⚡ What Is NMN?

Nicotinamide Mononucleotide (NMN, CAS 1094-61-7, molecular formula C11H15N2O8P, MW 334.22 g/mol) is a naturally occurring nucleotide found in all living cells. It is a ribonucleotide — a monophosphate form of nicotinamide riboside — and a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide). NMN is found naturally in foods including broccoli, edamame, avocado and cow's milk, but only in trace quantities — impractical to obtain clinically relevant amounts from diet alone. NMN is absorbed in the small intestine via the dedicated Slc12a8 transporter. No authorised EU/UK health claims. Educational background only — food supplement, not a medicine.

🧬 NAD+ — Why It Matters

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme involved in over 500 enzymatic reactions across all cell types. Its primary roles include: the mitochondrial electron transport chain (cellular energy production via OXPHOS), DNA repair via PARP enzymes (poly-ADP-ribose polymerase), sirtuin activation (SIRT1–7 — the longevity-associated proteins studied by Sinclair, Guarente and others), and calcium signalling via CD38. NAD+ levels decline significantly with age — by approximately 50% between ages 20 and 50 in both human and animal studies. NMN supplementation has been documented in multiple human RCTs to raise blood NAD+ levels. Educational background only — food supplement, not a medicine.

📊 What the Research Shows — Honestly

Human clinical research on NMN has grown substantially since 2020. Key studies: Irie et al. (2020, NPJ Aging) — first human NMN RCT; 250mg/day NMN safe and elevated blood NAD+ metabolites in healthy women. Yoshino et al. (2021, Science) — 250mg/day NMN for 10 weeks in postmenopausal women improved muscle insulin sensitivity. Igarashi et al. (2023) — 300/600/1,200mg/day NMN in amateur runners; 600–1,200mg groups showed increased VO2 max and oxygen uptake after 6 weeks. Yi et al. (2023) — 300/600mg NMN raised NAD+ in blood, saliva and urine over 60 days. Important caveat: most human NMN trials are small, short-term and of variable quality. Long-term human evidence is still developing. We state this honestly. Educational background only — not health claims. Food supplement — not a medicine.

🔬 Why 700mg — The High-Strength Rationale

Clinical studies have used NMN doses from 250mg to 1,200mg per day. The 250mg baseline dose in early human RCTs demonstrated NAD+ elevation and initial metabolic signals. Higher doses — 600mg and 1,200mg — showed stronger VO2 max improvements in the Igarashi 2023 runner study. 700mg per capsule provides a high-strength dose within the range of the higher-dose clinical protocols, whilst remaining in a single capsule for those preferring one-capsule convenience. Many NMN products marketed as "high strength" contain 250–500mg per capsule with fillers diluting the fill weight. Our NMN 700mg capsules contain 700mg pure NMN with zero fillers — confirmed by Eurofins at 99.99% purity. Educational background only — food supplement, not a medicine.

🚫 No Fillers — In-House Encapsulated

NMN powder encapsulates cleanly without requiring flow agents. Contract manufacturers add fillers like Microcrystalline Cellulose (MCC) or Dicalcium Phosphate (DCP) to improve powder flow through industrial filling machines — at the cost of displacing NMN. Because Charge Products encapsulates in-house at our own 5 Star FSA rated Essex facility, our NMN 700mg capsules contain exactly two ingredients: NMN and the vegan HPMC capsule shell. No MCC. No DCP. No Magnesium Stearate. No silicon dioxide. 700mg of pure NMN per capsule — not 700mg of NMN mixed with fillers. Big Idea Services Ltd, Co. No. 11645389.

NAD+ levels decline with age. NMN is converted to NAD+ in the body via the Slc12a8 intestinal transporter. No authorised EU/UK health claims. Educational background only — food supplement, not a medicine.

What does 99.99% purity mean?

99.99% purity means 99.99% of each capsule's fill content is Nicotinamide Mononucleotide — with less than 0.01% other substances. This is independently confirmed by Eurofins, an internationally accredited third-party analytical testing laboratory — not self-declared. CoA available on request. Food supplement — not a medicine.

How can I test if my NMN is pure?

Three home tests: (1) Weight — a pure 700mg NMN capsule should weigh 790–820mg on a digital scale; significantly heavier = fillers. (2) Taste — pure NMN has a clean, zesty, lightly citrus-like taste; flavourless = fillers; bitter/harsh = possible B3 Nicotinamide substitute. (3) Dissolve — pure NMN dissolves cleanly in water within 30–60 seconds; slow dissolve/clumping/milky residue = fillers. Full guide at chargeproducts.co.uk/blogs/news/best-nmn-supplement-uk.
