The magnesium document.
One of four.
Night Work, magnesium glycinate. On 2 September 2026 our manufacturer replaced the document held for this product. The replacement is the right ingredient — magnesium glycinate — and it is a microbiological test and nothing else. One axis carries a measured result. The other three carry no result at all: heavy metals are printed Not Tested on every analyte, and there is no identity section and no potency section on the page. The sample is a raw-material powder lot, MGL260212, tested for Vox Nutrition — not a TARE capsule and not a TARE fill lot. That is the whole of it, and the mark went from three to one the day we read it.
Lot Mark 1 / 4 Tested 2026-03-09 · Ethos Analytics · microbiology only · lot MGL260212
| Axis | State | Figure, with its opponent | Margin | Method |
|---|---|---|---|---|
| Identity | NOT RUN | No identity section of any kind on this document, and no row anywhere on it that would answer the question. Nothing here confirms the powder is magnesium glycinate rather than oxide, citrate or a buffered blend — and glycinate is what our label names. | — | — |
| Heavy metals | NOT RUN | The Heavy Metal Analysis (USP <233>) table is printed, with arsenic, cadmium, lead and mercury on it — and the Result column reads “Not Tested” on all four, with a dash under Pass/Fail. The LOQ, LOD and Limit figures printed beside them are the method’s floors and the acceptance limit. None of them is a measurement and none is presented here as one. | — | — |
| Microbiology | MEASURED | Microbiological Analysis (USP <2021>, USP <2022>), seven organisms, all pass. Total aerobic plate, coliform, yeast and mould each <20 CFU/g against limits of 100,000 / 100 / 1,000 / 1,000 CFU/g. E. coli, salmonella and staphylococcus aureus each negative per 10 g against a limit of negative per 10 g. Status on the summary row: Pass. | No margin: every result is a less-than bound rather than a quantity, so a ratio would be arithmetic on two ceilings | Petrifilm/qPCR |
| Potency | NOT RUN | No label claim profile, no assay, no elemental-magnesium result — the section does not exist on this document, and Serving Size is printed “N/A” under the sample photograph. The 275 mg on our label is a label figure and this certificate does not test it. | — | — |
- Chain
- Ethos Analytics, Phoenix AZ — the same independent laboratory that ran the creatine. Signed Noel Samsum, Laboratory Director, 9 March 2026. The licence and accreditation numbers printed in this document’s footer have now been read off and they match the creatine certificate’s; we did not assume that and we did not copy them across, we read both. They are printed in full in the caption under the certificate on /testing rather than here, because an accreditation acronym in a badge is precisely the shorthand this page refuses.
- Count
- The numerator counts axes that carry a measured result with a method beside them. On this document exactly one does. The heavy-metal rows exist as rows — and their Result column says Not Tested, so they are a table of tests that were not performed rather than a table of results. A row without a result is not a test, and counting it as one is how a mark becomes a badge. That is 1 / 4, and it is 1 / 4 with every character on the document read.
- Arithmetic
- None is ours on this mark. No ratio, no subtraction, no derived figure — everything above is transcription or a printed absence.
- Limit
- This is the lot on the document, and the lot on the document is a sealed bag of raw powder. MGL260212 is the magnesium glycinate lot Vox Nutrition had tested, before anything was encapsulated. It is not a TARE fill lot and it is not the lot in your bottle.
Four questions a certificate can answer, counted. The state is a count of rows on a document — whether a result column exists for that axis, with a method printed beside it. The margin is the division or subtraction of two figures printed on the same row, and on this mark there is none: nothing here is ours, everything above is transcription or an honest blank. The token is a count of counts, and the denominator is always printed so it reads as an incompletion rather than an award. Nobody awards this and there is no body that could take it away. What each of those words means, at length.
This is the certificate. Nothing on it is cropped, marked or redacted.
Until today this page described the document and did not show it, because we had not confirmed in writing that we were allowed to reproduce it. That confirmation exists — our manufacturer granted publication in writing on 17 August 2026, having first advised against it — so the file goes up. It is reproduced whole and unaltered, which is what its own footer requires: “Reports are prohibited from being reproduced with alterations of any kind.”
What we are not doing with it. We are not printing a “measured” magnesium figure — there is none on this page to print. We are not reading the LOQ, LOD or Limit columns of the heavy-metal table as though they were results; they are the method’s floors and the acceptance limit, and the Result column beside them says Not Tested. We are not putting MGL260212 next to a TARE lot number as though the two were the same kind of thing.
What is still owed. A certificate for a finished TARE lot carrying identity, potency and heavy metals. Until one exists this mark stays at one of four, those three axes stay NOT RUN, and no magnesium figure on this site is ever called measured. That request is on the open ledger with a date on it.
