Everything in Standard + Zonulin
Our most popular package — often searched as the G.I. MAP with Zonulin — includes the complete GI-MAP™ Standard panel (85+ biomarkers) plus the Zonulin add-on marker — a critical protein related to gut barrier function.
Why Add Zonulin?
Zonulin is a protein that modulates the tight junctions between intestinal epithelial cells. Measuring zonulin levels provides valuable insight into gut barrier integrity and intestinal permeability.
Adding Zonulin to your GI-MAP™ provides a direct measurement of gut barrier integrity — information that is valuable for practitioners developing protocols to support gut barrier function and optimize digestive wellness.
Who Should Choose This Package?
We recommend the GI-MAP™ + Zonulin for anyone seeking the most comprehensive gut health profile available. This package is ideal for health-conscious individuals, wellness practitioners, and anyone interested in a detailed analysis of their gut microbiome along with intestinal permeability measurement.
GI-MAP™ + Zonulin — Common Questions
Why do people search for a "G.I. MAP with Zonulin" test?
Many people searching for a G.I. MAP with Zonulin are looking for the most complete gut health profile available. Adding Zonulin to the GI-MAP™ provides a direct measurement of gut barrier integrity — critical information for anyone investigating leaky gut, autoimmune conditions, or chronic food sensitivities.
Is the GI mapping test with Zonulin worth the extra cost?
If you suspect intestinal permeability (leaky gut), have autoimmune concerns, or experience unexplained food sensitivities, the Zonulin add-on provides valuable data that the standard GI-MAP™ panel does not include. Most practitioners recommend this package for first-time testing.
