What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C is supported by strong evidence for antioxidant support and immune function. The inclusion of citrus bioflavonoids, rose hips, and rutin provides complementary botanical compounds, though clinical evidence for their synergistic effect on absorption is limited. This formulation maintains a high safety profile for general use.
