What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C is supported by strong evidence for immune function and antioxidant protection. Citrus bioflavonoids and rose hips provide complementary support, though research on their individual efficacy is more limited. These ingredients generally work together to enhance the bioavailability of ascorbic acid.
