The Active Ingredient Is: Quercetin

Quercetin is a natural flavonoid with antioxidant powers that help keep normal cellular health and immune balance.

This formula uses clean quercetin as the active ingredient, sourced to highlight purity and quality in line with typical supplement practices.

What Does Quercetin Do?

Quercetin forms part of antioxidant defence and helps modulate inflammatory processes and immune activity, contributing to normal immune function as recognised in EFSA-aligned guidance.

Evidence suggests quercetin helps support capillary integrity and may influence metabolic and cardiovascular aspects through its biological actions, with findings discussed by Dr. Salehi from Tehran University.
