The Active Ingredient Is: Quercetin (Quercetin Dihydrate Form)

Quercetin is a natural bioflavonoid with antioxidant properties, here provided as quercetin dihydrate. This form shows up a lot in dietary supplements and helps keep nutrient activity steady in the body.

This blend combines quercetin with a vitamin C boost and a food-source mix to boost bioavailability and give extra immune support.

What Does Quercetin Do?

Quercetin takes part in normal immune function and helps sustain vascular health, with possible support for healthy inflammatory responses as part of a balanced diet. This means it fits with guidance on flavonoids for healthy ageing and cellular health.

As an antioxidant flavonoid, quercetin helps manage oxidative stress and supports cellular function and DNA integrity in normal physiological processes.
