What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin C and citrus bioflavonoids are supported by strong evidence for supporting immune function and antioxidant activity. Rose hips provide additional vitamin C and polyphenols, though evidence for specific therapeutic outcomes is more limited. The combination is generally recognized as safe for most adults.
