Thorne Quercetin Phytosome 250mg - Enhanced Bioavailability Formula

Seasonal Allergy & Respiratory Support: Quercetin's primary mechanism involves stabilizing mast cell membranes, which moderates the release of histamine—the compound responsible for allergic responses. This phytosome formula provides targeted nutritional support for individuals experiencing seasonal allergies, helping maintain comfortable breathing and reducing occasional allergy symptoms through natural histamine regulation and immune cell modulation.

Superior Bioavailability Through Phytosome Technology: Unlike standard quercetin characterized by poor intestinal absorption, Thorne's exclusive phytosome complex binds quercetin to phospholipids derived from sunflower lecithin, creating a lipid-compatible structure that crosses the gut barrier efficiently. This advanced delivery system achieves up to 20 times greater bioavailability than quercetin extract alone, ensuring optimal blood levels and therapeutic benefits from each 250mg capsule.

Cardiovascular & Metabolic Support: As a potent flavonoid antioxidant, quercetin protects LDL cholesterol from oxidation—a critical factor in maintaining healthy blood vessels and cardiovascular function. This compound supports endothelial health, promotes balanced blood pressure levels already within normal range, and contributes to metabolic wellness by supporting healthy cellular energy production and protecting against oxidative damage throughout the cardiovascular system.

Cellular Protection & Healthy Aging: Quercetin functions as a powerful free radical scavenger, neutralizing reactive oxygen species that contribute to accelerated cellular aging and oxidative stress. By supporting glutathione levels and activating antioxidant enzymes, this formula helps protect cellular DNA, proteins, and lipid membranes from oxidative damage. The enhanced absorption of the phytosome form ensures quercetin reaches tissues throughout the body to support longevity pathways and maintain youthful cellular function.
