500mg · Acid-Resistant HPMC · GMP UK

A high-purity β-Nicotinamide Mononucleotide supplement in an acid-resistant capsule— formulated to protect the ingredient through the stomach and support absorption in the intestine.

Pharmaceutical-grade (>98% purity)
Batch tested for purity
100% vegan — no fillers, no binders
Certificates of Analysis published
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.

Why Most NMN Supplements Fall Short

The ingredient on the label is only part of the story. How it's delivered determines how much reaches your system.

✕ Standard Gelatin or Cellulose Capsules

Standard capsules dissolve quickly in the stomach (pH 1.5–3.5). At this acidity level, NMN is exposed to conditions that can degrade the ingredient before it reaches the small intestine — the primary site of absorption. You may be paying for a full dose but not getting one.

✓ Our Acid-Resistant HPMC Capsule (Size 00)

Our capsule shell is made from Hydroxypropyl Methyl Cellulose — a plant-based polymer that is designed to remain intact through the low-pH environment of the stomach. It dissolves later, in the intestine, releasing the full 500mg dose where absorption can occur. This is the same enteric-delivery principle used in pharmaceutical formulations.

What's Inside & What It Supports

NMN is a naturally occurring compound and a direct precursor to NAD⁺ — a coenzyme involved in fundamental cellular processes.

1

NAD⁺ Precursor — One Conversion Step to NAD⁺

NMN is one metabolic step away from NAD⁺ (Nicotinamide Adenine Dinucleotide). Unlike other Vitamin B3 derivatives, it does not require multiple conversion stages, making it one of the most direct nutritional precursors available.

2

Supports Normal Energy-Yielding Metabolism

NAD⁺ plays a central role in how cells convert nutrients into usable energy. As a Vitamin B3 derivative, NMN contributes to the normal function of metabolic energy pathways — a well-established role of the B vitamin family.

3

Supports Normal Cell Division & DNA Maintenance

NAD⁺ is a cofactor used by enzymes involved in DNA repair and cell maintenance processes. Niacin (Vitamin B3), of which NMN is a derivative, contributes to the maintenance of normal DNA — a permitted EU/UK nutrient function claim.

4

Pharmaceutical-Grade Purity — Verified by an Independent UK Lab

Every batch is tested for identity and purity before it leaves the manufacturer. We publish these Certificates of Analysis publicly — no request needed. >98% pharmaceutical-grade NMN, nothing added.

5

Completely Clean Formula

No magnesium stearate. No silicon dioxide. No titanium dioxide. No fillers, binders, or flow agents. The only two ingredients in this product are the NMN and the HPMC capsule shell. Nothing else.

Who This Is For

🔬

The Research-Led Supplementer

You've read the studies. You want a formulation built around bioavailability and transparency — not marketing claims.

🧬

The Proactive 30+ Individual

NAD⁺ levels are known to decline with age. You're taking a considered, science-backed approach to maintaining long-term cellular function.

The High-Performer

You need your supplements to work. You're not interested in a product where half the active ingredient gets degraded before it's absorbed.

🌿

The Clean-Label Purist

You read ingredient lists. You reject products with unnecessary additives. This formula has two ingredients: NMN and the capsule shell.

Understanding NMN & NAD⁺

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell. It plays a central role in two fundamental processes: converting food into cellular energy and supporting enzyme activity involved in DNA maintenance.

Research in this field consistently demonstrates that NAD⁺ levels in the body decline with age. NMN — as a direct precursor — is efficiently converted into NAD⁺ by the body, and has been studied as a method of supporting NAD⁺ levels nutritionally.

Comparing NAD⁺ Precursors

NMN This Product Direct Precursor. One enzymatic step to NAD⁺. Used in clinical human studies demonstrating increases in blood NAD⁺ levels.
NR (Nicotinamide Riboside) Indirect. Must first be converted to NMN in the body before becoming NAD⁺ — an additional conversion stage.
Niacin (Vitamin B3) A much earlier precursor. Requires multiple conversion steps and commonly causes a "flushing" side effect at functional doses.

Evidence & Research Context

We present what the research actually shows — including its limitations. We don't overclaim.

✓ Established in Research

  • Human trials confirm NMN supplementation increases blood NAD⁺ levels.
  • Well tolerated in healthy adults at 500mg daily doses in short-to-medium term studies.
  • Oral bioavailability confirmed; NMN is absorbed and converted in human subjects.
  • Enteric-release delivery shown to improve intestinal bioavailability of sensitive compounds.

⚠ Still Under Investigation

  • Long-term human safety data beyond 12–24 months remains limited.
  • Optimal dosing by age, lifestyle and individual variation not yet established.
  • The magnitude and clinical significance of specific outcome benefits in humans is still being evaluated.

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?
Every manufactured batch is tested for identity and purity before it is dispatched. The Certificate of Analysis (CoA) for each batch is published publicly on our website. You can verify the batch code from your product at any time.
Why acid-resistant HPMC instead of standard capsules?
Standard cellulose or gelatin 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."
