Quercetin
Designs For Health Quercetin + Nettles utilises an innovative form of quercetin known as Quercefit®, which incorporates a phospholipid base for enhanced absorption and bioavailability. Quercetin is traditionally difficult for the body to absorb. When attached to the lecithin-based phytosome, the solubility of quercetin is increased by 20 times, allowing for improved serum levels after supplementation.
Anti-inflammatory and immunomodulatory functions
Quercetin is a bioflavonoid compound that can affect immunity and inflammation by targeting leukocytes and influencing the activity of membrane proteins, enzymes and signalling molecules.
It is known for its effects as an anti-inflammatory and immunomodulator, particularly in conditions associated with mast cell, neutrophil and basophil degranulation and subsequent histamine release in both cellular and humoral immune responses.
It does this by inhibiting the activation of mast cells whilst also stabilising their membranes to inhibit degranulation and histamine release – one study shows that histamine release in nasal tissues may be reduced by between 46% and 99%.4,7 Other anti-inflammatory actions include inhibiting the release of Th-2 derived cytokines and reducing the secretion of antigen-specific IgE antibodies by B-cells. It also suppresses the production of both periostin and periostininduced eosinophil chemoattractants and nitric oxide production in the epithelial tissues of the nose and sinuses.
Furthermore, Quercetin may also reduce the expression of vasoactive intestinal polypeptide (VIP), capillary permeability and platelet aggregation.
It has also been shown to inhibit nuclear factor-kappa B and therefore the subsequent production and activity of inflammatory cytokines such as prostaglandins, leukotrienes, and nitric oxide synthase. It can also inhibit cyclooxygenase-2 enzymes and modify the function of neutrophils.
Preclinical studies have suggested that quercetin also promotes neutrophil chemotaxis and the phagocytic activity of macrophages and Natural Killer cells.
Antioxidant functions
Like other phenolic flavonoid compounds, quercetin shows potent antioxidant activity related to its catechol-type-Bring structure. Suggested mechanisms include direct free radical scavenging, metal chelation (it suppresses the generation of free radicals by heavy metals), enzyme inhibition or the stimulation of protective enzymes.
Urtica dioica (Nettle)
Nettle is arguably the most nutritive of herbs available to practitioners. It has a high quercetin content which is thought to contribute to its effects on the immune system. Preclinical studies have indicated an anti-inflammatory activity via the inhibition of interleukin-2 and interferon-gamma production as well as the lipopolysaccharide stimulation of TNF-alpha.

Designs for Health uses a special technology called Quercefit® to significantly improve the absorption of quercetin. Quercetin is known to be poorly absorbed by the body. By attaching quercetin to a lecithin-based phytosome, Quercefit® increases its solubility by 20 times, leading to much higher levels of quercetin in the bloodstream after taking the supplement . This enhanced absorption allows your body to utilize quercetin more effectively.

Designs for Health medicines that are listed on the Australian Register of Therapeutic Goods will display an AUSTL number on the label.
Listed medicines in Australia need to be manufactured according to legislated standards set out in Therapeutic Goods Order 101.
TGO101 legislation sets out minimum quality standards for medicines supplied in Australia that display an AUSTL number.
TGO101 mandates testing for:
- Impurities such as heavy metals (including lead, mercury, cadmium and arsenic), pesticides and residual solvents
- Dissolution (to ensure the capsule will dissolve once taken)
- Uniformity (to ensure that every capsule is the same)
- Final assay testing is also performed to ensure that what we have on the label is in each capsule, and microbiological testing is performed to ensure that no microbial contamination has occurred during the encapsulation and packing process.
