IgGI Shield™

††USA Functional Medicine MDs, DOs, NDs, DCs and Nutrition Professionals surveyed in 2025 for Designs for Health.

IgGI Shield™ combines ImmunoLin® and N-acetyl-D-glucosamine (NAG) to support gut and immune health by promoting healthy intestinal barrier function, balanced immune and inflammatory responses, and the normal clearance of microbes and toxins from the gastrointestinal (GI) tract.* ImmunoLin®, a dairy-free, serum-derived bovine immunoglobulin (SBI) concentrate, is the only purified source of immunoglobulin G (IgG) available as a dietary supplement.* Immunoglobulins support optimal immune function at the gut and systemic levels.* NAG complements ImmunoLin® by helping to maintain the integrity of the GI tract’s mucosal barrier and further supporting immune health.*
