A POTENT IMMUNE BOOSTER AND DETOXIFYING SUPPLEMENT.  IT ALSO PROTECTS THE BODY’S DNA AND ASSISTS AGAINST ALLERGIES

Quercetin is widely distributed in the plant kingdom and is the most abundant of the flavonoid molecules. It is found in many foods we often consume, including apples, onions, tea, berries, and brassica vegetables, as well as many seeds, nuts, flowers, barks, and leaves. It is also found in medicinal botanicals, including Ginkgo biloba, Hypericumperforatum(St. John’s Wort), Sambucuscanadensis(Elder), and many others. It is often a major component of the medicinal activity of the plant, and has been shown in experimental studies to have numerous effects on the body.

Quercetin appears to have many beneficial effects on human health, including cardiovascular protection, anti-cancer activity, anti-ulcer effects, anti-allergy activity, cataract prevention, antiviral activity, and anti-inflammatory effects.

Take 1 capsule twice a day.

60 Capsules – 1 month supply.

  • Allergies: Quercetin’s mast cell stabilizing effects make it an obvious choice for use in preventing histamine release in allergies, similar to the synthetic flavonoid analogue cromolyn sodium. Absorption of the pure aglyconequercetin is poor; however, much of quercetin’s anti-allergy effects may be due to its anti-inflammatory and anti-histaminic effects in the gut.

  • Cardiovascular Disease Prevention: Quercetin’s cardiovascular effects centre on its antioxidant and anti-inflammatory activity, and its ability to inhibit platelet aggregation ex vivo.  The Zutphen Elderly Study investigated dietary flavonoid intake and the risk of coronary heart disease. The risk of heart disease mortality decreased significantly as flavonoid intake increased.  Interestingly, the flavonoid-containing foods most commonly eaten in this study contained a high amount of quercetin (tea, onions and apples).   In a cohort of the same study, dietary flavonoids (mainly quercetin) were inversely associated with stroke incidence.

  • Inflammation: Quercetin is indicated in any inflammatory condition, as it inhibits the formation of the inflammatory mediators prostaglandins and leukotrines, as well as histamine release. This may be especially helpful in patients suffering from asthma, as leukotrine B4 is a potent bronchial constrictor. Quercetin’s inhibition of xanthine oxidase decreases the formation of uric acid, and may be of value in the treatment of gout.

  • Anti-ulcer/Gastroprotective effects: Animal studies have shown quercetin to be protective of gastric ulceration caused by ethanol, probably by inhibiting lipid peroxidation of gastric cells and/or by inhibition of gastric acid secretion.  An interesting aspect of quercetin’s anti-ulcer effect is that it has been shown to inhibit in vitro growth of Helicobacter pylori in a dose-dependent manner.

  • Cancer: As mentioned above, quercetin has been investigated in a number of animal models and human cancer cell lines, and has been found to have antiproliferative effects. It may also increase the effectiveness of chemotherapeutic agents.  More clinically-oriented research will have to be done in this area to discover effective dosage ranges and protocols.

  • Diabetic Complications: Quercetin’s aldose reductase-inhibiting properties make it a useful addition to diabetic nutritional supplementation, to prevent cataract and neurovascular complications.

HERB/PLANT EXTRACTS:

Quercetin

  • Flavonoids, as a rule, are antioxidants, and a number of quercetin’s effects appear to be due to its antioxidant activity.
  • Quercetin scavenges oxygen radicals, inhibits xanthine oxidase  and inhibits lipid peroxidation in vitro. 
  • As another indicator of its antioxidant effects, quercetin inhibits oxidation of LDL cholesterol in vitro.  This is possibly due to it inhibiting LDL oxidation itself, by protecting vitamin E in LDL from being oxidized or by regenerating oxidized vitamin E. 
  • By itself and paired with ascorbic acid, quercetin reduced the incidence of oxidative damage to neurovasculature structures in skin, and inhibited damage to neurons caused by experimental glutathione depletion.
  • Quercetin exerts antiviral activity against reverse transcriptase of HIV and other retroviruses, and was shown to reduce the infectivity and cellular replication of the Herpes simplex virus type 1, the polio-virus type 1, the parainfluenza virus type 3, and the respiratory syncytial virus (RSV).
  • Much of the recent research on quercetin has shown it to be an anticarcinogen to numerous cancer cell types, including breast, leukemia, colon, ovary, squamous cell, endometrial, gastric, and non small cell lung.

Bromelain

  • Bromelain is a natural, protein-digesting enzyme derived from pineapples. 
  • It has been used to increase absorption of compounds, including antibiotics.  Because of this, quercetin should be taken in combination with bromelain to improve its absorption. 
  • Also, bromelain has powerful anti-inflammatory properties that synergise the quercetin. 
  • Bromelain inhibits several other common inflammatory mediators, including bradykinin and fibrin.  For this reason it is widely used in sports medicine to reduce the pain and swelling of bruises, sprains, muscle tears, etc.

L-Glutamine

  • The amino acid, glutamine, may help repair damage to the intestines in cases of Irritable Bowel Syndrome, Colitis and Gastritis.
  • It may also accelerate the healing of peptic ulcers and prevent food allergies.
  • Glutamine added to Quercetin Assist enhances the general health of the digestive system, which is a source of energy for the intestines.
  • It also prevents intestinal permeability and repairs damage caused by Irritable Bowel Syndrome. It is very beneficial for Leaky Gut Syndrome.
