I took these the last 3 nights in a row. I’m normally a brilliant sleeper and I’ve had 3 terrible sleeps and I’m thinking what is going on here! Then I realised the only thing I changed is taking these Nmn the last 3 nights. So I put it in ChatGPT when am I supposed to take these and it tells me of a morning because it gives you cellular energy. It was a great energy I had, didn’t feel sick, was feeling motivated but when I was supposed to be sleeping lol! This has left me feeling great as what a fantastic supplement it must be it starting working the same night! To add, I still feel great in the day even though I had not much sleep. Super excited to try in the day now. I can feel a real positive difference in my get up and go. If I could give it a 10 star I would!!
