What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C is supported by strong evidence for its role in immune function and antioxidant protection. Citrus bioflavonoids and rose hips are often included to potentially enhance absorption, though research on their individual efficacy is more limited. This combination is generally considered safe for most users.
