What role does Zink play in Darmgesundheit?

Zinc is essential for gut health, supporting intestinal barrier integrity, immune function, and anti-inflammatory responses. Zinc deficiency is associated with increased intestinal permeability and diarrheal diseases. However, the provided context does not mention zinc or gut health directly. The evidence for zinc's role comes from general nutrition and micronutrient research, not from the DNA tests described. MyBody-X tests do not assess zinc levels or genetic variants related to zinc metabolism. Consumers should be aware that genetic tests cannot determine current zinc status. If zinc deficiency is suspected, a medical blood test (e.g., serum zinc) is appropriate. Marketing claims about DNA-based gut health tests often overstate the evidence; the actual support for zinc and gut health is mechanistic and not substantiated by the context. Therefore, the evidence level is marked as unclear.
