5 Overview
'Third-Party Lab Tested' means a manufacturer sent their product to an external laboratory for testing. While better than no testing, this claim has significant limitations: there is no standard for what was tested (identity? potency? contaminants? all three?), no requirement for which lab or its accreditation, and no ongoing surveillance. The term is unregulated [1].
