434).
Herpes zoster (shingles). Although there has been interest in using oral reishi mushroom for herpes zoster, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Human papillomavirus (HPV). Oral reishi mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with oral HPV shows that taking a combination of reishi and coriolus mushroom powders, 400 mg orally daily for 2 months, clears HPV in 88% of patients when compared with baseline (91433). The validity of this finding is limited by the lack of a comparator group.
Hypertension. Limited research suggests that oral reishi mushroom may be beneficial in some types of hypertension. Details: Preliminary clinical research shows that taking reishi mushroom extract 1440 mg daily for 12 weeks does not lower blood pressure in patients with hypertension (70776). However, in other clinical research, taking reishi mushroom extract 330-1440 mg daily for 1-6 months reduces blood pressure in patients with stage II or essential hypertension, but not in those with mild hypertension or diabetes (70786,70802,91435).
Influenza. Although there has been interest in using reishi mushroom for influenza, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Insomnia. Although there has been interest in using reishi mushroom for insomnia, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Lung cancer. Small clinical studies suggest that oral reishi mushroom does not reduce the size of lung tumors. Details: A meta-analysis of preliminary clinical research shows that taking reishi mushroom does not reduce the size of lung tumors. However, it may stimulate immune function and improve quality of life in lung cancer patients when compared with control (70779).
Peptic ulcers. Although there has been interest in using oral reishi mushroom for peptic ulcers, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose.
Rheumatoid arthritis (RA). Oral reishi mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients with active RA who are taking disease-modifying antirheumatic drugs shows that taking reishi mushroom extract 4 grams in combination with San Miao San (containing 2.4 grams each of atractylodes, phellodendron, and Achyranthes bidentata) daily for 24 weeks does not increase the percentage of patients achieving a 20% response based on the American College of Rheumatology (ACR) criteria or modify blood markers of disease and inflammation when compared with placebo (70767).
Stress. Although there has been interest in using oral reishi mushroom for stress, there is insufficient reliable information about the clinical effects of reishi mushroom for this purpose. More evidence is needed to rate reishi mushroom for these uses.

Safety view details

Below is general information about the safety of the known ingredients contained in the product Energize Cardiovascular Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

BLUE-GREEN ALGAE (organic Microalgae)

POSSIBLY SAFE ...when non-contaminated species of spirulina blue-green algae are used orally and appropriately (91713). The blue-green algae species Arthrospira platensis has been used with apparent safety in doses up to 19 grams daily for 2 months, or 10 grams daily for 6 months (18296,18300,18306,75944,91705,99703,104567,109965). The blue-green algae species Arthrospira fusiformis has been used with apparent safety in doses up to 4 grams daily for 3 months, or 1 gram daily for 12 months (15782,91717). Another blue-green algae species, Arthrospira maxima, has been used with apparent safety in a dose of 4.5 grams daily for up to 12 weeks (18297,99654,99655,102688). ...when non-contaminated, non-toxin producing strains of blue-green algae from the Aphanizomenon flos-aquae species are used orally and appropriately. Doses up to 1.6 grams daily have been used with apparent safety for up to 6 months (14842,18310). Some blue-green algae species can produce toxins called microcystins. According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549).

POSSIBLY UNSAFE ...when contaminated blue-green algae are used orally. Blue-green algae can be contaminated with heavy metals (including mercury, cadmium, lead, or arsenic), neurotoxins, and toxic microcystin-producing cyanobacteria such as Microcystis aeruginosa (9171,75966,91704,91711,96550). Microcystins are most commonly reported in the blue-green algae species Aphanizomenon flos-aquae harvested from Upper Klamath Lake in Oregon. The Oregon Department of Health has set a limit of 1 mcg of microcystin-LR equivalents per gram dry weight of blue-green algae, assuming consumption of about 2 grams/day by adults (91704,91713). However, many samples of Aphanizomenon flos-aquae have been reported to contain higher levels than this (9171,91704). According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549). When consumed orally, microcystins accumulate in the liver, binding to and inhibiting protein phosphatases, causing hepatocyte damage and possible tumor promotion (9171). Aphanizomenon flos-aquae can also produce neurotoxic compounds that may be present in supplements containing this organism (91704).

CHILDREN: POSSIBLY UNSAFE
when blue-green algae products are used orally. Blue-green algae can accumulate heavy metals such as lead and mercury (91704,91711). They can also contain toxic microcystins produced by contaminating species of cyanobacteria such a Microcystis aeruginosa (91704). Children are more sensitive to poisoning by microcystins (3536). The Oregon Department of Health has set a limit for microcystins of 1 mcg per gram dry weight of blue-green algae, but some countries have set very low exposure limits of 0.2 mcg per day and 0.8 mcg per day for infants and children, respectively (91704).

PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using. Some blue-green algae products, specifically those of the species Aphanizomenon flos-aquae, have been found to contain low amounts of beta-methylamino-L-alanine (BMAA). BMAA is associated with neurodegenerative diseases, and breast milk has been shown to be a potential source of BMAA exposure in infants (96550).

COCONUT OIL (organic virgin Coconut Oil)

LIKELY SAFE ...when used orally in food amounts. Coconut oil can be safely consumed as a component of the diet (12361,17935,94452,106494). However, coconut oil should not be considered a healthy alternative to other saturated fats (94453,94643). Coconut oil contains more saturated fat than animal based fats, including lard and butter (94643). Therefore, like all saturated fats, coconut oil should be used in moderation (94453,94643). ...when used topically and appropriately. Commercial products containing coconut oil in concentrations up to 100% have been used with apparent safety. However, most research has used commercial products with concentrations up to 70% (12356,17936,17941).

POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Taking coconut oil up to 10 mL orally two or three times daily for up to 12 weeks has been used with apparent safety in clinical research (17938,17942,90615,106493).

CHILDREN: POSSIBLY SAFE
when used topically and appropriately, short-term. Coconut oil has been used with apparent safety in children and neonates for about one month (13483,17937,90614,90616,96204,101873). There is insufficient reliable information available about the safety of coconut oil when taken orally in children.

PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of using coconut oil in medicinal amounts during pregnancy or lactation. Coconut oil ingestion increases the amount of lauric acid in breast milk within 10 hours. This indicates that fatty acids from coconut oil are rapidly transferred into human breast milk following oral intake (14086). The impact of this increase in lauric acid on nursing infants is not known.

COENZYME Q10 (Ubiquinol)

LIKELY SAFE ...when used orally and appropriately. Coenzyme Q10 has been used safely in studies lasting up to 5 years (2134,6037,6038,6407,8163,8938,8939,8940,15395,17413,17716,96538)(109391). ...when used topically on the gums (2107,2108,8916,8917,8918).

CHILDREN: POSSIBLY SAFE
when used orally and appropriately. Coenzyme Q10 in doses of 1-10 mg/kg/day has been used safely for up to 9 months under medical supervision (12199,13223,15256,44005,107449).

PREGNANCY: POSSIBLY SAFE
when used orally and appropriately. Coenzyme Q10 100 mg twice daily has been used with apparent safety during pregnancy, starting at 20 weeks gestation until term (17201).

LACTATION:
Insufficient reliable information available; avoid using.

OLIVE (organic virgin Olive Oil, Olive leaf extract)

LIKELY SAFE ...when olive fruit is used orally and appropriately in amounts commonly found in foods.

POSSIBLY SAFE ...when olive leaf extract is used orally and appropriately. Olive leaf extract providing 51-100 mg oleuropein daily has been used with apparent safety for 6-8 weeks (92245,92247,101860). There is insufficient reliable information available about the safety of olive fruit extract when used in amounts greater than those found in foods.

PREGNANCY AND LACTATION:
Insufficient reliable information available; stick with amounts commonly found in foods.

Interactions with Drugs view details

Below is general information about the interactions of the known ingredients contained in the product Energize Cardiovascular Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

BLUE-GREEN ALGAE (organic Microalgae)

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = D

Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.

Details

Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro (18311,18312,75892,92162,92163). However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time (97202).

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.

Details

Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs (18299). However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes (102689,109970). A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects (109970).

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.

Details

Blue-green algae have been shown to stimulate the immune system (2534,10267).

COENZYME Q10 (Ubiquinol)

ALKYLATING AGENTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Coenzyme Q10 has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals.

Details

Theoretically, antioxidants such as coenzyme Q10 might protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy (5158,5159). The clinical importance of this interaction is unknown.

ANTIHYPERTENSIVE DRUGS

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = B

Theoretically, coenzyme Q10 might have additive effects with antihypertensive drugs.

Details

Some clinical research shows that coenzyme Q10 can significantly lower blood pressure (2122,3365,8907,9890,17702,17650,17651,44343,96541), although other studies have shown conflicting results (17651,44211,95607).

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Coenzyme Q10 is chemically similar to menaquinone and might have vitamin K-like procoagulant effects, which could decrease the effects of warfarin.

