Powerful Respiratory & Immune System Benefits
Healthy lung function
Supporting and maintaining lower respiratory tract health, including during the Winter months, is a distinctive benefit of N-Acetyl-L-Cysteine (NAC). Our cruelty-free NAC has been the focus of numerous clinical studies and a “go to”, lower respiratory tract health support amino acid for decades.
Sinus and allergies
Quercetin is clinically-proven to support upper airway health and breathing function. Our world-leading source is up to 20x more bioavailable compared to inferior alternatives.
6-in-1 immune support
Our ‘Science-Six’, Quercetin, NAC, Vitamins C, D3, Green Tea and Zinc , have each been shown to support different aspects of immune responses. Combined they provide unparalleled support.
Healthy inflammatory and free radical response is key for the immune system’s reinforcement against seasonal challenges. Vitamin D3 and Zinc support symptoms and duration of colds & flu.
