Zinc is an essential trace mineral with major roles in:
– Immune system function
– Cell growth and repair
– Enzyme activity (over 300 enzymes depend on zinc)
– Intestinal mucosa regeneration
– Water and electrolyte absorption in intestines
– Anti-inflammatory and antioxidant protection
In diarrhea, zinc:
– Improves absorption of water and electrolytes
– Enhances intestinal epithelial regeneration
– Increases brush border enzyme activity
– Strengthens immune defense for better pathogen clearance
– Reduces duration, severity, and recurrence of diarrhea episodes