Details

Concomitant use of coenzyme Q10 and warfarin might reduce the anticoagulant effects of warfarin (2128,6048,6199). Four cases of decreased warfarin efficacy thought to be due to coenzyme Q10 have been reported (2128,6048,11048). However, there is some preliminary clinical research that suggests coenzyme Q10 might not significantly decrease the effects of warfarin in patients who have a stable INR (11905).

REISHI MUSHROOM (Reishi Mushroom extract)

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.

Details

A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does (5476,13235).

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.

Details

Animal research suggests that reishi mushroom decreases blood sugar (70769). However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent (70801,91435).

ANTIHYPERTENSIVE DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.

Details

Reishi mushroom has shown hypotensive activity in animal research (5488,70784). Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension (70786,70802).

Report an Adverse Reaction to Energize Cardiovascular Support

Below is general information about the adverse effects of the known ingredients contained in the product Energize Cardiovascular Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

BLUE-GREEN ALGAE (organic Microalgae)

General ...Orally, spirulina blue-green algae seem to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.

Dermatologic ...Orally, a severe rash has been reported in a 49-year-old woman after taking a spirulina blue-green algae supplement (species and dose unknown). After stopping the supplement, inflammatory myopathy with muscle weakness and elevated creatine kinase occurred. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). In another case report, an 82 year-old woman developed a blistering skin condition over a 2-year period while taking spirulina blue-green algae (A. platensis, dose unknown). She had partly hemorrhagic bullae, secreting erosions and macerations. These symptoms resolved when the supplement was stopped and the patient was treated with oral prednisone, topical silver sulfadiazine, and topical triamcinolone / neomycin (75921).

Gastrointestinal ...Orally, gastrointestinal complaints are amongst the most common adverse effects associated with spirulina blue-green algae, including nausea, vomiting, diarrhea, and abdominal cramps (19272,75924,91713,109969). Similarly, common adverse effects associated with the blue-green algae species Aphanizomenon flos-aquae are stomach upset, flatulence, diarrhea, and bloating (14842).

Hematologic ...Orally, three cases of mild gum bleeding and one case of mild bruising have been reported in patients taking spirulina blue-green algae (Cyactiv, Cerule LLC) 2. 3 grams daily (containing approximately 1 gram of phycocanin) for 2 weeks (97202).

Hepatic ...Orally, significant elevations of liver function tests within 2 weeks of starting a spirulina blue-green algae supplement (species and dose unknown) have been reported in a 52-year-old man stabilized on amlodipine, simvastatin, and acarbose. A biopsy showed feathery degeneration and ballooning of hepatic cells. Cholestasis was present, and an ex-vivo lymphocyte stimulation test for spirulina blue-green algae was positive. All drugs and the spirulina blue-green algae supplement were stopped, with return of the LFTs to normal (9172).

Immunologic ...Orally, urticarial rashes and pruritus have occurred as part of generalized allergic reactions to blue-green algae (91706,91711,91712).
In one case report, a 14-year-old male experienced anaphylaxis with urticaria, lip edema, and asthma 6 hours after taking five tablets of spirulina blue-green algae (A. platensis, strength unknown). He had a positive skin prick test. Oral challenge to an extract of the tablets, and IgE from his serum, reacted with the beta chain of C-phycocyanin from A. platensis (91712).
In another case report, a 17-year-old male with a history of multiple allergies developed rash, pruritus, angioedema, wheezing, and dyspnea within 10 minutes of taking spirulina blue-green algae (A. platensis) 300 mg. He had a positive skin test to A. platensis but no other ingredients of the tablets (91706).

Musculoskeletal ...Orally, after a 49-year-old woman stopped taking a spirulina blue-green algae supplement (species and dose unknown), the patient experienced inflammatory myopathy with muscle weakness and elevated creatine kinase. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). Another case report describes acute rhabdomyolysis that occurred after consumption of spirulina (Arthrospira platensis, Hawaiian spirulina, Solgar Inc., Leonia, NJ) 3 grams daily for 1 month. The 24-year old man presented with weakness, myalgias, elevated creatine kinase and liver function tests, and myoglobinuria (75922).

COCONUT OIL (organic virgin Coconut Oil)

General ...Orally and topically, coconut oil is generally well tolerated.
Most Common Adverse Effects:
Orally: Increased cholesterol levels.
Serious Adverse Effects (Rare):
All routes of administration: Allergic reactions, including anaphylaxis, in sensitive individuals.

