Cell One - 60 x 99% Pure NMN for NAD+ 500mg Capsules

You used to bounce back from a hard week without thinking about it. Recovery was free. Then somewhere after 40, it stopped being free.

That change has a name in the research: NAD+ decline. And NMN is the most direct lever we have to support it.

What NAD+ does

NAD+ is the coenzyme behind cellular energy production, DNA repair, and the metabolic processes that keep every cell in your body functioning. Levels drop roughly 50% between your twenties and your fifties. You feel it as fatigue you can't quite explain, slower recovery, and a fade in mental sharpness.

How NMN supports it

NMN (β-Nicotinamide Mononucleotide) is the direct precursor your body uses to make NAD+. Take NMN, your body converts it into NAD+ through the salvage pathway. The biochemistry is straightforward. The doses used in human trials — and ours — are 250–500mg daily.

What's in each capsule

500mg of pharmaceutical-grade NMN at ≥99% purity. One capsule per serving. No proprietary blends, no synthetic colorants, no unnecessary additives. Hypromellose capsule, rice flour, nothing else.

Who it's for

Adults 40+ who want the foundational layer of a longevity routine. Anyone interested in supporting cellular energy at its source. People who prefer the cleanest single-ingredient formulation over a stack of marketing-driven blends.

How to take it

One capsule daily with your morning meal. NMN can be taken with or without food. Consistency over weeks and months is where the compounding effect lives — daily use is the point.

What to expect

Most people notice steadier energy through the day within two to four weeks. Recovery improvements typically follow in weeks three through six. Cognitive clarity often shows up first. Your body's response is yours — but the biology behind the support is well-documented.

Why we built it this way

Most NMN products sold today are dosed at 100–150mg. Enough for a label. Not enough for the outcome the research suggests. We build to the dose that the published trials used. That's the entire reason Vitra One exists.

• Restores declining NAD+ levels — the essential coenzyme your cells need for energy production, DNA repair, and healthy ageing
• Supports mitochondrial function by fuelling the electron transport chain, helping your cells generate energy more efficiently as you age
• Promotes DNA repair through PARP activation, protecting your genetic material from the cumulative damage caused by oxidative stress
• Enhances sirtuin activity by providing the NAD+ co-substrate that SIRT1–7 longevity proteins require to regulate inflammation and cellular defence
• Clinically studied in human trials — a 2022 Science paper confirmed significant NAD+ elevation within just 14 days at our recommended dose
• Pharmaceutical-grade purity verified above 99% by independent third-party HPLC testing, with Certificates of Analysis available for every batch
• Fast-absorbing and bioavailable — NMN is converted to NAD+ within minutes of oral ingestion, making it the most efficient NAD+ precursor available

β-Nicotinamide Mononucleotide (NMN) (≥99% purity) 500mg per capsule. Serving: 2 capsules (1,000mg). Other Ingredients: Hypromellose (Capsule), Rice Flour.

What is NMN and why does it matter?

NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+ — a molecule your body relies on for over 500 essential reactions, from energy production to DNA repair. As we age, NAD+ levels naturally decline. NMN helps restore them.

What does the research say?

A randomised, double-blind, placebo-controlled trial found that oral NMN significantly increased blood NAD+ levels in healthy adults within weeks, with participants also showing improvements in muscle insulin sensitivity and mitochondrial energy metabolism. Yoshino et al., Science, 2021 ↗

Research has also confirmed that NMN is rapidly absorbed and converted to NAD+ in human tissue — supporting its use as the most clinically validated NAD+ precursor available.

Why Cell One?

NAD+ decline is now recognised as one of the central hallmarks of ageing. López-Otín et al., Cell, 2013 ↗ Every batch of Cell One is independently tested via HPLC analysis to verify >99% purity — so you know exactly what you're getting.
