To confirm the purity and potency of ancient minerals like Shilajit, request a current Certificate of Analysis from an ISO 17025-accredited lab, verify your product’s lot number, and review testing for heavy metals, microbial contaminants, and active compounds. Also check for reputable quality seals, clear batch information and tamper-evident packaging, and consider sample testing if you suspect contamination.
There are several factors to consider, so see below for more important details that could impact your next steps.

Request a COA
If it's not publicly available, email the brand and ask for the latest batch report.
Cross-check the COA
Examine packaging
Compare multiple suppliers
Consider sample testing
