SBI Protect is the only purified, dairy-free source of immunoglobulin G (IgG) available as a dietary supplement. Pure IgG helps to maintain a healthy intestinal immune system by binding a broad range of microbes and toxins within the gut lumen.Provides Concentrated Immunoglobulins to Enhance Mucosal ImmunityHelps Maintain Microbial BalanceSupports GI Barrier Health and IntegrityHelps Maintain Normal Inflammatory BalanceThe discovery that the gut barrier plays a key role in immune health fueled the search to strengthen it. In that search, researchers found that the binding capabilities of immunoglobulins have a positive effect on gut barrier function. Immunoglobulins bind microbes and toxins in the GI tract and eliminate them prior to immune system activation. As these unwanted triggers are removed, it resets healthy immune tolerance and builds a stronger barrier to the external environment.
