Quercetin Phytosome (QuerceFit®)

PRIMARY FUNCTION

Highly bioavailable antioxidant and anti-inflammatory flavonoid supporting immune, respiratory, and allergy health.

HOW IT SUPPORTS PET HEALTH

Quercetin Phytosome (QuerceFit®) is a patented formulation that combines quercetin, a potent plant flavonoid, with sunflower-derived phospholipids to dramatically enhance absorption and bioavailability. Quercetin is known for its powerful antioxidant, anti-inflammatory, and immunomodulatory properties. In pets, QuerceFit® helps manage allergies, supports healthy immune responses, and protects against oxidative stress. Its improved absorption means pets receive greater benefits at lower dosages, making it especially effective for dogs and cats with seasonal allergies, respiratory issues, or inflammatory conditions.

FUNCTIONAL OVERVIEW

Quercetin works by stabilizing mast cells, thereby reducing histamine release and lessening allergy symptoms such as itching, sneezing, and inflammation. As an antioxidant, it neutralizes free radicals and supports cellular health. The phytosome technology in QuerceFit® increases quercetin’s bioavailability by up to 20-fold compared to standard quercetin, ensuring efficient delivery and effectiveness throughout the body.
