Dietary Sources Fruits and vegetables are the primary dietary sources of quercetin, particularly citrus fruits, apples, onions, parsley, sage, tea, and red wine.
Available Forms Quercetin supplements are available as pills or capsules. How to Take It Pediatric There is not enough evidence to recommend quercetin for children.
Adult Recommended adult dosages of quercetin vary depending on the condition being treated. Precautions Quercetin is generally considered safe. Pregnant women, breastfeeding women, and people with kidney disease should avoid quercetin.
At doses greater than 1 g per day, there have been reports of damage to the kidneys. Possible Interactions If you are being treated with any of the following medications, you should not use quercetin supplements without talking to your health care provider first. Antibiotics There is some concern that quercetin may reduce the effectiveness of certain antibiotics.
Anticoagulants blood thinners Quercetin may enhance the effect of these drugs, increasing your risk for bleeding. Anticoagulants include: Warfarin Coumadin Clopidogrel Plavix Aspirin Chemotherapy Test tube and animal studies suggest that quercetin may enhance the effects of doxorubicin and cisplatin, which are two chemotherapy medications used to treat cancer.
Corticosteroids Quercetin may cause these drugs to stay in the body longer. Cyclosporine Quercetin may interfere with the body's absorption of this drug, which is used to suppress the immune system. Digoxin Concomitant use may increase the risks of digoxin.
Fluoroquinolones Concomitant use may reduce the effectiveness of fluoroquinolones. Medications changed by the liver Since quercetin affects the liver, concomitant use with medications that are changed by the liver may alter how the body metabolizes these medications.

In this project, three nanoformulations approaches smartCrystals®, lipid nanocapsules and liposomes were tested for the increase of quercetin water solubility.
The formulations were optimized for scale up to industrial scale at the level of preparation method, also in the excipients compositions for higher affinity to quercetin. The formulations were characterized in terms of particle size, PDI, quercetin loading, crystallinity evaluation and quercetin in vitro release profile.
Then, formulations were compared in interaction with HaCaT and THP-1 cells for their cellular toxicity and protective activity. Finally, two formulations quercetin smartCrystals® with TPGS and quercetin lipid nanocapsules 20 were selected and compared for the enhancement of the in vivo skin penetration of quercetin.
This project propose a solution for the successful formulation of quercetin enabling its efficient skin delivery. This project can be extrapolated to industrial level for quercetin and other poorly water soluble molecules that present limited efficiency due to their low skin penetration capacity.

Quercetin belongs to a group of plant pigments called flavonoids that give many Qyercetin, Carbohydrates and Glycemic Index, and vegetables Carbohydrates and Glycemic Index colors. Gestational diabetes complications, such as quercetin, are antioxidants. They scavenge Qkercetin in the prtection known as free radicals which damage cell membranes, tamper with DNA, and even cause cell death. Antioxidants can neutralize free radicals. They may reduce or even help prevent some of the damage free radicals cause. In test tubes, quercetin has strong antioxidant properties. But researchers are not sure whether taking quercetin and many other antioxidants has the same effects inside the body.Quercetin and skin protection -

