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

NAD+ is one of the most important molecules in your body. It powers cellular energy, supports DNA repair, and keeps your mitochondria running efficiently. The problem? Your NAD+ levels drop significantly as you age — by up to 50% between your 40s and 60s.

Cell One delivers 250mg of pharmaceutical-grade NMN (Nicotinamide Mononucleotide) per capsule — the most direct and bioavailable precursor to NAD+. Unlike nicotinamide riboside, NMN sits just one enzymatic step away from NAD+ in your cells, meaning faster and more efficient conversion.

We source our NMN from a GMP-certified facility and every single batch is independently tested by a third-party lab using HPLC analysis. The result: verified purity above 99%, with a Certificate of Analysis available for every lot we produce.

Most of our customers notice improved energy and mental clarity within the first two to four weeks. For best results, we recommend taking one to two capsules daily with your morning meal. Pair it with Sirtuin One for enhanced longevity signalling, or add Calm One to preserve your NAD+ levels overnight.

This is the foundation of everything we build. Start here.

• 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

Take 1–2 capsules daily with your morning meal. For enhanced absorption, take with a small amount of fat. Start with 1 capsule (250mg) for the first 2 weeks, then increase to 2 capsules (500mg) if desired. Do not exceed 4 capsules per day.

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.
