What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and zinc have strong evidence for supporting immune function and antioxidant activity. Manganese and citrus bioflavonoids provide additional metabolic and cellular support, though evidence for the latter is more limited. This combination of micronutrients is generally recognized as safe for supplementation.
