When compared to conventional treatments, flavonoids such as quercetin are known to prove an effective natural remedy for skin disorders.

Quercetin and mental health -

Quercetin, along with other flavonoids, may help inhibit the growth of many viruses. Diet plays an essential role in reducing the risk of cardiovascular diseases , such as heart disease and strokes.

Because fruit and vegetables contain flavonoids, eating more may help reduce the risk of these diseases. Research suggests that quercetin may help protect heart health by mitigating blood vessel dysfunction mitigating endothelial dysfunction, and reducing heart disease risk factors like high blood pressure and atherosclerosis.

According to a analysis , taking quercetin supplements could be an effective way to reduce blood pressure. Further research shows that people who were overweight and took a quercetin supplement of milligrams mg per day had lower levels of harmful cholesterol in their blood and reduced systolic blood pressure.

Systolic blood pressure measures the pressure in the blood vessels during a heartbeat. People can get quercetin through their diet by eating a range of fruit and vegetables daily. Onions are amongst the richest sources of dietary flavonoids you can eat, providing Quercetin is available as a nutritional supplement, typically in doses of to mg daily.

Supplements may also include other substances, such as bromelain or vitamin C, which may help the body absorb quercetin more effectively.

The natural antioxidants found in fruits and vegetables can be beneficial when consumed as part of a balanced and nutritious diet. However, quercetin may interact with some medications, so people should ask their doctor before taking a supplement.

Quercetin is a flavonoid found in fruit and vegetables. It has a wide range of benefits, which people can get by including a variety of fruit and vegetables in their diet. Although many studies have found several potential benefits of quercetin, many have been animal or in vitro studies.

Specifically, ashwagandha led to reductions in scores on the Hamilton Anxiety Scale in two studies, and in one study people taking ashwagandha has a We did a blog post devoted to L-Theanine which you can read here.

L-theanine is an amino acid found in tea leaves, particularly green tea. This amino acid helps to promote feelings of relaxation without causing drowsiness, which makes it a good go-to for daytime anxiety such as before a big meeting or a first date.

L-theanine works by influencing levels of neurotransmitters in the brain. Specifically, theanine increases production of the inhibitory neurotransmitter gamma amino butyric acid GABA and moderates the production of dopamine and serotonin.

Theanine supplementation leads to increased relaxation, reduced feelings of stress, and improvements in focus. L-theanine also results in a switch towards alpha brain wave patterns associated with calm alertness away from beta brain waves associated with anxiety and stress , particularly in the occipital and parietal regions of the brain, indicating a relaxation effect.

L-theanine has also been seen to improve responses in volunteers undertaking a stress task. Gene Food uses a proprietary algorithm to divide people into one of twenty diet types based on genetics.

High doses of B6 have been linked to nerve damage and even cancer over the long term, so consult with your doctor before starting a regimen and keep doses on the low side less than 10mg.

For more, see: B Vitamins and Cancer Risk: How to Make Smart Decisions. Magnesium is also an important nutrient for nerve health, relaxation, and sleep. This mineral is needed for muscles to relax, so can be helpful for anxiety-related muscle tension. Conversely, deficiencies can cause cramping and muscle spasms, as well as poor quality sleep and other issues.

A combination of magnesium and vitamin B6 has been shown to help relieve anxiety in people with premenstrual syndrome PMS. In one study, people who took mg of magnesium and 50 mg of vitamin B6 over four menstrual cycles had significant relief from PMS-related anxiety, compared to those taking a placebo or magnesium by itself.

In fact, the reported benefits of quercetin are wide ranging, from heart health to a natural remedy for leaky gut , however, it has also shown promise as a calming agent.

Studies show that quercetin helps to keep a lid on the fight or flight response of the adrenal system, leading to increased social interaction and a reduction in corticotropin releasing factor CRF which is a neuropeptide associated with anxiety and fear.

However, more research in humans is needed to understand absorption from both supplementation and food. Ansari, favors a food-first approach. Axe suggests placing more of these quercetin-rich foods on your plate:.

