What is XYMOGEN Quercetin 20x Plus?

Individuals with hypersensitive immune reactions often experience physical, mental, and functional decline, even with a moderate onset of discomfort. XYMOGEN Quercetin 20x Plus provides fast-acting, natural support for hypersensitivity reactions, including watery, itchy eyes and runny nose, as well as other manifestations of histamine release. Formulated with a synergistic combination of vitamins, bioflavonoids, amino acids, herbs, and bromelain, Quercetin 20x Plus addresses the distressing signs of immune hypersensitivity.  Quercetin 20× Plus combines research-based and traditional ingredients with antioxidants to robustly support the respiratory system and its organs, including nasal passages, through complementary mechanisms of action.


How does XYMOGEN Quercetin 20X Plus compare to AllerDHQ?

All of the immune and antioxidant support of AllerDHQ is now upgraded with Quercefit® for enhanced quercetin absorption. Quercetin 20x Plus for respiratory support and nasal comfort still features nettle extract, vitamin C, and NAC.

The added power of Quercefit® offers:

  • Innovative Phytosome technology, a next-gen vesicular delivery system
  • Quercetin Phytosome, which is 20 times better absorbed than conventional quercetin
  • Superior bioavailability, meaning improved efficacy with lower dose loads


What are the benefits?

  • Provides Respiratory Support
  • Promotes Nasal Comfort
  • Provides Antioxidant Support


What is in Quercetin 20x Plus?

Quercetin Phytosome (Quercefit®) Quercetin belongs to the flavonoid class of polyphenols and is found naturally in various medicinal plants as well as foods and drinks, including onions, apples, berries, brassica vegetables, nuts, wine, and black tea.  The body of scientific evidence demonstrates that ingesting quercetin confers a wide range of benefits to human health, which are primarily mediated through quercetin’s antioxidant activities and immunomodulatory effects.  For example, research results have shown quercetin has inhibitory effects on histamine release, eosinophil recruitment, and proinflammatory cytokine activity. Quercetin, like many other flavonoids, has relatively poor absorption in the gastrointestinal tract, causing limited bioavailability.

Vitamin C (ascorbic acid)- Vitamin C is essential to humans and must be obtained exogenously. While most mammals are able to synthesize ascorbic acid, humans lack one of the enzymes required for this process and can quickly become deficient if dietary or supplemental intake is inadequate. Stress, smoking, pollution, and temperature changes increase our requirement for vitamin C. Wellknown functions of vitamin C include antioxidant protection from damaging free radicals and the synthesis of collagen, carnitine, and neurotransmitters. Vitamin C also plays a lesser-known role in the deactivation of histamine.

N-Acetyl-L-Cysteine-  Oxidative stress and the interrelated production of inflammatory cytokines are thought to play a significant role in propagating respiratory symptoms in immune-reactive pathways. NAC has direct antioxidant activities and is a precursor to glutathione biosynthesis. Low glutathione levels are associated with oxidative stress and implicated in immune dysregulation—particularly T-cell–mediated functions. Replenishing antioxidants may be critical in normalizing immune function. NAC is also a mucolytic agent that decreases mucus viscosity and facilitates its clearance by hydrolyzing the disulfide bonds of mucus proteins.

Nettle Extract- (Urtica dioica) Nettles have been used as a natural remedy for 2,000 years, and modern scientists have been working to validate its historical use and elucidate mechanisms of action. Nettle leaves provide many active components, such as f lavonoids, phenolic compounds, organic acids, and vitamins, as well as volatile compounds like fatty acids and polysaccharides.
