This is something I will try, in short cycles. It is expensive and is not sustainable for long term use.
My wish is that quality supplements will be sustainably priced so they are available to everyone.
The first two weeks of taking this had me very excited about the energy boost I was experiencing. No more afternoon slump. No more feeling anxious/overwhelmed by the usual stressors. But I've noticed this tapering off as I head into my third week taking it. I'm going to continue, though...
Overall, I feel better. A bit more energy, but really just seem to be able to switch tasks easier. Felt hot and flushed half the days first thing after taking, but that went away quickly.
I honestly don't feel any difference in my health since I started taking NAD. It makes me regretful that I purchased 3 bottles. I'll give you it a little longer and see if it changes anything.
