What does NAD+ do for the body?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme every cell uses to produce energy and support DNA repair and cellular maintenance. NAD+ levels tend to decline with age, which is why it is used in physician-supervised longevity and wellness programs. NAD+ therapies are not FDA-approved to treat, cure, or prevent any disease.

Its role in the cell

NAD+ is central to how cells convert nutrients into usable energy and supports enzymes involved in DNA repair and cellular signaling. Because it is fundamental to metabolism, interest in maintaining NAD+ levels has grown in longevity medicine.

How it is used

In physician-supervised programs, NAD+ is used to support energy, recovery, and general wellness goals. It is not FDA-approved for these uses, and appropriate candidacy and dosing are determined by a physician.
