Quercetin is a flavonoid antioxidant with many anti-inflammatory properties. Pro Quercetin is effective in the management of hypersensitivity reactions (type I IgE-mediated reactions) that cause a histamine release, such as seasonal allergies.

Quercetin alleviates allergies by stabilizing the membranes of mast cells and basophils, preventing the release of histamine. It also blocks enzymes responsible for producing inflammatory mediators that sensitize the body’s pain receptors.

AOR Advantage

Most quercetin-based formulas are derived from citrus sources. This may be problematic as citrus is commonly allergenic. Pro Quercetin is derived from citrus-free sources to avoid sensitivity reactions. Pro Quercetin also includes 20 more capsules than AOR’s Quercetin to support longer therapeutic treatment schedules.

Discussion

Pro Quercetin is the flavone aglycone (non-sugar-bound) form of the polyphenolic flavonoid rutin. Quercetin is the major bioflavonoid in the human diet and an antioxidant for the maintenance of good health.

Anti-Allergy Effects

Quercetin counters allergic reactions by inhibiting the release of histamine via mast cell and basophil stabilization.

Several animal studies have demonstrated the positive effect of quercetin in preventing allergic reactions, including airway resistance. In one in vitro study quercetin was more effective than Cromolyn at inhibiting the release of IL-8 and TNF-alpha from mast cells. In two pilot clinical trials, quercetin also significantly decreased contact dermatitis.1

Immune-Modulating Effects

Quercetin is effective in reducing viral replication. Researchers have demonstrated that a quercetin-rich extract can upregulate antiviral responses in the immune system in response to infected cells.

Pain and Inflammation

Quercetin has cyclooxygenase (COX) and lipoxygenase (LOX) inhibiting actions. In preventing the formation of inflammatory mediators such as histamine, bradykinin and PGE2, it can also help prevent over-sensitizing of pain receptors.

In a 2017 clinical trial of women with rheumatoid arthritis, 500 mg of quercetin daily for eight weeks led to significantly less early morning stiffness and pain,  less post-activity pain, and reduced levels of TNF-alpha, compared to placebo.2

Cardiovascular Health

Quercetin promotes cardiovascular health by reducing LDL oxidation, enhancing nitric oxide (NO) production, and reducing the risk of metabolic syndrome. Additionally, quercetin has been shown in human studies to significantly decrease systolic and diastolic blood pressure in patients with stage 1 hypertension.3
