The Active Ingredient Is: Quercetin (Flavonoid)

Quercetin is a plant-based flavonoid that functions as a natural polyphenol with antioxidant properties. It supports vegan and allergen-free supplement lines and comes from plant materials including Sophora japonica, packed in a vegan capsule.

This formulation contains quercetin derived from plant sources and uses a plant-based capsule with no animal products. It is vegan and gluten-free, designed to align with plant-based dietary preferences.

What Does Quercetin Do?

Quercetin is involved in antioxidant activity and may help support normal immune function. It also plays a role in reducing inflammatory markers, and may aid in the perceived relief of allergy-related symptoms during daily activities.

In this product, quercetin is presented as the primary active nutrient, with the formulation designed to provide antioxidant support and potential immune and inflammatory response modulation within normal physiological processes.
