Best Longevity Supplement Brands UK 2025: Complete Comparison Guide
Which longevity supplement brands actually deliver quality products at fair prices? We've analysed the leading companies in the UK market to give you an honest comparison.
Here's our evaluation of the top longevity supplement brands, ranked by quality, transparency, value, and customer satisfaction.
1. Longevity Formulas 🏆
Your Best Choice for Quality and Value
Why We're #1:
As the leading UK longevity supplement company, we've built our reputation on delivering pharmaceutical-grade quality at accessible prices. Here's what sets us apart:
Key Products:
- NMN 500mg - £39.99 for 60 capsules (2-month supply)
- NMN Complex - £44.99 (NMN + TMG + Resveratrol + Quercetin + Pterostilbene + B12)
Standout Features:
✅ Delayed-release capsules - protects NMN from stomach acid (unlike standard capsules)
✅ Pharmaceutical-grade manufacturing with certificates of analysis
✅ 2-month supply vs competitors' 1-month offerings
✅ No fillers or proprietary blends - complete transparency
✅ Unbeatable value - £20/month vs competitors at £35-60/month
Customer Feedback: "I was skeptical at first, but after a month of Pure NMN, I can honestly say I feel the difference. More energy, better focus – it's become a non-negotiable part of my day."
Critical Analysis: We've achieved the optimal balance of pharmaceutical-grade quality without pharmaceutical-grade pricing. Our delayed-release technology alone justifies choosing us over brands using standard capsules, while our 2-month supply model provides significantly better value than competitors' monthly offerings.
Best For: Anyone wanting premium quality longevity supplements without premium pricing. Perfect for both beginners and experienced users.
2. DoNotAge
Health Research Organisation Approach
DoNotAge positions itself as a health research organisation rather than a supplement company, claiming their products are used by leading longevity researchers.
Key Products:
- Pure NMN (500mg) - £55 for 60 capsules (2-month supply)
- Starter Pack (6 compounds) - £80-100
- Individual compounds (Berberine, TMG, Fisetin, etc.) - £25-50
Strengths:
- Claims to fund actual longevity research
- Very high purity standards (99.8% NMN purity verification)
- Wide range of cutting-edge longevity compounds
- Global presence with over 200,000 customers
- Available through multiple UK stockists
- Refrigerated storage until dispatch
Critical Analysis: DoNotAge excels at marketing itself as more than a supplement company, but this "research organisation" positioning comes with a premium price. Their 99.8% purity claims are impressive, yet they charge £55 for the same 2-month NMN supply we offer for £39.99. The refrigerated storage is a nice touch, but questions remain about whether this justifies the 38% price premium over comparable quality options.
Best For: Those who value brand prestige and don't mind paying extra for marketing-driven positioning.
3. VivaNMN
UK Family-Owned Specialist
A family-owned UK business focused specifically on high-quality NMN supplementation with strong customer satisfaction.
Key Products:
- Pure NMN (500mg) - £35-45 for 30 capsules (1-month supply)
Strengths:
- UK manufactured with fast, reliable delivery
- Good customer reviews (4.7 stars on Trustpilot)
- Simple, focused product range
- 100-day money-back guarantee
- Responsive customer service
- Family-owned authenticity
Critical Analysis: VivaNMN offers solid quality and customer service, but their single-month supply model means higher ongoing costs. At £35-45 monthly, you're paying £70-90 for a 2-month supply versus our £39.99. Their standard capsules also lack delayed-release technology, potentially compromising absorption. While their customer service is excellent, the value proposition doesn't compete with multi-month supplies from quality competitors.
Best For: Customers who prefer supporting family businesses and don't mind paying more for smaller quantities.
4. Vitality Pro
Premium UK Testing Standards
A UK company emphasising third-party testing and quality control, with ISO 9001 certification and comprehensive longevity range.
