What does it look like when digestive resilience begins not just with symptom relief—but with restoring balance deep within the gut ecosystem?

This month on The Microbiome Collaborative, join Thaena founder Dr. Andrea McBeth, ND, for an unscripted, clinically grounded conversation with Dr. Ilana Gurevich, ND, LAc, FABNG, exploring the realities of complex gastrointestinal care and what it truly takes to rebuild gut function when conventional approaches fall short. Together, they examine how microbiome disruption, oxidative stress, and chronic inflammation shape persistent digestive disorders—and why lasting recovery requires a deeper, root-cause perspective.

In this episode, they’ll dive into Dr. Gurevich’s systems-based approach to chronic GI conditions including IBS, chronic diarrhea and constipation, GERD, Crohn’s disease, ulcerative colitis, and persistent abdominal pain. Expect a thoughtful discussion on dysbiosis, microbial signaling, oxidative stress, and how herbal medicine, nutrition, and postbiotic pathways intersect to support digestive repair. The conversation also explores why many patients remain “stuck” despite treatment—and how restoring physiological function goes beyond simple symptom management.
