Can Insulin help with Darmgesundheit?

The question of whether insulin can improve gut health lacks strong clinical evidence. Insulin is primarily a blood-glucose-regulating hormone used in diabetes management. Mechanistic studies suggest insulin may influence gut barrier function, inflammation, and the microbiome via insulin receptors expressed in intestinal epithelial cells. However, these effects are indirect and not validated as a therapeutic strategy for gut health in metabolically healthy individuals. No randomized controlled trials have tested insulin specifically for gut health outcomes. Furthermore, insulin is a prescription drug with significant risks, including hypoglycemia. Without a medical indication (e.g., diabetes), self-administration is dangerous and not supported by evidence. The evidence level is 'mechanistic/unclear': plausible biological pathways exist, but human data are absent. Consumers should not consider insulin a gut health supplement. Always consult a physician before using any hormone-based intervention.
