If NR is having no effect on you...
 
Certain bottles of NR seem to have far more positive effects on me than other bottles of the same brand.  And that's an understatement.  I am not talking about just slight differences, but a "night and day" difference in the effect: no detectable effect vs tremendous positive effect.  And the dosage is not what makes the difference. One capsule from one bottle has more profound effects than 10 capsules from another bottle.
 
I had suspected this before, but for a second time I've opened a bottle and just one capsule has had remarkable positive effects on me -- I'm sharper, my appearance is improved, my energy is higher --- whereas I've been taking 3-5 capsules/day from other bottles and the main thing I notice is being more sleepy by evening!  
 
So far I estimate I've consumed about 20 bottles.  The second bottle had amazing effects on me, whereas the first bottle did nothing.  Bottle #2 is why I continued taking NR.  Bottle #2 is why I continued taking NR in spite of the foot pain that began when I was on bottle #2.   Bottle #20 is effecting me the way bottle #2 effected me: truly amazing results. Like holy sh*t results.   When I switched to the more expensive brand for 2 bottles, the effects were also very positive, but not at the level of bottle #2 and bottle #20.  And for the other bottles of my usual brand, I'm not saying all the other bottles except #2 and #20 were duds. Rather I think there is spectrum wherein some bottles were more effective than others -- and the last several were not so great.  However, bottle #2 and #20 stand out as being superior to all the others.  
 
I had long wondered why only bottle #2 had incredibly profound effects on me.  I assumed the answer must be that I had become accustomed to NR.  But I could never account for why bottle #1 had done nothing for me.  Now that I'm up to 500mg/day I generally don't feel much from it.  This week I open bottle #20 and I take just 125 mg and WOW.  So I'm back to thinking the bottles really are different.
