Liposomal Glutathione 700 mg [Discontinued] by NutriFlair

POSSIBLY EFFECTIVE

• Cisplatin-induced neurotoxicity. Intravenous glutathione seems to reduce neurotoxicity from cisplatin. Details: Clinical studies in cancer patients receiving cisplatin shows that administering glutathione 1.5 grams/m2 by intravenous injection over 15 minutes seems to help prevent neurotoxicity and other toxicities from cisplatin when compared with control. Glutathione may also increase the highest dose of cisplatin that patients are able to tolerate (5373,5374,5377,5378,5380). In one study, this same dose of intravenous glutathione was administered, along with intramuscular glutathione 600 mg on days 2-5 (5374).

• Aging. Although there is interest in using oral glutathione for aging, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Alcohol use disorder. Although there is interest in using oral glutathione for alcohol use disorder, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Athletic performance. Oral glutathione has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in young, resistance-trained males shows that taking glutathione (Setria, Kyowa Hakko Bio) 200 mg in combination with L-citrulline 2 grams daily for 8 weeks in conjunction with resistance training has no effect on muscle strength, as measured by leg and bench presses, when compared with L-citrulline alone or with placebo (97394). The trial shows the increase in lean body mass with training to be significantly higher with glutathione and L-citrulline compared with placebo at 4 weeks. However, by 8 weeks of training lean body mass is not different between supplementation and placebo. An additional small, cross-over trial in young, endurance-trained males shows that taking glutathione 200 mg in combination with L-citrulline 2 grams (Setria Performance Blend, Kyowa Hakko Bio) daily for 8 days does not improve high speed running performance, as measured by time to exhaustion, when compared with placebo (112285).
• Angioplasty. It is unclear if intravenous glutathione is beneficial in patients recovering from angioplasty following myocardial infarction. Details: A small clinical trial in Italian adults undergoing primary percutaneous coronary intervention (PCI) for recent ST-elevation myocardial infarction (STEMI) shows that intravenous infusion of glutathione sodium salt 2500 mg/25 mL over 10 minutes before angioplasty and at 24, 48 and 72 hours after angioplasty reduces length of hospital stay by around 2 days; reduces markers of oxidative stress, inflammation, and cardiomyocyte damage; and improves measures of left ventricular function at 6-month's follow-up when compared with placebo (111417,111418).
• Alzheimer disease. Although there is interest in using oral glutathione for Alzheimer disease, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cardiovascular disease (CVD). Although there is interest in using oral glutathione for preventing CVD, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cataracts. Although there is interest in using oral glutathione for cataracts, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral glutathione for CFS, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cirrhosis. It is unclear if oral glutathione is beneficial for improving cirrhosis severity. Details: A small clinical study in patients with cirrhosis shows that taking glutathione 500 mg daily with or without vitamin B6 50 mg daily for 12 weeks does not affect disease severity or reduce oxidative stress when compared with placebo (104392). These findings are limited because the study might not have been powered to detect a difference between groups, as 21 of the 61 participants were lost to follow-up.
• Cognitive function. Oral glutathione has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small cross-over trial in healthy adults shows that taking a product providing 20 mg/day of glutathione as part of a combination product containing probiotics (L. helveticus, Lactiplantibacillus plantarum, Bifidobacterium longum), inulin, zinc, potassium, magnesium and lactoferrin (Puraflor, GSK Consumer Healthcare) for 4 weeks does not affect cognitive performance during acute stress when compared with placebo (110923).
• Contrast induced nephropathy. It is unclear if intravenous glutathione is beneficial for preventing contrast induced nephropathy. Details: A small, non-blinded clinical study in patients aged 65 or older with diabetes undergoing percutaneous coronary intervention (PCI) shows that intravenous reduced glutathione 180 mg daily for 4 days, starting 6 hours prior to PCI, in conjunction with saline hydration, does not reduce the rate of contrast induced nephropathy when compared with saline hydration alone. Saline hydration was administered at a rate of 1 mL/kg/hr, starting 6 hours prior to PCI and continuing for 12 hours after PCI (107477). However, this study may have been inadequately powered to detect a difference between groups.
• Cystic fibrosis. It is unclear if oral glutathione is beneficial in children with this condition. Details: A small clinical study in children ages 2-10 years old with cystic fibrosis shows that taking glutathione powder 65 mg/kg daily in 3 divided doses for 6 months does not impact weight or inflammatory biomarkers when compared with placebo (104391).
• Glaucoma. Although there is interest in using oral glutathione for glaucoma, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Idiopathic interstitial pneumonia. Although there is interest in using inhaled glutathione for idiopathic pulmonary fibrosis, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral glutathione is beneficial in patients with NAFLD. Details: Preliminary clinical research shows that taking glutathione 300 mg daily for 4 months reduces alanine aminotransferase (ALT) levels by around 13% and triglyceride levels by around 16%, but has no impact on aspartate aminotransferase (AST) levels or liver stiffness, when compared with baseline in patients with NAFLD (97397). The validity of these findings is limited by the lack of a comparator group.
• Osteoarthritis. Although there is interest in using oral glutathione for osteoarthritis, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Parkinson disease. It is unclear if intranasal glutathione is beneficial for improving Parkinson disease symptoms. Details: A small clinical study in patients with Parkinson disease shows that taking glutathione intranasally 100-200 mg three times daily for 3 months has no effect on symptoms when compared with placebo (97398). More evidence is needed to rate glutathione for these uses.

