Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in every living cell. It’s essential to every cell but especially to those with mitochondria. That’s because the mitochondria are “the powerhouse of the cell.” Meaning that like any other battery or energy resource, the mitochondria depend on an external power source to keep them charged. NAD is that source. With healthy NAD levels, our cells can function at their best and so we can too.


We use NAD every day for basic functions like sleeping, breathing, eating, and drinking. NAD plays a critical role in a wide range of cellular reactions. Scientists have known about the vital role of NAD since 1906. Since then, they’ve learned NAD is found in every living cell, and that it powers the mitochondria, which keeps almost every tissue in the body healthy.
