FMT Scientific Research
Microbiota transplantation is not an experimental procedure — it's a method with an extensive evidence base. Thousands of studies confirm the efficacy and safety of FMT for various conditions.
An Evidence-Based Method
Han's United conducts its own research and collaborates with Nanchang University. Our protocols are based on data from 15,000 patients and publications in leading journals.
Leading journals — New England Journal of Medicine, Nature, The Lancet — regularly publish results of FMT clinical trials. We apply only those protocols that are supported by high-quality research.
Evidence Levels
FMT efficacy varies depending on the condition. We honestly inform about the current state of research.
C. difficile
Gold standard for treating recurrent infection. FDA-approved. Per Han's United data — improvement in 85.8% of patients.
Inflammatory Bowel Disease
Active clinical trials for ulcerative colitis (64.3% improvement, 510 Han's United patients) and Crohn's disease.
Irritable Bowel Syndrome
Promising results across various IBS subtypes.
Neuropsychiatric Disorders
Autism: improvement in 75.3% of 365 Han's United patients. Research on the gut-brain connection in depression and Parkinson's.
Metabolic Disorders
Impact of the microbiome on obesity, type 2 diabetes, metabolic syndrome.
