Saffron360 certificate of analysis
Current published lot SAF250523
This certificate confirms the powder is genuine Crocus sativus and screens it for what should not be there.

This page is our transcription of the certificate. It is not the certificate. Every figure below is copied from the report issued by Ethos Analytics Laboratory. The complete unaltered document is linked underneath, and it is the record.
The certificate states that reports may not be reproduced with alterations of any kind, so we publish it whole rather than cropping or restyling it.
Sample and lot
| Product | Saffron360 |
| Certificate issued to | Vox Nutrition, the contract manufacturer that produces this formula |
| Lot number | SAF250523 |
| Sample name on the certificate | 13051 - Saffron 88.5 |
| Laboratory sample ID | 25EA0530-006 |
| Sample type | Powder |
| Date received | 2 June 2025 |
| Date completed | 6 June 2025 |
| Serving size | Not specified on this certificate |
What was tested?
| Analysis | Method | Date tested | Status |
|---|---|---|---|
| Identity | FTIR | 6 June 2025 | Complete |
| Heavy metals | ICP-MS | 5 June 2025 | Pass |
| Microbiological | Petrifilm/qPCR | 6 June 2025 | Pass |
Is this really saffron?
Yes. The certificate records ID Confirmed, which means the FTIR identity test compared this lot against a reference standard for Crocus sativus and found it matched.
| Analyte | Result | Specification | LOQ (ppm) |
|---|---|---|---|
| Saffron | ID Confirmed. Test sample has characteristics of the standard | ID (Presence) | Not applicable |
The FTIR identity test reports presence, not quantity. No dose figure appears on this certificate.
How did it do on heavy metals?
Nothing was detected. Arsenic, cadmium, lead and mercury all came back below the limit of quantification, so the ICP-MS method could not measure any of them in this lot.
| Analyte | Result (ppm) | LOQ (ppm) | Limit (mcg/day) | Result |
|---|---|---|---|---|
| Arsenic | <LOQ | 0.010 | 15 | Pass |
| Cadmium | <LOQ | 0.010 | 5 | Pass |
| Lead | <LOQ | 0.010 | 5 | Pass |
| Mercury | <LOQ | 0.010 | 15 | Pass |
LOQ is the limit of quantification, the lowest concentration the method can reliably measure. A result below it means the analyte was not detected at a measurable level.
How did it do on microbiology?
Everything passed. Each organism screened came in at or under its limit, and E. coli, Salmonella and S. aureus were not detected at all.
| Organism | Result | Limit |
|---|---|---|
| Total aerobic plate | <20 CFU/g | <100,000 CFU/g |
| Coliform | <20 CFU/g | <100 CFU/g |
| Escherichia coli | Negative/10g | Negative/10g |
| Salmonella | Negative/10g | Negative/10g |
| Staphylococcus aureus | Negative/10g | Negative/10g |
| Yeast | <20 CFU/g | <1,000 CFU/g |
| Mold | <20 CFU/g | <1,000 CFU/g |
The certificate also records that the sample was inspected and found free from visual mold, mildew and foreign matter.
Who did the testing?
| Laboratory | Ethos Analytics Laboratory |
| Address | 3020 E Camelback Rd STE 397, Phoenix, AZ 85016 |
| Laboratory director | Noel Samsum |
| ISO/IEC 17025 accreditation number | 117798 |
| Licence number | 000026LRCND60176649 |
| Standards statement | Testing procedures, equipment calibration and maintenance are carried out to ISO/IEC 17025:2017 standards |
The certificate states conformance to ISO/IEC 17025:2017 and carries the accreditation number above. It does not name an accrediting body, so we describe testing as carried out to those standards rather than describing the laboratory as accredited.
What this certificate does and does not establish
What it establishes
- The material is genuine saffron. The FTIR identity test compares the sample against a reference standard, and this lot matched it.
- The lot is clean on the contaminants tested. All four heavy metals came back below the limit of quantification, and every microbiological result passed specification.
What it does not
- It does not quantify the 88.5mg of saffron extract in a serving. This is an identity and purity certificate, and no dose figure appears on it.
- It says nothing about what saffron does for anyone. That is a question for clinical research, not a laboratory certificate.

This page always carries the lot we are shipping now. When a new batch is tested we replace the figures above. Leave your email and we will send one message per new Saffron360 lot.
A laboratory issues its report to whoever submits the sample, so this certificate carries the name of Vox Nutrition, the contract manufacturer that produces our formulas. The lot number on it is the lot in your bottle.
They commission each lot's certificate from a laboratory owned by neither company, which is what makes it an independent check rather than a self-assessment.
Almost every supplement on the shelf is made by a contract manufacturer. The difference is that most brands do not tell you which one.
