Zonulin (pre-Haptoglobin 2) is a protein that modulates the permeability of tight junctions between cells of the digestive tract wall. Once triggered, Zonulin plays an important role in the creation of what we think of as gut “leakiness.” Histamine is an important regulator of gut function and plays a key role in the body’s inflammatory processes. Diamine Oxidase (DAO) is one of the primary ways our body makes sure that Histamine levels stay in check.
