Quercenase is a combination of water-soluble 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 help maintain the body's normal inflammatory response, and may help the absorption of soluble quercetin.

Quercetin appears to have many 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. Quercetin also stabilizes mast cells that store and release histamine.

The flavonoid quercetin is ubiquitous in the plant community. It consists of a three-ringed structure with an oxygen molecule at the top of the middle flavonoid ring. It contains five hydroxyl (OH) groups, which gives it potent antioxidant activity. However, regular quercetin is not water soluble and is poorly absorbed from an oral dose. Thorne Research's water-soluble quercetin is more bioavailable than regular quercetin.
