Improved sleep quality, better health.

Posted by Emma on Oct 09, 2017 | Verified Purchase

I was very sceptical when I bought this, despite all the scientific evidence. The first thing I noticed is how quickly I fall asleep and how much more rested I am when I wake up. It works better than melatonin 5 mg. I am also less stressed, less tired and have virtually no cravings for junk food. I don’t know whether it is because of this supplement or a side-effect of improved sleep quality. I take 2 pills (500 mg) once a day, in the morning, about 30 min before breakfast.

Seems to be working...

Posted by MikeMember on Sep 28, 2017 | Verified Purchase

I take several anti-aging supplements, so it's difficult to be sure which ones are working. That being said, I have noticed that my hair (at 64) has started getting darker again since taking this product. It is expensive, but I'm on my second bottle now. In addition to my hair color, I also feel a bit more stamina these days.

Immediate change

Posted by iHerb Customer on Sep 25, 2017 | Verified Purchase

I felt an immediate change after three days already, I guess it does not affect everyone in the same way but I can say that with me it affected my anxiety level and I felt a definite reduction with compulsive thoughts to the level of zero I switched it gradually with the chemical prescription drug I received, I guess I really had significant deficiencies of this component, I did not expect it to be so helpful

An Investment In My Health - Well Worth It!

Nicotinamide riboside. I like it.

Posted by iHerb Customer on Aug 30, 2017 | Verified Purchase

Works for me. First time I took it I felt the increased energy straight away. Like many supplements the effects fade a bit over time. So I tried doing without it but the tiredness crept back , so I'm back on it. One really noticeable effect for me is how much better I sleep when on it. Wake up earlier and clear headed. Beneficial for me , as I was never a morning person.
