Quick answers
Where should I start with Probiotics?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Probiotics?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Beneficial allies before English norms look universal.
Are the scores a ranking of Probiotics?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Probiotics to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Sour milk as medicine is ancient. The modern word probiotic was reshaped in the late twentieth century to mean live microbes with a benefit claim.
Regulators then asked for strain IDs and trials. Marketing did not always follow.
Timeline
A Nobel laureate links lactic microbes to longevity ideas in Paris.
Lilly and Stillwell use probiotic for substances that favour microbes — a meaning later narrowed.
Lactobacillus rhamnosus GG becomes a much-studied strain with a public code.
Live microorganisms, adequate amounts, health benefit — the sentence labels still quote.
Working-group guidelines push strain identification and safety dossiers.
The International Scientific Association for Probiotics and Prebiotics restates the 2001 core.
Cochrane-style reviews show benefit in some diarrhoea settings and uncertainty in many others.
Defined consortia enter drug-style pipelines, separate from yoghurt aisle branding.
History is also yoghurt vats, kimchi jars and pharmacy shelves.
