Trying NR for NAD+ boost – any noticeable changes in energy or sleep?

Hey folks, I’ve just started taking NR (nicotinamide riboside) at around 300 mg most mornings, mostly because I read it’s a precursor to NAD+ and thought it might be worth a punt for general energy support. I’m not claiming any miracle effects, just sharing what I’ve noticed so far. For me, after about two weeks I felt a slight bump in daytime alertness, especially during those mid‑afternoon slumps when I usually reach for a coffee.

It’s subtle though – could just be placebo or the fact I’ve been sleeping a bit better lately. My sleep tracking shows a few more minutes of deep sleep, but again, nothing dramatic. I haven’t seen any changes in skin or recovery from workouts that I can pinpoint to the supplement.

I’m keeping an eye on any GI upset – so far so good, just the occasional mild nausea if I take it on an empty stomach. I’d love to hear if anyone else has tried NR and noticed anything concrete in energy, mood, or biomarkers. As always, chat with a doc before tweaking anything, especially if you’re on other meds.

  • vo2max_sleep: I had a similar experience when I tried NR a few months ago. I was doing 300 mg as well, mostly to see if it helped my recovery during heavy training blocks. For me, the energy bump was very similar to what you described. It was not like a caffeine rush, but more like my brain felt less foggy during the afternoon. I also noticed some mild nausea if I forgot to eat breakfast first, so maybe try taking it with a small snack. I did not see much change in my sleep, but I was curious about the long
  • weekendemma: Fair play for the tip about the snack, I will try that because the nausea is a bit gas. It is a relief that the afternoon brain fog thing is not just me being delusional? I have not thought about blood markers yet. Is there even a reliable way to test NAD+ levels that does not cost a fortune?
