Certificates of Analysis
Every batch, independently tested. Nothing hidden.
We publish the Certificate of Analysis (COA) for every production batch of Gaja Labs NMN. Each report comes from an independent, ISO 17025-accredited laboratory — not from us.

Manufactured by
cGMP-certified facility, enzymatic synthesis.
Gaja Labs NMN is produced by a cGMP-certified contract manufacturer with over two decades of experience in pharmaceutical-grade nucleotide synthesis. Production runs inside an ISO Class 8 clean-room suite using enzymatic synthesis — not chemical routes — to yield the bioactive β-isomer at consistently high purity without residual heavy-metal catalysts.
Every batch is held in quarantine until both the in-house QC lab and an independent third-party laboratory release their results.
COA links are placeholders. Replace each PDF URL with the official certificate from your testing partner when available.
How to Read a COA
The four lines that actually matter.
- 01
Assay / Purity
Look for ≥ 99% by HPLC. Anything lower means the bottle contains meaningful amounts of byproducts.
- 02
Identification
Confirms the substance is β-NMN, the bioactive isomer — not the α-form or a related nucleotide.
- 03
Heavy metals
Lead, arsenic, cadmium, mercury — each should fall well under USP <232> limits.
- 04
Microbial limits
Total aerobic count, yeasts/molds, and absence of E. coli, Salmonella, and S. aureus.
