What's on a test certificate?
We say it a lot: every batch comes with a test certificate from the factory. But what's actually on that piece of paper? A look behind the label.
One certificate per batch
A batch is one production run: everything made in one go. Each batch gets its own number, which you'll also find on the packaging. The test certificate belongs to exactly that batch. It's called a Certificate of Analysis, often shortened to CoA.
What's on it
| Section | What it means |
|---|---|
| Product and batch number | Which product and which production run it's about |
| Production and best before date | When it was made and how long it's good for |
| Content | How much of the active nutrient is in each dose, measured in the lab |
| Heavy metals | Whether lead, cadmium, mercury and arsenic stay under the legal limits |
| Microbiology | Whether it's free of harmful bacteria, yeasts and moulds |
| Appearance | Colour, shape and smell, compared with how it should be |
Specification and result
A certificate always puts two columns side by side. The specification is what it should be: the limit or the target. The result is what the test actually found. If every result falls within the specification, the batch is approved.
It also lists which method was used. Looks technical, but it simply means anyone can check how the measurement was done.

Who does the testing?
The factory tests every batch and provides the certificate with it.
Why is there a batch number on my product?
So it can always be traced back to its production run. That way exactly one certificate belongs to it.
