Susan M. 5/5
I’ve been taking these for three weeks and I can honestly say I’m feeling far less tired, sleeping better and generally have more energy. It’s early days, but I’m just about to make my next order. I’ve tried so many things to help with my menopausal tiredness and sleep issues, and I’m hoping I’ve finally found the solution!
Leigh B. 5/5
Been great, has given me focus and a level energy release throughout the day.
Andrew S. 5/5
I’m on my third week of NMN and have so much more energy than I have in a long time. I started to feel a difference after about 7 days and I’ve gone from strength to strength. I can highly recommend.

Kelly A. 5/5
Been taking this daily with a glass of water before my coffee. Loving the app and the handy tips/tasks to do each day. Feeling better with more energy and sleeping better too. Definitely would recommend 😁
Kate W. 5/5
I have noticed increased energy especially in the evening - this has helped with the gym and evening jobs I’d usually be too tired to do! Initially it took longer to get to sleep but now I’m week 3 I’m sleeping deeper.

Starting to feel some effects from it I don’t caffeine anymore in the afternoon I was seeing results in the gym until my injury but hopefully I will see more when I get back
Lewis H. 4/5
I switched brands to this one. I’m 58, and on a journey to better aging. I find I have some more energy and cognitive function seems improved. It’s early days but I’m hopeful.
Janet M. 4/5
This product works! My husband and i tried this before, we thought we'd felt benefits from it but we never appreciated it at the time. After the summer when the days felt shorter and i had no energy in the evenings I decided to try nmn again and wow, instantly felt better. Im able to get through my day with more energy, I feel more motivated for my 3x weekly evening exercise classes. I just feel different, better, and my hair also has felt the benefits. Feels thicker and healthier and dare i say it, less of the grey? Is this a thing? My husband noticed the difference in me and he's now back on it too with more energy and better sleep for him. Fast delivery by royal mail which i was able to track, no issues. 90 day supply which came compact in one bottle. I would highly recommend. If you've tried before you'll really notice the difference if you get back on it!

Into my 3rd week, my sleeping pattern has improved and no longer waking throughout the night. Also I feel more focused at work, which is amazing.

I feel awere already iv got more energy and get up and go.thank you
Mary M. 5/5
I went into taking NMN without knowing what it does or can do. I’m still in the dark really. But this is what I’ve seen after 3 weeks in…. 1. When I wake in the morning, I’m ready to just jump out of bed. I used to like a lie in and struggle to get up. Not anymore. 2. Feeling sluggish and tired in the afternoon. Not anymore. I could quite easily have an afternoon nap before. That feeling has gone away. 3. I like doing a 5k park run on a Saturday. Got my PB yesterday. Felt fantastic doing it. 4. Recovery after a run is also so much better. Felt ready to go again the next day… I’m not sure if this is what NMN is supposed to do. But it was I have been feeling. I’m a 54 yr old male and would definitely recommend.

Still waiting on any results
Sally M. 5/5
After initially having an upset stomach, when taking on an empty stomach things improved taking them with food. However, I’m not noticing anything other than consistent bloating!

Fiona A. 4/5
I’m on day 15 and can definitely feel a difference in my energy levels. I noticed a difference on day 12, I wasn’t tired at 2pm. This week I’ve come home from work and don’t need to sit down immediately.
Lisa 5/5
I’m about 6 weeks into a 3 month supply, taking a morning tablet has become part of my morning routine along with a coffee and collagen powder. Nearly 12 months postpartum and actually feeling great. Can I put it down to NMNs? I’m not sure yet, but I don’t want to stop to find out!
Gemma D. 5/5
One month in and I’ve really noticed a difference in my whole body. I’ll be in for the long haul, best I’ve felt in years and I truly mean it.
Tracy V. 5/5 Verified
I’ve been taking these for around a month, I can say my energy has improved, no longer needing a nap in the afternoon, even after a big night out and not being able to sleep til 4am. I was able to power through the afternoon and not succumbing to club nap. Really need to ask again in a my opinion on these
Sarah C. 4/5

Margo C. 5/5

Deborah M. 5/5

Amy L. 5/5
After 3 weeks I seem to have more energy
Gregory M. 5/5
Wake up feeling much brighter since I've been using this product;feel energised throughout the day
Darrin R. 5/5
Took about 7-8 days to see a difference. More alert and without feeling sluggish in the morning.
Tim T. 5/5
I started to feel the energy raise after a few days. I've been using NMN for 3 months now & have noticed that I've got new baby hair growing in my temple regions & when I was ready to colour my hair a few weeks ago, noticed that the new hair didn't need colouring. My new hair is my natural brown colour! My skin is looking more youthful and much less crepe style skin on arms and my muscle tone is better. Also the afternoon bloat is not there and I've lost weight without even trying. The me of 5 years ago is re-emerging.
Nicola D. 5/5 Verified
I must admit I was very sceptical & tried it as a last resort before going to my GP. Since taking one little capsule every morning within a week I no longer needed to sleep as soon as I finished work. Having a nap had become daily before taking this. I will order my next bottle!
Donna W. 5/5
Honestly, I’m so impressed with how I’ve been feeling since starting my NMN capsules! ✨💗 I’ve noticed such a difference in my energy levels, my skin looks brighter and fresher, and one of the biggest things for me is waking up in the morning without that foggy-headed feeling. I feel more switched on, refreshed and ready to take on the day! 🥰 It’s still early days, but I’m loving how I’m feeling so far and I’m excited to see how things go! ✨💫
