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…
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

Brilliant NMN Supplements
Since I started taking these around 3 months ago, I feel that I have more energy and don't seem to flag early afternoon anymore. This company feels very personable, they keep in touch quite regularly too

"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 noticed a massive increase in energy and just a general feeling of feeling better in myself. After about 3-4 weeks I was driving in ky car and thought to myself flipping heck I feel great!

Have used these supplement for a few years and never miss a month . Recommend for menopause
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.
Great sleep
Great sleep, more energy and generally feeling better since I started taking this supplement. Never had any issues I have a subscription that gets delivered every three months. I would recommend this product.
Fast delivery and a great product
Fast delivery and a great product. Most notable difference is a reduction in aches and tenderness on days after training. Sleep is also improved.
