Antioxidant and Immune Support
Quercetin-Bromelain Complex is a unique formulation of quercetin, buffered vitamin C, and bromelain. Quercetin is a bioflavonoid that has antioxidant activity to support vascular and immune cell function. 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.
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.
| Serving Size: | Amount/Serving |
| Vitamin C (as magnesium ascorbate/ascorbic acid complex) | 200 mg |
| Magnesium (as magnesium ascorbate) | 13 mg |
| Quercetin | 333 mg |
| Bromelain | 240 m.c.u |
Other Ingredients: Cellulose, stearic acid, vegetable stearate, silica, and ethylcellulose.
As a dietary supplement, adults take 1 to 3 tablets daily between meals or as directed by your healthcare professional.
Warning: If you are pregnant or lactating, have any health condition, or are taking any medication, consult your health professional before use. Keep out of reach of children.
Storage: Store in a cool, dry place, away from direct light.
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 the gastrointestinal tract from toxic free radical damage.
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 gastric support. Lastly, quercetin also supports the normal immune response to antigens. Quercetin inhibits the IgE-mediated release from mast cells as well as IgG-mediated histamine release.
Bromelain is a supportive enzyme in 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 immune response. Quercetin and bromelain are dietary nutrients that help support the immune system. As a potent antioxidant, vitamin C has been added to the formula for its protective role in immune cells against free radical damage especially during acute immune reactions and stress.
