Feature Summary

Inspir-Action® provides a potent combination of nutrients and botanicals to provide relief from symptoms and improve respiratory function. N-acetyl-L-cysteine (NAC) is a well-established mucolytic with the ability to break disulfide bonds, and has shown clinical benefit for individuals with COPD, bronchiectasis, and pulmonary fibrosis.1-6 NAC has also been shown to decrease symptoms of influenza-like infection, increase glutathione and sulfotransferase levels, inhibit activation of the inflammatory NF-kB pathway, and modulate immune function.7-10

Proteolytic enzymes can lower the viscosity of mucous secretions, and in a randomized trial bromelain reduced symptoms of acute sinusitis in children more effectively than a standard therapy.11 Marshmallow is widely used for cough and soothing of irritated mucous membranes, with mucilaginous and bio-adhesive effects attributed to polysaccharides extracted from the root.12 English ivy extract increases beta-2-adrenergic bronchial activity, relaxing smooth bronchial musculature and increasing surfactant factors. It has been shown to be an effective treatment for acute bronchitis and to improve lung function among asthmatic children when used in addition to standard medication.13,14 Extracts of mullein, wild cherry, and horehound similarly have a long history of use for various respiratory tract pathologies. These ingredients complement this formula with a unique combination of demulcent, emollient, expectorant, and antitussive properties to provide relief from symptoms.15

Consult a health care practitioner if symptoms persist and worsen. Do not use if you are pregnant or breastfeeding. Consult a health care practitioner prior to use if you have gastrointestinal lesions/ulcers, cystinuria, are taking anticoagulants/blood thinners, anti-inflammatory agents, antibiotics, nitroglycerin, or hypoglycemic drugs, or are having surgery. Hypersensitivity/allergy has been known to occur, in which case discontinue use. Nausea, vomiting, and diarrhea have been known to occur, in which case discontinue use and consult a health care practitioner. Keep out of the reach of children.

Drug Interactions

Although NAC may reduce nitroglycerin tolerance and improve its efficacy for unstable angina, severe headaches and hypotension may occur. Bromelain may increase the concentration of several antibiotics and should be used with caution in patients on anticoagulants. Marshmallow may have a hypoglycemic effect and should be used with caution with antidiabetic medications.
