Description
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.
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.
- Helps prevents symptoms of allergies including itchy eyes, itchy throat, sneezing and nasal congestion
- Promotes cardiovascular and immune health
- Inhibits enzymes responsible for the production of inflammatory mediators
- Citrus-free for those with sensitivities
Frequently Asked Questions
What is AOR Pro Quercetin, and what is it used for?
A 120-capsule quercetin supplement providing 500 mg of quercetin per capsule, derived from Brazilian rue (Ruta graveolens) rather than citrus sources, taken 1 capsule twice daily with food. Quercetin is a flavonoid antioxidant that stabilizes mast cells and basophils to reduce histamine release, supports cardiovascular and immune health, and inhibits enzymes that produce inflammatory mediators. The formula contains no citrus-derived ingredients — important for those with citrus sensitivities who want allergy relief.
What are the ingredients in AOR Pro Quercetin and how does quercetin work?
Each capsule contains 500 mg of quercetin from Brazilian rue (Ruta graveolens). Quercetin stabilizes mast cell and basophil membranes, preventing histamine release in response to allergens. It also inhibits COX and LOX enzymes that produce inflammatory prostaglandins and leukotrienes, reducing both inflammation and pain signaling. Additionally, it modulates the Th1/Th2 immune balance and provides cardiovascular antioxidant support. Excipients: microcrystalline cellulose, sodium stearyl fumarate, HPMC capsule — no citrus-derived excipients of any kind.
Who should take AOR Pro Quercetin, and how is it used?
For adults seeking relief from seasonal allergies (itchy eyes, sneezing, nasal congestion), those with chronic inflammatory conditions, or supporting cardiovascular and immune health. Take 1 capsule twice daily with food. Those with citrus allergies can use this product without concern, as it contains no citrus-derived ingredients. Consult a physician if pregnant or breastfeeding. Note: applications in pulmonary nodule management have been reported; clinical evidence remains limited.
How does AOR Pro Quercetin differ from other quercetin supplements?
The majority of quercetin supplements are derived from citrus fruit peels — a significant paradox for allergy sufferers, since citrus is a common allergen and cross-reactant. AOR Pro Quercetin sources quercetin from Brazilian rue (Ruta graveolens), a non-citrus botanical, eliminating this risk entirely. The 500 mg per capsule at 1,000 mg total daily dose matches the therapeutic dosing used in anti-inflammatory and allergy research. The 120-capsule count provides a 60-day supply at therapeutic dosing — better value than the 100-capsule packs common in competing products at the same dose.
What is AOR (Advanced Orthomolecular Research) and are its supplements safe in Canada?
AOR, short for Advanced Orthomolecular Research, is a Calgary, Alberta-based supplement brand founded in 1991 by Dr. Traj Nibber, PhD. Built on the orthomolecular medicine principles of Nobel laureate Linus Pauling — the right molecule, in the right dose, at the right place and time — AOR products are manufactured in a cGMP-compliant facility in Alberta and all carry Health Canada Natural Product Numbers (NPN). Raw materials are independently tested in ISO-certified laboratories for purity, potency, and safety. Products are commonly recommended by naturopathic doctors and integrative healthcare practitioners across Canada.
What makes AOR different from other supplement brands?
AOR's real distinction is its orthomolecular research model: rather than formulating to meet basic RDAs, AOR targets functional, clinically studied dosing levels — and has a track record of introducing compounds to the Canadian market before they became mainstream, including D-ribose, R-lipoic acid, and strontium citrate. AOR also consistently chooses bioavailable ingredient forms over cheaper alternatives: methylated B vitamins (methylcobalamin, L-5-MTHF) instead of cyanocobalamin; chelated magnesium bisglycinate instead of magnesium oxide. This research-first approach, developed in close collaboration with naturopathic doctors, is what separates AOR from brands that replicate popular formulas at lower cost.
