Founded on a Principle

The UK supplement market has a problem. The products at the top of the price range — £40, £60, £70 a month — are often not meaningfully better than the honest, well-made alternatives. The premium is marketing, not quality. Patients who need these supplements most are the ones most likely to be priced out of taking them consistently.

Dr Chun Tang has been a practising NHS GP for over 26 years. He has seen first-hand what cellular decline looks like in his patients — the fatigue in their 40s they assume is just age, the cognitive sluggishness they normalise, the metabolic changes they accept as inevitable. He knows what the science says. He also knows what the NHS can and cannot offer in terms of preventative cellular health support.

Little Ox was built to close that gap. The same high-quality NMN raw material, independently tested for purity that the leading longevity researchers take themselves. The same independent certifications. The same third-party testing. At a price that makes long-term use possible for everyone — not just those who can afford £70 a month.

Quality You Can Actually Verify

Any supplement brand can say "high-quality, independently tested." We can prove it. Our manufacturing facility holds nine active independent certifications. Our NMN is tested by a third-party laboratory on every batch — not once at launch, not self-declared, but independently verified before every release.

Our independent Certificate of Analysis confirms Independently tested purity: 95.8%, zero heavy metals detected across all five metals tested (ICP-MS), and zero microbial contamination across six pathogens. Every batch. Before release. View all certifications and CoA results →

The Price Promise

The reason we can do this is structural, not magical. We sell direct to consumer. We don't pay for shelf space. We haven't spent millions on celebrity ambassadors. We've passed every saving directly to you, and we've been transparent about exactly what you're getting for the price.

We believe that supplements people can actually afford to take consistently work better than expensive ones they take sporadically. The clinical evidence for NMN is built on consistent daily use. £7.99 a month makes that consistency possible for everyone.

Our Brand Ambassador

Kerry Katona has been a brilliant ambassador for Little Ox since the early days of the brand. Broadcaster, businesswoman, mother of five — she's a working entrepreneur in her own right who understands first-hand the cellular cost of building things and being there for the people who depend on you.

We are proud of the relationships we build with people who genuinely connect with the brand's mission.

What We Stand For

• Clinical honesty. We tell you what the evidence shows — and what it doesn't. Dr Tang's name is on this brand. His GMC registration and professional reputation depend on the accuracy of every claim we make.
• Transparent pricing. You can see exactly what you're paying for. Our products are priced at what they should cost, not what the market will bear.
• high specification quality, independently verified. Not because we have to — because our customers deserve to know that what's on the label is what's in the capsule.
• UK-based, UK-run. Founded, operated and fulfilled from Britain. When you contact us, you speak to someone on our team.
• No noise. No proprietary blends to obsaddress low doses. No inflated label claims. No supplements that exist to fill a range rather than serve a need. Every product we sell exists because there is evidence for it.
• Accessible to everyone. A 26-year NHS GP built this brand. The NHS principle — that quality healthcare should be accessible regardless of means — runs through everything we do.
