NMN (Nicotinamide Mononucleotide) is a naturally occurring molecule and a direct precursor to NAD+, a coenzyme your cells use for energy production, DNA repair and other essential housekeeping work.

Your body converts NMN into NAD+. NAD+ levels naturally decline with age, and supplementing with NMN is one way to support those levels alongside diet, sleep and exercise.

NMN is not banned, not a controlled substance and not prescription-only in the UK, and you do not need a doctor's authorisation to buy it. It also holds no novel food authorisation in Great Britain, meaning it has not completed the safety assessment required before an ingredient is formally authorised for sale as a food supplement. The Food Standards Agency has issued no ban, withdrawal or recall, which is why NMN remains openly on sale from established UK brands. RGENR8 Pure NMN is sold as a UK food supplement, made to GMP-equivalent standards and batch-tested by an accredited laboratory. If you are pregnant, breastfeeding, taking medication or managing a health condition, speak to your GP first.

One capsule daily.

In the morning, ideally with breakfast. NMN works best on a consistent daily routine.

Not strictly required, but most people find taking it with breakfast easier to remember and gentler on the stomach.

NMN is generally well-tolerated. Very rarely, some people may experience mild digestive discomfort when starting any new supplement. If you have any concerns or are taking medication, speak to your GP. RGENR8 is not intended to diagnose, treat, cure or prevent any condition.
