🎯 What is L-Glutamine?
L-Glutamine is the most abundant amino acid in your body and the primary fuel source for intestinal cells. Your gut lining cells (enterocytes) use glutamine for energy, repair, and regeneration. Without enough glutamine, your gut can't heal itself!
💡 How L-Glutamine Heals Leaky Gut
Leaky gut (intestinal permeability) occurs when tight junctions between gut cells loosen, allowing toxins and undigested food into your bloodstream. L-Glutamine:
✅ Repairs damaged intestinal cells
✅ Strengthens tight junctions
✅ Reduces inflammation
✅ Supports gut barrier function
Studies show glutamine reduces intestinal permeability by 40-50% in just 4 weeks! 🌿
