Systema IBD is the most comprehensive approach in the world for people with Crohn's disease, ulcerative colitis, indeterminant colitis, and microscopic colitis. We address the biological mechanisms of IBD through helping individuals: 1) stop inflammation, 2) modulate the microbiome, 3) nourish the microbiome, and 4) repair the intestinal barrier. The results of the program are powerful and have been scientifically studied and published in major journals.
