The Active Ingredient Is: Quercetin

Quercetin is a natural flavonoid and a key bioflavonoid with roles in supporting normal immune and inflammatory processes. This formula combines quercetin with bromelain and vitamin C to potentially support histamine stability and antioxidant activity in everyday immune support contexts.

This formulation includes bromelain and vitamin C to assist the overall activity of quercetin, which helps maintain normal cellular functions linked to immune and inflammatory responses.

What Does Quercetin Do?

Quercetin contributes to the regulation of inflammatory pathways and stabilises the membranes of mast cells, which can help support normal immune responses. This mechanism aligns with evidence from studies evaluating histamine-related actions and anti-inflammatory effects.

Additionally, research suggests that the combination with bromelain and vitamin C may support these processes, contributing to overall immune resilience in adults experiencing seasonal discomforts, as discussed in expert reviews.

This section references Dr. Mlcek of the university in a study into quercetin's anti-inflammatory effects and supporting evidence for seasonal immune support.