LIKELY INEFFECTIVE

• Alzheimer disease. Lecithin does not improve daily functioning in patients with Alzheimer disease. Details: In patients with Alzheimer disease, taking various types of lecithin, 1.2-45 grams daily for up to 6 months, alone or in combination with various conventional medications, does not improve cognitive function or other measures of disease progression (5149,5151,5152,5156,14817,14823,14825,14837,14838).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related cognitive decline. It is unclear if oral lecithin can slow age-related cognitive decline. Details: A small clinical crossover study in healthy adults aged 64 years and older shows that taking lecithin 26 grams orally daily, alone or in combination with physostigmine, for 5 weeks does not seem to improve memory when compared with placebo (19204).
• Anxiety. Although there is interest in using oral lecithin for anxiety, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Atopic dermatitis (eczema). Although there is interest in using oral lecithin for atopic dermatitis, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Bipolar disorder. It is unclear if oral lecithin is beneficial in patients with bipolar disorder. Details: A clinical study in six patients with mania shows that taking lecithin 10 mg three times daily improves symptoms of delusions, incoherent speech, and hallucinations when compared with placebo (14839).
• Dry skin. Although there is interest in using topical lecithin for dry skin, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Friedreich ataxia. Small clinical studies suggest that oral lecithin is not beneficial in people with Friedreich ataxia. Details: Preliminary clinical research shows that taking lecithin 25 grams orally daily for 1 month does not have any benefit in people with Friedreich ataxia (59298). Other preliminary clinical research shows that taking lecithin for a longer period of 6 months also does not improve performance (19211).
• Hyperlipidemia. Although lecithin may lower cholesterol in healthy people, it does not seem to improve cholesterol levels in people with hyperlipidemia. Details: Some clinical research shows that taking lecithin 20-30 grams daily for up to 11 months decreases cholesterol in healthy people (5147,14820). However, other clinical research shows that lecithin has no effect on low-density lipoprotein cholesterol or total cholesterol levels in people with hyperlipidemia (5148,14820).
• Parkinson disease. It is unclear if oral lecithin is beneficial in patients with Parkinson disease. Details: Preliminary clinical research in patients with Parkinson disease shows that taking lecithin 32 grams daily for 8 weeks does not improve symptoms when compared with placebo (19212).
• Postoperative pain. It is unclear if oral lecithin is beneficial for reducing postoperative pain. Details: Preliminary clinical research shows that taking lecithin 20 grams prior to surgery increases choline levels, but does not reduce postoperative pain after gynecological surgery, when compared with placebo (91231).
• Tardive dyskinesia. It is unclear if oral lecithin is beneficial in patients with tardive dyskinesia. Details: Two small clinical studies in patients with tardive dyskinesia shows that taking lecithin orally for 2 months, alone or in combination with lithium, does not improve symptoms when compared with placebo (14822,14824).
• TPN-associated hepatic steatosis. It is unclear if oral lecithin is beneficial in patients with hepatic steatosis associated with long-term total parenteral nutrition (TPN). Details: A small clinical study in patients on long-term TPN with low choline levels suggests that taking lecithin 20 grams orally twice daily for 6 weeks reduces the degree of hepatic steatosis, compared with no significant changes in those taking placebo (5140).
• Ulcerative colitis. Oral lecithin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a disease-specific medical food (Profermin, Nordisk Rebalance) containing lecithin, fermented oats, barley malt, and lactobacillus plantarum, as 250 mL twice daily for 24 weeks, decreases disease activity by over 56% when compared with baseline and leads to remission in 46% of patients with mild-to-moderate ulcerative colitis (91228). Other preliminary clinical research in this population shows that taking Profermin 250 mL twice daily for 8 weeks improves disease activity and remission rate when compared with another medical food (Fresubin Original, Fresenius Kabi) (90271). The effects of lecithin alone are unclear. More evidence is needed to rate lecithin for these uses.

