Avoid eating or using strong-tasting products (like toothpaste, mouthwash, and tobacco) for 15 minutes before and after taking this medicine, as they may affect absorption.

Please consult the product packaging for accurate instructions on how to use the product.

The Active Ingredient Is: Quercetin

Quercetin is a plant-derived flavonoid that occurs naturally in many fruits and vegetables. This form is included within a proprietary HistaStop blend used in the product and is supplied in a dairy-based, mouth-dissolving tablet format.

What Does Quercetin Do?

Quercetin participates in normal bodily functions as part of a dietary flavonoid complex. The formulation also contains other ingredients that support the overall blend used in Allercetin Allergy & Sinus to address common seasonal exposure related sensations.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
