1. What counts as a correction

We treat the following as correction events when they affect what users saw or how a product was interpreted:

• Unit, serving-size, calculation, data-pull, or import errors.
• Source-scope mistakes, including applying one flavor, lot, certificate, or sample to another product.
• Updated lab results, changed certificates of analysis, reformulations, recalls, or label updates.
• Copy clarifications when prior wording made evidence sound stronger than it was.
• Methodology changes that materially affect a public score, grade, or recommendation.

2. What we publish

For material corrections, the public record should include the practical information a reader needs:

• What changed.
• The corrected value, wording, scope, or score state.
• The prior public value or wording when preserving it helps users understand the correction.
• The date of the correction.
• The evidence source or reviewer basis for the change.
• Whether the product score was changed, downgraded, blocked, or left unchanged.

3. Timing and review

When a credible issue is raised, we can temporarily downgrade a product to limited evidence, insufficient evidence, or needs review while the issue is checked. Speed matters, but we do not replace one rushed claim with another rushed claim.

Corrections involving lab interpretation, contaminant exposure, safety thresholds, or nutrition scoring should be reviewed by the appropriate internal reviewer or external subject-matter reviewer before a confident public score is restored.

4. Product score receipts

Product pages can carry evidence receipts that show the source basis behind a score. When a correction affects a score receipt, the receipt should show:

• The evidence tier, such as label-only, source-backed, lab-backed, or insufficient data.
• The exact product, flavor, size, lot, sample date, and tested-scope limits when available.
• The dose context used for contaminant or exposure interpretation.
• The review status and any unresolved missing evidence.
• Correction history when the public result changed materially.

5. Brand and user challenges

Brands can submit factual challenges through the Brand Response Portal. Users can report issues through support. A challenge can correct facts, scope, or evidence, but it cannot buy a better score or special treatment.

Evidence that can change a result includes updated labels, product photos, lot information, certificates of analysis, lab reports, reformulation notices, or other verifiable source material.
