Yogurt aisle
Live and active cultures is grocery English. It is not automatically a probiotic health claim.
Darker cells mean a higher score for this topic on that metric.

Quick facts
2001 FAO/WHO — live, adequate dose, benefitWorking definition
Effects are strain-specificKey rule
Lactobacillus rhamnosus GG (1985 isolate)Famous strain example
S. thermophilus + L. delbrueckii subsp. bulgaricusYoghurt pair
Usually transient, not permanentColonisation
A few strains versus thousands in the gutNot a microbiome
Probiotics are live microbes taken in a claimed adequate dose for a health benefit. The 2001 FAO/WHO sentence still rules honest labels. Strain codes matter more than aisle adjectives.
A capsule is a handful of guests, not the gut microbiome. Yoghurt and kimchi are foods first. Effects, when real, are usually transient.
This atlas is not a shopping list and not medical advice. Some trial uses exist; many banners do not. Vulnerable patients should ask a clinician before live products.

A labelled claim
English law treats probiotic as a marketing and evidence word. Kimchi in a fridge is food; a numbered strain on a box is a product story.
Strain names
Lactobacillus in ads is a genus, not a passport. Evidence is strain-specific.
Public-health desks
Public advice: ask a clinician before capsules if you are immunocompromised. This atlas is not that consult.

Frequently asked questions
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.
Can I cite these scores externally?
Treat them as atlas orientation, not certificates or forecasts.
What should I check before acting?
Primary desks for Beneficial allies: public-health desks and lab teaching frames.
