GlutaShield® Vanilla by Ortho Molecular Products

Frequent heartburn, a touchy stomach after NSAIDs, or loose stools after antibiotics are the real-world reasons people reach for glutamine for gut healing. The 4 g L-glutamine here fits those aiming to calm irritation and maintain the gut lining, especially if stool tests like fecal calprotectin (an inflammation signal in the gut) are normal or only mildly elevated. It’s also a fit during higher stress or travel when reflux flares. For severe inflammatory bowel disease, work with a clinician.

L-glutamine is the preferred fuel for enterocytes (the cells that line your intestine), helping them tighten junctions and maintain the barrier. Zinc bisglycinate provides zinc, a cofactor for tissue repair and immune defense in the gut. N‑acetyl‑D‑glucosamine supplies building blocks for mucin (the protective mucus layer). DGL licorice increases mucus without the blood pressure effect of regular licorice. Aloe gel polysaccharides soothe irritated tissue. Vitamin A supports epithelial integrity and secretory IgA (front‑line immune antibodies) in the gut.

Mix one scoop in water or a non-acidic beverage once daily. Take with or without food; sensitive stomachs often prefer it with a small snack. Clinical protocols for active flares often use higher total glutamine (5–15 g/day), sometimes split twice daily, so if you need a bigger push, discuss short-term up‑titration. Expect symptom changes within 1–2 weeks and steadier results by 4–8 weeks. If you track hs-CRP (a general inflammation marker), check it after 8–12 weeks.

Avoid if you have a shellfish allergy unless you confirm the N‑acetyl‑D‑glucosamine source is non‑shellfish. DGL is deglycyrrhizinated, but if you’ve had licorice‑related high blood pressure in the past, discuss with your clinician. Aloe gel extract can loosen stools in some people. Significant liver disease with prior encephalopathy (confusion from high ammonia) is a reason to avoid high‑dose glutamine. Separate zinc from quinolone or tetracycline antibiotics and levothyroxine by at least 2–4 hours to prevent absorption issues.
