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?

Also supplementation doesn’t take into account things like bioavailability of something, the form it’s being consumed in, as we are finding out when adding a mineral to a food doesn’t necessarily mean you will absorb it the same way if you were consuming a food rich in the mineral

This was a huge part of our convo. 

It’s the biology version of “a great product with poor distribution is a failed product”.
