Can Zink help with gut health?

Zinc is essential for gut health, particularly for maintaining intestinal barrier integrity and modulating immune responses. Evidence suggests adequate zinc levels can reduce inflammation in conditions like Crohn's disease and ulcerative colitis, and zinc supplementation is a standard treatment for acute diarrhea in children. However, the evidence is mixed: while some meta-analyses show benefits for gut barrier function, high-quality trials for conditions like irritable bowel syndrome or small intestinal bacterial overgrowth are lacking. Zinc deficiency should be confirmed via blood tests before supplementation. MyBody-X home tests can screen zinc status, but single readings may not reflect long-term status. Caveat: excessive zinc intake can lead to copper deficiency and disrupt gut microbiota. Overall, zinc is a supportive nutrient but not a standalone solution for gut health.
