About Us
About Longevity Formulas
Longevity Formulas is a British supplement brand founded on a simple premise: that the longevity supplement market needed a brand that prioritised evidence over hype, transparency over marketing, and quality you could actually verify.
We are headquartered in Bedford, UK. Every product we sell is manufactured in a GMP-certified British facility, our NMN is independently third-party tested for purity and safety, and backed by a published Certificate of Analysis. That is not a marketing claim. The certificates are on the website for anyone to read.
Why we exist
When NMN began attracting serious scientific attention, largely through the work of researchers including Professor David Sinclair at Harvard Medical School, the supplement market responded the way it always does: quickly, loudly, and with very little accountability.
Brands proliferated. Claims escalated. Prices varied wildly with no clear explanation of why. And the people actually buying these supplements, adults in their 40s and 50s looking for a credible, affordable way to support their health, had almost no way of knowing whether what they were taking was genuine, pure, or worth the money.
Longevity Formulas was built to fix that specific problem.
The founder, Mat Stuckey, had been taking NMN himself for several years. He was not looking to build a supplement empire. He was looking for a British brand he could trust, at a price that made long-term use realistic, made to standards he could verify. When he could not find one, he built it.
What we actually believe about longevity supplements
We are not evangelical about supplements. We do not think NMN is a miracle. We do not think any single compound will reverse ageing or replace the fundamentals of sleep, exercise, and diet.
What we do believe, based on the available human clinical data, is that certain compounds interact with biological pathways that are genuinely relevant to how we age. NAD+ decline is real and measurable. Mitochondrial function declines with age. Oxidative stress accumulates. These are not contested claims. They are established biology.
NMN, CoQ10, NAC, resveratrol, and the other compounds in our range have varying levels of clinical evidence behind them. We are transparent about where that evidence is strong, where it is early-stage, and where questions remain unanswered. Our blog and product pages reflect that distinction clearly, because we think people deserve honest information rather than confident overclaiming.
The longevity science field is moving fast. We follow it closely, update our content when the evidence changes, and do not pretend certainty we do not have.
Our standards
Manufacturing Every product is manufactured in a GMP-certified facility in the United Kingdom. GMP (Good Manufacturing Practice) is the regulatory standard that governs pharmaceutical and supplement production in the UK, covering everything from raw material sourcing and production environment to quality control and batch documentation.
Third-party testing Every batch is independently tested by a third-party laboratory before it is released for sale. We test for purity, identity, and safety, including heavy metals, microbiological contaminants, and other potential adulterants. This testing is conducted by laboratories with no commercial relationship to us beyond the testing contract itself.
Certificates of Analysis We publish the Certificates of Analysis for every batch. This is the document that confirms what is in the product, at what purity, verified by an independent laboratory. Most supplement brands do not publish these. We do, because we think it is the minimum standard of transparency that a customer has a right to expect.
Formulation We do not use unnecessary fillers, binders, or flow agents. Where a product contains only one active ingredient, the capsule contains that ingredient and nothing else. Our delayed-release HPMC capsules are plant-based, vegan-friendly, and chosen for a specific functional reason: to protect acid-sensitive compounds through the stomach and deliver them to the small intestine where absorption occurs.
Who we make supplements for
Longevity Formulas products are designed for adults who approach their health with the same seriousness they bring to other areas of their life. People who read labels. People who want to understand the mechanism, not just the marketing. People who are sceptical of miracle claims but open to compounds with genuine scientific backing.
Our typical customer is in their 40s or 50s, active, health-conscious, and increasingly aware that the energy and recovery they took for granted in their 30s requires more deliberate support. They are not looking for a quick fix. They are building a long-term protocol.
They are also, frankly, tired of supplement brands that treat them like they cannot handle nuance. We try to be the brand that does not do that.
Our product range
Our range is built around the core mechanisms of biological ageing: NAD+ decline, mitochondrial dysfunction, oxidative stress, cellular senescence, inflammation, and epigenetic change. Each product is selected because it addresses one or more of these mechanisms with meaningful clinical evidence, not because it is trending.
Current range includes NMN (Pure 500mg and Complex formula), CoQ10, NAC, Magnesium Complex, Krill Oil, Collagen Powder, Creatine, and a range of curated bundles. New products are added when the evidence supports them and the manufacturing standards can be met, not before.
Transparency as a standard, not a selling point
The supplement industry has a transparency problem. Proprietary blends hide dosages. Certificates of Analysis are rarely published. Manufacturing claims are difficult to verify. Purity standards vary enormously between suppliers, and the price of a product bears little reliable relationship to its quality.
We are not the only brand trying to address this. But we are committed to it as a non-negotiable operating standard rather than a marketing angle. The certificates are published not because it differentiates us, but because it is the right thing to do.
