I initially thought it would, but I still sleep fine.
Not very long. Hitting the 3-4 week mark now? I try to do 600mg glutathione 2x a week as well. I've definitely hit a point of diminishing returns with going over 1g NAD+/day. But compared to the oral NAD precurors I was taking before this, the difference is (feelz-wise/cosmetically) night and day.
Like a week into the high dosage NAD+, I had a layer of dry skin all over my body. Was thinking wtf why's this shit so unusually dry? Scrubbed it off and had clearer better skin. In terms of hair, barber gets confused about why it gets better every time in terms of color and volume. Don't know what the fuck that means exactly, but if a hair pro that doesn't generally make those comments does...I'll take it lol. Granted, those comments were also made while I was initially supplementing with liposomal NMN, the skin thing at least was never that prominent.
Ladies and gentlemen, thank you for reading this unscientific feelz report on NAD+. I understand that the science may say this or that, but I don't exactly like to live my life as if it was an exact science experiment. Rocky sees something interesting, Rocky tries. Rocky gets benefits that he otherwise wouldn't get? Rocky continues.
