What to watch with BDNF and Darmgesundheit?

BDNF (Brain-Derived Neurotrophic Factor) is a protein critical for neuroplasticity and neuronal survival. The gut-brain axis directly links gut health to BDNF levels: a healthy gut microbiome promotes BDNF expression via short-chain fatty acids like butyrate. Studies suggest that a fiber-rich diet, probiotics, and regular exercise can increase BDNF. Conversely, dysbiosis, chronic inflammation, or stress may lower it. MyBody-X does not directly measure BDNF, but their blood and stool tests can assess inflammatory markers and microbiome composition that indirectly relate to the gut-brain axis. However, evidence is mostly mechanistic and observational; direct clinical recommendations for boosting BDNF through gut health are not yet robust. A balanced lifestyle with exercise, sleep, and a Mediterranean diet remains the most evidence-based approach.
