Our Longevity Stack is engineered to support cellular energy, metabolic function, and healthy ageing at a comprehensive, system-wide level.

Built as a synergistic combination of three advanced formulations — Longevity+, NMN, and Reservatol — this stack targets the core biological pathways involved in how your body produces energy, protects cells, and maintains long-term performance.

At its foundation is NMN (Nicotinamide Mononucleotide), a key precursor to NAD+, supporting cellular energy production, mitochondrial function, and metabolic efficiency. This is paired with Reservatol (Resveratrol 600 mg, 50% extract), a powerful antioxidant that supports cellular protection, oxidative stress management, and overall cellular resilience.

Completing the stack is Longevity+, formulated with compounds such as quercetin and additional plant-based actives that support cardiovascular function, metabolic health, and cellular defence pathways.

Together, these formulations work in synergy to support energy at a cellular level, protect against age-related decline, and maintain overall physiological function over time.

Our Longevity Stack is designed for daily use to support cellular performance, resilience, and long-term health.

The Science

Evidence-Based Formulation

Every product in the Longevity Stack is selected based on peer-reviewed clinical research — NAD+ precursors, sirtuin activators and senolytic compounds working together to support cellular energy, metabolic health and healthy aging.

Benefits

  • Directly increases NAD+ levels and cellular energy production
  • Activates sirtuin longevity pathways
  • Reduces oxidative stress and inflammatory markers
  • Supports mitochondrial function and cellular repair
  • Contributes to healthy cognitive and cardiovascular aging

Why our Longevity Stack

Individual longevity compounds each target one mechanism. The Longevity Stack layers three complementary approaches: NMN at 500mg to directly fuel NAD+ biosynthesis via the Nampt salvage pathway, Resveratrol at 500mg to activate sirtuins and AMPK, and Longevity+ to address the broader cellular picture — senolytic activity, mitochondrial support and oxidative stress. The compounds work synergistically: NAD+ availability potentiates sirtuin activation by resveratrol, creating a combined effect greater than any single ingredient.

The Experience

What you'll feel

  • More sustained energy
  • Sharper mental clarity
  • Stronger NAD⁺ production
  • Improved cellular repair
  • Greater muscle endurance
Week 1 14%

NAD⁺ loading

NMN begins directly elevating cellular NAD⁺ levels. Resveratrol and longevity compounds are establishing their baseline. Some notice a subtle but clean energy lift within the first week.

Week 2 28%

Cellular energy

Mitochondrial efficiency improves as NAD⁺ rises and sirtuin activation increases. Energy feels more sustained and less dependent on stimulants.

Week 3 42%

Mental sharpening

Cognitive clarity and focus improve as cellular energy metabolism optimises across brain tissue. Mental fatigue becomes less pronounced.

Week 4 54%

Endurance building

Muscle endurance and physical performance improve. NAD⁺-driven ATP production and reduced oxidative stress are now supporting training output.

Week 6 68%

Repair accelerating

Cellular DNA repair processes are meaningfully upregulated. Senolytic activity from quercetin and fisetin is clearing aged and dysfunctional cells.

Week 8 80%

Anti-ageing momentum

NAD⁺ levels are now substantially elevated. Energy, cognition, and cellular repair are all operating at a meaningfully higher level.

Month 3+ 95%

Your longevity floor

Long-term cellular NAD⁺ support is established and maintained. Keep supplementing — the anti-ageing and performance benefits accumulate over years.

This is now my non-negotiable daily supplement stack. NAD+, Resveratrol and NMN — it's a serious formula for anyone who takes their long-term health seriously. Feel sharper and more energised.

The NMN and Longevity+ combination feels really powerful. Energy, focus and recovery have all improved. This is the kind of stack that makes a real difference over time.

The ingredients across all three products are exceptional. Everything is properly dosed and research-backed. At this price for what you're getting it's genuinely excellent value.

The most comprehensive longevity stack I've found. NMN, quercetin, fisetin and resveratrol all together at proper doses is exactly what research-backed longevity supplementation should look like.

Three months in and the difference in energy, mental clarity and general vitality is really significant. I feel like I've turned the clock back in some meaningful way.

I've been following the longevity science closely for years and this stack is impressively well-researched. The inclusion of NMN alongside Longevity+ shows real synergistic thinking.

The NMN and resveratrol synergy is obvious. Energy is more sustained, recovery is faster and my thinking is sharper. The sirtuin activation stack is working.

Really excellent quality. The NMN at 500mg is the correct research dose — most products underdose to cut costs. This is done properly.

Eight weeks in and my sleep quality, energy and general resilience have all improved. This is the kind of stack that makes a real difference over years of consistent use.

The ubiquinol form of CoQ10 in Longevity+ is the superior bioavailable form — good to see it used rather than cheaper ubiquinone. Every detail of this stack shows quality thinking.