POSSIBLY EFFECTIVE

• Coronary heart disease (CHD). The U.S. Food and Drug Administration (FDA) allows a qualified health claim stating that using high-oleic acid sunflower oil as a replacement for other dietary fats and oils higher in saturated fat may reduce the risk of CHD. Details: A meta-analysis of clinical studies shows that replacing 7.5% of energy from partially hydrogenated vegetable oils with high-oleic acid sunflower oil can reduce CHD risk by about 9% to 19%. Furthermore, analysis of results from observational studies found that replacing partially hydrogenated oil with high-oleic acid sunflower oil is associated with a 16% to 35% reduction in the risk of CHD events (95745). The FDA allows for a qualified health claim that replacing dietary fats and oils higher in saturated fat with high-oleic acid sunflower oil may reduce the risk of CHD. To achieve this benefit, the use of high-oleic acid sunflower oil should not increase total daily energy intake. The suggested daily dietary intake is about 20 grams (1.5 tbsp) of high-oleic sunflower oil in place of other fats and oils (98563). Sunflower oil that contains high amounts of linoleic acid rather than oleic acid does not appear to improve cholesterol levels or reduce the risk of cardiovascular events in patients with CHD (96205).
• Hypercholesterolemia. Consuming sunflower oil in the diet may reduce low-density lipoprotein (LDL) cholesterol levels in some patients. Details: There is evidence that using sunflower oil in the diet as 45-50 grams daily for up to 12 weeks is more effective than olive oil for decreasing LDL cholesterol and apolipoprotein B levels in healthy individuals (9780). Also, clinical research in patients with mild hyperlipidemia or moderate hypercholesterolemia shows that consuming specific brands of mid-oleic acid (NuSun) or high-oleic acid (Sunola, Meadow Lea Foods) sunflower oils as 15% to 20% of dietary calories for up to 5 weeks is more effective than olive oil or saturated fat for decreasing total cholesterol, LDL cholesterol, and apolipoprotein B levels (76697,76698). Also, consuming a high-oleic sunflower oil-rich diet for 3 weeks decreases total cholesterol levels to a greater extent than diets enriched with palm oil or medium-chain triglycerides in patients with mild hypercholesterolemia (67569). Other preliminary clinical research in patients with moderate hypercholesterolemia shows that consuming a diet rich in sunflower oil for 3 weeks decreases total cholesterol and LDL cholesterol levels when compared with baseline. However, levels of high-density lipoprotein (HDL) cholesterol appear to be lowered as well (76714). Despite these beneficial effects, sunflower oil might be less effective than some other dietary oils. Taking sunflower oil for 3 months appears to be less effective than rice bran oil for lowering cholesterol in patients with hypercholesterolemia (76699). Also, while consuming sunflower oil 45 grams daily, as part of the diet and as a supplement, for 12 weeks reduces levels of total cholesterol and LDL cholesterol when compared to baseline, it appears to be less effective at reducing total cholesterol levels than flaxseed oil in certain patients at risk for atherosclerosis (76696). In addition, taking sunflower oil 15.1 grams daily for 4 months does not appear to reduce levels of total or LDL cholesterol in patients with peripheral vascular disease (76691).

