There was no overlapping transcript between the sets of differentially expressed genes between adipose tissue and liver. In the adipose tissue, out of 32 transcripts showing significantly higher expression in PD-Q compared to PD, the most upregulated one was glycoprotein M6A Gpm6a.
On the other hand, only 16 transcripts were downregulated by quercetin, including microRNA, Stonin 1 Ston1or regulated endocrine specific protein 18 Resp The Diseases and Functions analysis pointed to the cellular processes in the adipose tissue most impacted by quercetin administration, mostly pertaining to the aspects of lipid metabolism, cell cycle, and the conditions relevant to metabolic syndrome overweight disorder, insulin resistance as shown in Figure 4.

Metabolic syndrome MetS is a combination of cardiometabolic abnormalities, such as central obesity, hypertension, glucose intolerance and dyslipidemia, correlated with an increased risk for type 2 diabetes, cardiovascular disease, and all-cause mortality 23.
Quercetin, found naturally in numerous fruits and vegetables, is one of the most abundant flavonoids in the human diet Extensive evidence has demonstrated its favorable impact on human health, including various features of MetS, such as obesity, glucose intolerance and dyslipidemia In this study, we investigated the effects of quercetin on morphometric and metabolic parameters, as well as transcriptomic profiles in a highly inbred genetic rat model of MetS.
Even though the exact etiopathogenetic factors leading to the development of MetS remain to be elucidated, some investigators believe that an excess of abdominal visceral fat, being the most prevalent aspect of the syndrome, plays a major role in the process 3 Quercetin has been previously shown to exert an anti-obesity effect due to its anti-inflammatory and antioxidant properties, thus decreasing abdominal fat mass and abdominal circumference 30 — Likewise, in our study rats supplemented with quercetin showed lower weights of retroperitoneal and epididymal fat mass, both of which are considered a visceral fat.
However, no changes in total body weight were detected between the two tested groups. Moreover, we detected an increased weights of the heart and adrenal tissues in quercetin treated rats compared to controls.
Individuals with increased visceral fat deposition also typically evince insulin resistance and hyperinsulinemia, resulting in impaired glucose tolerance 33 In this study, we detected a significant decrease in the fasting insulin levels along with a lower postprandial blood glucose level at th min of the oral glucose tolerance test and smaller area under the glycemic curve in rats treated with quercetin.
All these findings were expected based on extensive evidence demonstrating strong antidiabetic effect of quercetin in both animals and humans 1435 In addition, some studies also described its possible beneficial effect in a prevention and treatment of long-term complications of diabetes, such as retinopathy, nephropathy, neuropathy, or atherosclerosis 36 — Furthermore, quercetin also protects pancreatic β-cells against damage, preserves their mass and function, and stimulates regeneration of β-cells 41 Atherogenic dyslipidemia, namely high triglycerides and low HDL-cholesterol levels, is an integral component of MetS and a major risk factor for developing cardiovascular diseases 43 Although quercetin seems to have a favorable effect toward normalizing blood lipid levels, the results are not consistent.
Many studies report very little or no improvement in lipid levels after quercetin administration 45 In this study, we detected no significant changes in total cholesterol and free fatty acid levels.

Free radicals do more than just damage cells. When in excess, they actually induce inflammation, which can present itself in a variety of ways—autoimmune conditions, aches and pains, poor immunity, and more. Studies show that quercetin supplementation may help to attenuate inflammation by reducing inflammatory markers in human cells, including tumor necrosis factor alpha turnover and interleukin-6 IL-6 4, 5. Another study looked at women with rheumatoid arthritis, an autoimmune condition, taking mg of quercetin daily for eight weeks 6. Results showed supplementation significantly reduced morning stiffness, morning pain, after-activity pain, and reduced markers of inflammation. Struggle with seasonal allergies? You can say goodbye to Benadryl. Quercetin combined with vitamin C is one of the most potent natural anti-histamines you can get. Research finds that quercetin may have anti-allergy properties that stimulate the immune system, inhibit histamine release, decrease pro-inflammatory cytokines, reduce leukotriene production, suppresses interleukin IL-4, and inhibits mast cell secretion Need a brain booster? Quercetin could be it. Despite relatively mixed reviews, some research suggests that supplementing with quercetin could improve exercise capacity. One study performed a systematic review of all available literature looking at quercetin and endurance exercise capacity and found that all studies combining VO2max and endurance performance measures indicated a significant effect favoring quercetin over the placebo However, they concluded that even though quercetin provides a statistically significant benefit to human endurance exercise capacity, the effect is too small to actually be considered as a performance aid. Polyphenols, of which quercetin is included, have been shown to modulate physiological and molecular pathways involved in energy metabolism, adiposity, and obesity. A team of researchers from the University of Georgia found that three potent polyphenols—resveratrol, genistein, and quercetin—work together to decrease fat accumulation in human fat cells.

