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

The crucial advantage that is attributable to Quercetin Phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to phosphatidylcholine, a key component of cell membranes. In the case of Quercetin Phytosome, quercetin is combined with sunflower-sourced phosphatidylcholine to create a phytosome complex that easily crosses the gut barrier.*

Quercetin has many beneficial effects on human health. Probably its most well-known mechanism of action involves stabilization of mast cell membranes, which helps to decrease the release of histamine.* Other benefits include cardiovascular support and protection of the gastrointestinal tract.* A number of quercetin's beneficial effects appear to be due to its antioxidant activity.* Quercetin scavenges free radicals and inhibits the oxidation of LDL cholesterol.* By itself, and when paired with vitamin C, quercetin reduces the incidence of oxidative damage to skin and nerves caused by glutathione depletion.*
