The UK NMN market has exploded. There are now dozens of brands selling 500mg high-quality NMN raw material, independently tested for purity — and the price range is extraordinary. You can pay anywhere from £7.99 to £69.99 a month for what is, at its core, the same active ingredient at the same clinical dose.

This page exists because we think you deserve to know exactly what you're paying for — and what you're not. We're Little Ox, founded by Dr Chun Tang, a practising NHS GP with 26 years of clinical experience. We believe that high-quality NMN raw material, independently tested for purity should be accessible to everyone — not just those who can afford a premium brand.

The Price Comparison: 500mg NMN Per Day, Per Month

Prices correct as of June 2026 and checked against each brand’s published UK pricing. Competitor formats differ (powder vs capsule, multi-capsule servings), so cost-per-month is shown on a like-for-500mg-daily-dose basis where possible. Always check the current price on the brand’s own site. Competitor prices may vary. Little Ox prices include free delivery on UK orders over £35.00.

What the Price Difference Actually Means

The honest answer to why NMN prices vary so dramatically is not quality. The active ingredient — β-nicotinamide mononucleotide at independently tested high purity high-quality, independently tested purity — costs roughly the same to manufacture at scale. What you're paying for when you buy a £69.99 bottle is primarily brand-building, marketing spend, and retail margin.

Little Ox was founded to remove those costs. Dr Tang designed the formulas based on clinical evidence. We sell direct to you with no retail markup, no middlemen, and no celebrity licensing fees embedded in the price. The result is the same high-quality, independently tested ingredient, independently third-party tested, at a fraction of the cost.

The Annual Cost: What You're Really Spending

NMN is a supplement you take every day, indefinitely. The annual cost is what matters — and the difference between Little Ox and the premium brands is enough to buy a short holiday, several months of gym membership, or simply stay in your pocket.

What Competitors Do Better — and What They Don't

We believe in honesty, so here's a fair assessment:

Longevity Formulas offers delayed-release capsules, which is a genuine point of difference — the technology is designed to protect NMN from stomach acid. At ~£20/month it's also better value than most. It's a solid product. The question is whether delayed-release technology justifies 2.5x the price over Little Ox, when the fundamental active ingredient is the same. The clinical evidence doesn't currently establish that delayed-release NMN produces meaningfully better NAD+ outcomes than standard capsules at equivalent doses.

DoNotAge has a strong reputation in the longevity community and uses Uthever® branded NMN — a well-regarded source. They refrigerate products and test for post-shipping stability, which is careful. At its powder format, you're buying a low cost-per-serving product in a different format to our capsules — convenient single-capsule dosing and free delivery on UK orders over £35.00 on orders over £35 are where we differ.

Charava won the 2025 Beauty Shortlist Award for cognitive health and has a large content library. Their NMN is independently tested for purity. At £69.99/month they are the most expensive mainstream option — and more than 8x the price of Little Ox NMN Pure for effectively equivalent NMN content.

Uthful at £69/month positions itself as an all-in-one longevity formula with 20+ ingredients beyond NMN. If you want a single supplement covering multiple pathways, it's a different product category. If you specifically want high-quality NMN raw material, independently tested for purity at a clinical dose, it's expensive and the NMN content is diluted by the other ingredients.

The One Thing No Competitor Has

Every brand on this list can claim high-quality NMN raw material, independently tested for purity. Most can claim third-party testing. What none of them have is a practising NHS GP with 26 years of clinical experience as their founder — someone who sees patients every week, understands the real-world biology of ageing, and designed these formulas based on what the peer-reviewed evidence actually says rather than what sells.

Dr Tang takes NMN Plus himself every morning. He recommended it to patients before he founded Little Ox. That's not a marketing claim — it's the reason the brand exists.

Frequently Asked Questions

Is cheap NMN lower quality?
Not necessarily. The price of NMN supplements reflects marketing costs and brand positioning far more than ingredient quality. What actually determines quality is purity (independently tested high purity high-specification β-NMN, independently verified), independent third-party testing, and manufacturing standards — all of which Little Ox meets. Price alone tells you nothing about what's in the capsule.

Why is Little Ox so much cheaper than Charava or DoNotAge?
We sell direct to consumer with no retail markup, no intermediaries, and minimal marketing overhead. Dr Tang designed the formulas himself — there are no licensing fees for branded ingredients. We pass the savings directly to you.

Is Little Ox NMN the same dose as competitors?
Yes. Every Little Ox NMN product contains 500mg of β-NMN per capsule — the clinical dose used in peer-reviewed human trials. Some competitors use 250mg per capsule (requiring two per day to reach the same dose), which doubles the effective monthly cost.

Do I need to spend more for better results?
The clinical evidence doesn't support paying a premium for standard NMN. Results depend on consistent daily use of a high-quality, independently tested product at the correct dose — not on which brand it comes from. The most important factor is consistency over months, not price.

Can I see Little Ox's Certificate of Analysis?
Yes — our Certificate of Analysis is available on request. Email info@little-ox.co.uk and we'll send it to you directly.
