Description Quercetin Phytosome offers advanced phytosome technology for optimal absorption.* A number of quercetin's beneficial effects appear to be due to its antioxidant activity.* The crucial advantage attributable to Thorne's Quercetin Phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to phospholipids – phospholipids are key components of cell membranes. In the case of Quercetin Phytosome, the quercetin is combined with sunflower-sourced phospholipids to create a phytosome complex that can easily cross the gut barrier.* • Respiratory Support* • Foundational Ingredients Serving size: 1 Capsule Servings per container: 60 Ingredient Quantity Quercetin Phytosome 250 mg Other Ingredients: Hypromellose Capsule, Leucine, Microcrystalline Cellulose, Silicon Dioxide.
