What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C is supported by strong evidence for antioxidant support and immune function. Bioflavonoids, including rutin and hesperidin, are often combined with vitamin C to potentially enhance absorption, though evidence for this synergy is more limited. Calcium is included to buffer the acidity of the ascorbic acid.
