What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin C and zinc have strong evidence for supporting immune function, while manganese serves as a cofactor for various enzymes. Bromelain and papain are proteolytic enzymes with moderate evidence for aiding digestion and reducing inflammation. Overall, the ingredient profile is supported by established research, though evidence coverage for this specific formulation is limited.