As of now, there are no specific public health recommendations for quercetin intake, such as dietary reference intakes DRIs or daily value amounts DV , from the Food and Drug Administration for the antioxidant, says Ansari.

According to Mount Sinai, quercetin is generally considered safe, yet pregnant and breastfeeding women and adults living with kidney disease should avoid taking this supplement. Typical side effects may include headache and upset stomach. Also, the integrated hospital system recommends taking periodical breaks from quercetin supplements since evidence suggests high doses may damage the kidneys.

Effect of CUS and quercetin treatment on animal behavior was assessed between day Afterward, the hippocampus was processed to evaluate neuronal damage, oxidative and inflammatory stress. Results revealed that stressed animals were highly anxious Elevated Plus Maze and Open Field , showed depressive-like behavior sucrose preference task , performed poorly in short-term and long-term associative memory task passive avoidance step-through task and displayed reduced locomotion open field.

Quercetin alleviated behavioral dysfunction in chronically stressed animals. To assess their brain biodistribution, rhodamine B isothiocyanate RBITC -labeled quercetin nanogels were administrated, and the fluorescence was analyzed.

It was found in Fig. Quercetin nanogels were quickly delivered to the brain region and predominantly accumulated in the brain at short time scales, suggesting their potential for targeted brain delivery via the intranasal route, which could be beneficial for treating depressive disorders.

To evaluate whether the quercetin nanogels improved in vivo bioavailability of quercetin, the corresponding plasma concentration vs. time Fig. The concentration vs. time curve of quercetin nanogels showed a sharp increase at approximately 15 min.

In contrast, oral administration of the quercetin reached a maximum plasma concentration of 4 h post-administration, resulting in a slower increase than quercetin nanogels. The intranasally administered quercetin nanogels exhibited a shorter T max and higher C max than orally administered quercetin, indicating rapid achievement of peak drug concentration.

Furthermore, the bioavailability of the intranasally administered quercetin nanogels was nearly 50 times greater than that of orally administered quercetin, as determined by relative bioavailability calculations. Therefore, the quercetin nanogels provide the potential to overcome BBB and enhance quercetin bioavailability at lower doses.

To investigate the potential antidepressant activities of quercetin nanogels, we tested the hypotheses using two models that contained intraperitoneal injection of reserpine and a well-established behavioral despair model.

A substantial dose of reserpine resulted in the depletion of noradrenaline, adrenaline, dopamine, and 5-HT in the brain for a duration exceeding 7 days. However, depressive behavior persisted for only 3 days [ 38 ]. Concurrently, the reserpine-induced model was chosen due to its straightforward procedure and high success rate, making it a suitable choice for evaluating the therapeutic efficacy of antidepressants.

A schematic diagram of the ptosis score of rats reduced by reserpine was indicated in Fig. The results suggested that the eyelid ptosis score of the administrated drugs was significantly lower than the model group induced by reserpine.

Also, quercetin nanogels significantly alleviated the depletion of 5-HT, NE, and DA in the striatum and hippocampus Fig. The antidepressant activities of quercetin nanogels and their BDNF delivery.

Behavioral tests are used to assess the behavioral characteristics after intranasal administration, including the open field test OFT , tail suspension test TST , and forced swimming test FST. The OFT was used to assess overall activity, anxiety-related behavior, and locomotor activity in a novel environment to rule out any inhibitory or excitatory effects of BDNF-quercetin nanogels [ 39 ].

The TST and FST were widely performed to investigate antidepressant activities and depression-like behavior of antidepressant drugs [ 40 , 41 ]. In the OFT of the mice, the significant differences were not discovered in the rearing times and total distance, as shown in Figure S4 a-b, compared to the control group, suggesting that the drugs had no impact on the tested mice.

In the TST and FST Fig. A preliminary study using two models manifested that BDNF-Quercetin nanogels had better antidepressant activities and were almost equal to the orally administrated fluoxetine and quercetin.

Still, a dose of the former was lower, showing their superiority of brain targeting by intranasal delivery. The CUMS model Fig.

It was observed that CUMS-induced weight loss and anhedonia were substantially mitigated by the experimental drugs, particularly BDNF-Quercetin nanogels, demonstrating a better effect on the stressed rats Fig.