Theoretically, Quercetin has the ability to decrease the creation of new fat cells whilst increasing the rate of at which fat cells are destroyed. It is also thought to control the rate at which enzymes associated with fat storage go about their functions. Additionally, studies on mice that were fed a high-fat diet have concluded that Quercetin supplementation did decrease the onset of obesity when compared to other mice consuming the same diet without a Quercetin supplement Although animal studies can be relevant in some situations, it appears that humans are quite different from mice when it comes to losing weight. One study of normal-weight women found no compelling evidence that Quercetin had a thermic fat-burning effect in humans when compared with placebo group On top of this other animal studies have also been inconsistent, with some even reporting weight gain as a result of Quercetin supplementation More research is certainly ideal at this point, but it appears that fat-burning is just not something Quercetin can help with in in humans.

| Quercetin Information | Mount Sinai - New York | Research studies confirm that quercetin is valuable for weight loss, and for achieving an optimal weight and BMI. Quercetin helped the women to lose weight, and it reduced an obesity marker called resistin. In another study published in , researchers confirmed that quercetin the inhibits fat formation or adipogenesis and calms inflammation. Adipogenesis can lead to central obesity, and it is considered a cornerstone function impacting the metabolism of many other tissues. It also suppressed the actions of mediator molecules called cytokines which could cause inflammation and fat formation and deposition, lipogenesis and adipogenesis. The data demonstrated that quercetin inhibits lipid accumulation and obesity-induced inflammation in both cell studies and in live subjects. Quercetin lowered insulin resistance, so that sugar and fat metabolism improved. It was found that quercetin reduced body weight gain from a high fat diet, and improved insulin sensitivity and glucose tolerance. The results indicated that quercetin can heighten glucose uptake in adipose tissues, and lower the levels of proinflammatory mediators called cytokines. Yet another important study showed that quercetin has a direct anti-obesity effect. It acts by turning off obesity genes that are linked to inflammation AMPK and MAPK pathways. This stops tissues from storing new fats and triggers the destruction of existing fat cells. Bromelain is a plant-based digestive enzyme complex from pineapple that breaks down proteins into their constituent amino acids. Because it enhances absorption, bromelain helps to move quercetin from the digestive tract into the bloodstream. One challenge with getting an adequate amount of quercetin is its low bioavailability; quercetin uptake take-up in human tissue is quite low. A clinically effective dose of bromelain significantly improves quercetin assimilation. Bromelain is also a highly effective anti-inflammatory in its own right. It can help to relieve joint and connective tissue pain, and reduce C-reactive protein, the inflammation marker. In these ways, bromelain magnifies the efficacy of quercetin. By calming inflammation, bromelain helps with achieving an ideal weight. Protein is essential for achieving an optimal weight, and bromelain frees up amino acids, the protein building blocks, so that they are better absorbed. Bromelain also has several helpful actions on fat or adipose tissue. In studies, bromelain inhibited the formation of new fat cells and caused fat cells to self-destruct. Additionally, research confirms that bromelain induces the breakdown of fats. Phytosome technology is a method of combining a nutrient with other natural plant substances to greatly enhance absorption, and to protect the nutrient from breakdown by gut enzymes. Quercetin is even more effectively assimilated when it is bonded to sunflower-sourced phospholipids. Because these phospholipids are chief components of human cell membranes, the phytosome complex they form together with quercetin is easily recognized by the body. Also, this phospholipid-quercetin phytosome is protected from destruction by digestive secretions and gut bacteria, and thus better absorbed. However, the researchers, based on the data, attributed this more to the exercise than the quercetin. While this type of study makes for nice headlines, all it really shows is something you already knew: exercise works. Quercetin, while not directly linked to weight loss, has been studied for its potential effects on exercise performance and endurance. Some studies suggest that quercetin can increase the number of mitochondria the energy-producing factories in our cells which can potentially improve athletic performance. However, the results for athletic performance are mixed. Some studies show a slight improvement in endurance or performance, while others find no significant difference. For the average person, the potential benefits of quercetin in exercise performance might not be noticeable. But for athletes or those looking for an edge in their training, it might be worth considering as part of a broader supplement and nutrition strategy. No, quercetin is not a weight loss supplement. While it offers numerous health benefits, direct weight loss is likely not one of them. Some studies suggest that quercetin can potentially improve athletic performance, but the results are mixed. Quercetin is naturally found in many fruits and vegetables such as apples, berries, onions, leafy greens, tomatoes, and citrus fruits.
