Every Major NMN Brand in the UK (2026)
1. Longevity Formulas Pure NMN
| Feature | Details |
|---|---|
| Dose | 500mg per capsule |
| Supply | 60 capsules (2 months) |
| Technology | Delayed-release (acid-resistant) |
| Purity | Pharmaceutical-grade, CoA published |
| Price | £39.99 (£0.67/day) |
| Manufacturing | UK, GMP certified |
Why it stands out: Combines clinically-relevant dosing with delayed-release technology at the lowest cost per month of any premium brand. The acid-resistant capsules protect NMN from stomach degradation, and published Certificates of Analysis and third party test results provide complete transparency. At under £20 per month for a 2-month supply, it offers the best value-to-quality ratio.
Best for: Anyone seeking pharmaceutical-grade NMN with proven absorption technology at an accessible price point.
2. Vitality Pro NMN
| Feature | Details |
|---|---|
| Dose | 500mg per capsule |
| Supply | 60 capsules (2 months) |
| Technology | Delayed-release, Uthever® NMN |
| Purity | 99%+ (clinically tested) |
| Price | ~£60 (£1.00/day) |
| Manufacturing | Uses clinically-backed Uthever® |
Why it stands out: Premium positioning with Uthever® NMN, which has been used in some clinical trials. Delayed-release capsules provide good absorption.
Trade-offs: Considerably more expensive than Longevity Formulas (50% higher cost) for similar technology and supply duration. The Uthever® branding adds cost without clear evidence of superiority over pharmaceutical-grade NMN.
Best for: Those who specifically want Uthever®-branded NMN and aren't price-sensitive.
3. NMN Bio
| Feature | Details |
|---|---|
| Dose | 500mg per capsule |
| Supply | 30 capsules (1 month) |
| Technology | Standard capsules |
| Purity | Pharmaceutical-grade, >99% |
| Price | ~£60 (£2.00/day) |
| Manufacturing | UK, founded by research scientist |
Why it stands out: Founded by Dr Elena Seranova, a researcher with PhD in neurodegeneration, bringing scientific credibility. UK manufacturing with comprehensive allergen-free certification.
Trade-offs: Standard capsules expose NMN to stomach acid. At £60 for only 30 capsules (1 month), it's 3x more expensive per day than Longevity Formulas. Half the supply duration at 50% higher bottle price significantly impacts value.
Best for: Those who value the founder's scientific credentials and don't mind premium pricing.
4. DoNotAge Pure NMN
| Feature | Details |
|---|---|
| Dose | 500mg per capsule |
| Supply | 60 capsules (2 months) |
| Technology | Standard capsules |
| Purity | 99.8% verified |
| Price | ~£55 (£0.92/day) |
| Manufacturing | Refrigerated storage until dispatch |
Why it stands out: Excellent purity standards (99.8%) and careful refrigerated storage protocols. Strong reputation in the longevity community globally.
Trade-offs: Standard capsules without delayed-release technology. Higher price than Longevity Formulas (£55 vs £39.99) for the same supply duration without absorption-enhancing features.
Best for: Brand loyalists who trust DoNotAge's reputation and storage protocols.
5. AgeMate Pure NMN
| Feature | Details |
|---|---|
| Dose | 250mg per capsule (500mg = 2 caps) |
| Supply | 60 capsules (1 month at full dose) |
| Technology | Acid-resistant capsules |
| Purity | GMP-certified, third-party tested |
| Price | ~£35 (£1.17/day) |
| Manufacturing | UK, GMP certified |
Why it stands out: Competitive pricing with acid-resistant capsules. UK manufacturing with third-party testing provides quality assurance.
Trade-offs: Requires taking 2 capsules daily to reach 500mg, which is less convenient. The 60-capsule bottle only lasts 1 month at full dose, making it actually more expensive per month than it initially appears. At £35/month, it costs 75% more than Longevity Formulas whilst providing half the supply duration.
Best for: Those comfortable taking 2 capsules daily and wanting a mid-range price point.
