Leaky Gut Revive Max is our most advanced formula yet. We took pharmaceutical-grade l-glutamine and a unique combination of healthful botanicals and added ImmunoLin - a powerful serum-derived bovine immunoglobulin protein isolate Serum Bovine Immunoglobulins (Sbi) that supports intestinal health and helps facilitate healthy immune function. Leaky Gut Revive Max is up to the challenge of supporting the body's natural immune defenses in the gut while helping to combat the root cause of leaky gut - resulting in reduced belly bloating, smoother digestion, a repaired gut lining, and a healthier appearance overall.
