What to watch with Zink and Darmgesundheit?

Zinc is crucial for gut health, supporting mucosal integrity, immune function, and microbiome balance. Deficiency can impair the gut barrier and promote inflammation. However, caution is needed: high doses (above 25–40 mg daily) may cause nausea, copper deficiency, and disrupt gut flora. Evidence for zinc supplementation in gut conditions like IBS or IBD is mixed – some studies show benefit for diarrhea, others no significant effect. Before supplementing, a blood test for zinc levels is advisable, as excess can be harmful. Also watch for interactions with antibiotics and copper. Overall, zinc's role is mechanistically plausible but clinical evidence for general gut health is moderate at best. Safety note: long-term high doses require monitoring.
