What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin C and zinc provide strong evidence for supporting immune function and skin health. Biotin and calcium contribute to metabolic processes and structural integrity, though evidence for specific collagen-synergy is more limited. These ingredients are generally recognized as safe for consumption.