6. Quicksilver Scientific NAD+ Gold
| Feature | Details |
|---|---|
| Dose | 50mg NMN per serving (+ other precursors) |
| Supply | 30 servings (1 month) |
| Technology | Liposomal liquid delivery |
| Purity | High-quality ingredients |
| Price | £60-70 (£2.00-2.33/day) |
| Manufacturing | USA, premium formulation |
Why it stands out: Liposomal delivery technology genuinely enhances absorption - one of the few evidence-backed delivery methods. Fast-acting liquid format. Includes multiple NAD+ precursors beyond just NMN.
Trade-offs: Only 50mg NMN per serving (10% of standard dose). The multi-ingredient approach dilutes NMN content. Very expensive at £60-70 for a 1-month supply. More of a premium NAD+ cocktail than a pure NMN supplement.
Best for: Those wanting liposomal technology and don't need high-dose NMN specifically.
7. PartiQlar Pure NMN
| Feature | Details |
|---|---|
| Dose | 500mg per capsule |
| Supply | 60 capsules (2 months) |
| Technology | Standard capsules |
| Purity | High-purity, no fillers |
| Price | £64.99 (£1.08/day) |
| Manufacturing | Science-backed formulation |
Why it stands out: Clean formulation with no fillers. Solid purity standards and 2-month supply.
Trade-offs: Premium pricing (£64.99) without advanced absorption features like delayed-release or liposomal delivery. 62% more expensive than Longevity Formulas for standard capsule technology.
Best for: Those prioritising "no filler" formulation over absorption technology and cost.
8. GenuinePurity Liposomal NMN
| Feature | Details |
|---|---|
| Dose | 250mg per serving |
| Supply | Varies by product |
| Technology | Liposomal delivery |
| Purity | Quality formulation |
| Price | £60-£70 (~£2.00-2.33/day) |
| Manufacturing | Liposomal encapsulation |
Why it stands out: Liposomal technology is a legitimate absorption enhancer, protecting NMN and improving bioavailability.
Trade-offs: Modest 250mg dose (half of standard). Premium pricing (£60-70) doesn't compete well against higher-potency options with delayed-release technology. Paying a significant premium for liposomal delivery of a relatively low dose.
Best for: Liposomal technology enthusiasts willing to accept lower doses at premium prices.
9. Purovitalis NMN
| Feature | Details |
|---|---|
| Dose | 150-300mg per serving |
| Supply | 30 capsules (1 month) |
| Technology | Standard capsules |
| Purity | Third-party tested |
| Price | ~£50 (£1.67/day) |
| Manufacturing | Ships from Netherlands |
Why it stands out: Third-party testing provides transparency. EU-based with international shipping.
Trade-offs: Low dose (150-300mg) compared to research-backed 500mg. Standard capsules may degrade in stomach. Short supply (30 days) at £50 makes it expensive per month. Lower potency and standard delivery at premium pricing.
Best for: EU customers wanting locally-shipped NMN and comfortable with lower doses.
10. Wonderfeel Youngr NMN
| Feature | Details |
|---|---|
| Dose | 900mg per serving |
| Supply | 30 servings (1 month) |
| Technology | Standard capsules |
| Purity | High-quality multi-ingredient |
| Price | £75+ (£2.50+/day) |
| Manufacturing | Premium multi-ingredient formula |
Why it stands out: Very high dose (900mg) plus resveratrol, olive extract, and ergothioneine. Comprehensive longevity formula approach.
Trade-offs: 900mg exceeds doses used in most research (250-500mg), with no evidence higher is better. May be wasteful if body can't utilise excess. Very expensive at £75+ for 1 month. Over-engineered for those wanting pure NMN.
Best for: Longevity enthusiasts wanting a multi-ingredient approach and unconcerned about cost.
