What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamins A, C, E, and zinc are supported by strong evidence for maintaining immune function and antioxidant defense. Arabinogalactans have limited research regarding their role as prebiotic immune modulators. Overall, the evidence coverage for this specific combination is very low.
