Hi Forever21! I'm not sure what others would recommend on the board here, but if I were you I would go with the recommended dose for a little while at least (perhaps a month or more). Some people are more sensitive than others and I've heard reports of people getting a tad too much energy out of it to begin with which sort of turns them off to it. If you find that 250mg is too much, just take 1 pill per day instead (125mg). As you get comfortable with it you can try experimenting with some higher dosages. Note that Dr. Brenner now takes 500mg if I'm not mistaken. Keep in mind he's been taking it for quite some time now. I've been taking it for a long time and have experimented with extremely high doses with no ill effects but I believe my body is somewhat less sensitive than others. Everyone's body will be somewhat different despite the fact that all of us have NAD metabolism in every cell. I would also recommend taking it in the morning. I know that when I first began ramping up my dosage, I began by taking another 250mg at dusk. That kept me awake and I had difficulty falling asleep. This no longer happens to me, I sleep like a baby but it was quite irritating initially. I couldn't take it any later than 3pm or 4pm (I typically go to bed around 10pm +/- 1 hr). I didn't notice any differences with regard to taking it with or without food, so I'll leave that to others to discuss if they've noticed anything. You might be able to find some information on that by pouring through the personal experiences thread on NR, but it is quite long.
Anyone notice any difference taking it with/without food?
Also keep in mind, you are fairly young so you may not notice anything consciously even if it is helping you by repletion of NAD within your cells.
And if you are inclined or bored out of your mind I would also recommend doing searches on google scholar for anything related to NAD, NR, NMN, NRK1 & NRK2, NMNAT1 & NMNAT2, NAMPT, sirtuins (SIRT1-7 in humans and SIR2 in yeast), PARP (1-16), cADPR, ATP, ADP, CD38, CD157, ENTs, CD73, CLOCK, BMAL1, FOXO1, PGC-1α, mTORC1, CaMKK, AMPK, am I forgetting anything? It's a rabbit hole! This is always a nice collection of articles to refer to: http://aboutnad.com/...research-on-nr/ although there is much more out there beyond this!