11. ProHealth Longevity NMN
| Feature | Details |
|---|---|
| Dose | 1000mg per serving |
| Supply | Varies by product |
| Technology | Standard high-dose capsules |
| Purity | GMP-certified |
| Price | £80-100 (~£2.67-3.33/day) |
| Manufacturing | GMP-certified facility |
Why it stands out: Extremely high dose (1000mg) for those believing more is better. Established brand with GMP certification.
Trade-offs: Doses above 500mg lack clear benefits in clinical studies. Without delayed-release, high doses may strain digestion and much could be degraded in stomach. Very expensive at £80-100. Reliability without innovation.
Best for: Advanced users specifically wanting mega-doses despite lack of supporting research.
12. Renue by Science PURE NMN Powder
| Feature | Details |
|---|---|
| Dose | Customisable (powder form) |
| Supply | Varies by container |
| Technology | Powder (mix into drinks) |
| Purity | High-purity powder |
| Price | ~£51 |
| Manufacturing | Flexible dosing option |
Why it stands out: Powder format offers complete dosing flexibility. Can mix into drinks or take sublingually.
Trade-offs: Requires careful measuring (easy to under or over-dose). No advanced delivery system to protect from stomach acid. Taste may be unpleasant. Less convenient than capsules. "Affordability" claims don't offset absorption concerns.
Best for: Those preferring powder format and comfortable with manual measuring.
13. Longevity Box NMNH
| Feature | Details |
|---|---|
| Dose | Varies (typically 250-500mg NMNH) |
| Supply | Varies by product |
| Technology | Uses NMNH (reduced form of NMN) |
| Purity | 99%, enzymatic synthesis |
| Price | £50-£70 |
| Manufacturing | 700-day purity guarantee |
Why it stands out: Uses NMNH, marketed as more potent than standard NMN. High purity with long stability guarantee.
Trade-offs: NMNH evidence is limited compared to standard NMN. Higher price (£50-70) without delayed-release or proven absorption advantage. Purity is good but absorption remains unoptimised. Premium pricing for unproven superiority.
Best for: Early adopters interested in alternative NMN forms despite limited research.
14. Omre NMN
| Feature | Details |
|---|---|
| Dose | 250-500mg per serving |
| Supply | Varies by product |
| Technology | Standard capsules |
| Purity | Quality formulation |
| Price | £50-60 |
| Manufacturing | Includes pterostilbene |
Why it stands out: Balanced multi-compound formula with pterostilbene for additional benefits. Decent for general wellness approach.
Trade-offs: NMN potency diluted by additional ingredients. Standard delivery without absorption enhancement. Less focused for pure NMN supplementation.
Best for: Those wanting a combined NMN/pterostilbene supplement for general wellness.
15. Strong Life NMN
| Feature | Details |
|---|---|
| Dose | Various options available |
| Supply | Multiple bottle sizes |
| Technology | Standard capsules |
| Purity | Limited information available |
| Price | £25-£45 depending on option |
| Manufacturing | UK-based, budget-friendly |
Why it stands out: Most affordable entry point for those testing NMN supplementation. UK-based.
Trade-offs: Lower doses in most options. Limited information on purity verification and manufacturing standards. No advanced delivery technology. Suitable for price-conscious consumers willing to compromise on premium features.
Best for: Budget-conscious beginners wanting to trial NMN at minimal cost.

The Problem With Cheap NMN Alternatives
Cheap NMN supplements (under £20) flood online marketplaces, but they're a gamble:
Quality control: Many lack GMP certification, risking contamination or inconsistent NMN levels.
Effectiveness: Without delayed-release or liposomal delivery, most NMN degrades in the stomach, delivering minimal NAD+ benefits.
Transparency: Unverified brands may use fillers or mislabel potency, wasting your money.
Reputable brands justify their cost with verifiable quality, appropriate dosing, and absorption technology.
Why You Can Trust This Comparison
Full transparency upfront: We're Longevity Formulas, and our NMN product is included in this comparison. However, we've evaluated every brand using the same objective criteria we'd use if we were purchasing NMN ourselves.
