Lactobacillus kefiri
◐
Food-origin
Where this strain was first isolated, curated from the literature and culture-collection catalogs. It describes provenance only — not suitability, and not benefit.
How we classify this →
Lactobacillus kefiri is a species characteristic of kefir grains and fermented dairy products, where it is one of the primary lactic acid bacteria. Research indexed for this species includes in vitro studies examining anti-inflammatory activity in intestinal immune cells, antioxidant and enzyme-inhibitory activity, and apoptosis-related endpoints in cancer cell models, representing early-stage, non-clinical evidence. A 2024 animal study examined immune aging phenotypes. No strain-specific human clinical trials were identified; the evidence base is largely in vitro and observational, reflecting L. kefiri's role in fermented food ecosystems. 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 65 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 18 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 →
159 papers reference this strain in the probiotic database.
