GI Guard is a formulation for GI health using the clinically validated ingredient, PepZin GI®, a proprietary form of zinc complexed with carnosine.* PepZin GI® is slowly absorbed in the stomach, where it promotes normal mucous secretion, combats free radicals, and supports stable cell membranes.* PepZin GI® thereby helps to maintain the integrity of the stomach lining and its proper immune responses to the typically harsh gastric environment.* Numerous clinical studies have demonstrated that PepZin GI® can help to support GI health and promote gastric comfort.* PepZin GI® is a registered trademark of Hamari Chemicals, Ltd.
