📋 Food Supplement: NMN is a food supplement — not a medicine. Not intended to diagnose, treat, cure or prevent any disease. No authorised EU/UK health claims exist for NMN as a food supplement. All information on this page is provided for educational purposes only. Published April 2025.
🧬 What Is NMN — The Short Version
NMN (Nicotinamide Mononucleotide, CAS 1094-61-7) is a nucleotide compound related to the vitamin B3 family. It is naturally present in trace amounts in some foods including broccoli, cabbage, edamame and avocado. In the UK it is sold as a food supplement ingredient — not a medicine, not a pharmaceutical, and not a licensed treatment for any condition.
NMN has attracted significant scientific interest since the mid-2010s. It is one of the most researched food supplement ingredients in the world. That research interest does not translate into authorised health claims under EU/UK Regulation 1924/2006 — no such claims currently exist for NMN — but it does explain why it has become one of the most purchased supplement ingredients in the UK market.
We started supplying NMN in 2016. At that point, the UK market had a handful of suppliers. Today there are hundreds. Most of what we have learned over 9+ years is not about NMN science — it is about how to tell a quality product from a poor one. That is what this guide is about.

-
Is the NMN independently 3rd party tested — and which lab?
Not just "tested" — named lab. Eurofins, Certified Labs, Micro Quality Labs. A generic "tested" claim means nothing without a name. -
What purity percentage is confirmed?
Look for ≥99% declared purity from an independent test. 99.94% is our Eurofins-confirmed capsule figure. 99.9% is our powder figure. -
Is the capsule Size 0?
Size 0 holds ~530mg — correct for 500mg pure NMN with no room for filler. Size 00 holds ~700mg — the extra 170-200mg is filler you didn't ask for. -
Are there fillers on the ingredient panel?
MCC (Microcrystalline Cellulose), magnesium stearate, silicon dioxide, brown rice flour — all fillers. If they're on the label, you're paying NMN prices for filler. -
Is the COA available on request?
Certificate of Analysis — issued by the independent lab, not the seller. Should be available for the specific batch you are buying. -
Does the seller have verifiable UK sales history?
eBay feedback, verified marketplace sales, Food Hygiene Rating — all independently verifiable. Marketing copy is not independently verifiable. -
Is the NMN encapsulated in-house or bought as finished capsules?
In-house encapsulation = seller controls the raw ingredient and fill process. Buying finished capsules = chain of custody risk.

👅 The At-Home Purity Test — Do This With Every NMN Batch
No matter where you buy NMN from — do this test with every new batch. It takes 10 seconds and cannot be faked.
✅ Pure NMN — what to expect
- Dissolves cleanly in 3–5 seconds
- Sharp, zesty citrus aftertaste
- No bitterness
- No chalky or gritty residue
❌ Fake or filled — warning signs
- Slow to dissolve or doesn't dissolve
- Intensely bitter taste
- Chalky or pasty residue
- Clumps under the tongue
Pure NMN has a distinctive zesty taste profile. B3 Nicotinamide — the most common substitute used in fake NMN — is intensely bitter by comparison. Once you have tasted real NMN, the difference is unmistakable. A COA can be forged or reused from a previous batch. The taste test cannot.
✅ Want to do the taste test right now?
Our NMN 500mg Capsules are Size 0, Eurofins tested at 99.94% pure, with zero fillers. Order today — open one capsule, do the taste test, and judge for yourself.
