quercetin 95 Function&Application
95.0% Quercetin Powder, as the most common flavonoid compound, has various biological activities, can resist oxidation, and plays an important role in the clinical treatment of cardiovascular diseases.
1. Quercetin and Respiratory Health
Quercetin has a good expectorant, antitussive effect, and has a certain antiasthmatic effect, and has been used for a long time in the treatment of chronic bronchitis. The effects of quercetin on respiratory health are achieved through multiple pathways including mucus secretion, anti-viral, anti-fibrotic, and anti-inflammatory.
Quercetin also has a wide range of anti-fibrotic effects, including anti-liver, lung, heart and kidney fibrosis, and its mechanism of action is complex, including inhibition of fibroblast proliferation, collagen synthesis, prevention of oxidative damage, inhibition of angiogenesis, etc.
2. Antioxidant function of quercetin
Free radicals are normal metabolites in the body. When the free radicals in the body are excessive and unbalanced, it may lead to aging, inflammation, cardiovascular and cerebrovascular diseases, etc. Experiments show that flavonoids have good scavenging effects on free radicals and superoxide anions.
The antioxidant activity of quercetin protects the mucosal system in the following ways.
① quercetin 95 prevents lipid oxidation, and it is important to protect the lipid bilayer of the cell walls of the gastrointestinal tract, as these cells are an important part of the body's immune system;
②Quercetin may protect liver cells against alcohol-induced oxidative damage by reducing glutathione consumption, increasing antioxidant enzyme activity, and inhibiting lipid peroxidation. The protective effect is dose-dependent.
③ Quercetin increases the mucus secretion of gastric cells, and the mucopolysaccharide forms a buffer layer on the gastric mucosa, reducing the contact between gastric acid and the gastric wall.
Studies have found that supplementing quercetin with feed can not only significantly improve the antioxidant capacity of animal peripheral blood, but also save and protect vitamin C and vitamin E, indicating that quercetin can be directly or indirectly absorbed in the body after intestinal absorption. exert antioxidant effect.
3. Anti-inflammatory effect
4. Antibacterial effect
5. Skin pigmentation and skin protection
6. Cardiovascular protection
The effect of 95.0% Quercetin Powder on cardiovascular protection is mainly reflected in five aspects:
① Dilate blood vessels and lower blood pressure: For example, quercetin can inhibit the release of endothelin and reduce the tension of blood vessels, thereby lowering blood pressure.
②Prevention and treatment of coronary heart disease: Through animal experiments, the functions of reducing the incidence and mortality of myocardial infarction and lowering blood sugar were also found;
③ Reduce myocardial hypertrophy; quercetin can significantly inhibit the increase of total protein content of myocardial cells caused by angiotensin II, can significantly increase SOD activity, reduce MDA content, and has obvious preventive and therapeutic effects on myocardial cell hypertrophy.
④Inhibit the proliferation and hypertrophy of vascular smooth muscle cells;
⑤ Antithrombotic. Inhibition of thrombin causes the increase of platelet cytoplasmic free calcium [Ca2+], and inhibits platelet activation and aggregation, thereby indirectly protecting the cardiovascular system, dilating arteries, lowering blood pressure, anti-arrhythmic, inhibiting in vitro and in vivo Collagen, adenosine diphosphate, arachidonic acid (AA), etc. induce platelet aggregation and release of serotonin (5-HT).
What foods is quercetin found in?
quercetin 95 can be found in almost all plant foods. For example, foods like black tea, broccoli, onions, red apples, and red wine are some of the best sources of this nutrient. Quercetin supplements come in the form of concentrated powders, tablets or capsules. It's often packaged with bromelain, another substance that's helpful in treating allergies and inflammation, and boosts the body's absorption of quercetin. A typical ingested dose of quercetin is 100-250 mg three times a day.
