Quercetin, one of the two primary ingredients in Thorne's Quercetin Complex, stabilizes the body's mast cells, which store and release histamine, so it supports individuals who suffer from allergies.*

Quercetin appears to have many other beneficial effects on human health, including protection of the gastrointestinal tract and the cardiovascular system, where it scavenges free radicals and inhibits oxidation of LDL cholesterol.*

Thorne's Quercetin Complex combines quercetin phytosome (quercetin bound to sunflower-sourced phospholipids, which increases the body's ability to absorb the quercetin) and bromelain, a compound of protein-digesting enzymes derived from the pineapple plant.* Bromelain also has immune-enhancing properties because it contains constituents that help maintain a healthy cytokine balance.* Bromelain helps reduce bruising and swelling after an injury or surgery.*

A number of quercetin's positive effects appear to be due to its antioxidant activity.* By itself, and paired with vitamin C, quercetin can reduce the incidence of oxidative damage to the skin and nerves caused by the natural depletion of glutathione.*

The advantage of quercetin phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to a phospholipid, which are key components of every cell membrane.

Bromelain, which is a mixture of proteolytic (protein-digesting) enzymes from the pineapple plant (Ananas comosus), has been shown to promote healing and reduce temporary and minor swelling and bruising following an injury or a surgical procedure – including dental surgery.* One study of patients with bone fractures found bromelain decreased swelling.*

Bromelain exerts some of its positive effects because of its significant proteolytic activity.* Plastic surgeons have shown interest in bromelain because of its ability to increase the resorption rate of hematomas following surgery.*

NAC supplies N-acetyl-L-cysteine, a derivative of L-Cysteine, which is more stable and better absorbed than L-Cysteine. NAC functions as a potent antioxidant. As the precursor to glutathione intracellular synthesis, it is essential for the synthesis of glutathione. Glutathione is a critical component of the immune system, as it is an important intracellular water-soluble antioxidant. As part of this function, glutathione plays a vital role as the cofactor for the antioxidant enzymes glutathione peroxidase and glutathione transferase. Glutathione is also important to the liver, as the liver utilizes it for drug detoxification. As a metabolite of cysteine, NAC plays an important role in detoxification, and is hepatoprotective. NAC functions in protecting cells against oxidative stress, and contributes to important bodily reactions. As such it is a part of the defensive mechanism toward potential carcinogens, as well as against DNA damage. The role of NAC in acetaminophen toxicity is widely documented, however, NAC contributes to other protective mechanisms as well, including drug conjugation and excretion, peroxide and free radical destruction, maintenance of the redox state of NADPH-NADP, acid-base balance, and the synthesis of sulfated compounds. NAC also plays a role in the development of the central nervous system. There have been numerous studies using NAC, with COPD, particularly amongst patients who smoke. Utilizing NAC in smokers with chronic bronchitis showed a significant reduction in the number of positive bacterial cultures in these patients. {Riise GC, et al. Eur Respir J.1994 Jan; 7(1):94-101.} Another study utilizing NAC indicated potential benefits for chronic bronchitis, resulting in a significantly lower exacerbation rate in patients administered NAC, compared to placebo. {Rassmussen, JB & Glennow, C. Eur Respir J. 1988 Apr;1(4):351-5.} Since it easily passes through cellular membranes, NAC has been shown to be readily absorbed. It is also resistant to enzymatic breakdown.
