What the research says about quercetin
Educational summaries of published research on quercetin, liposomal delivery technology, and vitamin E; not product-specific claims. CanPrev Liposomal Quercetin's own authorized use under NPN 80120631 is that it is an antioxidant that helps protect cells and reduces oxidative damage caused by free radicals, and a source of vitamin E for the maintenance of good health.
PEGylated quercetin liposomes achieved 89% encapsulation efficiency
A quercetin-loaded PEGylated liposome formulation achieved 88.85% encapsulation efficiency and remained physically stable for at least 21 days at 4C, illustrating one approach researchers use to stabilize quercetin in a liposomal delivery system.
Preclinical studyComparing liposomal and liquid-crystalline nanoparticle carriers for quercetin
Researchers developed and physicochemically characterized quercetin-loaded liposomes (using hydrogenated soy phosphatidylcholine) alongside liquid crystalline lipid nanoparticles, finding that non-ionic surfactants improved the stability and encapsulation efficiency of the liposomal carrier.
Preclinical studyLiposomes helped shield quercetin from breakdown by liver enzymes in vitro
A comparative study of quercetin-loaded liposomes and nanocochleates found the liposomal form achieved 74.2% encapsulation efficiency and extended in vitro release to 24 hours, part of ongoing research into carrier systems designed to protect quercetin from rapid liver metabolism.
Preclinical studyQuercetin's poor water solubility is a well-documented formulation challenge
A drug-design review describes quercetin's low water solubility, molecular instability and limited absorption as central obstacles to its bioavailability, and surveys delivery systems - including liposomes, nanoparticles and cyclodextrin complexes - developed to address them.
ReviewFlavonoids like quercetin are poorly absorbed in their plain form
A pharmaceutics review of poorly water-soluble flavonoids, including quercetin, summarizes formulation strategies - carrier complexes, nanotechnology and absorption enhancers - developed to improve their low oral bioavailability, dissolution rate and gastrointestinal permeability.
ReviewA more bioavailable quercetin form improved blood vessel function acutely
In a randomized crossover study, a quercetin derivative with roughly 17-fold higher bioavailability than plain quercetin significantly improved flow-mediated dilation (a measure of blood vessel function) 1.5 hours after intake in adults with cardiovascular risk factors, compared with placebo.
Human RCTQuercetin supplementation reduced inflammatory markers in at-risk adults
In a randomized, placebo-controlled crossover trial, 4 weeks of quercetin-3-glucoside (160 mg/day) reduced the endothelial marker sE-selectin and the inflammatory marker IL-1beta in (pre)hypertensive men and women, alongside an improved composite inflammation score.
Human RCTA single quercetin dose did not change blood pressure after a high-fat meal
In overweight-to-obese hypertensive adults, adding 54 mg of quercetin to a single high-fat, high-carbohydrate test meal did not significantly alter postprandial blood pressure or several endothelial function markers compared with placebo, in a randomized crossover trial.
Human RCTCirculating quercetin metabolites tracked with improved vessel dilation
In a dose-response crossover study of cranberry polyphenols, twelve plasma polyphenol metabolites - including a quercetin glucuronide - correlated with the degree of improvement in flow-mediated dilation observed after intake, linking quercetin metabolites to vascular effects.
Human RCTNano-formulated quercetin activated the cell's own antioxidant enzyme system
In human vascular smooth muscle cells stressed with TGF-beta, quercetin encapsulated in solid lipid nanoparticles activated the Nrf2 pathway and upregulated the antioxidant enzymes HO-1, GPx and SOD1, reducing reactive oxygen species alongside curcumin in a combination treatment.
Preclinical studyA quercetin-related compound protected heart cells via the Nrf2 pathway
Spiraeoside, a naturally occurring quercetin glucoside, protected cultured human cardiomyocytes from high-glucose-induced oxidative stress and cell injury by activating the PI3K/Akt/Nrf2 signaling pathway and increasing antioxidant enzyme activity.
