Our NMN Is Now Fully Third-Party Tested — See the Results
We have always been straightforward about what we are building at Longevity Formulas: pharmaceutical-grade NMN supplements, manufactured to GMP standards, at a price that does not ask you to compromise on quality. No inflated margins, no opaque sourcing, no vague assurances.
Today we are taking that commitment a step further. Every batch of our Pure NMN 500mg and NMN Complex is now fully independently tested by an accredited third-party laboratory (Eurofins) — and every test certificate is published publicly for you to read in full.
No request needed. No hoops to jump through. Just the results you deserve, permanently accessible.

Why We Are Doing This
The supplement industry has a trust problem. Most brands ask customers to accept a label at face value — and most customers have no realistic way to verify whether what is on that label reflects what is actually in the product.
We have never been comfortable with that arrangement. We chose GMP-certified UK manufacturing precisely because it imposes a documented quality standard at the point of production. We publish our Certificates of Analysis because they provide a verifiable record that goes beyond what any brand can simply claim about itself.
Third-party testing is the next logical step. It separates the verification of quality from the people who have a financial interest in it passing. An independent, accredited laboratory has one obligation: accuracy. Its reputation and accreditation depend on it. That independence is exactly what makes the results meaningful.
We are confident in these products. We are confident because we have tested them — and now you can see the results for yourself.
What Every Batch Is Tested For
Independent testing covers three areas, each addressing a distinct quality concern.
Heavy Metals Screening
Both products are screened for lead, arsenic, cadmium, and mercury against internationally recognised safety thresholds. Heavy metal contamination is one of the most commonly cited failures in supplement manufacturing — and it is not detectable without laboratory analysis.
Yeast and Mould Testing
Microbial contamination, including yeast and mould counts, is tested against acceptable limits for finished food supplements. This reflects manufacturing and storage risks that cannot be assessed from a label alone.
Purity and Identity Verification
Each batch is separately verified for compound identity and purity — confirmed at ≥98% pharmaceutical grade by mass. For NMN specifically, identity verification matters as much as purity percentage.
NMN sits within a family of structurally similar NAD+ precursors. NR (Nicotinamide Riboside) is cheaper to produce and requires an additional enzymatic conversion step before becoming NAD+. Without identity testing, there is no way to confirm a product contains genuine β-Nicotinamide Mononucleotide rather than a lower-cost substitute. Our certificates confirm compound identity explicitly — not just how much of something is present, but what that something actually is.
The NMN Complex: Six Ingredients, Six Things Verified
The NMN Complex contains NMN, TMG, Trans-Resveratrol, Pterostilbene, Quercetin, and Vitamin B12. Every compound is verified individually as part of the finished-product testing — the certificate does not simply cover the NMN and assume the rest.
Trans-Resveratrol is worth highlighting specifically. Resveratrol exists in two structural forms — trans and cis — and it is the trans isomer that features in the research on sirtuin pathway interaction. Cis-resveratrol is significantly cheaper and far less biologically active. Our NMN Complex Certificate of Analysis confirms trans-resveratrol specifically. Generic resveratrol labelling does not make that distinction.
GMP Manufacturing, Pharmaceutical-Grade Purity, Delayed-Release Delivery
Third-party testing does not exist in isolation. It sits alongside everything else we have built these products around.
Both supplements are manufactured in a GMP-certified UK facility — the same standard applied to licensed pharmaceutical products. Our NMN supplements use an acid-resistant delayed-release HPMC capsule, engineered to pass through the stomach intact and dissolve in the intestine where absorption occurs. Standard capsules dissolve in the stomach's low pH environment, where NMN can degrade before it reaches the site of uptake. The delivery system is chosen because the research points to it — not because it is the cheaper or easier option.
Pharmaceutical-grade purity. GMP manufacturing. Independent batch testing. Delayed-release delivery. Published certificates.
That is what we mean when we say we want the best for our customers — and it is what we mean when we say our products represent genuine value. Not the lowest price for something untested, but the best product we can build at a price that is honest.
Transparency Has Always Been the Foundation
We have always published our Certificates of Analysis. We have always been upfront about what is in our formulas, what the research shows, and where the evidence is still developing. We do not overclaim. We do not hide behind vague quality assurances.
Third-party testing is not a pivot — it is the next step in a direction we have always been heading.
We are proud of what is in these certificates. We want you to read them.
