4/5

Works very well !

I take Vitamin D + K2 at the same time with Magnesium and feel more energy and vitality

Good product. Well packaged. The provider responds promptly.

I initially purchased and now take this product daily because, among the other forms, it includes Magnesium L-Threonate which has been shown to improve cognition, especially in older adults.

I was pleasantly surprised to find the price point, which I think is affordable compared to many others. As far as I understand, Uthever's NMN is high-quality stuff. The order was delivered very quickly.

I am really satisfied and will continue to order.

Habe in den letzten Jahren nacheinander von 5 verschiedenen Lieferanten gekauft. Da ich die Kapseln meistens öffne, um das Pulver in fettreiche Joghurt zu mischen, habe ich zuletzt mit einem "Testsieger"Produkt zunächst gute Erfahrungen gemacht, doch bei späteren Lieferungen kam plötzlich ein abstoßender Geschmack zu Tage. Nachfragen blieben ohne Antwort. Bei Source of Nature kommt zum guten Geschmack ein guter Preis und schnelle Antwort bei Fragen.

I never receved the order

This is one of the few "longevity"-hyped products that actually makes a difference because it replenishes the energy-reserves in all cells. Everything just starts working better after taking this. Sleep, cognition, physical performance (and even sexual lol).
What I like the most is the mental clarity that settles after a few weeks at 1g.

NMN is SO expensive and there are a lot of fake or diluted products out there so I am happy that Source of Nature delivers the best and most revered (Uthever) NMN at the lowest price I have seen, at least of an authentic product. After I started taking NMN a year ago I have never felt better in my 42 year long life so the price is worth it to me. Try for yourself.

First I thought that the price was a little low at least compared to the competition but after I have received the product there is no doubt that this is Uthever NMN. Apparently it is their new generation that should be chemically stable at room temperature but I will have to check for myself.
The pouch is very professionally packaged. One thermally sealed (and resealable) outer pouch with moisture absorber inside and an inner zip-lock pouch with the powder. As a bonus it also contains a scoop which holds ca 500mg.

I have tried to many different brands of NMN and half of them if not more are fake! This one is the real deal, it has the right taste, texture and after a couple of days I already feel the changes starting to happen. Clear mind, more energy throughout the day and actually feel less hungry.
5/5 stars from me

I love that this brand are so transparent. I asked them for documentation and certificates as well as other questions and they answered all of my questions right away. Top notch product they sell here (y)

Zinc is such an underappreciated mineral and this product seems of very high quality

This is a really good product!
Most zinc products use a zinc with very low bioavailability but this is a combination of the two types with absolute highest bioavailability.
Really appreciate what this company is doing with their supplements, you can tell that they put a lot of effort into the formulations and it works!
I take this together with their Magnesium 6-in-1 supplement to boost performance levels and get better sleep and more energy.
5/5
