Leaky Gut Revive® Max is our most advanced formula yet. We took pharmaceutical-grade l-glutamine and a unique combination of restorative botanicals and added ImmunoLin® - A powerful serum-derived bovine immunoglobulin protein isolate (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.
