Benefits
Immune Support, Respiratory Support
Quercetin's best known mechanism of action involves its ability to stabilize mast cell membranes, which in turns can decrease the release of histamine.* In this way it provides nutritional support for individuals who occasionally suffer from allergies.* Other benefits include its cardiovascular support and protection of the gastrointestinal tract.* A number of quercetin's beneficial effects appear to be due to its antioxidant activity.* Quercetin can scavenge free radicals and inhibit the oxidation of LDL cholesterol.* By itself, and when paired with vitamin C, quercetin can reduce the incidence of oxidative damage to skin and nerves caused by glutathione depletion.* This exclusive Thorne formula features quercetin bound to sunflower-sourced phospholipids to enhance its absorption.*

Widely found in the plant kingdom, quercetin is the most abundant of the flavonoid molecules. It is found in numerous foods, including apples, onions, teas, berries, vegetables of the cabbage family, seeds, and nuts.

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.*