| Dietary Sources | This can directly influence the skin absorption and in vivo effects of the ingredient. Quercetin and its derivatives are naturally occurring phytochemicals with promising bioactive effects. It has a versatile role in the skin and body as it possesses biological activities that target different mechanisms to combat damage from both intrinsic and extrinsic factors. The major role it has in skincare is anti-aging through its antioxidant and anti-inflammatory properties. It has potent effects to protect our skin from premature aging, making it a superior active in restorative skincare. In cell models, quercetin is shown to inhibit lipopolysaccharide LPS -induced TNF-α and IL-8 expression, and the production of pro-inflammatory enzymes cyclooxygenase COX and lipoxygenase LOX. Quercetin significantly decreased both IL-6 and IL-8 even in very low concentrations. Adapted from: Lim, H. Inhibitory Effect of Quercetin on Propionibacterium acnes-induced Skin Inflammation. International Immunopharmacology , 96 , In UV-induced skin damage, it demonstrates protective effects by inhibition of metalloproteinase-1 MMP-1 , a protease enzyme that breaks down collagen, and downregulation of MMP-1 expression by preventing AP-1 activation. It interferes with several signal transduction pathways to stimulate NF-κB antagonist activity, and the blockage of cytokine-mediated induction of inflammatory cascades and ILstimulated IL-6 production from human mast cells. The immunomodulatory activity of quercetin in murine models also includes the inhibition of TNF-α expression and activity, as well as nitric oxide production and downregulation of nitric oxide synthase. In acute inflammation, quercetin functions in a dose-dependent manner to suppress leukocyte recruitment, decrease lipid peroxidation and chemokine and ROS levels, and increase antioxidant enzyme activity. It interferes with the production and balance of pro-inflammatory cytokines such as TNF-α and IL, and anti-inflammatory cytokines such as IL It also has shown a synergistic effect with Vitamin C as ascorbate is able to recycle quercetin, thus, increasing its efficacy. Quercetin has skin-soothing and restorative effects that stimulate repair in damaged and aging skin by promoting recovery of the skin barrier, restoring normal hydration level, and preventing moisture loss from UV and chemical exposure. Its antioxidant properties protect the skin from damage due to chronic oxidative stress, increasing cellular survival. Objective: To investigate the influence of quercetin and its derivative on cytoprotective and antioxidant activity in fibroblasts. The cells treated with diluent were part of the control group. A fluorescent dye was added to the cell cultures with the compounds for the detection of reactive oxygen species ROS. In a separate set of cultures with the same concentrations of QUER and QU-CAP, ROS and oxidized protein levels were measured after incubation with μM hydrogen peroxide. Results: A reduction in the levels of ROS and oxidized proteins was observed after QUER and QU-CAP treatment, as compared to the control. Conclusions: QUER and QU-CAP exhibit cytoprotective properties against hydrogen peroxide-induced oxidative stress. Chondrogianni N, Kapeta S, Chinou I, Vassilatou K, Papassideri I, Gonos ES. Anti-ageing and rejuventating effects of quercetin. Exp Gerontol. doi: Objective: To investigate the influence of QUER and QU-CAP on cell survival in fibroblasts. After 5 days of recovery, the number of cells in each culture was enumerated. Results: The survival rate in the treated cells with QUER and QU-CAP ranged from 5. Objective: To investigate the influence of QUER and QU-CAP on cellular lifespan, and rejuvenating effect in fibroblasts. β-galactosidase activity was measured at the end of the treatment period to assess the rejuvenation effect of QUER and QU-CAP. Results: All concentrations of QUER and QU-CAP produced much higher cellular proliferation rates, as compared to the untreated control. Treated cells also had more elongated phenotype and lower percentage of β-galactosidase staining, which are linked to rejuvenating effects. Objective: To investigate the whitening effect of QUER and QU-CAP in melanocytes. Proteins were extracted at the end of the hour treatment and assayed to determine whether QUER and QU-CAP had influenced: 1 expression of tyrosinase, an enzyme that catalyzes several steps in melanin biosynthesis; and 2 CT-L proteasome activity at 24 hours , which is thought to mediate tyrosine degradation. Results: QUER and QU-CAP reduced the level of tyrosinase expression and stimulated CT-L proteasome activity. Objective: To investigate the effect of QUER and QU-CAP on proteasome activity in HFL-1 cells. CT-L proteasome activity was measured at the end of the treatment. Results: CT-L activity was increased by ~2. The expression of representative CT-L proteasome subunits was also enhanced by QUER and QU-CAP-treated cells. Conclusions: QUER and QU-CAP are potential proteasome activators that promote proteasome-mediated tyrosine degradation. This property, in addition to its antioxidant activity and rejuvenating effect suggests the use of QUER and its derivatives in topical anti-aging products. Objective: To evaluate the ability of quercetin to reduce skin inflammation induced by UV radiation, histamine, and chemical irritants. Route of Administration: Topical, in vivo. The skin condition in each quadrant was assessed pre- and post-therapeutic treatment. Results: UV-induced erythema was decreased by ~ After 30 minutes of treatment, Quercevita® was able to reduce the mean wheal diameter from the histamine prick test by The itching sensation also improved after 10 minutes of application of Quercevita® and Polaramin®. SLS-induced erythema was reduced, and hydration values were increased after treatment with Quercevita® at 2 hours and Polaramin® at 4 hours, with a positive trend over time. These formulations had a similar effect on GA-induced erythema and hydration values. The negative control and placebo had statistically insignificant effect in all quadrants. Conclusions: Quercetin has skin protective properties against UV damage, histamine, and chemical irritants by reducing redness, itching, inflammation, restoring the skin barrier, increasing hydration, and minimizing water loss.

