Zonulin is a protein that plays a critical role in regulating the permeability of tight junctions in the gastrointestinal tract. By modulating these junctions, zonulin controls the flow of substances between the intestines and the bloodstream, maintaining gut barrier integrity. Abnormal levels of zonulin have been associated with a variety of conditions, including celiac disease, type 1 diabetes, and other autoimmune diseases. Understanding zonulin levels through specific blood tests can provide insights into gut health and guide strategies for managing conditions related to increased intestinal permeability.
