IgG Boost Capsules

The gut barrier plays a key role in immune health. To support the gut barrier, 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.

IgG Boost contains 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 tube.

IgG-Boost and GI Health

IgG-Boost has been shown to bind a broad range of microbes and toxins, further enhancing microbiome balance and facilitating gut barrier strength.

This binding and elimination decreases microbe and toxin encounters by the immune system and resets immune tolerance.

IgG-Boost and Immune Health

In studies evaluating the effect of IgG on immune function, subjects showed positive outcomes in inflammatory balance, gut barrier function, and immune cell counts.

In an open-label human clinical study, GI-challenged patients were given 2.5 mg IgG twice daily. They had increased anti-inflammatory cell messengers (CD4+ counts) in the small intestine after eight weeks, indicating a rebooting effect on the tissue and immune function in the intestines.
