The Active Ingredient Is: Quercetin Dihydrate

Quercetin dihydrate is essentially a flavonoid antioxidant that helps support immune balance and normal inflammatory responses, and this form is commonly used for its claimed biological activity in whole-food and supplement contexts.

This formula also includes bromelain from pineapple stem, which can help enhance quercetin absorption and support anti-inflammatory actions in the body.

What Does Quercetin Dihydrate Do?

Quercetin helps keep antioxidant protection and participates in the regulation of inflammatory processes, contributing to overall immune on‑going balance. It is involved in normal cellular defence mechanisms, as recognised in EFSA-based guidance.

In combination with bromelain, quercetin supports a multitargeted approach to wellness by modulating inflammatory responses and supporting immune balance, with the two actives working together in line with scientific context.
