My wife and I were debating the use of supplements yesterday.  We got on to NAD+ and 🤔:

People with high X (cell health) have high Y (NAD+).

If we measure Y to determine X, does supplementing Y raise X (cell health) or does it just increase Y (the thing we measure -> NAD+). 

Does anyone know?

all i can say is that personally when ive been using NAD+ (Tru Niagen brand) I have even higher performance and energy levels than my baseline

Ran out last week and ordered a six month supply when it was on sale the other day

Worth to keep it in the stack
