Is Insulin useful for Darmgesundheit?

Insulin is a hormone primarily used to regulate blood sugar in diabetes, not a supplement for gut health. While some mechanistic research suggests insulin may influence gut barrier function and the microbiome, there is no strong human evidence supporting its use for improving gut health. Consumer tests like MyBody-X (DNA or microbiome) do not assess insulin's role in gut health, and self-administering insulin is dangerous due to risk of hypoglycemia. The evidence is unclear and limited to preclinical studies. For gut health, focus on fiber, probiotics, and lifestyle changes. Always consult a healthcare professional before considering any hormonal intervention.
