Third-party lab results for every lot

Updated October 2026.

Find the lot number printed on your bottle, then read what the third-party laboratory measured in that batch. Every figure on this page is transcribed from the certificate of analysis issued for that specific lot.

BatchProof is the Numi Naturals verification path, and this archive is the record behind it. A lot number printed on a bottle resolves to a certificate of analysis published for that same batch.

What is a certificate of analysis?

A certificate of analysis, or COA, is a laboratory document reporting what was measured in one specific batch of material. It names the analyte, the method, the measured result and the specification it was checked against, and it describes that lot rather than the product line or the company. That is why a COA lookup starts with a lot number instead of a brand name.

What a certificate can and can't establish, and the 7 checks worth running against any brand, are covered in the verification checklist. This page is the data.

Publishing lot-level data like this is uncommon. Of 50 best-selling saffron and NMN supplements checked on their brand websites, 3 let a shopper match a certificate to the lot on their bottle, according to the COA Gap Index.

For NMN, we also compared 5 brands' NMN certificates, line by line, our own included.

Which lots are published now?

Seven lots across 5 products. Saffron360 and NMN360 are each shipping from two lots at once, so each has two rows. Each row links to that product's full transcription and to the document itself.

The lab sample ID is the laboratory's own reference for the material it received, which is the string to quote if you contact the laboratory directly. The date shown is the date the laboratory completed testing, or for the Neurofix+Chill lot the date the report was released, because that certificate carries no per-test date column. Each certificate is issued to Vox Nutrition, the contract manufacturer that produces our formulas, and it names the lot in your bottle.

Saffron360 certificate of analysis, lot SAF250514 (PDF) · Saffron360 certificate of analysis, lot SAF250523 (PDF) · NMN360 certificate of analysis, lot NMN251218 (PDF) · NMN360 certificate of analysis, lot NMN260811 (PDF) · the other 3 documents are not yet hosted here, and we will send a copy to anyone who asks at hello@numilove.com. Nothing here is gated.

What was measured against the label?

Nine analyte results across the 7 lots are checked against a stated specification. Everything else on those certificates is a contaminant screen rather than a label check.

The Saffron360 rows are identity tests rather than quantities. FTIR compares the powder against a reference standard for Crocus sativus and reports whether it matches, so neither Saffron360 certificate states a milligram figure and no coloring-strength figure. The two NMN360 rows are the only measured doses in the archive.

What did the heavy metal screens find?

All 7 lots were screened for arsenic, cadmium, lead and mercury. No lot exceeded a stated limit. The 6 Ethos lots report against a USP limit, and the Neurofix+Chill lot reports measured concentrations with no numeric limit set against them.

LOQ is the limit of quantification, the lowest concentration a method can reliably measure, and a result below it means the analyte was not detected at a measurable level. The Ethos lots are tested by ICP-MS under USP <233>, and a figure above the LOQ, such as the 0.031 ppm lead result for Saffron360 lot SAF250514, is the concentration the laboratory measured. The Neurofix+Chill lot is tested by ARL ICPMS 8.016, whose specification column reads Record only for each metal, so that report states the measured concentration without setting a numeric limit against it.

What did the microbiological screens find?

Seven results per lot, 49 in total. Every one came in at or under its limit, and the 3 pathogens screened were not detected in any lot.

The 6 Ethos lots are screened by Petrifilm and qPCR under USP <2021> and USP <2022>, and each of those certificates also records that the sample was inspected and found free from visual mold, mildew and foreign matter. The Neurofix+Chill lot is screened under USP <2021>, USP <2022> and AOAC 991.14, and that laboratory reports none detected where growth fell below its own detection limit. The NMN360 lot NMN260811 certificate adds an Enterobacteriaceae screen and reports yeast and mold as one combined result, so its 7 rows are copied exactly as printed.

Who ran the third-party testing?

Two laboratories, and their standards wording is not the same. That difference is worth reading rather than skipping, because the phrase third-party tested covers both and doesn't distinguish between them.

Both laboratories are ISO/IEC 17025 accredited: Ethos Analytics Laboratory under accreditation number 117798, and Analytical Resource Laboratories under accreditation number 77504.

Where are the products made?

One contract manufacturer makes every lot above. Its facility holds a current certification against a manufacturing standard, which is a different kind of evidence from the certificates on this page and answers a different question.

This certifies how the facility manufactures. It is not a certification of any product we sell and not a test of any lot, and we hold no NSF product certification of our own. The certificate number is printed here so you can quote it to NSF or to the manufacturer rather than take our word for it.

What this archive does and does not establish

Check your own bottle

The lot number is printed on the bottom of the bottle. If it ends in a hyphen and more digits, such as SAF250523-60, the part before the hyphen is the lot. Find the matching row above. That takes seconds. If the code differs from every lot shown, your bottle is from a batch not listed here. Ask for that batch's certificate at hello@numilove.com or scan the code on the bottle.

BatchProof is the name for that lookup, and nothing in it is particular to this line. Want to run the same checks against any brand, ours included? The 7-step verification checklist walks through what to ask for and what a certificate can and can't prove.

See the transparency page

A laboratory issues its report to whoever submits the sample, so these certificates carry the name of Vox Nutrition, the contract manufacturer that produces our formulas. The lot number on each one is the lot in your bottle.

Vox Nutrition commissions each lot's certificate from a laboratory owned by neither company, which is what makes it an independent check rather than a self-assessment.

Sources for the standards named on this page: ISO/IEC 17025:2017, the general requirements for the competence of testing and calibration laboratories; USP general chapter 2021, microbial enumeration tests for nutritional and dietary supplements; and 21 CFR part 111, the manufacturing practice rules a dietary supplement is made under.

Almost every supplement on the shelf is made by a contract manufacturer. The difference is that most brands don't tell you which one.