The OFT was used to assess the exploratory behavior of the drug-treated CUMS rats after administration. It was indicated that fluoxetine, quercetin, quercetin nanogels, and BDNF-quercetin nanogels increased the number of rearings and the total distance of CUMS model Fig.

Both BDNF-quercetin nanogels and quercetin nanogels demonstrated more significant antidepressant effects than fluoxetine, as evidenced by the total distance. Plasma and hippocampal BDNF concentrations of the CUMS rats were markedly enhanced by the experimental drugs.

Notably, the hippocampal BDNF level in the BDNF-Quercetin nanogel group exhibited a significant change compared to the fluoxetine group. These findings suggested that the delivery of exogenous BDNF compensated for the loss of BDNF in the brain Fig.

Clinical reports and meta-analyses found that depressed patients had significant hypothalamic-pituitary-adrenal HPA axis hyperactivation. It was shown in Figure S5 a-c that the levels of corticotropin-releasing hormone CRH , adrenocorticotropic Hormone ACTH , and corticosterone in rats were significantly increased by CUMS.

However, the only level of corticosterone was decreased considerably by BDNF-Quercetin nanogels compared to CUMS rats. Many studies have found that testosterone had antidepressant effects in socially isolated male but not female rats [ 47 ].

It was observed in Figure S5 d that quercetin nanogels, in a dose-dependent manner, improved the testosterone level, and BDNF-Quercetin nanogels also showed a significant increase compared to CUMS rats.

In the meantime, inflammation was a crucial biological event that might increase the risk of major depressive disorders. CUMS-induced rats exhibited higher IL-6 and PGE 2 levels in plasma Fig.

Inflammatory levels of the rats were decreased after administration. BDNF-Quercetin nanogels also presented significant differences compared to those without administration. In summary, BDNF-Quercetin nanogels at a lower dose decreased the abnormal behavior of CUMS model and improved their biochemical indicators.

d Hippocampal CA3 pyramidal cells. Effects of BDNF-Quercetin nanogels on rat hippocampal pyramidal cells were investigated. Compared to CUMS model, these abnormalities were significantly improved by BDNF-Quercetin nanogels. Similarly, cell apoptosis and proliferation were also observed and analyzed by TUNEL and Ki67 staining, respectively.

The number of positive cells in CUMS rats significantly decreased Fig. BDNF-Quercetin nanogels significantly increased the corresponding positive cells. At the same time, these impairments of pyramidal cells were also found in the prefrontal cortex of CUMS rats Figure S6 , and BDNF-Quercetin nanogels showed the same therapeutic effects as in the hippocampus.

CUMS-induced cell apoptosis and proliferation in the hippocampus of rats. a TUNEL staining. b The nerve cells by TUNEL staining. c Ki67 staining. d Number of cell proliferation by Ki67 staining. Apoptosis is an essential mechanism of CUMS-induced depression [ 48 ]. As an anti-apoptotic endogenous membrane protein, B cell lymphoma-2 Bcl-2 prevents cells from entering the apoptotic program.

B-cell lymphoma extra-large Bcl-xL , like Bcl-2, is another antiapoptotic factor supporting neuronal survival but not promoting axon regeneration. BCL2-associated X Bax was a pro-apoptotic protein promoting cells to enter apoptosis. The study findings indicated that CUMS increased Bax mRNA expression in the hippocampal and prefrontal cortex tissues Figure S7 a, b and selectively decreased hippocampal Bcl-xL mRNA levels Figure S7 c, d without changing Bcl-2 mRNA expression Figure S7 e, f.

BDNF-quercetin nanogels exerted antidepressant effects on CUMS rats, mainly through anti-stress, anti-inflammation, and neuroprotection.

BDNF-quercetin nanogels can restore HPA axis function, inhibit neuron cell apoptosis, and promote neuron cell regeneration. To elucidate the impact of BDNF-Quercetin nanogels on CUMS rats, a comprehensive, integrated omics approach was used to investigate potential antidepressant mechanisms.

