You’ve probably seen NAD+ mentioned alongside things like longevity, metabolism, or even biohacking. But what exactly is it, and why are so many people in their 30s, 40s, and 50s now paying attention?
Let’s break it down.
“By my mid-40s I just assumed energy dips were part of life. But within two weeks of adding this NAD+ and longevity supplement, I noticed a real shift, clearer focus, better sleep, and I’m finally not dragging through my workouts. Feels like I turned the volume back up.”
NAD+ used to be a niche term in aging research circles. Now? Athletes, entrepreneurs, and everyday high-performers are tapping into its benefits. Think of it as the fuel that helps your cells do their job better, especially as you start to notice energy dips in your late 30s and 40s.
By age 40, your natural NAD+ levels can decline by up to 50%. That can mean slower recovery, more brain fog, and a subtle but persistent drop in drive. Replenishing it might just help you feel like you again.
NAD+ LEVELS DROP BY UP TO 50% BY AGE 40, IMPACTING ENERGY, RECOVERY, AND CELL REPAIR.
RAISING NAD+ SUPPORTS MITOCHONDRIA, DNA REPAIR, AND METABOLIC HEALTH, KEY TO FEELING AND PERFORMING YOUNGER.
NAD+ is essential for mitochondrial function (aka your cellular battery). That makes it a direct player in how energised, mentally sharp, and physically resilient you feel. It’s not hype, your body literally can’t function without it.
“Running a business and raising kids takes it out of you. This helped stabilise my energy and mental clarity without needing to lean on caffeine. I feel sharper at work, and less wrecked at the end of the day.”
Trying to stay lean as you get older? NAD+ is deeply involved in how your body handles glucose and fat. Unlike caffeine or thermogenics, NAD+ supports metabolism at the cellular level, without the crash.
In my private practice, one of the most common questions I’m asked is, “What exactly is NAD+ and why does everyone in longevity care about it?” Most people have heard of it, but don’t realise how central it is to energy, repair, and healthy ageing. I believe anyone serious about long-term health and performance should understand how NAD+ works, and the simple, proven ways we can support it daily.
Brain fog. Memory slips. Low motivation. These might not be “just aging.” NAD+ helps support neural repair, cognitive sharpness, and mental clarity, especially when you’re juggling career, family, and workouts all in one day.
“I do strength and BJJ twice a week, and I was feeling recovery get slower in my 40s. I’ve been taking MUTO Longevity consistently for 6 weeks and recovery is noticeably better. No soreness hangover, and I’m back in the gym faster. Legit difference.”
Sleep, strength training, fasting, cold exposure, NAD+ works in tandem with these longevity habits. But even if your routines aren’t dialled in 100%, NAD+ can help your cells stay more resilient under stress.
In the same way people now track their HRV or wear a Whoop, NAD+ is becoming a new baseline for proactive health. Not because it’s trendy, but because the science is finally catching up to what early adopters have already figured out.
You don’t need to be a biohacker to care about NAD+. You just need to care about your energy, performance, and long-term health.
The best part? Boosting NAD+ is simpler than you think.

Just over a week into Muto and i'm already feeling more energised and have seen an increase in my mood. I've been waiting for the launch of these for a while and after the first week, it's clear it was worth the wait! Excited to see the long term benefits!
I’m a couple weeks into my Muto journey and already feel the benefits. I feel like I have more energy and a clearer mind. Over the past couple weeks I’ve felt more motivated and focused. It’s helping massively towards achieving work and fitness goals.
A great addition to my regime; already seeing a difference very quickly to some of my recovery markers, especially HRV.
I’ve seen immediate improvement in my HRV since using Muto - game changer!
I've been taking Muto for 2 months and my HRV is higher than it's ever been. I've tried many products as part of my recovery from CFS and this has had by far the biggest impact on HRV. My recovery post exercise is quicker and I'm generally feeling stronger.
I’ve been using Muto for just over a month now and I’m honestly really impressed. I track all my data with a Whoop band, so I’ve got some solid numbers to back up how I’m feeling.
In the first 4 weeks:
My HRV went up by 32%, my resting heart rate dropped by 7% and my average recovery score improved by 26%
Considering I’ve already got my training, nutrition, and sleep pretty dialled in, seeing these kinds of improvements is actually pretty wild. Muto has definitely given my recovery that extra push and I’ve got considerably more energy throughout the day.
Also, Richie from the team gave me a call just to chat about my background and goals, which was a really nice personal touch you don’t see much these days.
Overall, it’s been a great experience so far and I’m excited to see how things keep progressing.
I started taking Muto a couple weeks ago, and I already feel great. Energy is high, focus is through the roof and I’m waking up full of motivation. Highly recommend!
Feel great
Has definitely helped my sleep and reduced my sugar cravings in the evening massively.
I was very sceptical about the claims made by Muto but decided to give it a go. I have been taking it for a month now and have seen slight raise in HRV . Resting heart rate has dropped from 65 to 55bpm and is consistently 55. Overall I believe this product does work and am gonna give it another month to see what it does. I would defo say give it a go .
Deffo feel like its changed my daily mood, energy and body
Since taking this supplement I’ve felt brand new. The cellular energy boost it gives you really enables me to power through my day. I take them first thing in the morning every day and can’t live without now.
Started using muto because I felt like my body couldn’t keep up with the amount of exercise I wanted to do. After taking muto, I felt more energised and ready for my next session! Great product!
Tracking through my Oura ring for the past two weeks HRV was up significantly after two days. Energy is up and staying consistent. Excited to keep tracking and see what the next few weeks bring.
I’ve only been taking MUTO a few weeks but can already notice the difference. I predominantly struggle with mornings but already feel myself finding these easier, having more energy throughout the whole day and feeling more focused.
