An unexpected side effect !

First of all, the Customer Service from this company is excellent. They were quick to respond and very helpful when I sent an enquiry.
The tablets themselves have absolutely changed my life, and that's no exagerration on my part. All the signs of aging were creeping up on me, one bit at a time until I realised I was slow, tired, foggy-brained, inactive and generally on the downward slope to old age. Since taking VivaNMN I have come back to life - literally. All my friends are saying I look younger - I have more energy, my brain is sharper, and (dare I say this in public?) my libido is back with a vengeance! Wow! An unexpected side effect! I've recommended VivaNMN to all my friends.

Easy and convenient ordering with quick efficient delivery - the nmn product has definitely made differences in my (F58) and my husband's (M60) lives - improved energy, better sleep and even though I am menopausal and have PCOS my hair has absolutely stopped falling out - there's been an improvement of skin condition and muscle tone - i would definitely recommend this product

The real deal!

I originally started taking VIVANMN for a period of 3 months and was not sure they were working for me, although I was sleeping more deeply. I took a break for a couple of months mainly for financial reasons and then I really noticed the difference. I was so tired and lethargic all the time. So now I have taken out a monthly subscription. These really do work, I have so much more energy. I also like the fact they are tested by a third party. Give them a try, you won't regret it.

Unbelievable

For the first four weeks I didn’t notice any difference after taking NMN, the second four weeks I felt I had a little more energy but not obvious. After the third four week period there was an obvious difference in my energy clarity of mind and an unusual difference I noticed, this difference was in my left knee. I know NMN is not for this, but I have a meniscus tear and arthritis in this knee which I’ve had confirmed through scans. The knee had gradually got worse over an 18 month period but three months after taking NMN I noticed my knee appeared to be more pain-free. I have done nothing different in my lifestyle or nutrition during the past three months, the only thing which I am doing different is taken NMN and I feel that this is the reason why my knee is feeling more stable, more pain-free and stronger. I am still aware of my knee issue, but I can honestly say that The symptoms of the meniscus tear and arthritis have virtually disappeared.
