The Active Ingredient Is: Quercetin (aglycone form)

Quercetin is a simple bioflavonoid antioxidant found in lots of plants and foods, existing in its aglycone form in this supplement. This ingredient helps support normal cellular function and overall antioxidant protection.

Source material notes that this quercetin comes as a pure aglycone and is vegan-friendly, with plant-based, non-GMO and gluten-free excipients.

What Does Quercetin Do?

Quercetin acts as a natural antioxidant and bioflavonoid that helps guard cells from oxidative stress and supports vascular integrity by reducing LDL oxidation, in line with EFSA-style mechanistic concepts. It may contribute to immune resilience and healthy inflammatory responses as described in summaries of research.

Research indicates that quercetin supports cardiovascular and immune-related functions through its antioxidant activity and modulation of inflammatory pathways, with findings reported by Dr Li from a university in studies cited in notable journals.
