I started NAD (today is the 3rd day) and I'm surprised to find that so far I have noticed a significant positive effect. I feel like I have more energy, but since it's early days I'm not deliberately changing my activity level. Want to make sure the effect lasts before I go messing with an energy envelope that works.
More surprisingly, my HR is noticeably changed. My HR upon waking has dropped steadily from 88 bpm to 78 bpm.
At the same time, my HR supine after being up and about for 5-10 mins has locked in at 104 bpm where previously it varied on a daily basis between 100 bpm and 116 bpm.
This could be a data blip, or it may be related to NAD but not lasting, or it may be the effect of Equilibrant (I started that 6 weeks ago at a low dose). Thought it was interesting enough to share, though.
