Dietary Supplement Respiratory Support Wound Injury Gluten Free T Exclusive Quercenase is a combination of quercetin phytosome and bromelain. Bromelain is a compound of proteolytic enzymes derived from the pineapple plant. Bromelain has protein-digesting and immune-enhancing properties. Bromelain also contains constituents that help maintain the body's normal inflammatory response, and may help the absorption of quercetin. Quercetin stabilizes mast cells that store and release histamine. Quercetin appears to have many other beneficial effects on human health, including cardiovascular protection, as well as protection of the gastrointestinal tract. A number of quercetin's effects appear to be due to its antioxidant activity. Quercetin scavenges free radicals and inhibits oxidation of LDL cholesterol. By itself, and paired with vitamin C, quercetin can reduce the incidence of oxidative damage to skin and nerves caused by glutathione depletion. The advantage of 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.
