The science, simply

The quiet decline behind feeling older

NAD+ is a molecule in every cell of your body, essential to the chemistry that keeps you energized. It is not something most women have heard of — until they learn what happens to it with age.

NAD+ levels fall as we age. By midlife, research suggests cellular NAD+ can drop to roughly half of youthful levels — part of why your 40s and 50s can simply feel different.

Based on published aging research on NAD+ decline.