Cardiovascular ...Due to its high saturated fat content, there has been some speculation that consuming coconut oil might increase cholesterol levels and the risk of cardiovascular disease. Several population and clinical studies have found that consuming coconut oil increases total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol in some patients (12361,14407,17935,17940,94451,94452,99103,101877,101879,106489,106494). In patients with normal to high cholesterol levels, consuming a daily diet providing 30% to 36% of calories from fat, of which 46% to 66% is from coconut oil, for 4-12 weeks increases total cholesterol by about 12-15 mg/dL, low-density lipoprotein (LDL) cholesterol by about 9-12 mg/dL, and HDL cholesterol by 3-6 mg/dL when compared to a diet containing vegetable oils, especially those rich in polyunsaturated fatty acids (17935,94451,94452,101877,106489). In some cases, these cholesterol effects are similar to those seen in patients consuming a similar diet containing butter or beef fat (12361,17935,94451,99103,101879). Despite the potential effects of coconut oil on cholesterol levels, population research has not found an association with coconut oil consumption and risk of adverse cardiovascular events such as myocardial infarction or angina (14407,96205). Advise patients not to rely on coconut oil as a "healthy" alternative to other saturated fats.

Dermatologic ...In one case report, a 6-year-old child developed urticaria and hives from applying coconut oil to the skin. The child had been exposed to coconut oil consistently since 2 weeks of age, indicating sensitization over the course of regular exposure (95806). In clinical research, one patient reported localized pruritus immediately after applying a combination of coconut oil, anise oil, and ylang ylang (13483). It is unclear if this event was due to coconut oil, other ingredients, or the combination. Also, it is possible that this was an idiosyncratic event.

Gastrointestinal ...Orally, diarrhea and gastroenteritis have been reported rarely (101877).

Hepatic ...Orally, taking virgin coconut oil in the diet for 28 days modestly increased levels of liver enzymes in patients with coronavirus disease 2019 (COVID-19). However, it is unclear if this was due to the coconut oil or to the illness (107664).

Immunologic ...Several cases of allergic reactions have been reported for patients who consumed coconut fruit. In some of the cases, the patients were previously diagnosed with sensitivity to other tree nuts, including peanuts, so cross-sensitivity is suspected. In a separate case report, a 17-year-old male was found to be sensitized to both coconut and buckwheat, indicating a possible cross-sensitivity between the two allergens (95808). In other cases, the patients did not show sensitivity to any other allergens, so the patients were considered to have a single allergy to coconut fruit (12359,12360).
Because coconut oil is derived from coconut fruit, ingestion of coconut oil may theoretically cause allergic reactions in patients with confirmed allergy to coconut fruit. In one case report, a 6-year-old child who had previously experienced urticaria and hives from applying coconut oil to the skin experienced throat swelling and anaphylaxis after eating food containing coconut, indicating a sensitivity to both the fruit and the oil via both topical application and ingestion (95806). However, allergic reactions to coconut appear to occur significantly less often than allergies to other food items such as wheat, milk, soy, or peanut (14408).

COENZYME Q10 (Ubiquinol)

General ...Orally, coenzyme Q10 is generally well tolerated. In clinical studies, no serious adverse effects have been reported.
Most Common Adverse Effects:
Orally: Gastrointestinal side effects such as appetite suppression, diarrhea, epigastric discomfort, heartburn, nausea, and vomiting. These generally occur in less than 1% of patients. Some of these adverse effects can be minimized if daily doses above 100 mg are divided.

Cardiovascular ...Palpitations have been reported as being possibly associated with coenzyme Q10 treatment (89421). Death due to myocardial infarction occurred in one Parkinson disease patient taking coenzyme Q10; causality is unclear (15395).

Dermatologic ...Two of 143 participants in a case series reported skin itching after starting treatment with oral coenzyme Q10 (6047). Allergic rash has also been reported (6409,11872). An itching exanthema was seen in two heart failure patients treated with intravenous coenzyme Q10 (44284).

Gastrointestinal ...Gastrointestinal side effects of coenzyme Q10 have included nausea (3365,6409,8907,10152,43982,44172,44179,44330,89421,109392), vomiting (3365,10152,44330,89421), epigastric discomfort (3365,44179,44330,89421), constipation (109392), diarrhea (44179,92904,89421,109392), stomach upset (8940,12170,109387,109388,109392), loss of appetite (2121), heartburn (2121,44179,109392), and flatulence (43982), although this occurs in less than 1% of patients. In one clinical study, gastrointestinal bleeding in association with angiodysplasia has been reported to be possibly related to coenzyme Q10 treatment (89421).

Genitourinary ...An uncomplicated urinary infection was reported in a patient taking oral coenzyme Q10 (nanoQuinon, MSE Pharmazeutika) (44020).

