This product is the only purified, dairy-free source of immunoglobulin G (IgG) available as a dietary supplement. Serum-derived bovine immunoglobulins (SBI) provide the highest IgG concentration available for GI and immune challenges where allergens are a significant concern. Pure IgG helps to maintain a healthy intestinal immune system by binding a broad range of microbes and toxins within the gut lumen. This product provides 1,200 mg IgG in a one-scoop serving.


  • Provides Concentrated Immunoglobulins to Enhance Mucosal Immunity
  • Helps Maintain Microbial Balance
  • Supports GI Barrier Health and Integrity
  • Helps Maintain Normal Inflammatory Balance

1 scoop (2.5 grams) in 4 ounces of water or the beverage of your choice 2 times daily or as recommended by your health care professional.

Autoimmunity is on the rise globally, and recent research demonstrates a connection between autoimmunity and intestinal permeability. The 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.1 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.

Why we Love Microbe Binder – Make it Smooth! – Reducing Herx and “Die Off”

One of the problems with doing any antimicrobial support, is that when microbes die they make a mess. Think about how messy each death is in Game of Thrones? Who has to clean all that up? In your body, when there is a mess the immune system often reacts to help clean. While this is necessary in the long-run it means many chronic microbial imbalanced people feel worse when starting any sort of antimicrobial protocol. The immunoglobulin in Microbe Binder has been shown to cling to a variety microbes and toxins and eliminate them PRIOR to the immune system activating. That is a good thing. In non-doctor words it means it helps protocols go smoother with less negative kick back.

Not only does this product help protocols go smoother, but it also helps strengthen the gut barrier and is beneficial for the immune system. If you are trying to help the gut, help the immune system, and reduce side effects then Microbe Binder can be terrific nutritional support.


SBI and GI Health

The GI tract acts as the gateway to the rest of the body, making the health of the gut barrier critical to overall health. Environmental triggers like poor diet, high stress and toxin exposure can lead to GI challenges. In practice, probiotics are a natural choice for supporting beneficial bacteria in the gut, but supplementation to eliminate unwanted microbes should also be considered. SBI has been shown to bind microbes and toxins, further enhancing microbiome balance and facilitating gut barrier strength.2,3 Broad-spectrum binding capabilities (See Table 1) demonstrate the positive influence of non- allergenic forms of immunoglobulins.1

As seen in several studies, SBI has the potential to bind many types of microbes and toxins.1 This binding and elimination decreases microbe and toxin encounters by the immune system and resets immune tolerance.2,3

SBI and Immune Health

Occasionally, the immune system becomes overactive and immune tolerance drops. When immune tolerance is lost, the checks and balances of antibody production can be affected. To reestablish immune tolerance and appropriate activation, the burden on the immune system must be reduced. Reducing the reasons to respond allows the tissue to maintain normal inflammatory balance and creates an environment for normal tissue repair and immune reconstitution.4,5, 6,7,8,11

In studies evaluating the effect of SBI on immune function, subjects showed positive outcomes in several areas, including inflammatory balance, gut barrier function and immune cell counts.7,8,9 In an open-label human clinical study, GI-challenged patients were given 2.5 g SBI twice daily. They had increased CD4+ counts in the duodenum after eight weeks, indicating a regenerative effect on the tissue and immune function in the intestines. In a large, multicenter, placebo-controlled follow- up study,8 SBI led to significant increases in peripheral CD4+ cells, when compared to placebo-controlled subjects. Findings of immune reconstitution in these patient demographics is promising for the future of establishing a healthy immune system in patients with GI and immune challenges.
