Which people actually benefit?
Subgroup effects hide in average null trials. Better stratification is the next paper, not a slogan.
Darker cells mean a higher score for this topic on that metric.

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.
The field is moving from 'a lactobacillus' to defined mixes with drug-style evidence. Most shelf products will not make that jump.
Personalisation claims run ahead of trials. This atlas stays sceptical on purpose.
Open questions
Can consortia beat single strains?
Defined mixes are in trials. Complexity raises manufacturing risk.
How should labels be policed?
Strain IDs, viable counts at expiry and banned disease claims are the boring essentials.
Do they permanently change the microbiome?
Usually no. Transient detection is the common finding.
What about next-gen engineered strains?
Research exists. This atlas will not discuss construction or release methods.
The frontier is better evidence, not a home-culture kit.
