Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme found in every living cell and is essential for healthy mitochondrial function. That is because the mitochondria are “the powerhouse of the cell.” Meaning that like any other battery or energy resource, mitochondria depend on a source of energy support to help 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 the early 1900s. Since then, they’ve learned NAD+ is found in every living cell, and that it powers the mitochondria, which keeps almost every cell and tissue in the body alive and healthy.