Clin Cosmet Investig Dermtol. Objective: To investigate the senolytic effects of quercetin. Subjects: Cell culture 3T3-L1 pre-adipocytes, and mature adipocytes. Methods: Senescence and oxidative damage was induced with hydrogen peroxide at a sub-lethal concentration of μM for 3 hours for 3 consecutive days, and then treated with 20 μM quercetin. The following properties in each cell line were assessed: cytotoxicity, morphology, ROS levels, senescence-associated β-galactosidase SA-β-gal staining, and protein expression. Results: Following hydrogen peroxide-induced senescence in 3T3-L1 and mature adipocytes, an increase in ROS accumulation, and gene expression of SA-β-gal and p21 was observed. In mature adipocytes, the accumulation of ROS from induced oxidative damage produced a phenotype with enhanced expression of TNF-α, IL-6, iNOS, and NF-κB. Treatment with 20 μM quercetin in mature adipocytes significantly reduced the expression of SA-β-gal, p65 and SIRT 1, intracellular accumulation of ROS, inflammatory gene expression of IL-6 and MCP-1, and modulated the expression of miRp. In 3T3-L1 cells, 20 μM quercetin reduced SA-β-gal activity, ROS accumulation, expression of p65 and pro-inflammatory cytokines IL-6 and MCP-1, and modulated the expression of miRp, but increased SIRT 1 expression. Senolytic effects were observed in mature adipocytes and pre-adipocytes following treatment with 20 μM quercetin with no cytotoxicity in either cell line. Conclusions: The results confirmed the senolytic and anti-inflammatory role of quercetin in senescent pre-adipocytes and adipocytes, which may be related to anti-aging effects.

Senolytic effects of quercetin in an in vitro model of pre-adipocytes and adipocytes induced senescence. Despite the diverse benefits of quercetin, a challenge to overcome is its poor skin permeability and water solubility. To enhance skin permeability, quercetin can be encapsulated in ceramide liposomes, which is a phospholipid-based delivery system, and incorporated into a hydrogel base. This is believed to be a potential solution for drug delivery of water-insoluble compounds and enhance transdermal permeation of such antioxidants.

