Quality testing can support label trust, but it does not prove a supplement will deliver a health outcome.
Why this matters
Supplement content often blends very different evidence signals: human trials, animal work, mechanism explanations, label testing, and brand claims. Those signals should not carry the same decision weight.
Third-party testing can make a label more trustworthy, but it does not prove the promised health outcome. Human outcome evidence, dose match, population match, and safety context still matter.
