The Active Ingredient Is: Quercetin

Quercetin is a flavonoid with antioxidant properties and is often connected to immune support and overall vascular wellbeing. This formulation delivers highly bioavailable quercetin derived from Japanese sophora flower bud concentrate and boosted with fenugreek fibre to enhance absorption.

What Does Quercetin Do?

Quercetin helps with antioxidant activity and takes part in immune responses and endothelial function, supporting normal cardiovascular health. The fenugreek fibre blend helps maximise circulating levels of quercetin to optimise its action in the body.