Where every line
on this page came from.
One row per field: what it says, where it came from, and how a stranger checks it without taking our word for any of it. This page carries more absences than the other two — three of its four axes were never run — every one of them is named, and the reason each is empty is printed beside it rather than left to be inferred. As of 5 September 2026 none of them is empty because we had not finished reading; the document is on this page and you can count the rows yourself.
- Lot code
- MGL260212, printed on the document as Batch/Lot and legible on the sample photograph beside it. It is the raw-material powder lot, not a TARE fill lot — the bag Vox Nutrition had tested before anything was encapsulated, and the photograph on the certificate is that bag, hand-marked “Re-work 1 / Re-work 2”. We are not deriving a code from the label or from the manufacturer’s catalogue, and we are not printing this one anywhere it could be mistaken for the number on your bottle. The retired code that used to sit on this site belonged to a different bottle from a different manufacturer, and that page now says so.Source — the certificate header, field “Batch/Lot”Check it — It is in the header of the document above, top left, third line.
- Formula and servings
- Night Work — magnesium glycinate. Three capsules supplying 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate, 30 servings to the bottle, 90 capsules. Every one of those is a label figure, named as one here, and this certificate does not test any of them — it carries no potency section at all. The full panel is on The Monograph.Source — the label, confirmed in writing by our manufacturer on 27 August 2026Check it — Read the bottle. Then read the certificate above and note that no row on it names a milligram of magnesium.
- Dates and extent
- One run, one date. Received 2026-03-05, completed 2026-03-09, and the single populated summary row is dated 2026-03-09. The document is signed the same day. Manufactured: Not printed on the document.Source — the certificate header and the Summary of Results rowCheck it — The document above, and the transcription row for row.
- The four axis states
- Microbiology measured. Identity, potency and heavy metals not run — no identity section exists, no potency section exists, and the heavy-metal Result column reads Not Tested on all four analytes. That is 1 / 4, and it is 1 / 4 with every character on the document read.Source — counting rows on the certificateCheck it — The document is on this page. If a row we call measured has no result beside it, the mark is wrong and we want to be told.
- Every figure, with its specification
- Seven microbiological results, each against its own limit, transcribed in the mark above and again at the transcription. There is no measured elemental-magnesium figure on this site, because there is none on the document — not withheld, absent.Source — transcription from the certificate, and a named absence where there is noneCheck it — /testing#night-work, row for row.
- Margin
- No margin. Nothing on this mark is ours: no ratio, no subtraction, no derived figure. A margin is the arithmetic of two printed operands, and every microbiological result here is a less-than bound rather than a quantity — dividing one ceiling by another would produce a number that looks like a measurement and is not one.Source — ours would be a division or a subtraction; there is none honest to doCheck it — There is nothing to redo, which is the honest state of it rather than a modest one.
- Method
Petrifilm/qPCR, printed in the Method column of the Summary of Results, with the analysis section headedUSP <2021>, USP <2022>. That is a named technique and a numbered compendial chapter, which is more than the creatine’s metals page gives. The other three axes carry no method because they carry no test.Source — the certificate, Summary of Results and the Microbiological Analysis headingCheck it — A numbered public method can be looked up by anyone. USP <2021> and <2022> are.- Laboratory
- Ethos Analytics Laboratory, 3020 E Camelback Rd STE 397, Phoenix AZ 85016 — the same independent laboratory that ran the creatine. Signed Noel Samsum, Laboratory Director, 9 March 2026. The licence and accreditation numbers in this document’s footer have now been read off it directly, not copied across from the creatine certificate, and they turn out to be the same pair: Lic # 000026LRCND60176649, ISO/IEC 17025 Acc # 117798. We checked rather than assumed, and we are saying which we did.Source — the certificate footer, read at full resolutionCheck it — The footer of the document above, bottom left, beneath the Ethos mark.
- Customer of record
- Vox Nutrition — the header field “Customer:” names them and the footer reads “Ethos Analytics Tested for Vox Nutrition”. Not TARE, and not Rocktomic. The Vox Nutrition quality sign-off line on the document is blank. This is the same shape as the creatine certificate: the party who paid for the test is the ingredient supplier, which is normal in this trade and is exactly why the mark cannot be read as a test of our bottle.Source — the certificate header field “Customer:” and the footer attribution lineCheck it — Top left and bottom centre of the document above.
