What Is Leaky Gut?

Leaky gut occurs when tight junctions between intestinal cells weaken, allowing undigested food particles, bacteria, and toxins into the bloodstream — triggering autoimmune conditions, food sensitivities, brain fog, skin issues, joint pain, and fatigue.

What Causes Leaky Gut?

  • Inflammatory Foods — gluten, processed foods, excess sugar
  • Gut Infections — H. pylori, candida, parasites, SIBO
  • Medications — NSAIDs, antibiotics, PPIs, birth control
  • Chronic Stress — cortisol weakens tight junction proteins
  • Environmental Toxins — glyphosate, heavy metals

The 5R Gut Healing Protocol

  1. Remove — Trigger foods, infections, irritants
  2. Replace — Digestive enzymes, HCl, bile support
  3. Reinoculate — Targeted probiotics and prebiotic-rich foods
  4. Repair — L-glutamine, zinc carnosine, collagen, butyrate
  5. Rebalance — Nervous system support, stress management
