Lactobacillus johnsonii BS15 is a lactic acid bacterium studied primarily in animal models for its potential effects on gut-brain interactions and intestinal immunity. Research has examined the strain's mechanisms related to gut microbiota composition and intestinal permeability, with animal studies examining cognitive function and immune markers. The strain's human efficacy remains unestablished, as published research is limited to animal and mechanistic models. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
Where it's been studied Tags come from a conservative keyword scan of each paper's title, abstract, and summary. A tag is research coverage, not measured effect. How we classify this →
Share of this strain's 22 body-system-tagged papers that concern each system. Research coverage, not measured effect.
Symptoms in the research A tag means the paper's text names the symptom or condition — research coverage, not evidence of benefit. How we classify this →
Share of this strain's 3 symptom-tagged papers that mention each symptom or condition. Research coverage, not evidence of benefit.
Research Study-type filters use AI-classified labels, audited but not guaranteed — check the paper itself before leaning on one. How we classify this →
26 papers reference this strain in the probiotic database.
Match confidence
