ISO/IEC 17025

ISO/IEC 17025 defines whether a laboratory can be trusted.

It is an international standard that evaluates the competence of testing and calibration labs —
how measurements are performed, validated, and controlled.

Unlike product certifications, it does not apply to supplements directly.
It applies to the systems that generate the data about them.

At a high level, ISO/IEC 17025 centers on four signals:

• Method validation — whether testing methods are appropriate, validated, and fit for purpose
• Measurement accuracy and precision — whether results are consistent, reproducible, and within defined uncertainty
• Quality management systems — whether procedures, controls, and documentation are properly maintained
• Personnel and equipment competence — whether staff are trained and instruments are calibrated and verified

ISO/IEC 17025 establishes confidence in the testing process.

It does not evaluate what is being tested.

A product tested in an accredited lab may still be poorly formulated.
A meaningful formulation tested with unreliable methods may produce misleading results.

The standard defines trust in measurement.
It does not define value in the product.
