Quercetin-Bromelain Complex, provided by Douglas Laboratories®, is a unique formulation of quercetin,

buffered vitamin C, and bromelain. 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.

FUNCTIONS

Quercetin is a naturally occurring bioflavonoid with strong antioxidant activity. The antioxidant activity of

quercetin protects 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 body’s immune system. Secondly, quercetin prevents the depletion of glutathione from

the cells of the intestinal tract. Glutathione is a cosubstrate for antioxidant enzymes glutathione peroxidase

and glutathione reductase. By preserving the level of glutathione, quercetin protects 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 also reduces the immune

response to allergens. Quercetin inhibits the IgE-mediated allergic mediator release from mast cells as well

as IgG-mediated histamine release. Quercetin is a potent inhibitor of the lipoxygenase that metabolizes

arachidonic acid, which is the first step towards proinflammatory arachidonic acid metabolites. 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 inflammation 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 inflammation processes.

INDICATIONS

Quercetin-Bromelain Complex may be taken as a dietary supplement for those individuals who wish to

increase their intake of this important bioflavonoid, key antioxidant vitamin C, and the proteolytic enzyme

Bromelain.
