Day & Night Bundle — Your 24-Hour Longevity System
Most people treat energy and recovery as separate problems.
Science says they’re one cycle. Day and night, activation and repair, performance and restoration.
The Day & Night Bundle is built to optimise that cycle. It fuels your cells with NMN and NAD⁺ Brain in the morning to elevate energy, focus, and mitochondrial function, then restores balance in the evening with Oh!Mg Magnesium, our advanced magnesium complex that supports GABA activity and deep, natural sleep.
This is your complete longevity rhythm: energy that lasts through the day, recovery that restores through the night.
Whether you’re managing a demanding schedule, training intensely, or simply chasing optimal health, this system supports the cellular processes that keep your head clear, your body strong, and your cells resilient. Say goodbye to afternoon fatigue and bad sleep. Step into your optimal mental and physical capacity. Every day. On demand.
Morning: Activate.
Boost NAD⁺, sharpen your focus, and sustain your metabolism. Give your cells the fuel they need. Maximise physical and cognitive energy. You control the day. The day doesn’t control you anymore.
Night: Recover.
Oh!Mg Magnesium is like noise cancelling. For your thoughts, before going to sleep. So you can dream deeper, and restore better. Calm your nervous system, repair your cells, and reset for tomorrow.
Your longevity and performance isn’t built in hours — it’s built in cycles.Start mastering yours.
Customer reviews
What customers notice.
I’m not tired in the evenings anymore
“I started NMN because my energy was becoming noticeably less reliable, especially in the afternoon. After the first month, my boyfriend noticed that I’m not tired in the evenings anymore. The difference is not a stimulant rush; I simply feel more capable of sustaining my day, and not feeling the decrease in energy after 3pm.”
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
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
The focus developed gradually over weeks
“I’ve tried several nootropic formulas, but many relied on caffeine and simply made me feel overstimulated. NAD+ Brain felt different. The focus developed gradually over weeks, and I found myself drinking less coffee while still concentrating for longer.”
NAD+ Brain
The workday is finished!
“I’ve tried several magnesium products, and some either upset my stomach or seemed to do nothing. This formulation is different. I take it and feel relaxed within 20 minutes, no side effects. I can fall asleep faster and my body just knows from the berry scent that the workday is finished!”
Oh!Mg Magnesium PM
The most noticeable difference has been faster recovery
“I’m 42 and train 3 times a week. Since adding NMN 500 mg, the most noticeable difference has been faster recovery, and being able to push at every workout. I still do the fundamentals, but this has become one of the few supplements I take every morning without forgetting.”
NMN 500 mg
The effect feels steady rather than artificial
“This was not an overnight jolt, which I actually appreciated. Around week 2, I realised I was getting through the afternoon focus block without the usual mental dip or distraction. The effect feels steady rather than artificial.”
NAD+ Brain
Easier to wind down
“I train almost every day, and evening muscle tension was affecting how well I relaxed. Since using the magnesium by NMN Bio, I’ve noticed increased HRV and it’s easier to wind down, even after an evening workout. It is now one of the most reliable parts of my nighttime routine.”
Oh!Mg Magnesium PM
What I noticed was more practical
“I didn’t suddenly feel ten years younger. What I noticed was more practical: I wasn’t tired anymore. After stopping for 2 weeks, I noticed that I feel different, and exhausted at the end of the day, which convinced me it had been contributing more than I realised.”
NMN 500 mg
Part of both our routines
“My wife and I have been using NAD+ Brain for a few months now. She noticed how she doesn’t need to nap in the afternoon anymore, while I noticed more output in my accounting job, getting things done faster and not missing any deadlines, which is crucial in my line of work. It is unusual for us to agree on a supplement, but this has become part of both our routines.”
NAD+ Brain
Calming rather than sedating
“My partner and I both use Oh!Mg. It’s cool how I can almost feel the GABA increasing within half an hour or so, while my partner doesn’t get up to go to the bathroom in the middle of the night. We like that the effect feels calming rather than sedating and so much better than melatonin.”
