Trying a low‑dose NMN + NAD+ combo – any tips on timing and sleep?

Posted by shay_hrv in Longevity & Anti-Aging - 1 points, 4 comments.

Hey folks, ngl I’m pretty new to the whole NAD+ thing and just started a modest stack after reading a bit about NMN and direct NAD+ infusions. I’ve been taking 250 mg of NMN every morning with breakfast and a 300 mg oral NAD+ supplement (the sub‑lingual powder) around noon.

For the first week I felt a mild boost in mental clarity around mid‑day, but by the evening I started getting a bit of jittery and my sleep was off – I’d lie awake for an hour or two. I’ve read that taking NAD+ late can cause insomnia, so I’m wondering if my timing is the issue or if the dose is too high for me.

I’m also curious if anyone has noticed any GI upset or flushing with these low doses, and whether it’s common to cycle or just keep it daily. I’m not looking to replace any meds, just experimenting safely while I keep an eye on my blood work. Any practical advice on when to take NMN vs NAD+ or if I should taper the midday dose would be appreciated. Thanks!

  • theo_benchpr: I was in a similar spot a few months back. I kept NMN at 250 mg in the AM, but moved the NAD+ powder to the early afternoon (around 1 pm) and cut it to 150 mg. The jittery evenings cleared up for me, probably because the NAD+ boost was winding down before my natural melatonin rise. I didn’t notice any flushing or stomach upset at those levels. I also try a light “off” day once a week just to see how my baseline feels. How close are you to your workout window? Timing it around post‑gym can somet
  • renee_d: That makes sense, I’ll try moving the NAD+ down to early afternoon and dropping it to about 150 mg and see if the evening jitter fades. I usually hit the gym around 6 pm, so a post‑workout dose could be worth testing too. Thanks for the tip.
  • shay_hrv: wait, i think you might have mixed us up? you're replying to me but you're talking like you're the one taking the stuff. ngl i'm the one who's new here and struggling with the insomnia. i'm still at 300mg for the sublingual stuff. do you actually think moving the dose to early afternoon helps with the jitters, or is it more about the total amount? i'm still trying to figure out if 250mg of NMN is too much for my system.
  • shay_hrv: Thanks for the rundown, theo_benchpr. I’m actually hitting the gym around 6‑7 pm, so moving NAD+ to early afternoon could help avoid that crash. I’ll try dropping it to 150 mg at 1 pm and see if the night jitter eases. I’ve been doing daily so far – I’ll experiment with a “off” day on Sundays like you mentioned and compare baseline vibes. I’ll keep you posted!
