NMN is working well for me
NMN is working well for me. I have been taking it just shy of 4 months and have noticed that I dont seem to get the afternoon slumps that used to plague me everyday. I wouldn't say im jumping through hoops yet, but I have other health issues to contend with. But overall a definite improvement. The company is great and are very quick to assist in any queries and always so polite.

I'm 3 weeks in now and I can definitely tell the difference. I can wake up and get straight out of bed and I have much more energy, not just in the mornings, but I don't feel the "slump" I would feel in the afternoon. Definitely keeping this as part of my morning routine
Great service and a great product

I've been using VivaNMN for well over a year now and my energy levels are incredible, considering my health conditions. I have found that my skin has never been so soft and no spots or blemishes since I started using VivaNMN. My sleep pattern is so much better and no wakening 2 or 3 times through the night. I've convinced several friends to try VivaNMN and they now repeat customers. I continue to spread the word to everyone I talk to about it. Long may it continue

Have been taking these for three weeks and I've noticed the difference in my focus, energy and all-round motivation. Have tried various different things like lions mane and never persevered but love the app and it keeps me on track, I am in for the duration and I am signed up monthly. I would totally recommend these. Great all round experience
I've been taking Viva NMN for over six…
I've been taking Viva NMN for over six months now, and in my experience the benefits really start to show after one to two months of consistent use.
The improvements have been noticeable, better focus, stronger concentration, improved mood, sharper memory, and an overall sense of positivity. It genuinely feels like you're functioning at a higher level.
I took a month off to see whether NMN was actually contributing to these changes, and I immediately noticed a drop in all of the above. Now that I'm two months back on it, those benefits have returned and continue to build.
I am a male age 49.
Based on my experience, I would definitely recommend Viva NMN.
More energy, better sleep and better looking skin!
I've been taking it for a while and really feel the difference. My dad also takes them and says he has more energy and a better sleep.
I'm moving out of the UK but would love to continue taking it, I hope VIVANMN can arrange a delivery...

"It can't be a coincidence that I am sleeping better and feel happier and calmer since starting NMM (I am almost 3 weeks into my first bottle). I take a lot of vitamins so was wary to give NMM the credit but this is the only addition to my daily vitamin intake and the only major change, and I must say that I feel good

"My son suggested I take NMN capsules and you'll really feel the effect of them on a day to day basis, I am 83 years old and have a few health issue, I have been taking a capsule a day for nearly a year now and I must admit I do feel better from using them."

I have been using these since November…
I have been using these since November 2024. I have CFS/ME and Fibromyalgia, one of the main symptoms of both of these conditions is extreme fatigue. I do believe that these tablets have increased my ability to do more around the house than I have done since 2011 and having spine surgery. I’m still disabled and mostly housebound but I have times where I can do more little jobs which is amazing. I will continue to take them for as long as I am able to and while I can see the difference they make to me. I have them automatically delivered every month.
