A certificate of analysis (COA) documents what is in a batch and confirms it meets specification. Here is how to read one for mineral products.
Composition and concentration
The COA lists the mineral profile and concentration, letting you confirm dosing and label claims.
Safety parameters
Heavy-metal results against recognised limits (e.g. U.S. Food Chemicals Codex) confirm the batch is safe for use.
Batch traceability
Batch and date references tie the COA to the exact lot you received, supporting your own QA records.
