What Is NAD+ and How Does It Work?

NAD+ has become a popular topic in longevity and wellness circles, but what actually is it — and what role does it play in the body?

NAD+: a coenzyme essential to every cell

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell in the body. It plays a central role in cellular energy metabolism, helping convert nutrients into the energy cells need to function. It’s also involved in supporting cellular repair processes.

Why NAD+ levels are a topic of interest

Research has explored how NAD+ availability in the body may relate to cellular energy and function over time, which is part of why it has become a focus of longevity-oriented wellness routines. It’s important to note that NAD+ therapy is a wellness offering — it is not a treatment for any specific disease and has not been evaluated by the FDA for that purpose.

How NAD+ is typically administered

As part of a longevity program, NAD+ is generally administered as an injectable or IV therapy in-session, under the guidance of a care team. Frequency and approach depend on individual goals and provider recommendations. Many people pair NAD+ with glutathione, another antioxidant-focused longevity therapy.

What to know before starting

Like any wellness therapy, it’s worth discussing your full health picture — including other medications or supplements — with your care team before starting. Mild redness, swelling, or discomfort at the injection site is the most commonly reported effect, and some people report mild flushing, fatigue, or headache shortly after a session.
