Zonulin Stool Test: Unlock Your Gut Permeability—What It Means for Your Health

A zonulin stool test is a targeted way to gauge gut permeability by measuring the levels of zonulin in a stool sample. Zonulin is a regulator of the tight junctions between gut cells, and higher levels can indicate a more permeable gut barrier, sometimes referred to as “leaky gut.” While a zonulin stool test isn’t a stand-alone diagnosis, it can provide important context about how well your gut barrier is functioning and how it may be interacting with inflammation, immune responses, and overall health. Interpreting the results alongside other gut health data helps you identify practical steps to support balance and resilience in your digestive system. InnerBuddies brings a distinctive edge to analyzing zonulin stool test results through its white-label Gut Health Operating System. This modular platform powers a wide range of gut microbiome testing products and offers features like a Gut Microbiome Health Index (a 0–100 score based on proprietary insights from an exclusive collaboration with EAFIT University in Colombia), detailed Bacteria abundances that compare your top 40 bacteria to a healthy cohort, and labeled Bacteria functions that show how your gut’s metabolic activity stacks up against healthy norms. A growing focus on Target Group analysis means you can see how your gut microbiome—and pathways relevant to specific groups such as Healthy Aging or Endurance Sport—align with your wellness goals. For a closer look at the testing options, you can explore the InnerBuddies microbiome test. Beyond that, InnerBuddies translates zonulin stool test insights into concrete, personalized guidance.