Hematologic ...Thrombocytopenia was noted in one patient treated with oral coenzyme Q10 (44296); however, other factors (viral infection, other medications) may have been responsible for this adverse effect.

Musculoskeletal ...Increased plasma creatine kinase with high-intensity exercise has been reported in patients taking coenzyme Q10 (44303). Muscle pain has been reported rarely in one clinical trial (109392).

Neurologic/CNS ...Headache and dizziness have been reported in human research (3365,11872,43982,44330,109392). Insomnia has been reported as being possibly associated with coenzyme Q10 treatment (89421). Cognitive decline, depression, and sudden falls were reported rarely in a clinical trial of patients with Huntington disease (8940). Increased lethargy was reported for one patient treated with oral coenzyme Q10 (44042). Feeling of internal trembling has been reported in a clinical trial for one patient treated with coenzyme Q10 (44020).

Ocular/Otic ...Visual sensitivity to light has been reported for a patient treated with coenzyme Q10. However, the association of this effect with coenzyme Q10 treatment was not clear (6409).
A burning sensation has been reported for 10% of patients treated with a topical eye solution containing coenzyme Q10 and alpha-tocopheryl polyethylene glycol 1000 succinate following cataract surgery (44228).

Psychiatric ...Worsening depression has been reported as being possibly associated with oral coenzyme Q10 treatment (89421).

Pulmonary/Respiratory ...Drug-induced pneumonitis was diagnosed in a 61 year-old woman who had been taking coenzyme Q10 and perilla leaf extract for two months (43978). Symptoms improved after she stopped taking the supplements and began taking oral prednisone. Causation from coenzyme Q10 was unclear.

Other ...In a case report, a naval aviator using a supplement containing coenzyme Q10 and niacin had reduced G tolerance (44186). G tolerance was regained with cessation of the supplement.

OLIVE (organic virgin Olive Oil, Olive leaf extract)

General ...Orally, olive fruit is well tolerated when used in typical food amounts. Olive leaf extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Headache and stomach discomfort.

Dermatologic ...Orally, one patient in one clinical trial reported bad skin and acne after using olive leaf extract (101860).

Gastrointestinal ...Orally, three patients in one clinical trial reported stomach ache after using olive leaf extract (101860).

Neurologic/CNS ...Orally, three patients in one clinical trial reported headache after using olive leaf extract (101860).

Psychiatric ...In one case report, a 67-year-old female experienced irritability, anger, a lack of control, and feelings of sadness and negativity after consuming a multi-ingredient product containing olive leaf extract 5 grams, horseradish root, and eyebright daily for 38 days. All psychiatric symptoms disappeared within days of stopping the combined product. It is hypothesized that the hydroxytyrosol component of olive leaf extract contributed to these symptoms due to its chemical similarity to dopamine; however, it is not clear if these symptoms were due to the olive leaf extract or to the other ingredients (96245).

Pulmonary/Respiratory ...Olive tree pollen can cause seasonal respiratory allergy (1543).

REISHI MUSHROOM (Reishi Mushroom extract)

General ...Orally, reishi mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, dry mouth, itching, nausea, rash, and stomach upset.

Dermatologic ...Orally, reishi mushroom can cause itching, rash, and other skin reactions (12,5479).

Gastrointestinal ...Orally, reishi mushroom can cause dryness of the mouth, throat, or nasal cavity, nausea, stomach upset, and, more rarely, diarrhea (12,70779,91438,108309).

Hematologic ...Orally, reishi mushroom can cause nosebleed and bloody stools (12,91438).

Hepatic ...One case of hepatotoxicity and one case of fatal fulminant hepatitis have been reported in patients who had used reishi mushroom powder for 1-2 months (70766). There is a case report of a 61-year-old male with hypereosinophilia associated with hepatic nodules following the use of reishi mushroom powder for about 2 months. Symptoms resolved after discontinuation of the product. Although these side effects were thought to be associated with the use of reishi mushroom powder, it is unclear if other factors played a role. The patient had been taking tegafur, gimeracil, and oteracil potassium for about 4 months following anterior resection for rectal adenocarcinoma but discontinued these agents and initiated reishi mushroom due to liver injury (108312).

Neurologic/CNS ...Orally, reishi mushroom can cause dizziness (91438). Other rare symptoms include insomnia and headache (70776,70779).

Pulmonary/Respiratory ...Respiratory allergy to reishi spores can occur (12,5479). Sore throat and runny nose have also been reported (70776,91438).
