What is NMN, and why does it matter after 35?
NMN is nicotinamide mononucleotide, a direct precursor to NAD+, the molecule your cells use to turn food into energy and to run repair. NAD+ falls as you age, and that decline tracks the things people actually notice: the afternoon slump, slower recovery, sleep that stops doing its job. An NMN supplement is the most direct way to put it back, in one enzymatic step.

Our standards
The standard behind every formula
Every NMN and NAD+ supplement we make is produced in the UK, dosed against the published research, and tested batch by batch. Some of that research is ours.
Research we published, not research we borrowed
In 2023 our founder co-authored a paper in Cell Reports on what happens inside a human neuron when NAD is depleted. That finding is why NAD+ Brain exists. Most supplement brands cite other people's science. This one started with ours.
Read the paperAn ongoing university collaboration
We work with Dr Sovan Sarkar at the University of Birmingham, whose lab studies autophagy and NAD metabolism in human stem-cell models. The relationship is ongoing, not a one-off citation.
Meet the scientistsEvidence-led ingredients
Every ingredient is chosen against human research, and we say which. If the evidence is animal or cell work, we say that too.
Considered dosages
Formulated around the doses used in the studies, not the dose that makes a label look impressive. In addition, NMN Bio has licensed a proprietary AI software that helps us see ingredient-to-ingredient interaction and model in silico a blend-to-human interaction when we formulate a new product.
Made in the UK
Produced in a GMP-certified UK facility, batches produced quarterly, so nothing sits in a warehouse degrading.
Independently tested, every batch
Identity, purity and contaminants, checked by an independent laboratory before release. Your batch certificate is emailed to you after you order.
Customer reviews
What customers notice.
The consistency is what made me reorder
“I had previously tried a cheaper NMN product and felt very little. With NMN Bio, I began noticing more alertness and energy after the first week. The third-party testing and UK manufacturing were what convinced me to try it, but the consistency is what made me reorder. I’ve been on monthly subscription for over a year, and this is my go to supplement for maintaining my energy levels.”
NMN 500 mg
An essential part of my morning routine
“The difference in my mental sharpness between before and after starting NAD+ Brain has been noticeable. After taking it consistently for 2 weeks, I noticed an increase in my productivity, like the baseline of focus is now elevated. Combining it with NMN has become an essential part of my morning routine.”
NAD+ Brain
I do not feel groggy the following morning
“I had no trouble falling asleep, but I regularly woke during the night and struggled to switch off again. After taking Oh!Mg consistently for a few days, I could see my Whoop tracking more deep and REM sleep. Most importantly, I do not feel groggy the following morning.”
Oh!Mg Magnesium PM
Easy to take and combine well with NMN
“I originally purchased TMG after reading about methylation support. What made me continue was an effect on focus and concentration. The capsules are easy to take and combine well with NMN.”
TMG
A permanent place in my routine
“I exercise outdoors regularly and wanted additional support for recovery and seasonal comfort. After a couple of days, I could breathe much better. It has earned a permanent place in my routine alongside NMN.”
Quercetin + Vitamin C
I am more in control
“This has not replaced eating well or exercising, but it has complemented both. Over about 3 weeks, I noticed a change in my appetite, like I am more in control. I would recommend tracking results rather than expecting an overnight transformation.”
Berberine + Milk Thistle

Built to make longevity science more useful
NMN Bio was founded in 2020 by Dr Elena Seranova, a PhD stem-cell biologist, to turn emerging NAD+ research into supplements people can actually use. After researching NAD+ metabolism and neurodegeneration at the University of Birmingham for years, she saw an obvious gap in the market for a reliable supplier of NMN, NAD+ and longevity supplement brand people can trust.
