What the Evidence Says

AI-generated · Qwen 3.6 · methodology

This formula combines Vitamin C, Quercetin, and Nettle leaf, which have moderate evidence for supporting respiratory health and managing allergic responses. Bromelain and N-Acetyl Cysteine are included to support mucus clearance and inflammatory pathways. Research on these specific combinations is limited, though the individual components are generally well-tolerated.
