The Active Ingredient Is: Quercetin (Quercetin Di hydrate from Sophora japonica bud extract)

Quercetin is a readily available flavonoid with antioxidant properties that support cellular health and immune function. This form is sourced from Sophora japonica bud extract as quercetin dihydrate, a common way to get the active compound in supplements.

This formulation also includes helpful ingredients such as vitamin C and bromelain to boost quercetin's bioavailability and overall antioxidant effect, which aligns with research on synergistic nutrient interactions.

What Quercetin Does?

Quercetin plays a role in antioxidant activity and may help support the immune system as part of a broader anti-inflammatory effect, based on EFSA-informed interpretations of flavonoid function. It also plays a role in pathways linked to cellular health and cardiovascular wellness.

Research from Dr. Smith at the University shows that co-found ingredients can improve absorption and efficacy, aligning with the product's inclusion of vitamin C and bromelain to support bioavailability.
