GlutaShield is designed to promote the health and barrier function of the gastrointestinal (GI) lining. Its unique formula includes nutrients that support the gut mucosal epithelium. The purpose of the epithelium is to allow the digestion and absorption of dietary nutrients while keeping unwanted toxins, microbes and food particles from passing directly into the body. GlutaShield includes a high dose of L-glutamine (4 g), which serves as nutrition for the gut lining. It provides 400 mg of deglycyrrhized licorice root extract (DGL) and 75 mg of aloe vera extract, both of which protect and promote the health of the gut mucosa. N-acetyl glucosamine and zinc boost GI integrity.
