Charge Products NMN — Eurofins Tested at 99.99% Purity.
Ranked #1 on Google. Here's What That Actually Means.
Charge Products NMN 500mg is independently tested by Eurofins — the world's largest network of independent testing laboratories — and verified at 99.99% purity. Eurofins UK operates under UKAS accreditation to ISO/IEC 17025:2017 — the international standard for testing laboratory competence used by pharmaceutical manufacturers, food safety authorities and government bodies. We ranked number 1 on Google for "buy NMN capsules Eurofins tested" in May 2026 — reflecting the consistency and transparency with which we state our testing standard, name our laboratory and publish our purity result. Food supplement — not a medicine. NMN has no authorised UK health claims.
Why Charge Products NMN Is the Gold Standard for UK Buyers in 2026
In May 2026 Charge Products achieved the number 1 organic Google ranking for the search term "buy NMN capsules Eurofins tested" — one of the highest-intent NMN buyer queries in the UK market. This ranking was not paid for and was not the result of advertising spend. It reflects the consistency of the message across our product listings, blog content and customer feedback: we test with Eurofins, we state 99.99% purity, and we can prove it. This post is an explanation of why that matters — and why most NMN brands in the UK cannot say the same thing.
If you have been searching for NMN capsules UK you will have noticed that almost every brand now claims to be "third-party tested." It is one of the most frequently used phrases in the supplement industry — and one of the least regulated. Third-party tested can mean anything from a full ISO 17025-accredited independent laboratory analysis, to a single in-house test signed off by a partner facility with no external accreditation at all.
The question that matters is not whether a brand is "third-party tested." The question is: who tested it, to what standard, and what exactly did the test find? This post answers all three of those questions for Charge Products NMN — and explains why Eurofins testing represents a materially higher standard than most of what is available in the UK NMN market.
What Is Eurofins — and Why Does It Matter?
Eurofins Scientific is the world's largest network of independent testing and laboratory services companies. Founded in 1987 and publicly listed on Euronext Paris, Eurofins operates more than 900 laboratories across 50+ countries and employs over 60,000 people. Its clients include pharmaceutical manufacturers, food safety authorities, government departments, NHS trusts, and multinational food and beverage companies.
In the UK, Eurofins operates multiple laboratories accredited by UKAS — the United Kingdom Accreditation Service — the sole national body recognised by the UK government for the accreditation of testing, calibration and certification bodies. Eurofins Food Testing UK Limited holds UKAS accreditation number 9659 under ISO/IEC 17025:2017 — the international standard for testing laboratory competence — assessed and renewed annually.
What ISO/IEC 17025:2017 Actually Means
ISO/IEC 17025:2017 is the international standard that sets the requirements for testing and calibration laboratory competence. It covers:
- Technical competence — the laboratory must demonstrate it has the equipment, methods and trained staff to perform the tests it offers
- Method validation — the analytical methods used must be scientifically validated and documented
- Measurement uncertainty — results must include a statement of measurement uncertainty, meaning the lab must quantify how accurate its results are
- Impartiality — the laboratory must be demonstrably independent from the organisation whose product it is testing
- Annual audit — UKAS conducts annual on-site assessments to verify continued compliance
This is the standard that pharmaceutical manufacturers use when they need legally defensible purity data. It is the standard NHS procurement requires for clinical laboratory testing. It is the standard that food safety enforcement authorities use when testing products for regulatory purposes. It is not the standard used by most supplement "third-party testers."
"Third-party tested" is not a regulated term in the UK supplement industry. Any supplement brand can claim to be third-party tested. Some use UKAS-accredited ISO 17025 laboratories. Some use GMP-compliant partner facilities with no external accreditation. Some use overseas labs with no recognised UK or EU accreditation framework. The phrase alone tells you nothing. The name of the laboratory and its accreditation status tells you everything.
How Charge Products NMN Compares on Testing Standard
| Testing Factor | Charge Products | Charava | Do Not Age | Generic Amazon |
|---|---|---|---|---|
| Testing Laboratory | Eurofins UK ✓ | US-based lab | Uthever partner lab | Often unnamed |
| Accreditation Standard | UKAS ISO 17025 ✓ | US GMP standard | ISO 9001 / GMP | Not stated |
| Lab Location | United Kingdom ✓ | United States | Not UK | Varies / unknown |
| Annual External Audit | Yes — UKAS ✓ | US equivalent | GMP audit | Not confirmed |
| Declared Purity | 99.99% ✓ Highest | 99.8% | 99.8% | Often not stated |
| CoA Availability | Yes — on request ✓ | Yes — on website | Yes — on website | Rarely available |
| Testing Method | HPLC ✓ | HPLC | HPLC | Not stated |
Why 99.99% Purity — Not 99.8% — Is the Number That Matters
Every NMN brand in the premium UK market claims high purity. The difference between 99.8% and 99.99% might look small on paper. Over daily supplementation it is not small at all.
