Naturopathic gastroenterologist
Mark Davis, ND (FABNG), discusses his work in fecal microbiota transplantation (FMT), research, and integrative approaches to GI disease. Davis explains FMT history, screening criteria, delivery methods, how it differs from probiotics, and why it is highly effective for recurrent C. difficile (about a 90% durable cure), while noting FDA-approved products (Rebyota, Vowst) and off-label applications. He describes IRB-approved studies on naturopathic care for IBS and ulcerative colitis and a blinded project comparing consistency across 15–20 stool microbiome labs. The conversation covers evidence for diet in IBS/IBD (including SCD and a semi-vegetarian diet), low-FODMAP as a temporary tool, breath testing and relapse in SIBO, helminthic therapy options and legality, targeted probiotics (Saccharomyces boulardii, Akkermansia, soil-based species), enema therapies, indigo naturalis benefits and risks, saffron evidence for mood, telemedicine practice, and a crowdfunding platform for clinical trials.