Evidence-based criteria: We assess brands on factors that actually affect NMN effectiveness - absorption technology, verified purity, appropriate dosing, and value for money - not marketing buzzwords or packaging design.
Honest trade-offs: Every product has strengths and weaknesses. We acknowledge when competitors excel in certain areas and clearly explain where each product falls short.
No affiliate relationships: We don't earn commissions from recommending other brands. When we link to competitors, it's to help you make informed decisions, not to generate revenue.
Regular updates: We revisit this comparison quarterly as new products launch and existing brands improve their offerings.
The Four Factors That Actually Matter
After reviewing the research on NMN supplementation and analysing every major UK brand, these are the criteria that determine whether an NMN supplement works as promised:
1. Absorption Technology
NMN must survive stomach acid to reach the small intestine where it's absorbed. Standard capsules dissolve in the stomach, exposing NMN to degradation. Evidence-backed solutions include:
- Delayed-release capsules: Acid-resistant coating protects NMN until it reaches the intestines
- Liposomal delivery: Encapsulates NMN in lipid bubbles that protect it through digestion
- Standard capsules: No protection - NMN exposed to stomach acid immediately
2. Dosage and Purity
Clinical research on NMN typically uses doses between 250-500mg daily. Higher doses haven't been shown to provide proportionally greater benefits, whilst lower doses may be insufficient.
Purity matters because contaminated or degraded NMN won't deliver expected results. Look for pharmaceutical-grade purity (>99%) with published Certificates of Analysis.
3. Supply Duration and Value
A bottle's price matters less than its monthly cost. Compare:
- £40 for 60 capsules (2-month supply) = £20/month
- £60 for 30 capsules (1-month supply) = £60/month
The second option costs 3x more despite seeming only £20 more expensive.
4. Manufacturing Standards
GMP (Good Manufacturing Practice) certification ensures consistent quality and safety. UK or EU manufacturing provides regulatory oversight. Published testing results offer transparency that marketing claims cannot.
Why Longevity Formulas Stands Out
After evaluating every major option, Longevity Formulas offers the most compelling combination of factors that matter:
Optimal absorption: Delayed-release capsules protect NMN from stomach acid degradation, ensuring it reaches the intestines intact.
Research-backed dosing: 500mg per capsule aligns with clinical studies showing NAD+ benefits.
Complete transparency: Published Certificates of Analysis for every batch show exactly what you're getting.
Best value: At £39.99 for 60 capsules (2-month supply), it costs just £0.67/day - less than half the cost of most competitors.
UK manufacturing: GMP-certified facility ensures consistent quality and safety.
Whilst competitors offer features like higher doses (unproven to be better), fancy branding, or multi-ingredient formulas, they typically cost 50-300% more without delivering proportionally greater benefits.
How to Choose the Right NMN For You
If budget is your priority: Strong Life (£25-45) offers the cheapest entry point, though with compromises on purity verification and absorption.
If you want liposomal technology specifically: Quicksilver NAD+ Gold or GenuinePurity, but expect to pay £60-70+ for relatively low NMN doses.
If you want the best value-for-money with proven absorption: Longevity Formulas at £39.99 for 2 months with delayed-release technology.
If you want mega-doses (despite lack of evidence): Wonderfeel (900mg) or ProHealth (1000mg), but at premium prices.
If brand reputation matters most: DoNotAge or NMN Bio have strong reputations, though at significantly higher costs.
Final Verdict
For 2026, Longevity Formulas represents the best NMN supplement in the UK for most people. It combines pharmaceutical-grade purity, delayed-release absorption technology, clinically-relevant 500mg dosing, and a 2-month supply at £39.99 - offering the best quality-to-cost ratio on the market.
Whilst premium options exist for those with specific preferences (liposomal delivery, mega-doses, particular brands), they typically cost 50-200% more without proportional benefits.
Skip the cheap knockoffs that lack absorption technology and the overpriced alternatives that add cost without clear advantage. Choose a supplement that delivers proven quality at an accessible price.
