SBI and GI Health

SBI has been shown to bind microbes and toxins, further enhancing microbiome balance and facilitating gut barrier strength. Broad-spectrum binding capabilities demonstrate the positive influence of nonallergenic forms of immunoglobulins. As seen in several studies, SBI has the potential to bind many types of microbes and toxins. This binding and elimination decreases microbe and toxin encounters by the immune system and resets immune tolerance.

SBI and Immune Health

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. 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.
