The science
NMN is a direct precursor to NAD+.
NAD+ is a coenzyme your body uses for cellular energy production and DNA repair. Cellular NAD+ levels decline with age. NMN (nicotinamide mononucleotide) is one of the most direct precursors your body uses to produce NAD+.
Human studies of oral NMN supplementation at doses from 100mg to 2,000mg a day have reported increases in blood NAD+ metabolites and improvements in markers of physical function in older adults. RGENR8 is 500mg a day, inside that tested range.

Questions
A few things people ask.
How do I take it?
One capsule daily, ideally with breakfast and a glass of water. One bottle is a 30-day supply.
How long before I notice anything?
It varies. Some people report feeling a difference within a few weeks; others take longer. We'd suggest taking it daily for at least 4 to 8 weeks before judging.
How does Subscribe & Save work?
Subscribe & Save ships a fresh bottle every month at £22.95 (versus £24.95 one-off), or 3 bottles every 3 months for £34.99. You can switch plans, change your shipping address or cancel any time via your customer portal.
How does the 14-day money-back guarantee work?
Send the unopened bottle back, in its original packaging with the seal unbroken, within 14 days of delivery and we'll refund the purchase in full. Opened or partially used bottles aren't eligible. Return shipping is the customer's responsibility.
Is RGENR8 Pure NMN worth it?
RGENR8 gives you a clean 500mg dose of NMN, a dose inside the range tested in published human trials, with no fillers and independent third-party testing, at £22.95 a month on subscription. If you want a single-ingredient NMN at a fair price with a verifiable Certificate of Analysis, it is a straightforward choice. Like all NMN, individual energy and recovery effects vary, so we suggest a fair 4 to 8 week trial.
What dose of NMN does RGENR8 use?
500mg of nicotinamide mononucleotide per capsule, taken once a day. It sits inside the 100mg to 2,000mg daily range tested in 25 published human trials.
How is RGENR8 NMN made and tested?
RGENR8 Pure NMN is made to GMP-equivalent standards and independently tested by an accredited laboratory. A Certificate of Analysis for your batch is available on request.
Is MNM the same as NMN?
Yes. "MNM" is a common misspelling of NMN, short for nicotinamide mononucleotide. RGENR8 Pure NMN is 500mg of NMN per capsule, single ingredient, £27.99 for a 3-month supply of 90 capsules on your first order with code WELCOME20.
Is RGENR8 the same as REGNR8RX, NMN Bio or Gener8?
No. RGENR8 is a UK NMN supplement brand. It is not REGNR8RX (a US prescription supplement), not NMN Bio (nmnbio.co.uk, a separate UK NMN brand), not Roll Recovery R8 (a muscle massage tool), and not Gener8 (gener8ads.com, a browser ad-rewards extension).
