GLR-6
Gut Defense. Mucosal Repair. Total Relief.
Gut Lining Repair Formula
Soothe. Protect. Rebuild.
Give your GI tract the support it deserves—from tip to tail.
Your Gut’s Natural Barrier
Your entire digestive system is lined with a mucosal membrane—a vital shield that protects and repairs itself faster than most tissues in the body.
But in the face of chronic inflammation, poor diet, or digestive disorders, that lining can become damaged, thin, or ulcerated.
Powered by Nature’s Most Soothing Ingredients:
L-Glutamine
The #1 fuel source for intestinal cells—crucial for rebuilding and repair.
N-Acetyl Glucosamine (N-A-G)
Supports glycosaminoglycan production—a key component of your mucosal barrier.
Slippery Elm
Gently coats and calms the GI tract, reducing irritation and inflammation.
Marshmallow Root
Forms a soothing, gel-like film to protect the lining of your stomach and intestines.
DGL Licorice Root
Speeds up repair of damaged tissue while aiding digestion—without raising blood pressure.
Fenugreek
Provides a natural protective shield to help defend and rebuild your gut lining.
Why It Works:
- Helps restore your gut’s natural defense system
- Soothes digestive discomfort
- Reduces inflammation and irritation
- Supports faster healing of the GI tract
