Neurofix+Chill certificate of analysis
Current published lot AXP251013
This certificate screens the blend for what should not be there and quantifies two of the nutrients on the label.
This page is our transcription of the certificate. It is not the certificate. Every figure below is copied from the report issued by Analytical Resource Laboratories. The complete unaltered document is linked underneath, and it is the record.
The certificate states that it may not be reproduced except in its entirety, so we publish it whole rather than cropping or restyling it.
Sample and lot
| Product | Neurofix+Chill |
| Certificate issued to | Vox Nutrition Inc., the contract manufacturer that produces this formula |
| Lot number | AXP251013 |
| Sample description on the certificate | 13211 - Anxiety Plus |
| Laboratory sample ID | 861136 |
| Report number | 861136 |
| Date received | 16 October 2025 |
| Date released | 21 October 2025 |
| Released by | Hailee Rau |
| Serving size | 1,440 mg |
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 | Specification |
|---|---|---|
| Complete micro profile | USP <2021>, USP <2022>, AOAC 991.14 | Record only |
| Heavy metals | ARL ICPMS 8.016 | Record only |
| Calcium | ARL ICPMS 8.016 | ≥ 25 mg/g |
| Vitamin B1 (thiamin mononitrate) | Calculation ARL 2.011 | ≥ 12 mg per serving |
This laboratory reports one combined results table. It carries no per-test date column and no pass or fail column, so the only date on the report is the release date of 21 October 2025.
Did the tested ingredients meet the label?
Both did. Calcium measured 25.333 mg/g against a specification of 25 mg/g or more, and vitamin B1 measured 18.98 mg per serving against 12 mg or more. Those two are the only analytes this report checks against a label specification.
| Analyte | Result | Specification | MDL / LOQ |
|---|---|---|---|
| Calcium (Ca) | 25.333 mg/g | ≥ 25 mg/g | 0.001 |
| Vitamin B1 (thiamin mononitrate) | 18.98 mg per serving | ≥ 12 mg per serving | 0.02 |
The certificate notes that vitamin results are reported as the form of the vitamin named in the parentheses, which here is thiamin mononitrate. These two analytes are the only ones on this report measured against a label specification.
What did the heavy metal screen find?
Four measured figures, reported for the record. This laboratory reports arsenic, cadmium, mercury and lead as measured values rather than against a pass or fail line, so the numbers below are the raw results for this lot.
| Analyte | Result (ppm) | MDL / LOQ | Specification |
|---|---|---|---|
| Arsenic (As) | 0.262 | 0.001 | Record only |
| Cadmium (Cd) | 0.068 | 0.001 | Record only |
| Mercury (Hg) | 0.003 | 0.001 | Record only |
| Lead (Pb) | 0.226 | 0.001 | Record only |
The specification column on this certificate reads Record only for each metal, so the report states the measured concentration without setting a numeric limit against it.
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 | Method | Result | MDL / LOQ |
|---|---|---|---|
| Total plate count | USP <2021> | None detected | 100 CFU/g |
| Coliforms | AOAC 991.14 | None detected | 10 CFU/g |
| Escherichia coli | USP <2022> | Absent | Absent, per 10g |
| Staphylococcus aureus | USP <2022> | Absent | Absent, per 10g |
| Salmonella | USP <2022> | Absent | Absent, per 10g |
| Yeast | USP <2021> | None detected | 100 CFU/g |
| Mold | USP <2021> | None detected | 100 CFU/g |
The certificate defines the method detection limit as the minimum level of growth that can be detected with confidence, and explains that a result of none detected means any visible growth was below that limit.
Who did the testing?
| Laboratory | Analytical Resource Laboratories, a Tentamus company |
| Address | 520 South 850 East, Suite B3, Lehi, UT 84043 |
| Telephone | 801-847-7722 |
| Website | www.analyticalresource.com |
| ISO/IEC 17025 accreditation number | 77504 |
| Standards statement | Under accreditation number 77504, ARL is an ISO/IEC 17025:2017 accredited laboratory |
This certificate states its accreditation directly, so this page describes the laboratory as accredited. Our other products are tested elsewhere and their certificates use conformance wording instead, which is why those pages are worded differently.
The report also carries a QR code that resolves to the same certificate on the laboratory's own servers, which the document describes as its confirmation of validity.
What this certificate does and does not establish
What it establishes
- The lot is clean on the organisms tested. Total plate count, coliforms, yeast and mold all came back as none detected, and E. coli, Salmonella and Staphylococcus aureus were all recorded as absent.
- Two label nutrients were measured and both cleared their specifications. Calcium came in at 25.333 mg/g against a minimum of 25, and vitamin B1 at 18.98 mg per serving against a minimum of 12.
- Four heavy metals were measured and their concentrations are stated on the report rather than left unreported.
What it does not
- It does not quantify the botanical and amino acid ingredients in the formula. Calcium and vitamin B1 are the only two analytes 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 AXP251013, 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 Neurofix+Chill 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.
