If you have a leaky gut, it may be letting toxins into your bloodstream. SBI Protect® capsules is the only purified, dairy-free source of immunoglobulin G (IgG) available as a dietary supplement. IgG is important when you have a leaky gut because it helps maintain a healthy intestinal immune system by binding a broad range of microbes and toxins within the gut lumen. It’s these toxins that can put you at risk for developing a leaky gut. SBI Protect® provides 1,150 mg IgG in a four- capsule serving.
Autoimmunity is on the rise globally, and recent research demonstrates a connection between autoimmunity and intestinal permeability or Leaky gut. 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.
The intestinal barrier is a semipermeable structure that allows the uptake of essential nutrients and immune sensing, while being restrictive against pathogenic molecules and bacteria (10). Both structural and molecular components act together to fulfil this complex, but essential function of the gastrointestinal tract.
The gut barrier is a functional unit, organized as a multi-layer system, made up of two main components: a physical barrier surface, which prevents bacterial adhesion and regulates paracellular diffusion to the host tissues, and a deep functional barrier, that is able to discriminate between pathogens and commensal microorganisms, organizing the immune tolerance and the immune response to pathogens.
Other mechanisms, such as gastric juice and pancreatic enzymes (which both have antibacterial properties) participate in the luminal integrity of the gut barrier. From the outer layer to the inner layer, the physical barrier is composed of gut microbiota (that competes with pathogens to gain space and energy resources, processes the molecules necessary to mucosal integrity and modulates the immunological activity of deep barrier), mucus (which separates the intraluminal content from more internal layers and contains antimicrobial products and secretory IgA), epithelial cells (which form a physical and immunological barrier) and the innate and adaptive immune cells forming the gut-associated lymphoid tissue (which is responsible for antigen sampling and immune responses).
Disruption of the gut barrier has been associated with many gastrointestinal diseases, but also with extra-intestinal pathological condition, such as type 1 diabetes mellitus, allergic diseases or autism spectrum disorders. The maintenance of a healthy intestinal barrier is therefore of paramount importance in children, for both health and economic reasons.
SBI Protect 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 (dairy Free) immunoglobulins.1
As seen in several studies, SBI protect capsules 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 Protect 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.