Preclinical studyVitamin E's core job is protecting cell membranes from oxidation
A widely cited review concludes that alpha-tocopherol's (vitamin E's) principal biological function is acting as a lipid-soluble peroxyl radical scavenger, protecting the polyunsaturated fatty acids in cell membranes from oxidative damage.
ReviewQuercetin reduced post-exercise illness in a cyclist trial
In trained male cyclists completing 3 days of intensive cycling, 3 weeks of quercetin (1,000 mg/day) significantly reduced the incidence of upper respiratory tract infections in the 2 weeks afterward (1 of 20 vs 9 of 20 with placebo), though it did not change several direct measures of immune cell function.
Human RCTA 160km ultramarathon trial found no effect of quercetin on illness rates
In ultramarathoners racing the 160 km Western States Endurance Run, 3 weeks of quercetin (1,000 mg/day) before and 2 weeks after the race did not reduce post-race illness rates or counter the drop in natural killer cell activity and salivary IgA seen after the event.
Human RCTA review of nutrition strategies to counter exercise-induced immune dips
A review of immunonutrition research in athletes discusses quercetin alongside beta-glucan and curcumin as supplements studied for their potential to lessen exercise-induced immune perturbations and reduce upper respiratory tract infection risk after heavy exertion.
ReviewA phase 2 trial tested quercetin plus dasatinib in postmenopausal women
In a phase 2 randomized trial of the senolytic combination dasatinib plus quercetin in 60 postmenopausal women, the primary bone-resorption marker did not differ from control overall, though women with a higher senescent-cell burden showed increased bone-formation markers and bone density gains in exploratory analyses.
Human RCTDasatinib plus quercetin reduced kidney senescence markers in diabetic mice
In a mouse model of diabetic kidney disease, a short course of dasatinib plus quercetin improved kidney function, reduced senescence and inflammation markers, and increased geroprotective factors, building on the same research group's earlier pilot human trial of the combination.
Preclinical studyA review maps senolytic research, including quercetin, in artery disease
A pharmacology review describes how senolytic agents such as dasatinib combined with quercetin or fisetin are being investigated for their ability to clear senescent cells that accumulate in atherosclerotic plaques, while noting that dosing and long-term safety in cardiovascular patients still require dedicated clinical trials.
ReviewQuercetin outperformed a standard mast cell stabilizer in lab testing
In cultured human mast cells, quercetin inhibited release of the inflammatory mediators IL-8 and TNF more effectively than cromolyn (the only marketed mast cell stabilizer), and in two small open-label pilot trials was associated with improvements in contact dermatitis and photosensitivity.
Preclinical + pilot trialQuercetin blocked a receptor pathway involved in non-allergic reactions
In mouse and cell-based models, quercetin dose-dependently reduced histamine release, calcium signaling and swelling triggered through the Mrgprx2 receptor, a pathway implicated in drug-related pseudo-allergic reactions.
Preclinical studyA quercetin supplement eased seasonal allergy symptoms in a 4-week trial
In a randomized, double-blind, placebo-controlled trial, adults with pollinosis taking a bioavailable quercetin supplement (200 mg/day) for 4 weeks showed significant improvement in eye itching, sneezing, nasal discharge and quality-of-life scores compared with placebo.
Human RCTA safety review flagged gaps in long-term, high-dose quercetin data
A safety review of isolated quercetin supplements found reported adverse effects are rare and mild, but noted that adequate long-term (over 12 weeks) safety data at high doses (1,000 mg or more per day) are not yet available, and flagged potential drug interactions and effects on damaged kidneys as areas warranting caution.
ReviewQuercetin can alter how the body handles certain other medications
Quercetin inhibited a drug-transport protein (BCRP) in cell models and increased blood levels of the drug sulfasalazine when given beforehand in rats, evidence that high dietary or supplemental quercetin intake can meaningfully change the pharmacokinetics of some co-administered medications.
Preclinical studyA 6-week human trial monitored liver, kidney and blood safety markers
In a randomized, placebo-controlled crossover trial, 150 mg/day of quercetin for 6 weeks reduced systolic blood pressure and oxidized LDL in overweight adults, and blood tests of liver function, kidney function, hematology and electrolytes showed no adverse changes versus placebo.
