Zonulin Test Kit

Zonulin is a protein that is synthesized in intestinal cells and liver cells. It is a key biomarker for intestinal permeability and is the only regulator of intestinal permeability that is reversible. Zonulin is one of three ways the FIT test can diagnose a leaky gut, along with finding a sensitivity to Candida and multiple Food Sensitivities. It is estimated that anywhere between 50 and 100 percent of food intolerance sufferers have increased intestinal permeability.

Increased intestinal permeability can be caused by food allergies and sensitivities, stress, infections, and low stomach acid, among other causes. Elevated levels of Zonulin are associated with Celiac Disease, Autoimmune disease, and Multiple Sclerosis, in addition to other chronic illnesses.

In a healthy gut, there are healthy cell junctions and good nutrient absorption. In a leaky gut, however, the Villi are damaged, there is poor absorption and the cell junctions are loose. This means that bacteria and unwanted items can pass through the gut, as seen in the picture.

Zonulin Test Kit Must Be Purchased In Conjunction With The Booking A Service With A Practitioner to Read Test Results. Once service booking is verified, we will notify you and have the test shipped.
