Quercetin-Bromelain Complex

Quercetin-Bromelain Complex by Douglas Labs is a natural antioxidant supplement with quercetin, buffered vitamin C and the proteolytic enzyme bromelain. Read more about the many benefits of Quercetin in our recent article The Definitive Guide to the 7 Benefits of Quercetin.

• Quercetin is a bioflavonoid that has excellent antioxidant activity.
• Magnesium ascorbate is a buffered form of vitamin C, a key antioxidant, which synergistically supports the quercetin activity.
• Bromelain is a proteolytic enzyme purified from pineapple, which is active and stable at the acidic levels found in the stomach.

Quercetin is a naturally occurring bioflavonoid with strong antioxidant activity. The antioxidant activity of quercetin provides support for protecting the gastrointestinal tract in several ways.

First,quercetin prevents oxidation of lipids. The gastrointestinal tract has an increased exposure to oxidative stress due in part to the lowered pH. It is important to protect the lipid bilayer of the cell wall of the gastrointestinal tract because these cells serve as an important part of the bodys immune system.

Secondly, quercetin prevents the depletion of Glutathione from the cells of the intestinal tract. Glutathione is a co-substrate for antioxidant enzymes glutathione peroxidase and glutathione reductase. By preserving the level of glutathione, quercetin supports protecting metabolic activity and cellular structure of the highly vulnerable cells of gastrointestinal tract from toxic free radical damage. Vitamin C synergistically improves the ability of the quercetin to preserve glutathione.

Thirdly,quercetin increases mucus secretion from gastric cells. The mucus polysaccharide provides a protective buffer for the gastric cells from the low pH of the stomach contents. The reduced contact provides protection from gastric lesions. Quercetin provides an antispasmodic activity that prevents the uncontrolled peristaltic activity found in diarrhea. The reduced excretion of the intestinal contents provides benefit to the gastrointestinal tract by preventing the constant production of cellular protective materials.

Quercetin may provide allergy support by maintaing healthy histamine production. It works as a powerful antioxidant that is known to inhibit mast cells. Mast cells are responsible for the release of pro-inflammatory compounds during a reaction. It also may help reduce allergy symtoms by supporting healthy enzyme activity.

Thus, quercetin with the assistance of vitamin C in the gastrointestinal tract helps protect against gastric lesions that permit highly antigenic proteins, antigenic compounds and/or infective agents from passing into the body. In addition it prevents the release of components of the allergic response.

Bromelain is a supportive nutrient in helping prevent allergens from crossing the gastrointestinal tract. Bromelain assists in the breakdown of large macromolecular protein complexes. This reduces the chance that these complexes will leave the stomach untouched or in large fractions retaining their recognizable antigenic form that could pass through these gastric lesions inducing an allergenic response.

Quercetin, vitamin C and bromelain are all dietary nutrients that help support the immune system. They inhibit the absorption of substances into the body that may induce the allergic response. In addition quercetin is used by the body to help reduce the allergic immune response in the intestinal tract, possibly providing nutritional support to normal bodily processes.
