Supplement Testing Evidence Index

This index shows the named public quality or testing signal found during each Supplement Explained product review. It distinguishes a visible product-level certification, public certificate, or testing statement from cases where no named public product signal was found. It does not rank brands, reproduce laboratory testing, or turn a missing public record into proof that no testing occurred.

How to read this index

  • Named public signal: the reviewed source set contained a named certification, testing statement, or public certificate route.
  • No named public signal found: our review did not identify one in the checked sources. This is not proof that the manufacturer performs no testing.
  • Review basis: explains whether the product page is label-based or includes a stronger original proof layer.
  • Checked date: follows the corresponding product page’s current modified date so stale records are visible.

54 product records. A named signal means we found a product-level certification, testing statement, or public certificate in the source set. “Not found” means no named public signal was identified during review; it does not prove that testing never occurred.

What different proof types can show

Proof typeWhat it can supportWhat it does not prove
Brand testing statementA stated process or policy at brand levelThat the exact SKU or lot passed a specific public test
Facility or GMP registrationManufacturing-system controls and inspections within a stated scopeClinical effectiveness or a clean result for every finished lot
Product certification directoryThat the named product appears in the certifier’s current programThat every other product from the brand has the same status
Lot-specific COA or reportResults and methods reported for the identified lotThat another lot or differently named SKU has identical results
Clinical studyAn outcome under the study’s population, dose, comparator, and designThat a retail product is identical to the intervention or works for everyone

Method and maintenance rules

  1. We start with the exact product page and visible Supplement Facts or label details.
  2. We look for a named certification, certifier directory, public certificate, or clearly scoped testing statement.
  3. We record the narrowest defensible label. A facility claim is not promoted to a finished-product certification.
  4. We preserve “not found” as uncertainty, not a negative accusation.
  5. When a product page is updated, its date and evidence row update together from the live WordPress record.

Limits you should not overlook

  • The index is a discovery aid, not a regulatory database or product recall system.
  • A seal can apply to a facility, process, product, batch, ingredient, sport-screening program, or another narrow scope.
  • Public certificate access can expire, move, or require a lot number printed on the bottle.
  • Testing for identity or contaminants does not prove that a supplement will deliver a health outcome.
  • Product names and sizes can look similar while using different formulas, directions, or certification status.
