The Active Ingredient Is: Quercetin (Flavonoid)

Quercetin is a plant flavonoid that occurs naturally in fruits and vegetables and contributes to normal physiological function. This formula highlights quercetin as the primary active ingredient, complemented by bromelain to support the overall blend.

This combination uses quercetin with bromelain, which is derived from pineapple and supports the absorption interaction between these two ingredients.

What Does Quercetin Do?

Quercetin helps maintain normal immune and upper respiratory tract function, consistent with evidence showing immune modulation and respiratory support in related research.

Scientific discussion suggests that when combined with bromelain, there may be enhanced effects for upper respiratory wellness, in line with clinical observations. This information is based on research from recognised scientific sources.
