Somebody told me they were taking NAD+. I was surprised you could even by NAD+. I thought everybody took NAD precursors (NA, NR) but I see Amazon sells NAD+ amazon.com/Liposomal-Supple...
All the medical papers I see say to boost NAD+ to take precursors. I take Nicotinic Acid.
The Amazon product says you are skipping the precursor and adding the NAD+ directly. I wonder if it survives digestion?
