What are the best supplements for intestinal permeability (leaky gut)?

Research suggests that L-glutamine, zinc carnosine, bovine colostrum, and butyrate may help support intestinal barrier integrity. L-glutamine is the primary fuel for enterocytes and has shown promise in reducing intestinal permeability in clinical studies. Zinc carnosine has been studied for its protective effects on the gastric and intestinal lining. Vitamin D and probiotics may also support barrier function.

Can supplements alone manage intestinal permeability?

Addressing intestinal permeability typically requires a comprehensive approach that includes identifying and removing triggers (such as food sensitivities, excessive alcohol, NSAIDs, or chronic stress), supporting the microbiome, and providing nutrients for intestinal repair. Supplements can play an important role in this process, but they work best as part of an overall strategy that addresses the root causes of barrier disruption.

When should I see a doctor about intestinal permeability concerns?

Consult a healthcare provider if you have symptoms that may be associated with impaired gut barrier function, such as persistent digestive discomfort, food sensitivities, fatigue, joint pain, or skin conditions that do not respond to standard treatments. While "leaky gut" is recognized in research, clinical testing and treatment approaches are still evolving. A qualified practitioner can help determine if intestinal permeability is contributing to your symptoms.

Associated with systemic inflammation and implicated in autoimmune and metabolic diseases.

Common Symptoms

Risk Factors

Chronic stress
Alcohol
NSAIDs
Processed food diet
Gut dysbiosis
