My subscription arrives on time (30 tablets per pot and some months have 31 days!)
Happy with product; you get a lot of emails asking for feedback which I don't usually get around to. I'm loving the app and hopefully will get similar discounts as a regular loyal user compared to first time buyers
The product is amazing
The product is amazing. Having trusted the reviews, I decided to try NMN. I done a good deep dive into the resons I would need it. It does make a difference, unsure why, whether a chemical rebalance or a top up of required hormones, it makes me feel better.
It's worth the little sacrifice and a little mindset change.

Since taking Vivanmn I have regained my strength. It has helped me through a bad time healthwise. I take it first thing every morning and will continue to do so. I never forget to take it as I know it’s doing me good
Is it a miracle?
The delivery is on time as I have requested an update to my order. All was well and not a problem at all.
Taking the product for nearly 3 months, I am feeling much better and full of life, also I have been told I look about 40 when I am nearly 68, .

Great product and company
This is a fantastic company and a great product. I feel so much better for it, aching joints gone and the amazing benefit that my grey hairs have massively reduced! My husband joined me and has noticed the reduced grey also. I love the new app that subscribers get included and the discounts I get for logging in.
This is a scam -Update
Update the team at Vivian contacted me regarding my review, I sent them the details of my order and the confirmed that this was not an order that had gone through them but a copy at site, they’ve resolved my issue and sent me a trial if the real products which was totally unexpected and I’m incredibly grateful to them for this as I was really looking forward to trying the product after reading all the positive reviews!
Can’t fault their customer service or how quick they respond to feedback!
Thank you vivanmn

Uk made NMNS that delivery results
"I started taking these tablets three weeks ago already have so much more energy. I'm going to be 69 next month. I'm back in the gym now not falling asleep halfway through the day but enjoying it. Go ahead and try them and see the difference for yourself."

I am coming into my third month of taking NMN and I will say it has made a difference to my energy levels. I will continue taking them as I feel it is making a difference.

The 2 star review is given for the product and its effect (or lack of) for me. Initially I ordered one month trial, was then contacted just before the month end offering a discount if I ordered some more. I wrote back advising that I had been taking them daily and hadn’t noticed any changes at all to my energy, focus or well being. They advised that I should try taking 2 capsules a day and would offer me a bigger discount - as I was hopeful for change I bought into it. After this 2nd month I have still not experienced any changes or improvements. I mistakenly thought that the 100 day money back guarantee was for if the product wasn’t suitable or didn’t work for you. There is a 100 day money back guarantee but you have to return the items as new (sealed & unused). However I must say that their customer service support has always been very prompt, professional and friendly.
Great product
Great product, helpful customer service and swift delivery. Give it a go!
100% + Customer Service
The best customer service. They listen to you, respond quickly, efficiently and in a friendly manner. They explain everything. I cannot remember the exact date of our emails but probably between September 10th to 13th. Best customer ever.
old age has a helper
I have more energy and don't hit the 3 o'clock slump. I'm very pleased with the results
Vivanmn
My friend recommended this to me but I was very skeptical about any kind of supplements but these actually seem to work!
Have more energy and feel better in my all round general wellbeing.
The service from Vivanmn is spot on as well, I am subscribed for life!

"Excellent service from start
"Excellent service from start to finish. Postage and packaging are great — delivery is within two days via Royal Mail, straight to your property, never had a problem.
I've been taking the product for four to five months now and the results speak for themselves: my skin elasticity is noticeably better and the bags under my eyes have gone. My energy levels have improved too — I'm up every day at 4:30am for a six mile bike ride. I do still flag a little around 3pm, but that might just be down to getting older! 55 years old, feeling 29
Really impressed with the products, the website, and the app that's just launched. Can't recommend them highly enough."
