What a certificate of analysis proves
A COA is issued by an independent accredited laboratory, not by us, and it applies to one production batch. It reports what the lab found in the sample it tested: the compound's purity, the contaminants screened for, and the results against EU limits.
For you, that's two things. It's the document your own compliance process needs when you take on a new supplier. And it's the answer when a customer asks how you know.
-
1
Compound purity
Confirms the active is what the label says it is. Our NMN tests at >99.9% β-NMN by ¹H-NMR, with no significant impurities in the spectrum.
-
2
Elemental screening
Twenty-two elements plus mercury by ICP-MS and ICP-OES, covering contaminants and trace minerals alike.
-
3
Heavy metals
Lead, cadmium, arsenic and mercury, reported against EU maximum limits.
-
4
Pesticide residues
Screened by GC-TOF/MS and LC-MS/MS in the finished product.

Batch-specific results
Each certificate ties to the lot number printed on the bottle your customer is holding, and states its own testing scope. Not every product is tested for every parameter — the certificate tells you which.
