Best NMN Supplements 2025: Comprehensive UK Market Review
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.
As NAD+ declines with age, people turn to NMN to combat fatigue, enhance vitality, and support longevity. However, with a crowded market, choosing the right NMN supplement requires scrutiny beyond marketing claims.
This guide covers all major NMN options available in the UK for 2025 and examines their offerings.
What is NMN and Why Does it Matter?
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.
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
- 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. 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 like Healthspan. 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.
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.
