The discovery that the gut barrier affects 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.

SBI Protect® is the only purified, dairy-free source of immunoglobulin G (IgG) available as a dietary supplement.  IgG helps to preserve a healthy intestinal immune system by binding a broad ranges of microbes and toxins within the gut lumen.