At 500mg NMN daily · 365 days = 182,500mg consumed per year.
At 99.8% purity: 182,135mg active NMN + 365mg impurities per year.
At 99.99% purity: 182,482mg active NMN + 18.25mg impurities per year.
That is 347mg more active NMN and 347mg fewer impurities per year at 99.99% vs 99.8%. Every year. Every day you take it.
The primary impurities in NMN synthesis are nicotinamide (niacinamide) and related B3 vitamin compounds — generally considered safe. But the principle is straightforward: if you are paying for NMN, you want NMN, not impurities. The higher the purity verified by an independent accredited laboratory, the more of what you paid for is actually in the capsule.
Why Google Ranked Us Number 1
In May 2026 Charge Products achieved the number 1 organic ranking on Google for "buy NMN capsules Eurofins tested." This is a high-intent commercial query — buyers using this search term are not researching. They are ready to purchase, and they specifically want Eurofins-verified NMN.
The ranking reflects several things happening simultaneously across the Charge Products digital presence:
- Consistency — "Eurofins tested" and "99.99% purity" appear on the eBay listing, the Shopify product page, the blog and in the meta descriptions. Google rewards consistent, specific, factual claims across multiple pages of the same domain
- Specificity — most competitors say "third-party tested." We say "Eurofins tested." Specific trumps vague in search — always
- Trust signals — 156,000+ verified sales, 5 Star Food Hygiene, UK trading since 2016, 99.7% positive feedback. Google's E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) rewards verifiable credentials
- No paid ads — this is a purely organic ranking. It cannot be bought. It has to be earned by the quality and consistency of the content and the credibility of the brand behind it

No middlemen, no mystery blends, no chain of custody gaps. The tests below are ones you can do yourself — right now, at home — and they do not lie.
| Factor | ✔ Size 0 — Correct (Ours) | ✘ Size 00 — Fillers Hidden |
|---|---|---|
| Capsule volume | Holds approx 530mg ✅ | Holds approx 700mg ❌ |
| For 500mg pure NMN | Correct — no room for fillers ✅ | Extra ~200mg = fillers ❌ |
| Charge Products capsules | ✔ Size 0 only — confirmed | Up to 11g hidden fillers/month |
| Filled capsule weight | 530–560mg — no extras ✅ | Over 700mg — extra is fillers ❌ |
| What You Experience | ✔ Pure NMN | ✘ Fake / Filled NMN |
|---|---|---|
| Taste | Sharp, zesty citrus — clean ✅ | Intensely bitter — harsh ❌ |
| Dissolve time | 3–5 seconds clean ✅ | 30–45 seconds or longer ❌ |
| Texture | Fine dry powder — no residue ✅ | Clumps, sticks, gritty ❌ |
| Residue | Clean dissolve ✅ | Chalky, pasty residue ❌ |
| Factor | ✔ Real NMN | ✘ B3 Nicotinamide Substitute |
|---|---|---|
| Taste | Sharp zesty citrus — clean ✅ | Intensely bitter — harsh ❌ |
| Dissolve time | 3–5 seconds clean ✅ | 30–45 seconds or longer ❌ |
| Texture under tongue | Fine, dry — no residue ✅ | Clumps, sticks, gritty ❌ |
| Raw cost | Higher — genuine compound ✅ | Fraction of cost — common swap ❌ |
| Certificate reliability | Eurofins confirms — taste agrees ✅ | Certificates can be falsified ❌ |
❌ Fillers like MCC, maltodextrin and rice flour all dissolve in water — indistinguishable from NMN
❌ B3 Nicotinamide — the most common NMN substitute — also dissolves rapidly and looks identical
❌ If a seller promotes the water test, ask why they won't let you do the taste test instead
✔ The taste test is the only at-home test that cannot be faked. Sharp citrus = real NMN. Intensely bitter, clumping or slow dissolve = not pure NMN.
Taste test ✅ — Sharp zesty citrus · dissolves in 3–5 seconds · no residue
NMN vs B3 test ✅ — Citrus not bitter · clean fast dissolve · Eurofins confirms and taste agrees
Water test — not a valid test for any NMN supplement
Certificate of Analysis ✅ — Eurofins · UKAS 9659 · ISO/IEC 17025:2017 · HPLC · 99.99% · available on request
If your NMN capsule doesn't pass the taste test — sharp citrus, clean 3–5 second dissolve — contact us and we will replace it.
