About Our Research Process

SupplementChecker is a free directory of 7,882 supplement brand profiles. We are reviewing the source evidence behind the earlier dataset. Currently, 3 brands have reviewed product certification records; that does not mean their full brand reviews are complete.

What a reviewed record means

We record the primary source, inspection date, review status and exact product scope. A certification for a particular formulation, flavor, region or lot does not establish certification for every product from that brand.

A score is available only when its required certification and regulatory coverage is reviewed. Missing evidence is shown as unknown. An archived database entry or automatically generated description is not treated as a verified finding.

How the site is funded

Some retailer links are affiliate links. We may earn a commission if you buy through them. Compensation does not change an evidence score. A retailer link does not establish that every product at that destination is certified.

Limits

This site is a research aid, not individual medical advice. A certification or editorial score does not establish suitability for your health needs. Adverse-event reports do not establish causation, and missing regulatory findings do not prove a product is safe.

Profiles show source-check and review dates separately from evaluation dates. We do not promise that every record is updated daily or that this directory is a recall alert service.

Corrections and contact

Send a correction and its primary source to [email protected]. Claims require evidence review before publication.
