CanPrev Quercetin 500 mg (120 Capsules)
 
CanPrev Quercetin 500 mg delivers a high-potency dose of pure quercetin, naturally sourced from the flower of the Japanese pagoda tree (Sophora japonica). Quercetin is a powerful plant-based antioxidant that helps protect cells from oxidative stress, supports immune function, and assists in tissue repair.
 
Quercetin is well known for its ability to stabilize mast cells and basophils, helping to regulate histamine release and reduce symptoms associated with seasonal allergies. Research also suggests quercetin may help support upper respiratory tract health, particularly during periods of immune challenge.
 
In addition to immune and allergy support, quercetin contributes to cardiovascular health by helping increase HDL (“good”) cholesterol levels and protecting LDL (“bad”) cholesterol from oxidation.

Why Quercetin Matters
Antioxidants play a vital role in maintaining immune balance. Quercetin supports immune function by helping immune cells communicate, reducing oxidative damage, and regulating inflammatory responses. Without adequate antioxidant support, inflammation can become chronic and may damage healthy tissues.
