Certificates of Analysis
Every certificate we publish, lot by lot, with the analytical results readable on the page rather than locked inside a PDF. Certificates are issued by Vanguard Laboratory, accredited by the American Association for Laboratory Accreditation (A2LA accredits testing laboratories to ISO/IEC 17025), and by Kovera Labs.
Coverage, stated plainly: 21 certificates cover 23 of our 53 listings. The remaining 30 show a batch-analysis-pending marker on their product page and are not represented here. Some certificates cover more than one listing where the listings share one certificate.

Figures are transcribed from the certificates, which remain the authoritative record and are linked from each certificate page (where a PDF is a distributor's copy, its page says so and points to the lab's own verification). A2LA accreditation covers the specific methods listed on the laboratory's certificate, not every analysis a laboratory performs.
The laboratory did not observe or participate in sample selection and cannot confirm that a sample is representative of its lot. This is stated on the certificates that carry it and is standard for third-party analysis.
