The Active Ingredient Is: Quercetin

Quercetin is a naturally occurring flavonoid with recognised antioxidant properties. This formulation pairs quercetin with a broccoli seed complex to help boost its absorption and cellular availability.

This product uses quercetin in a standard form aimed at nutritional support, and the broccoli seed complex is included to support bioavailability and overall delivery of the active compound.

What Does Quercetin Do?

Quercetin helps act as an antioxidant and supports immune health as part of a balanced diet. It's also described to have a natural antihistamine effect by influencing histamine release and inflammatory mediators, with the broccoli seed complex designed to boost the bioavailability of quercetin and its systemic activity.

Additionally, the broccoli seed complex contributes to cellular detoxification and antioxidant activity, complementing quercetin’s role in normal physiological processes.
