Purchased direct from site after good reviews about quality of product. Extra bottle at reduced cost. Been taking for just a month and half. Physically not any significant change but feel more sharp mentally. Email reminders appear genuine although may be marketing strategy. The money back offer if no results are found gives faith in that they believe in their product. Will review after 3 months

I take one every morning as a 'treat to my skin' gift to myself! I'm hoping its working away inside on my face skin - I've already seen a reduction in horizontal lines on my neck and a tightening of neck skin

Ian O. 5/5 Verified
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.

Will leave more detailed review after taking the capsules long term , only 1 month in but things seem positive my afternoon slump seems to have gone , & my sleeping of an evening seems to have improved. But still early days will keep up taking the capsules daily & long term, & see if results improve further. Consistency & longevity will be key to see further results!

After trying Black forest NMM in USA I decided to give Vivanmn a try -they are ranked top 5 in 2026. Not tried capsules yet but Viva have provided good communications and support as i Missed first and second deliveries while away and they offered a replacement at no extra cost which I received today. Not many companies offer this help.
Roy L. 5/5 Verified
I have been taking Viva NMN for about a year now and have definitely noticed the difference. However I seem to have plateued a bit so I’m going to try a brand that has resveratrol to see if I notice any difference. If not I will be back and just up my dosage. M 47
