I feel much better since taking NMN
I. Have been using then for about two months now people are saying you look younger and asking if I have had any work done. I am 45 and now feel that I could get away with 35 if someone asked me 🤣🤣🤣
Without a doubt the best decision I made for myself. The difference in unbelievable in my daily lives fe
Excellent!
Delivery was fast but I can't comment on tablets I've only been taking a few weeks 🙂
I have taken NMN for months now and I feel energised generally.
Fab overall
I feel a little more energetic and my skin looks more clear
Love this product.
I’ve been taking this for nearly 2 months and definitely have more daytime energy. My thoughts seem to be more focused and clear. It’s also suppressed my appetite a little which is a great thing!
Been using now for a few months and can definitely see and feel a difference within my skin , hair and nails . Plus more energy
So far can’t comment as it’s only been a few weeks but looking forward to seeing some results
Feel clear and energised.
They gave me a boost without realising,your renewed energy. Id recommend them to anyone of my age or younger.
Been useing these tablets 4 months now felt flat every afternoon till I took these will I buy again for sure great product 👌
Iv been taking Viva Nmn for 2 months and I can honestly say I have more energy, I feel more focused and my sleep has been great. I would highly recommend
I couldn’t be happier with my experience. The ordering process was so quick and easy, straightforward and completely hassle-free. Delivery was incredibly fast, it arrived sooner than I expected which was wonderful! The product itself feels really high quality, presented beautifully, neat and professional, exactly as described. I feel confident taking it and would absolutely recommend. Thank you so much!
Amazing results for my nails and hair and skin health
My main reason for starting these capsules was to gain more energy as over the last few years I am extremely tired after work and dont have any energy left to do anything in the evening. I'm really encouraged that over the past week I have noticed that I am able to do more in the evenings. Fingers crossed this is the start of the new energised me! :))
I am finding great results - more energy and younger looking skin
Great product, speedy delivery, easy to swallow and the benefits can actually be felt.
Amazing product!
It’s helping no end. Feel more energised. I’m 58 and my morning routine is 9 tablets and 2 powders. Even take it on holidays. It’s true in your 50s your energy depletes trouble sleeping and when I got out of the shower in a hotel with a full length mirror i realised “ look at you your an old man” that was the wake up call !!! so I researched what happens to muscle mass, and other things. I lift heavy weights 3/4 times a week, long walks as running with both patella ligaments reattached is out. Feel and look better. Give it a try, take it every day and see what happens.
Been using for ages great product
I have more energy and can don't have the usual mid afternoon tiredness.
Sceptical after being let down by numerous supplements to help menopause. Week 2 thought'Here we go again, no change.' Wrong. Started taking 2 per day, end of week 4 and feeling fab. More energy, better sleep and am actually enjoying walking. Its not an instant effect. It creeps up on you and you find you 'feel great' a bit more often over a few weeks so stick with it. Thank you VivaNMN, my new best friend.
Noticed my hair is thicker
Awesome
Roughly 5/6 weeks in and I can see a difference in my energy levels I'm more focused and don't seem to crash anymore also sleeping a lot better will carry on taking infact just purchased 3 x 90 bottles so definitely in for the long haul 😀 👍 👌
I have been using Viva now, for almost a year! As a 52 year old menopausal women, I have noticed significant change in my energy, mood and even my skin. They arrive on my doorstep each month, this is one supplement to which I shall not be unsubscribing too *****
Excellent everything
Pleased with purchase. Will continue taking this as part of my routine! Feel more active which is good!
I will be starting month 3 of taking the NMN and I can say without a doubt it has massively improved my energy levels. I have a clean flow of energy all day, dont have the 2pm crash. Pairing it with functional mushrooms have my peri menopause symptoms ease. Love this and has changed my life for the better
I need purchase more Can you help me please
I’ve been on NMN for about 4 months and I’m just beginning to feel the effects. I’ve been suffering with arthritis for a number of years and now have to rely on mobility scooters and wheelchair to move around. I was due to have a total knee replacement, but since taking NMN, I feel I have more mobility and less pain . I wake in the morning and although it takes a few minutes, I can now get to the loo without a walking stick. I have now cancelled my knee op. Plus, my nails, skin and hair all have improved with growth and texture. I plan on taking NMN for many years to come. The benefits speak for themselves.
Great product
I have not been using it long enough to tell yet. As far as customer service goes they are great .
