                                Cellular NAD+ levels naturally decline with age, which is a major reason many people turn to supplements. If you suddenly stop taking NAD+ precursors, such as NMN or NR, your body's NAD+ levels will gradually return to their previous baseline. This transition can lead to a perceived "crash" as the supplement's effects on energy and cognitive function fade.