- GMP assessor, standard, expiry, scope
- Not known — open with our manufacturer. Until August 2026 this site carried facility attestation letters belonging to our former manufacturer. On the day we changed manufacturer they stopped describing anything we sell, so all four fields came off — assessor, standard, expiry and scope travel together or none of them do. No badge returns until the letter is in hand and someone has read it.Source — nothing; we hold no letter for the current facilityCheck it — Not checkable by anyone, including us. It is on the open list at /testing and it stays there until a document arrives.
- Detection and quantitation limits
- Printed, and printed beside tests that were not run. The heavy-metal table gives an LOQ and an LOD for each of the four analytes — arsenic 0.01 / 0.001, cadmium 0.003 / 0.0004, lead 0.01 / 0.001, mercury 0.005 / 0.0005 ppm — and the Result column beside them reads Not Tested. Those are the instrument’s floors, not findings, and a page that quoted them without that sentence would be publishing four numbers that look like results. The microbiological method’s own quantitation floor is not printed; the results are given as less-than 20 CFU/g, which is that floor stated as a result.Source — the certificate, LOQ and LOD columns of the heavy-metal tableCheck it — The document above, third and fourth columns of the middle table.
- What is missing on this lot
- Three of the four axes, and all three absences are the document’s rather than ours. No identity section. No potency section — no assay, no label claim profile, no elemental-magnesium result, Serving Size printed N/A. No heavy-metal results: the table is there and every Result cell says Not Tested. Nothing on this page is now blank because we have not finished reading. The certificate has been read end to end, twice, at full resolution, and it is printed above so you can do the same.Source — the absence of three sections, read off the document itselfCheck it — Count the result-bearing rows on the document above. There are seven, and all seven are microbiological.
- Whether this is your lot
- It is not. MGL260212 is a lot of raw magnesium glycinate powder that the ingredient supplier had tested before anything was encapsulated — the photograph on the certificate is the bag. Your bottle has its own code and no document we hold names it. TARE is fulfilled by a contract manufacturer and never takes possession of inventory. We do not offer per-lot traceability and we do not claim it. The day that sentence stops being true it is deleted, and not one day sooner.Source — limit 1 at /testing, and the sample photograph on the certificateCheck it — The lookup on the directory page is switched off for exactly this reason, and the note beside it says what would switch it on.
The five strings this page uses for something it does not have
NOT RUN — the test was not performed and no row of any kind exists on the document.
NOT PRINTED ON THE DOCUMENT — the document exists and omits this field.
NOT YET TRANSCRIBED — the row is on the document and we have not finished reading it. Ours to fix, listed at /testing, and never filled in from a label in the meantime.
NOT KNOWN — OPEN WITH OUR MANUFACTURER — we have asked and have not been answered.
NOT HELD — we hold no certificate for that lot at all. That is the answer the lookup would return for nearly every code printed on a bottle, which is why it is switched off rather than shipped as a control that can only say no.
The one magnesium number we will state today
Night Work is the only supplemental magnesium in the range. At 275 mg of elemental magnesium a day it sits 75 mg under the 350 mg tolerable upper intake level for supplemental magnesium — that arithmetic is ours, it is 350 − 275, and both operands are printed. The 275 is a label figure and it is named as one every time it appears.
That headroom is not spare capacity we are inviting you to use. It is the room a multivitamin, a second product or a fortified drink would take up, and it is your job to count those rather than ours to assume you have none. The upper limit applies to supplements, not to magnesium from food.
What this page
cannot tell you.
Publishing a document is undone by overstating it. Four things this page does not do, written out rather than left for you to notice.
- The underlying file is now published, and that changed on 5 September 2026. Certificates in this trade routinely carry a clause requiring the issuer’s written approval before reproduction. We asked. Our manufacturer granted publication in writing on 17 August 2026 — he advised against it, and then said yes — so the document is on this page, whole and unaltered, which is what its own footer requires. The sentence that used to sit here, saying we had not confirmed we may reproduce it, was true when it was written and stopped being true three weeks later. Where that stands across all three documents.
- One of our three certificates was run by the company that makes the powder. Not this one: this document was run by an outside laboratory that had nothing to do with making the capsules — but it was commissioned by, and issued to, the ingredient supplier, and the thing it tested was a bag of powder rather than a bottle of capsules. The collagen’s was run in-house, it is our hero product, and its panel says so at the top in the same size type. A mark counts what a document measured; it does not weigh who measured it, so the column beside the mark does.
- This is the lot on the document. It is not the lot in your jar. TARE is fulfilled by a contract manufacturer and never takes possession of inventory, so we cannot connect the lot on a published document to the bottle in your hands. We do not offer per-lot traceability and we do not claim it.
- A certificate verifies contents. It does not verify effects. Nothing on this page is a claim about what any of this does for anyone.
