NAD vs NMN

NAD and NMN are often mentioned in the same breath, but they play different roles in cellular energy and aging.

What Is NAD?

NAD is a coenzyme essential for mitochondrial energy production. Without enough NAD, ATP output drops significantly.

What Is NMN?

NMN is a precursor to NAD. It helps the body restore NAD levels, especially as we age.

NAD vs NMN: Key Differences

• NAD works directly in the mitochondria
• NMN helps increase NAD availability
• Both impact longevity and energy metabolism