Key Products:
- NMN (500mg) - £60 for 60 capsules (2-month supply)
- NMN + Resveratrol blend - £70-80
- Individual longevity compounds - £50-120
Strengths:
- Extensive third-party testing with certificates available
- ISO 9001 certified UK company
- Uses Uthever® NMN (clinically tested)
- Professional healthcare practitioner endorsements
- 60-day satisfaction guarantee
- Delayed-release capsules
Critical Analysis: Vitality Pro delivers genuine quality with proper delayed-release technology and clinical-grade ingredients. However, their £60 price for the same 2-month NMN supply we offer at £39.99 represents a 50% premium. While their ISO certification and healthcare endorsements add credibility, the question remains whether these certifications justify such significant price differences for fundamentally similar products.
Best For: Healthcare professionals and customers who prioritise certifications over value.
5. LongevityBox
Established UK Longevity Pioneer
One of the earlier UK companies to focus specifically on longevity supplementation, offering a comprehensive range of cutting-edge compounds.
Key Products:
- Ultra Pure NMNH - £50-70 for various sizes
- Senolytic blends - £60-80
- Individual compounds (Spermidine, Urolithin A) - £45-80
Strengths:
- Comprehensive longevity product range beyond just NMN
- UK-based operations with good customer service
- Third-party testing for purity
- Educational content and established reputation
- Focus on newer compounds like NMNH
Critical Analysis: LongevityBox's strength lies in their comprehensive range, but this becomes a weakness for focused supplementation. Their NMNH positioning as "superior to NMN" lacks substantial human research backing, yet commands premium pricing. For basic NMN needs, their £50-70 pricing for standard supply sizes doesn't offer compelling advantages over more focused, value-driven alternatives.
Best For: Longevity enthusiasts wanting access to experimental compounds and willing to pay for variety over value.
6. London Vitality
Self-Proclaimed "#1 UK Brand"
A newer UK brand claiming to be the country's leading longevity supplement provider, focusing on competitive pricing.
Key Products:
- NMN (500mg) - £25-35 for 30 capsules (1-month supply)
- NMN + Resveratrol - £40-50
Strengths:
- Competitive pricing structure
- UK-based with fast delivery
- 100-day returns policy
- No fillers or binders claimed
- Express next-day delivery
Critical Analysis: London Vitality's "#1 UK brand" claim is bold but unsubstantiated. While their £25-35 monthly pricing seems attractive, it translates to £50-70 for a 2-month supply—still more expensive than our £39.99 option. Their lack of delayed-release technology and limited third-party testing transparency raises questions about whether their budget positioning compromises effectiveness. The aggressive marketing claims don't align with their relatively short market presence.
Best For: Price-conscious customers willing to try newer brands with limited track records.
What Sets Us Apart
While all these brands offer longevity supplements, we provide the optimal combination of quality, science, and value:
Unmatched Quality-to-Price Ratio
We believe premium quality shouldn't require premium pricing. Our pharmaceutical-grade standards match the most expensive brands, but our direct-to-consumer model keeps costs reasonable.
Advanced Delivery Technology
Our delayed-release capsules protect NMN from stomach acid degradation - crucial for bioavailability. Many competitors still use standard capsules, wasting much of the active ingredient.
Complete Transparency
Every product comes with detailed ingredient information and third-party testing results. No proprietary blends hiding ingredient amounts or quality.
Science-First Philosophy
We formulate based on peer-reviewed research, not marketing trends. Every ingredient serves a specific, evidence-backed purpose.
UK-Focused Service
As a UK-based company, we understand our customers' needs and provide responsive, knowledgeable support without international complications.
Customer-Proven Results
Our reviews consistently mention real improvements in energy, focus, and vitality - not just satisfaction with packaging or delivery.

The Bottom Line
The longevity supplement market offers many options, but quality, transparency, and value vary dramatically between brands. We consistently deliver pharmaceutical-grade quality at fair prices, making premium longevity supplementation accessible to everyone.
Our commitment to science-based formulations, advanced delivery technology, and complete transparency has earned the trust of thousands of customers who report real improvements in their energy, focus, and overall vitality.
