Figure 1: Mechanism of action of serum-derived bovine Immunoglobulin. SBI action begins with the immunoglobulin content binding to intraluminal microbial components, leading to downstream effects that include maintenance of homeostatic mucosal immune balance, management of gut barrier function with evidence of increased expression of tight junction proteins between epithelial cells, and improved small bowel mucosal nutrient absorption.
