How Zeta refreshes scores
Understand what triggers updates, how fast they roll out, and how to read the changelog.

We compare new ingredient lists from retailers or community uploads. When a single ingredient changes, the score is recalculated instantly.

If multiple users flag a concern and moderators confirm it, the verdict updates and everyone who scanned the item gets notified.

FAQ
Stay in the loop
Will I be notified when a score changes?›
Yes. You get push/email alerts for products in your history or saved lists. You can customize notification frequency in Settings → Alerts.
Can a score go up and down repeatedly?›
Yes, especially during investigations. We show the changelog with timestamps so you can see exactly why the verdict changed.
How do you prevent brands from gaming updates?›
Every change requires verifiable documentation. Our independence charter blocks paid influence, and community moderators can veto suspicious submissions.
