The most useful mistake we’ve made
Our contract manufacturer publishes a compliance page. It has a tidy summary table, and one of its columns is manufacturing-standard status. For all five of our products, that column said the same reassuring thing.
We nearly sourced a site-wide claim from it. Then somebody opened the actual documents.
Three of the five had expired. Two of the remaining certificates covered product formats that our products are not. And none of the six files was the certificate itself — every one was a letter about a certificate.
Nothing in that table was a lie. It was a summary, and summaries round off exactly the details that decide whether a claim is true. This article is the three checks that took us from “all five are covered” to “two are, with caveats,” and they work on any brand’s paperwork including ours.
Check 1 — is this the certificate, or a letter about the certificate?
Open any of our six manufacturing documents and the heading reads CERTIFICATION STATUS CONFIRMATION. The body says the original certificate of conformity — the one where an auditor assessed the manufacturing, processing, packaging and holding processes — is in our possession.
That is a supplier attesting, on its own letterhead, that a document exists somewhere. It is not that document.
This distinction is not pedantry, and here’s the concrete test of it: some retail channels ask a brand for facility registration plus the underlying standards certificate before they’ll list a supplement. A possession letter may not satisfy that request, because it isn’t the artefact being asked for. If a letter doesn’t clear a retailer’s bar, it shouldn’t clear yours.
What to ask for: the certificate itself, with the issuing body’s certificate number, so you can check it against the certifier’s own public register. NSF and UL both maintain one. A brand that can hand you a number you can independently verify is in a different category from a brand that can hand you a letter.
Check 2 — is it in date?
Every certificate has an expiration line. Read it, then look at today’s date. This sounds too obvious to be worth a paragraph, and it is the check that caught us.
Three of our products — the Energy & Cognition Drops, the Reishi Relax Gummies, and the Cordyceps Energy Gummies — are covered by a single shared NSF letter. That letter is dated June 6, 2025, and states its certification expiration date as June 6, 2026.
Which has passed. So for three of our five products, we have a document attesting that a manufacturing-standards certificate existed, and that it stopped being current before you read this sentence.
The other two are in better shape and it’s worth being specific rather than vague about it:
| Product | Issuer | Expires | Current? |
|---|---|---|---|
| Lion’s Mane Capsules | UL Solutions | December 8, 2028 | Yes |
| Mushroom Focus Strips | NSF | May 13, 2027 | Yes |
| Mushroom Focus Strips | WHO-GMP | May 28, 2028 | Yes, conditionally |
| Energy & Cognition Drops | NSF | June 6, 2026 | Expired |
| Reishi Relax Gummies | NSF | June 6, 2026 | Expired |
| Cordyceps Energy Gummies | NSF | June 6, 2026 | Expired |
We have asked our supplier for the renewed certificates. Until those arrive we do not claim GMP-certified anywhere on this site, for any product, because a brand-level attribute can only carry what its weakest document supports — and three of ours support nothing at the moment.
Note the “conditionally” on the WHO line. That letter states its own conditions plainly: the certificate remains valid until the manufacturing conditions or quality systems change, and its validity is conditioned on positive surveillance-audit results. So even an in-date certificate is a statement about a system that was audited, not a guarantee about a system today. Certificates are snapshots wearing the costume of a standing fact.
Check 3 — does the scope cover this product?
This is the check almost nobody performs, and it’s the one that produces the strangest result.
A manufacturing certificate is not issued to a company in the abstract. It’s issued for named processes and named product categories. Read that section and you will occasionally find that a perfectly valid certificate doesn’t cover the thing you’re holding.
The shared NSF letter covering our two gummies and our drops lists its Product Categories as: Capsule, Ingestible Liquid, Powder.
A gummy is not a capsule. It is not a powder. Whether it counts as an ingestible liquid is, charitably, a stretch. So even setting the expiry aside, that certificate’s scope may simply not extend to two of the three products it was offered for. We have raised this with the supplier as an open question and we have not had it resolved, so we are not going to resolve it here in our own favour.
Compare with the two that work:
- The UL certificate for our capsules covers the manufacturing and packaging of dietary supplement powder, tablet and capsule products. Our Lion’s Mane is a capsule. In scope, cleanly.
- The NSF certificate for our Focus Strips lists its category as Oral, Dissolving Films. Our Focus Strips are an oral dissolving film. In scope, cleanly — and this letter is the newest of the six, issued May 22, 2026, against the 2024 revision of the standard rather than the 2021 one the others cite.
The pattern worth taking away: scope mismatches happen because a supplier with many manufacturing lines holds a handful of certificates and maps them to a large catalogue. The mapping is done by people, in a spreadsheet, and it is not audited by the certifier. So the table can say “covered” while the certificate says “capsules” and the product is a gummy.
Why a bare standards claim tells you so little anyway
Even a current, in-scope, genuine certificate is a statement about process, not about the bottle. It means an auditor visited a facility and found documented procedures for cleaning, record-keeping, identity testing, and batch control. That is genuinely worth having. It is not the same as anyone having tested your batch.
Manufacturing standards and batch testing are separate axes, and a brand can be strong on one and empty on the other:
- Certificate, no testing. Good procedures, no idea what’s in your specific bottle.
- Testing, no certificate. A result for your batch, from a facility with unknown controls.
- Both. What you actually want.
- Neither. A photograph of a mushroom and a nice font.
Which is why this article is a companion to what a Certificate of Analysis actually is, not a replacement for it. The certificate is about the kitchen. The COA is about the meal.
The claim we make instead
Here is the whole of what we say about our manufacturing, and it is deliberately unimpressive:
Our products are made in an FDA-registered facility. That is true for all five and it is a much smaller statement than it sounds — registration is not approval, and it is not testing.
We do not claim GMP Facility, GMP-compliant, or any variation of it as a brand attribute. Two of five products have a current, in-scope certificate. Three do not. A site-wide badge would be reporting the table instead of the documents, which is precisely the error this page exists to describe.
When the renewed certificates arrive, this page gets updated with the new dates — including if they arrive with a scope that still doesn’t cover the gummies.
Three questions for any brand
- Is this the certificate or a letter about it? Ask for the certificate number and check the certifier’s register.
- What is the expiration date, and what is today’s date? Roughly a third of the certificates we were handed failed this.
- What product categories does the scope list, and is mine one of them? A capsule certificate does not cover a gummy.
If a brand can answer all three without hedging, they are ahead of most of the shelf. If they answer by sending you a screenshot of a table, you now know exactly what a table is worth.