POSSIBLY INEFFECTIVE

• Hypertension. Oral sunflower oil does not seem to lower blood pressure. Details: Preliminary clinical research in adults with hypertension shows that taking sunflower oil 30-40 grams daily for one year is less effective than extra-virgin olive oil for reducing blood pressure (5091). Also, clinical research in elderly adults with hypertension shows that taking 60 grams of sunflower oil daily for 4 weeks is less effective than virgin olive oil for reducing systolic blood pressure (76692).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Atherosclerosis. It is unclear if oral sunflower oil is beneficial for atherosclerosis; some clinical research suggests that it may provide less benefit than other dietary oils. Details: Some preliminary clinical research in individuals with overweight and obesity shows that taking sunflower oil 30 mL (about 27 grams) daily for 90 days decreases carotid intima-media thickness (CIMT) by 3.5% when compared to baseline, but not when compared with olive oil or flaxseed oil. Sunflower oil also improves flow-mediated vasodilation by 73% when compared to baseline, compared with no improvement in those taking flaxseed oil or olive oil (99303). Other preliminary clinical research in individuals waiting for carotid endarterectomy shows that taking sunflower oil 6 grams daily for up to 189 days is less effective than the same dose of fish oil, and equivalent to control oil, for improving the status of atherosclerotic plaques (76688).
• Atopic dermatitis (eczema). Although there is interest in using topical sunflower oil for atopic dermatitis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Child growth. It is unclear if topical sunflower oil is beneficial for early child growth. Details: A large preliminary clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, increases weight gain by 1.3 gram/kg daily when compared with a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. The increase in weight gain was highest for infants weighing less than 1500-2000 grams at birth (108141). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
• Dry mouth. It is unclear if rinsing the mouth with sunflower oil is beneficial for dry mouth. Details: Preliminary clinical research in adults with moderate dry mouth associated with medication use shows that using a sunflower oil mouth rinse and gargling for 5-8 minutes before spitting it out twice daily for 7 days improves dry mouth scores by 23% when compared to baseline. Sunflower oil also improves the ability to swallow and sleep with dry mouth, but not other dry mouth symptoms or saliva flow rate, when compared with control (105523). This study may have been inadequately powered to detect a difference between groups.
• Dry skin. It is unclear if topical sunflower oil is beneficial for dry skin in infants. Details: Preliminary clinical research in full-term, newborn infants shows that topical application of 4 drops of sunflower oil to each of three parts of the body twice daily for 4 weeks improves skin hydration, but not skin barrier function or the presence of redness or rash, when compared with not using topical oil. Furthermore, use of sunflower oil may impede the normal development of skin barrier function that occurs during the first four weeks of life (96144).
• Fetal and premature infant mortality. It is unclear if topical sunflower oil is beneficial for preventing early mortality in premature infants. Details: A large clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, reduces infant mortality by 58% when compared to a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. A subgroup analysis of premature infants also shows a 52% reduction in mortality with the use of high-linoleic acid sunflower oil when compared with control (108143). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
• Prematurity. Small to moderate-sized clinical studies suggest that topical sunflower oil might increase body weight, reduce length of hospital stay, and improve skin hydration and skin integrity in preterm neonates. Details: Preliminary clinical research in preterm infants with low birth weight shows that massaging for 5-10 minutes using sunflower oil 10 mL/kg three times daily for 2 weeks increases weight gain by approximately 35% over 2 months when compared with massage using no oil. Sunflower oil massage does not appear to increase length or head circumference (96145). A small clinical study in premature infants in the intensive care unit (ICU) shows that a similar massage with sunflower oil three times daily for 5 days shortens ICU stay by about 5 days when compared with no massage. Furthermore, over the ICU stay, infants in the sunflower oil massage group gained an average of 15 grams, whereas infants in the control group experienced weight loss (98479). The effect of sunflower oil on skin hydration and integrity in preterm infants has also been assessed. A clinical trial of 90 preterm infants in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with either sunflower oil or almond oil 4 mL/kg four times daily for 5 days improves measures of skin hydration and skin integrity when compared with control infants that did not receive oil treatment. The sunflower and almond oil treatments are equally effective (105524). Another clinical study in 90 infants (42% preterm) in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with sunflower oil or liquid Vaseline 3-4 mL for preterm and 5-6 mL for full-term infants daily for 16 days improves measures of skin integrity when compared with control infants that did not receive any oil treatment. Skin integrity scores were better in the sunflower oil group than liquid Vaseline at some time points (111726).
• Psoriasis. Although there is interest in using topical sunflower oil for psoriasis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Rheumatoid arthritis (RA). Although there is interest in using oral sunflower oil for RA, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Tinea pedis. It is unclear if topical sunflower oil is beneficial for tinea pedis. Details: Preliminary clinical research shows that topical application of a specific brand of ozonized sunflower oil (Oleozon) twice daily for 6 weeks is as effective as ketoconazole for curing athlete's foot (76687). More evidence is needed to rate sunflower oil for these uses.
