Why it matters

Quality and testing terms help readers ask what was actually tested, which batch was covered, and whether a claim is backed by accessible documentation.

What it does not prove

A testing, certification, facility, or manufacturing phrase does not automatically prove every claim, every batch, or the suitability of the product for a specific person.

What to check
  • Identify whether testing is identity, potency, contaminant, or finished-product testing.
  • Look for a batch-specific document and matching lot number when available.
  • Distinguish registration, certification, and approval; they are not interchangeable.
