IgG Binding Proteins, Postbiotics, Prebiotics, and Probiotics

The human microbiome is a fundamental determinant of health, influencing metabolic, immunological, neurological, and gastrointestinal processes. This ecosystem of trillions of microorganisms supports nutrient digestion and immune function. Disruption of the gut microbiome by environmental factors, medications, changes in diet and other causes of dysbiosis can result in imbalances in health and microbiota.

Given its importance, gut microbiota has become a clinical target for support. Key strategies include prebiotics, which nourish beneficial microbes; probiotics, which introduce live beneficial strains; postbiotics, which deliver non-viable microbial products and metabolites; and the emerging category of immunoglobulin G (IgG) Binding Proteins, a new class of bioactive binding proteins inspired by natural defense established in colostrum to balance mechanisms in the gastrointestinal tract.
