If I Supplement My NAD, Will My Body Stop Producing Its Own?

No, your body knows how to produce NAD and won't stop doing it. However, as you get older, your body will either need more or produce less....

Human studies show that after supplementation ends, NAD levels drop to what they were before -- they are not further depressed.

Our bodies do not become increasingly dependent on any other vitamin when we supplement, and there is no reason to think it is true with NAD precursors. It is true that NAD levels drop over time, but that is not caused by supplementation, and indeed occurs regardless of whether you supplement.
