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, rutin, and hesperidin provide additional antioxidant support, though research on their individual efficacy in supplement form is more limited. Together, these ingredients target cellular health and systemic oxidative stress.
