Sleep+Recover certificate of analysis
Current published lot MFP251030
This certificate measures the calcium on the label and screens the blend 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 the record, and we will send a copy to anyone who asks for it.
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 | Sleep+Recover |
| Certificate issued to | Vox Nutrition, 8224 Industry Circle, West Jordan, UT 84088, the contract manufacturer that produces this formula |
| Lot number | MFP251030 |
| Sample name on the certificate | 13105 - Melatonin Plus EXP 11/2027 |
| Laboratory sample ID | 25EA1117-008 |
| Sample type | Powder |
| Date received | 18 November 2025 |

The sample name is the manufacturer's internal formula code. It differs from the retail product name, and it is reproduced here exactly as it appears on the certificate.
What was tested?
| Analysis | Method | Date tested | Status |
|---|---|---|---|
| Calcium | ICP-MS | 24 November 2025 | Complete |
| Heavy metals | ICP-MS | 21 November 2025 | Pass |
| Microbiological | Petrifilm/qPCR | 22 November 2025 | Pass |
Did the tested ingredient meet the label?
It came in above it. Calcium measured 19.28 mg per serving against a label figure of 17 mg. Calcium is the only analyte this report checks against a label specification.
| Analyte | Result | Specification | LOQ (ppm) |
|---|---|---|---|
| Calcium | 19.28 mg per serving | 17 mg per serving | 0.1 |
Calcium is the only analyte on this report measured against a label specification, and it came in above the amount the label states.
How did it do on heavy metals?
All four passed. Arsenic, cadmium and lead were measurable and came in under specification, and mercury was below the limit of quantification.
| Analyte | Result (ppm) | LOQ (ppm) | LOD (ppm) | Limit (mcg/day) | Result |
|---|---|---|---|---|---|
| Arsenic | 0.043 | 0.010 | 0.005 | 15 | Pass |
| Cadmium | 0.041 | 0.010 | 0.005 | 5 | Pass |
| Lead | 0.215 | 0.010 | 0.005 | 5 | Pass |
| Mercury | <LOQ | 0.010 | 0.005 | 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 the pathogens tested were not detected at all.
| Organism | Result | Limit | Pass or fail |
|---|---|---|---|
| Total aerobic plate | <20 CFU/g | <100,000 CFU/g | Pass |
| Coliform | <20 CFU/g | <100 CFU/g | Pass |
| Yeast | <20 CFU/g | <1,000 CFU/g | Pass |
| Mold | <20 CFU/g | <1,000 CFU/g | Pass |
| Escherichia coli | Negative/10g | Negative/10g | Pass |
| Salmonella | Negative/10g | Negative/10g | Pass |
| Staphylococcus aureus | Negative/10g | Negative/10g | Pass |
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
- Calcium was measured at 19.28 mg per serving against a stated 17 mg, so that label figure is covered by a laboratory result.
- The lot is clean on the contaminants tested. All four heavy metals sat within their USP limits and every microbiological result passed specification.
What it does not
- It does not quantify melatonin or any other ingredient in the formula. Calcium is the only analyte on this report measured against a label specification.
- It carries no identity test. There is no reference standard comparison on this certificate, unlike the FTIR identity work on our saffron lots.
- It says nothing about what any ingredient does for anyone. That is a question for clinical research, not a laboratory certificate.
Check your own bottle
The lot number is printed on your bottle. If it reads MFP251030, this is the certificate covering what is inside it.
This page always carries the current published lot. If your bottle shows a different number, it is from a batch we have since replaced here, and you can request that batch's certificate at hello@numilove.com or scan the code on the bottle.
Get told when a new lot posts
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 Sleep+Recover 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.
