What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Melatonin is supported by strong evidence for improving sleep onset, while vitamin C, D3, and zinc are moderately linked to immune function. Elderberry is often used for respiratory support, though evidence is more limited. This combination focuses on sleep regulation and immune system maintenance.
