The Active Ingredient Is: Quercetin

Quercetin is a natural flavonoid with antioxidant properties, provided here as a high-purity anhydrous form for consistent quality.

This form is a high-purity anhydrous quercetin, suitable for vegetarian capsules, with the compound sourced to support standard antioxidant functions.

What Does Quercetin Do?

Quercetin demonstrates antioxidant activity and may support cardiovascular health, including endothelial function and blood pressure modulation. It also relates to immune function and oxidative stress biomarkers in scientific contexts.

Evidence suggests these effects are achieved through its action as an antioxidant and by influencing inflammatory pathways, aligning with EFSA-style nutrition guidance and normal physiological roles.

Dr. Patel of a major university found that quercetin contributes to antioxidant protection and supports vascular health in adults.
