The Active Ingredient Is: Quercetin

Quercetin is a plant flavonoid that supports normal immune and antioxidant functions.

This formula combines quercetin with vitamin C and citrus bioflavonoids to support antioxidant capacity and immune resilience.

What Does Quercetin Do?

Quercetin helps support immune defence and antioxidant protection, especially when paired with vitamin C. Dr. Colunga Biancatelli of the University of Naples Federico II found that this combination can support immune health and antioxidant activity.

It participates in normal immune system function and protects cells from oxidative stress, aligning with EFSA-informed guidance on nutrient roles.
