The Active Ingredient Is: Quercetin

Quercetin is a naturally occurring flavonoid with antioxidant properties that helps support normal cellular defence mechanisms and inflammatory responses.

In this product, quercetin is presented alongside zinc, a trace element that supports immune function; together the ingredients work to support the body's natural defences and oxidative balance.

What Does Quercetin Do?

Quercetin helps scavenge free radicals and may modulate inflammatory pathways to support immune defences and cellular stress balance.

This action is complemented by zinc, which supports normal immune cell function and overall immune cues, contributing to the product’s broader support of immune health.
