Evidence check: Zink in the context of Darmgesundheit

Zinc is an essential trace element relevant to gut health – particularly for intestinal barrier integrity, immune function, and microbiome modulation. Studies show that zinc deficiency can impair gut barrier function and promote inflammation. However, evidence for using zinc supplementation to improve gut health in the general population is moderate at best; most data come from deficiency states or specific conditions (e.g., diarrhea). The provided context does not contain specific zinc-gut health information. Therefore, this answer is based on general scientific consensus. Evidence: human-moderate. Caveat: excessive zinc intake can be toxic and interfere with copper absorption.
