Every NMN Supplement on the UK Market in 2025
Here’s a look at all notable NMN brands available in the UK, including their strengths, weaknesses, and unique features.
1. Healthspan Formulas NMN
Potency
500mg per capsule
Features
Delayed-release capsules
60 capsules (2-month supply)
GMP-certified
No fillers
Price
£39.99
Analysis
Strikes an ideal balance of potency and affordability. Delayed-release technology protects NMN from stomach acid, enhancing absorption, a claim backed by science, unlike standard capsules, it is also certified pharmaceutical grade.
At under £20 per month, it’s a standout for value and quality.
2. Longevity Box NMNH
Potency
Varies (typically 250mg-500mg NMNH)
Features
Uses NMNH (a reduced form of NMN), 99% purity, enzymatic synthesis, 700-day purity guarantee
Price
£50-£70 (varies by size)
Analysis
Marketed as more potent than NMN, but evidence is limited, and the higher price feels unjustified without delayed-release or broader testing. Purity is a plus, but absorption remains unoptimised.
3. Purovitalis
Potency
150mg-300mgmg per serving
Features
Third-party tested, ships from the Netherlands
Price
£50
Analysis
A solid budget option with transparency via testing, but low dose, short supply and standard capsules may degrade in the stomach, potentially reducing effectiveness.
4. Renue by Science PURE NMN Powder
Potency
Customisable (powder form)
Features
High-purity powder, flexible dosing, mixes into drinks
Price
£51
Analysis
Powder offers versatility, but requires careful measuring and lacks advanced delivery systems. Claims of affordability don’t fully offset the inconvenience or potential absorption issues.
5. Quicksilver Scientific NAD+ Gold
Potency
50mg NMN per serving (with other NAD+ precursors)
Features
Liposomal liquid delivery, fast-acting
Price
£60-70 + shipping
Analysis
Liposomal tech boosts absorption, a rare evidence-based advantage, but the low NMN dose and high cost raise questions about value. It’s more of a premium niche product than a pure NMN solution.
6. Wonderfeel Youngr NMN
Potency
900mg per serving
Features
NMN with resveratrol, olive extract, and ergothioneine
Price
£75+
Analysis
A multi-ingredient approach that may appeal to longevity enthusiasts, but 900mg exceeds most research-backed doses, risking waste. Expensive and over-engineered for basic NMN needs.
7. ProHealth Longevity
Potency
1000mg per serving
Features
High-dose capsules, GMP-certified
Price
£80-100
Analysis
High potency appeals to advanced users, but doses above 500mg lack clear benefits in studies and may strain digestion without delayed-release. Reliable, yet not revolutionary and quite expensive.
8. GenuinePurity Liposomal NMN
Potency
250mg per serving
Features
Liposomal delivery, enhanced absorption
Price
£60-£70
Analysis
Liposomal tech is a legitimate plus, but the modest dose and premium price don’t compete with higher-potency options. Effective, yet overpriced for what’s delivered.
9. PartiQlar Pure NMN
Potency
500mg per capsule
Features
High-purity, no fillers, science-backed
Price
£64.99
Analysis
Clean and potent, but the steep price and lack of absorption-enhancing features (e.g., delayed-release) make it less compelling. Purity is great, value less so.
10. Omre NMN
Potency
250mg-500mg per serving
Features
NMN with pterostilbene, supports energy
Price
£50-60
Analysis
A balanced multi-compound formula, but NMN potency is diluted by extras. Decent for general wellness, less focused for pure NMN benefits.
11. Vitality Pro NMN
Potency
500mg per capsule
Supply
60 capsules (2 months)
Price
~£60
Key Features
Uses Uthever® NMN (clinically tested), delayed-release capsules, 99%+ purity
Analysis
Premium positioning with clinical backing, but considerably more expensive than Healthspan Formulas. Decent purity standards but the price point limits accessibility for most users.
12. NMN Bio
Potency
500mg per capsule
Supply
30 capsules (1 month)
Price
~£65
Key Features
UK-made, founded by Dr Elena Seranova (PhD in neurodegeneration), TMG combination available
Analysis
UK manufacturing, global shipping, but premium pricing. Suitable for those overseas. Price point for 1-month supply is very high vs competitors
13. AgeMate Pure NMN
Potency
250mg per capsule (2 capsules = 500mg daily)
Supply
60 capsules (1 month at full dose)
Price
~£35
Key Features
Acid-resistant capsules, GMP-certified UK manufacturing, third-party tested
Analysis
Competitive pricing but requires taking 2 capsules daily, making it less convenient and shorter supply. Reasonable budget option but shorter supply duration affects the value proposition.
14. DoNotAge Pure NMN
Potency
500mg per capsule
Supply
60 capsules (2 months)
Price
~£55
Key Features
99.8% purity verification, refrigerated storage until dispatch, global reputation
Analysis
Excellent purity standards and storage protocols, but higher price point. Strong brand recognition in the longevity community but less accessible for everyday users.
15. Strong Life NMN
Potency
Various options available
Supply
Multiple bottle sizes
Price
~£25-45 depending on option
Key Features
Budget-friendly options, UK-based
Analysis
More affordable entry point but at lower doses, limited information on purity verification and manufacturing standards. Suitable for price-conscious consumers willing to compromise on premium features.
What is NMN and Why Does it Matter?
Nicotinamide Mononucleotide (NMN) supplements are increasingly popular in the UK for their role in boosting NAD+ levels, a vital coenzyme that supports energy production, metabolism, and healthy ageing.
NMN is a precursor to NAD+, a molecule essential for cellular energy, DNA repair, and metabolic health. Ageing reduces NAD+ levels, contributing to tiredness, slower metabolism, and cognitive decline.
NMN supplements aim to replenish NAD+, but effectiveness depends on potency, absorption, and quality, factors often overstated by brands. Below, we review each option on the market, challenging the establishment narrative where necessary.
The Problem with Cheap NMN Alternatives
Cheap NMN supplements flood online marketplaces, often priced under £20. However, 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.
The establishment narrative pushes NMN as a cure-all, but cheap options exploit this hype without delivering results. Reputable brands like those in this list justify their cost with quality and science.

Critical Takeaways
- Healthspan Formulas leads with a practical 500mg dose, delayed-release for proven absorption, and unbeatable value at £39.99 for 60 days.
- Premium options like Quicksilver and GenuinePurity offer liposomal delivery but charge more for less NMN.
- High-dose products (Wonderfeel, ProHealth) may overshoot effective levels, banking on “more is better” hype.
- Cheap alternatives fail on quality and absorption, undermining the NMN promise.
The narrative that all NMN supplements are equal is flawed, delivery, purity, and dosage matter more than brand buzz.
Conclusion: Why Healthspan Formulas Wins
For 2025, Healthspan Formulas comes as the top NMN supplement in the UK. Its 500mg potency, delayed-release capsules, 2-month supply, and £39.99 price deliver unmatched quality and value.
While competitors offer other features or higher doses, they often lack the practical edge or affordability of Healthspan Formulas. Skip the cheap knockoffs and overhyped alternatives, choose a supplement that works as promised.
