How Your Body Makes and Loses NAD

The role of NAD in the cell is incredibly complex. It's not just a simple case of adding two things together makes more NAD, and that's the end of it. There are five different what we would call precursors that NAD can be made out of. And once these are inside the cell, they end up various different pathways, which then assemble them into NAD. The most important pathway for NAD production is something called the NAD salvage pathway.
