Organisms associated with Depression & anxiety
Species
Lower abundance correlates with depression and reduced quality-of-life scores in population studies.
Genus
Consistently depleted in depression in large cohorts (the Flemish Gut Flora Project and others).
Species
A GABA producer; lower loads correlate with depression and anxiety, but causal evidence is early.
‹ All conditions Conditions Organisms Influences Gut–brain axis The gut census Methodology Research associations, not a diagnosis. Most links between gut organisms and conditions are correlational, and studies often disagree. BiotaMD shows that uncertainty with an evidence tier on every claim, and flags popular ideas the evidence doesn’t support. Composition-by-weight figures are cell-size-corrected estimates. For symptoms, see a clinician — nothing here is medical advice.
