Is BDNF useful for Darmgesundheit?

BDNF (Brain-Derived Neurotrophic Factor) is primarily known for its role in neuronal health and plasticity. In the context of gut health, BDNF is involved in the gut-brain axis, potentially influencing motility, barrier integrity, and immune modulation. However, evidence for using BDNF as a direct marker or intervention for gut health in humans is limited to mechanistic and preclinical studies. Consumer tests for BDNF are not standard, and MyBody-X does not appear to offer such a test. While some research links low BDNF to gastrointestinal disorders like IBS, the clinical utility remains unclear. For improving gut health, established approaches like microbiome analysis, dietary changes, and stress management are more evidence-based. Therefore, BDNF is not currently useful for assessing or treating gut health in a consumer setting. Evidence: mechanistic/unclear. Caveat: Consult a gastroenterologist for gut issues.
