If you suffer from digestive discomfort, food intolerances, or inflammatory conditions, your gut health may be at the root. The GI-MAP with Zonulin test provides all the detailed insights of the standard GI-MAP while also measuring zonulin, a key marker of intestinal permeability ("leaky gut"). This offers a deeper look into both microbial balance and gut barrier function.

Why Need a GI-MAP Test with Zonulin?

 The addition of zonulin testing helps assess whether the intestinal barrier is compromised, a condition linked to autoimmune disease, allergies, and systemic inflammation. Identifying both microbial imbalances and intestinal permeability allows for a comprehensive approach to restoring gut integrity, improving digestion, and supporting immune health.

FAQs

What is zonulin and why is it important?

Zonulin is a protein that regulates intestinal permeability. Elevated levels suggest a “leaky gut,” allowing toxins and particles to enter the bloodstream.

How does this test differ from the standard GI-MAP?

It includes everything in the GI-MAP plus zonulin measurement, providing extra insight into gut lining health.

Who should consider the GI-MAP with Zonulin?

It is especially valuable for those with autoimmune conditions, allergies, chronic inflammation, or suspected leaky gut.

Can leaky gut be treated if detected?

Yes, with targeted nutrition, lifestyle changes, and professional support, gut barrier integrity can often be improved.

Is the sample collection the same as GI-MAP?

Yes, a stool sample is collected at home and sent to the laboratory for testing.
