What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and D3 provide strong evidence for supporting immune function. Quercetin and Cordyceps mycelium are associated with respiratory and immune support, though research evidence for these specific botanical extracts is more limited. Nettle extract is traditionally used for respiratory health, but clinical data is sparse.
