What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin C is supported by strong evidence for supporting immune function and collagen synthesis. Citrus bioflavonoids and rose hips provide additional antioxidants that may enhance the absorption of ascorbic acid. Research on the synergistic effects of these combined ingredients remains limited.
