"I'm on my second bottle now. Didn't notice much at first, then realised I wasn't feeling as tired in the afternoons. That's been the biggest change for me."

"Love using this. I feel more awake and less foggy, especially in the mornings. It's subtle, but enough that I've already ordered again."
About
Built by someone who needed it to work.
RGENR8 started because the existing NMN options on the UK market were either underdosed, overpriced, or shipped from somewhere we couldn't trace. So we made the supplement we wanted to take ourselves.

FAQ
Questions, answered.
How do I take RGENR8 NMN Pro?
One capsule daily, ideally with breakfast. Each bottle contains a 30-day supply.
Is RGENR8 third-party tested?
Yes. Every batch is independently tested for NMN purity (≥99%) and absence of contaminants by an accredited laboratory. Certificates available on request.
How does the subscription work?
There are two plans. The 3-month plan sends 90 capsules every 3 months for £34.99, and your first delivery is £27.99 with the welcome discount (31p a day). The monthly plan sends one bottle a month for £22.95. On either plan you can switch plans, change your address or cancel any time in your customer portal, with no calls or emails.
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 NMN legal to buy in the UK?
Yes. NMN is openly bought and sold across the UK. It is not banned, not a controlled substance and not prescription-only. It also holds no novel food authorisation in Great Britain. Both of those statements are true at the same time, which is why coverage of NMN's legal status often reads as contradictory. RGENR8 sells Pure NMN as a food supplement, makes no authorised health claims, and states this plainly rather than working around it.
