Request a Certificate of Analysis.
Lab reports and Certificates of Analysis are available on request, per product and per lot. Send us the batch number printed on your package and we will send what exists for that lot.
What's on a Certificate of Analysis (COA)
A COA documents the lab results for a specific production lot. Where a COA exists for your lot, it typically covers:
- Identity — confirmation that the active ingredient is what we label it as
- Potency — confirmation that the active ingredient is present at the labeled dose
- Heavy metals — lead, arsenic, cadmium, and mercury results, with thresholds
- Microbials — total aerobic count, yeasts, molds, E. coli, Salmonella
- Batch reference number — certificate ID for the lot
Panels vary by product and by lot. We send the document as it was issued — we do not summarise or reformat it.
How to request your COA
01
Find the batch number. It's printed on the package or bottle. For supplements it's usually under the lot/expiration line. For skincare it's on the base of the tube or bottle. The format varies by product.
02
Email support@zmzmlabs.com with the subject line "COA request." Include: the batch number, the product name, your order number if you have it, and where you'd like the COA sent.
03
We reply with the documentation that exists for that lot. If a document doesn't exist for your lot, we will tell you that plainly rather than send you something else.
What about skincare products? Topical products are formulated to halal standards and formulated for use around wudu, and lab documentation is available on the same per-lot basis. The water-permeability test described on our Lab Reports page has not been run yet, so no result for it is included.
Bulk requests, wholesale partners, journalists
If you need documentation across a range of lots (a wholesale partner stocking a shelf, a journalist verifying claims for a story, a Muslim community organization vetting brands for members), email wholesale@zmzmlabs.com or press@zmzmlabs.com and we will send what exists for the lots you name.