Treated cells also had more elongated phenotype and lower percentage of β-galactosidase staining, which are linked to rejuvenating effects. Objective: To investigate the whitening effect of QUER and QU-CAP in melanocytes. Proteins were extracted at the end of the hour treatment and assayed to determine whether QUER and QU-CAP had influenced: 1 expression of tyrosinase, an enzyme that catalyzes several steps in melanin biosynthesis; and 2 CT-L proteasome activity at 24 hours , which is thought to mediate tyrosine degradation. Results: QUER and QU-CAP reduced the level of tyrosinase expression and stimulated CT-L proteasome activity. Objective: To investigate the effect of QUER and QU-CAP on proteasome activity in HFL-1 cells. CT-L proteasome activity was measured at the end of the treatment. Results: CT-L activity was increased by ~2. The expression of representative CT-L proteasome subunits was also enhanced by QUER and QU-CAP-treated cells. Conclusions: QUER and QU-CAP are potential proteasome activators that promote proteasome-mediated tyrosine degradation. This property, in addition to its antioxidant activity and rejuvenating effect suggests the use of QUER and its derivatives in topical anti-aging products. Objective: To evaluate the ability of quercetin to reduce skin inflammation induced by UV radiation, histamine, and chemical irritants. Route of Administration: Topical, in vivo. The skin condition in each quadrant was assessed pre- and post-therapeutic treatment. Results: UV-induced erythema was decreased by ~ After 30 minutes of treatment, Quercevita® was able to reduce the mean wheal diameter from the histamine prick test by The itching sensation also improved after 10 minutes of application of Quercevita® and Polaramin®. SLS-induced erythema was reduced, and hydration values were increased after treatment with Quercevita® at 2 hours and Polaramin® at 4 hours, with a positive trend over time. These formulations had a similar effect on GA-induced erythema and hydration values. The negative control and placebo had statistically insignificant effect in all quadrants. Conclusions: Quercetin has skin protective properties against UV damage, histamine, and chemical irritants by reducing redness, itching, inflammation, restoring the skin barrier, increasing hydration, and minimizing water loss.

Clin Cosmet Investig Dermtol. Objective: To investigate the senolytic effects of quercetin. Subjects: Cell culture 3T3-L1 pre-adipocytes, and mature adipocytes. Methods: Senescence and oxidative damage was induced with hydrogen peroxide at a sub-lethal concentration of μM for 3 hours for 3 consecutive days, and then treated with 20 μM quercetin. The following properties in each cell line were assessed: cytotoxicity, morphology, ROS levels, senescence-associated β-galactosidase SA-β-gal staining, and protein expression. Results: Following hydrogen peroxide-induced senescence in 3T3-L1 and mature adipocytes, an increase in ROS accumulation, and gene expression of SA-β-gal and p21 was observed. In mature adipocytes, the accumulation of ROS from induced oxidative damage produced a phenotype with enhanced expression of TNF-α, IL-6, iNOS, and NF-κB. Treatment with 20 μM quercetin in mature adipocytes significantly reduced the expression of SA-β-gal, p65 and SIRT 1, intracellular accumulation of ROS, inflammatory gene expression of IL-6 and MCP-1, and modulated the expression of miRp. In 3T3-L1 cells, 20 μM quercetin reduced SA-β-gal activity, ROS accumulation, expression of p65 and pro-inflammatory cytokines IL-6 and MCP-1, and modulated the expression of miRp, but increased SIRT 1 expression. Senolytic effects were observed in mature adipocytes and pre-adipocytes following treatment with 20 μM quercetin with no cytotoxicity in either cell line. Conclusions: The results confirmed the senolytic and anti-inflammatory role of quercetin in senescent pre-adipocytes and adipocytes, which may be related to anti-aging effects.

Senolytic effects of quercetin in an in vitro model of pre-adipocytes and adipocytes induced senescence. Despite the diverse benefits of quercetin, a challenge to overcome is its poor skin permeability and water solubility. To enhance skin permeability, quercetin can be encapsulated in ceramide liposomes, which is a phospholipid-based delivery system, and incorporated into a hydrogel base. This is believed to be a potential solution for drug delivery of water-insoluble compounds and enhance transdermal permeation of such antioxidants. Programmed cell death, a process that is involved in the elimination of damaged cells or cancer cells, and aging. Cyclooxygenase-2; an enzyme that is expressed during an inflammatory response. A small protein that is secreted during an inflammatory response to facilitate cell signaling and immune function. Interleukin; a cytokine that is secreted during an inflammatory response to signal the migration of immune cells to the site of inflammation. A type of immune cell that contains granules rich in histamine and heparin; these cells go through degranulation to elicit inflammatory actions. Matrix metalloproteinases; protease enzymes that break down collagen and are responsible for tissue repair and remodeling. Nuclear factor kappa B; a transcription factor that regulates the expression of genes important for cell survival and cytokine production. SIRT; enzymes that regular cellular functions including aging, inflammation, detoxification, metabolism, and circadian rhythm.
