is an expertly crafted, clinically formulated advanced respiratory health support supplement that has been formulated with high-quality ingredients such as the patented antiviral ingredient Quercefit® to support healthy histamine levels and reduce inflammation in the respiratory tract, and Vitamin C in a form that doesn’t irritate digestion, fights against toxins caused by air pollution or smoke, and whose absorption is boosted by a Citrus Bioflavonoid Complex. It also has a combination of Beta-Glucans with Vitamins A, C, and D for strengthening the immune system, and Nettle Leaf and (PA free) Butterbur for targeting histamine and leukotriene responses in allergic responses. Respirasyl™ has been studied and produced in a top-quality, cGMP certified and FDA licensed laboratory environment under the most rigorously professional conditions.
The positive benefits of the ingredients found in Respirasyl™ have been published by organizations and publications such as the Clinical and Experimental Allergy, Journal of Biological Regulators and Homeostatic Agents, and Planta Medica.
Approved Science® - research drives results!
Most other respiratory health and allergy relief supplements do not provide a potent 60 mg of the most absorbable quercetin in the form of the patented Quercefit® for advanced antioxidant, anti-inflammatory, anti-viral, and immunomodulating effects. Nor do they contain a powerful dose of Vitamin C as Calcium ascorbate which is easier on the stomach, combined with 1000 mcg of lung-repairing Vitamin A, 50 mg Vitamin D3, and 100 mg 1,3/1,6 Glucan for increasing resistance to infections by strengthening and modulating the immune system. Nor do they combine the clinically studied dosages of 150 mg Nettle Leaf Extract with 50 mg (PA free) Butterbur Root Extract for regulating Histamine and Leukotriene responses to allergens. Most do not contain 150 mg Citrus Bioflavonoids Complex which works synergistically with the Vitamin C and Quercetin to bolster their anti-histamine effects. Most do not contain 5 mg Bioperine® to increase nutrient absorption and expedite results. The truth is that most respiratory health supplements do not live up to their claims. Most do not have the potency needed. And most do not contain the highest quality ingredients available.
Due to extensive research, we have a firm understanding of the incredible health-optimizing properties of lung and respiratory health supplements. Based on our acquired knowledge, we have created a product that is uniquely formulated to provide a wide range of health benefits. These benefits include alleviating allergic rhinitis and mild asthma, reducing inflammation in the airways, increasing antioxidant protection against damage from free radicals, and boosting the immune system to prevent future infections.
Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality respiratory support supplement to get the very best results possible.
Enhances the functioning of the immune system to reduce upper respiratory tract infections
Supports healthy histamine levels to reduce symptoms of seasonal allergies and improve symptoms of mild asthma
Quercefit® provides anti-inflammatory, antiviral, and immunomodulating properties for an overall boost in respiratory health
Regulates the cytokine TH1/TH2 response to regulate immune response for healthy lung function
Decreases histamine and leukotriene responses to mitigate seasonal allergies
Citrus Bioflavonoids, Vitamin C, and Quercefit® provide antioxidants that fight free radicals and protect from oxidative damage
Provides essential nutrients to diminish deficiencies that can cause asthma, allergic rhinitis, and respiratory infections
Aids the lungs in repairing its tissue in order to maintain lung form and function
Cleanses and maintains bronchial airway support during mild upper respiratory tract infections
Respirasyl™ contains contains 60 mg of Quercefit® which is a patented ingredient that is 20 times more bioavailable than regular Quercetin, and is a powerful anti-inflammatory, antioxidant, and anti-viral agent that supports healthy histamine levels. The combination of 1000mcg Vitamin A, 500 mg Vitamin C, 50 mcg Vitamin D3, and 100 mg Beta Glucans, strengthens the immune system to decrease the risks of infection. The calcium ascorbate form of Vitamin C that has its absorption boosted by the anti-inflammatory Citrus Bioflavonoids Complex has been shown to protect the lungs and improve their function for diminishing conditions like COPD or Smoker’s Cough. The Vitamin C, Bioflavonoids, and Quercetin work together synergistically for powerful antiviral and antihistamine effects that help with mild asthma and upper respiratory tract infections. 150 mg Nettle Leaf Extract reduces histamine levels, while (PA free) Butterbur reduces leukotriene responses, thereby reducing allergy symptoms.
Containing the most bioavailable form of Quercetin combined with high dosages of vitamins, and clinically studied herbs like Nettle Leaf and (PA free) Butterbur Root, this unique supplement provides the ultimate formula for boosting respiratory health and strengthening your immune system. Many studies document the positive benefits of supplements, alongside a healthy lifestyle, in order to support a healthy respiratory tract.
This top-class lung and respiratory supplement provides the 4 essential elements of success - Increase, Reduce, Protect, Prevent - aiding the respiratory tract and immune system in a way that will ensure optimal health.
In terms of quality and purity of ingredients, there is nothing else on the market that comes close to Respirasyl™.
Certain deficiencies, such as a lack of sufficient Vitamin A or Vitamin D, can lead to repeated respiratory infection. By increasing essential vitamins, you decrease the possibility of unwanted conditions. Respirasyl™ provides Vitamin A which bolsters the immune system and aids in repairing damage to the lungs, while it also supplements Vitamin D which regulates inflammatory cytokines to reduce inflammation that causes allergic rhinitis and mild asthmatic symptoms.
When the immune system senses an irritant or allergen, it causes the release of histamines and leukotrienes. This increase in histamine and leukotriene causes inflammation and symptoms typically associated with seasonal allergy. When the lungs are inflamed, it can make it hard to breathe and cause chest pain. (PA free) Butterbur reduces histamine and leukotriene while Nettle Leaf contributes to the effort by blocking histamine receptors. Together, these herbs reduce the inflammation that usually occurs in response to irritants.
When the immune system is fighting an intruder, it can release free radicals. The Vitamin C, Quercefit®, and Bioflavonoids in Respirasyl™ are rich in antioxidants that “clean up” after the fight by finding and destroying free radicals that could cause cell and tissue damage. Together, the immune system and antioxidants protect the respiratory tract from infections.
In addition to decreasing the severity of allergic reactions, asthma, and respiratory infections, Respirasyl™ aims to prevent these conditions from occurring in the first place. By improving lung health through cellular repair and supporting healthy immune function, Respirasyl™ reduces the risk of future infections and flare-ups of allergic rhinitis and asthma caused by inflammation.
