Pure NMN 500mg · Acid-Resistant HPMC · GMP UK

β-Nicotinamide Mononucleotide, precisely delivered

A high-purity NMN supplement in an acid-resistant capsule — formulated to protect the ingredient through the stomach and support absorption in the intestine.
Pharmaceutical-grade purity Third-party tested 100% vegan No fillers · No binders GMP UK-made
Why the capsule matters as much as the ingredient.

Most NMN capsules dissolve in your stomach before the ingredient can reach the intestine. Ours don't. Here's why that changes everything.

This is a food supplement. It is not intended to diagnose, treat, cure, or prevent any disease. Always read the label.

Why most NMN supplements fall short.

The capsule is not an afterthought. It determines how much of the ingredient actually reaches your system.

NMN supplement delivery system
Standard capsules

Dissolve in the stomach, where NMN can degrade before it reaches the intestine. You may be paying for a full dose but absorbing a fraction of it.

Our acid-resistant HPMC capsule

Stays intact through the stomach and dissolves in the intestine — where absorption actually occurs. The same enteric-delivery principle used in pharmaceutical formulations, in a 100% plant-based capsule.

What's inside and what it supports.

NMN is a naturally occurring compound your body uses to produce NAD⁺ — a coenzyme that declines with age and plays a role in energy and cell maintenance.

NMN formula ingredients
01

The most direct NAD⁺ precursor available

NMN is one step away from NAD⁺. Other precursors like NR or niacin require additional conversion stages before reaching the same point.

02

Supports normal energy-yielding metabolism

As a Vitamin B3 derivative, NMN contributes to normal energy metabolism — a permitted EU/UK nutrient function claim.

03

Supports normal DNA maintenance

Niacin (Vitamin B3), of which NMN is a derivative, contributes to the maintenance of normal DNA — a permitted EU/UK nutrient function claim.

04

Two ingredients. Nothing else.

NMN and the HPMC capsule shell. No fillers, binders, magnesium stearate, or flow agents.

Not for everyone. Here's who it's built for.

We'd rather you buy the right product than the wrong one.

Good fit

  • Adults 30+ taking a considered approach to cellular nutrition
  • Those who want a formulation built around bioavailability, not marketing
  • Anyone who reads ingredient lists and rejects unnecessary additives
  • Those who prioritise independently verified, UK-made quality

Not for you if

  • You are pregnant or breastfeeding
  • You are looking for a clinically prescribed treatment
  • You expect immediate stimulant-like effects
  • You are under 18

Why NMN, not NR or niacin.

NAD⁺ is a coenzyme found in every cell, involved in energy production and DNA maintenance. Levels decline with age. NMN is the most direct way to support them nutritionally.

NMN This product Direct precursor. One step to NAD⁺. Clinically studied; shown to increase blood NAD⁺ levels in humans.
NR (Nicotinamide Riboside) Must convert to NMN first — one extra step before reaching NAD⁺.
Niacin (Vitamin B3) Multiple conversion steps required. Often causes skin flushing at functional doses.

What the research shows — and what it doesn't.

We don't overclaim. Here's an honest summary of where the evidence stands.

Established
  • NMN raises blood NAD⁺ levels in human trials.
  • Well tolerated at 500mg daily in human studies.
  • Orally bioavailable — absorbed and converted in humans.
Still emerging
  • Long-term safety data beyond 12–24 months is limited.
  • Optimal dose varies by individual — not yet established.
  • Specific clinical outcomes in humans are still being studied.

UK Regulatory Notice — Novel Food Status

NMN is classified as a novel food in the UK and is available for purchase whilst under review for full authorisation by the FSA. This product is a food supplement. It is not intended to diagnose, treat, cure, or prevent any disease.

Simple to take consistently.

1 capsule (500mg) daily, with water. Most people take it in the morning. With or without food — the acid-resistant capsule protects the ingredient either way. Allow 4–8 weeks before assessing your response; NMN is not a stimulant.

Manufactured and tested to the standard we'd expect ourselves.

Every batch is made in the UK in a GMP-certified facility and independently verified before it ships.

Frequently asked questions.

When and how should I take NMN?
Take 1 capsule (500mg) daily with water. Most users take it in the morning, as NMN may interact with circadian signalling pathways. It can be taken with or without food — though some users prefer taking it alongside a small amount of healthy fat.
Is this product vegan?
Yes. Both the NMN ingredient and the HPMC capsule shell are 100% plant-derived and suitable for vegans.
Should I take TMG alongside NMN?
Some supplementation approaches pair NMN with TMG (Trimethylglycine), which acts as a methyl donor. Our Pure NMN is designed as a standalone product. We also offer an NMN Complex version that includes TMG for those who prefer the combination in one capsule.
How quickly will I notice anything?
NMN works by supporting underlying biological processes that are cumulative in nature. Individual experiences vary significantly. We recommend consistent daily use for at least 4–8 weeks before evaluating your personal response. It is not a stimulant and does not produce immediate effects.
How do you verify quality?
1. Identity and purity (CoA): Verifies the ingredient is NMN and >98% pure. View CoA →

2. Safety (third-party): Independent testing checks for heavy metals, yeasts, and moulds. View safety certificate →
Why acid-resistant HPMC instead of standard capsules?
Standard capsules dissolve rapidly in the stomach (pH 1.5–3.5), where NMN can be degraded before absorption. HPMC with enteric-coating properties remains intact through the stomach and dissolves in the more neutral environment of the small intestine — the primary site of nutrient absorption. This is designed to maximise the amount of intact NMN available for uptake.

Mathew Stuckey Founder, Longevity Formulas
"When we were formulating this product, the delivery system was the non-negotiable. We reviewed the degradation data on NMN in acidic conditions and it was clear: a standard capsule wasn't acceptable. We chose HPMC specifically because it's what the evidence pointed to — not because it was cheaper or easier. It wasn't."
