What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Zinc and quercetin are supported by moderate evidence for supporting immune function and cellular health. Elderberry and echinacea are commonly used for respiratory support, though clinical evidence for their efficacy remains limited. Copper is included to maintain mineral balance alongside zinc supplementation.
