What Is NAD?
Nicotinamide adenine dinucleotide (or NAD) is one of the most crucial molecules for any living organism because it is a key player in multiple metabolic reactions within a cell’s mitochondria. Without it, energy collapses and DNA integrity diminishes very quickly.
The short answer is: you need NAD to function on a daily basis.
The problem is that many people are deficient in NAD which makes it extra difficult for cells to generate enough energy to do their job well, if at all. Cells that can no longer do their jobs means that metabolic functions throughout your whole body are affected (metabolic disorders), age-related illnesses set in (neurodegenerative diseases), and DNA is more likely to be damaged (premature aging). It also makes it challenging to regulate sleep/wake cycles (your circadian rhythm).
Deficiency of NAD is never a good thing for ANY body.
