Featuring IgG 2000 CWP™ and L-Glutamine: The added benefit of the amino acid L-glutamine. IgG 2000 CWP™ is an immunoglobulin concentrate derived from colostral whey peptides. It delivers natural immunoglobulins (standardized to a minimum of 40% IgG), bioactive proteins, and growth factors. These components support immune function, healthy cytokine activity, gut barrier function, and gastrointestinal health and tissue repair. Advanced coagulation and filtration techniques make IgG 2000 CWP a unique ingredient that is superior in its bioactive composition and its purity. One serving of Gut Immune Defense provides over 2 g of IgG 2000 CWP as well as 2.5 g of L-glutamine, which is added to support intestinal mucosal barrier integrity. Gut Immune Defense is naturally flavored and tastes great, making it easy to consume.
