Summary
Remarkably, classic Psychedelics, including Psilocybin, appear to bidirectionally interact with the Gut Microbiome. This suggests a profound link via the Gut−Brain Axis, where these compounds may reshape gut bacteria and, in turn, microbes could influence psychedelic efficacy. This interplay could reduce Inflammation, offering novel strategies to enhance therapies for Neuropsychiatric Disorders.
Abstract
Classic psychedelics and the gut microbiome interact bidirectionally through mechanisms involving 5-HT2A receptor signaling, neuroplasticity, and microbial metabolism. This viewpoint highlights how psychedelics may reshape microbiota and how microbes influence psychedelic efficacy, proposing microbiome-informed strategies─such as probiotics or dietary interventions─to personalize and enhance psychedelic-based mental health therapies.