Gene expression of total mRNA isolated from rat hippocampus was assessed using RNA sequencing. The transcriptomic volcano map revealed that compared to CUMS group, genes were differentially expressed in the BDNF-quercetin nanogels group, with significantly up-regulated genes and significantly down-regulated genes Fig.

The most enriched GO terms in Fig. Gene set enrichment analysis GSEA was next performed using the KEGG Kyoto Encyclopedia of Genes and Genomes database, revealing significant enrichment including TGF-β and PI3K-Akt signaling pathway, glutamatergic synapse, alanine, aspartate, and glutamate metabolism Fig.

Additionally, GO terms associated with antioxidant activity were identified in Table S4. Oxidative phosphorylation was further found in KEGG pathway enrichment analysis. In line with previous studies on depression, it was found that there are glutamate receptor-related terms, PI3K-Akt, glutamatergic synapse, and glutamate metabolism signaling pathways.

These transcriptomic findings suggested that BDNF-Quercetin nanogels not only induced antioxidant activities via oxidative phosphorylation but also exerted antidepressant effects on CUMS rats by improving the glutamatergic system and PI3K-Akt signaling pathway. A metabolomic analysis was then performed to investigate the changes in hippocampal metabolites.

Partial least square analysis PLS-DA in Fig. Further analysis in Fig. The metabolic pathways associated with the antidepressant effects primarily encompassed the following biochemical process: 1 biotin metabolism; 2 citrate cycle; 3 tryptophan metabolism; 4 Alanine, aspartate, and glutamate metabolism; 5 thiamine metabolism Fig.

Taken together, transcriptomic and metabonomic data showed that the glutamatergic system and PI3K-Akt signaling pathway were the primary antidepressant mechanism of BDNF-Quercetin nanogels in CUMS rats.

Western blot experiments were performed to verify related protein expression. Protein expression of the glutamatergic system was demonstrated in Fig. These results presented that chronic stress significantly reduced the GRIA3 the receptor of AMPA protein content and increased the GRIN2B the receptor of NMDA protein content in the hippocampus of rats.

Moreover, BDNF-Quercetin nanogels regulated the PI3K-Akt signaling pathway by improving the abnormal expression of BDNF, TrkB, GSK3β, and p-mTOR after CUMS Fig. These results showed that exogenously supplemented BDNF might bind to its receptor TrkB and further activate the PI3K-Akt signaling pathway, thereby regulating the expression of abnormal GSK3β and p-mTOR proteins.

In summary, the protective effects of quercetin nanogels on BDNF were achieved by antioxidant activities associated with oxidative phosphorylation. By integrating omics prediction and protein expression verification, the results showed that BDNF-Quercetin nanogels exerted antidepressant effects on CUMS rats by modulating the glutamatergic system and PI3K-Akt signaling pathway.

In conclusion, quercetin nanogels were successfully prepared and characterized. Quercetin nanogels showed protective effects against protein damage, exhibited antioxidant activities without affecting cell viability, proliferation, and immune response, and increased in vitro inflammatory cytokine levels.

The intranasally administered quercetin nanogels rapidly distributed in the brain within 30 min and improved the bioavailability of quercetin nearly fold at a lower dose.

The BDNF-quercetin nanogels in the thermosensitive gel exhibited excellent thermosensitivity and co-delivered quercetin and BDNF slowly and sustainably. As a protein drug carrier, quercetin nanogels exerted antidepressant effects on reserpine-induced rats and alleviated the depletion of monoamine neurotransmitters.

BDNF-quercetin nanogels effectively reversed despair behavior in mice, alleviated weight loss and anhedonia in rats, ameliorated dramatic pyramidal cell damage in hippocampal CA1 and CA3 subregions and inflammatory cytokine levels, and ameliorated CUMS-induced cell apoptosis and proliferation in rat hippocampus.

Further omics analysis and protein verification revealed that the treatment of BDNF-Quercetin nanogels on depressive disorder was mainly related to the glutamatergic system, PI3K-Akt, and BDNF-TrkB signaling pathway. These results showed that the brain delivery of BDNF- Quercetin nanogels via intranasal administration has a significant potential for the combination treatment of depressive disorder.
