Zonulin Test | Gut Permeability Marker
Uncover the hidden driver of your gut barrier dysfunction.
The Zonulin Test measures levels of zonulin, a protein that regulates the tight junctions between the cells lining your gut. Elevated zonulin is associated with increased intestinal permeability, often referred to as 'leaky gut', where the gut barrier becomes less effective at controlling what passes into the bloodstream. This test is for anyone experiencing unexplained digestive symptoms, food sensitivities, or chronic inflammation, and for those who want to investigate whether gut barrier dysfunction may be contributing to their health concerns.

Why it matters
Zonulin is currently the most studied blood marker of intestinal permeability. Higher levels have been linked to conditions such as coeliac disease, inflammatory bowel disease, irritable bowel syndrome, and autoimmune conditions. Measuring zonulin can help you and your clinician understand whether a compromised gut barrier may be playing a role in your symptoms, guiding further investigation and personalised dietary or therapeutic strategies.
