Thorne Research Quercenase Product Information

Thorne Research Quercenase is a combination of quercetin 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 may help maintain the body's normal inflammatory response, and may help the absorption of quercetin.*

Quercetin appears to have many beneficial effects on human health, including support for cardiovascular health, as well as support for gastrointestinal tract problems.* 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 support the body's natural processes for reducing the incidence of oxidative damage to skin and nerves caused by glutathione depletion.* Quercetin also stabilizes mast cells that store and release histamine.*
