NAD+ has become one of the most talked-about molecules in wellness, but most of the buzz skips the basics. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, and your body cannot make energy or repair itself without it. The catch is that NAD+ levels fall as you age. Here is what NAD+ actually is, what it does, and why people are working to restore it.
What is NAD+?
NAD+ is a coenzyme your cells use to turn the food you eat into usable energy. It shuttles electrons inside your mitochondria (the power plants of your cells) and switches on the enzymes that repair DNA and regulate aging. Without enough NAD+, that whole system slows down. It is made in the body from vitamin B3 (niacin), so it is related to B3, but it is not the same thing: NAD+ is the active molecule your cells actually run on.
What NAD+ does for your body
- Energy and metabolism. NAD+ is central to how your cells convert food into ATP, the energy your body runs on.
- Cellular repair. It powers the enzymes that repair DNA and clean up cellular damage.
- Healthy aging. NAD+ activates sirtuins, proteins tied to longevity and cellular resilience.
- Brain and focus. Neurons are energy-hungry, and NAD+ supports mental clarity and steady focus.
- Recovery. Better cellular energy and repair can support faster recovery and less fatigue.
Why NAD+ declines with age
NAD+ levels drop steadily as you get older, and stress, poor sleep, and inflammation can push them lower still. Many researchers believe this decline is one reason energy, recovery, and cellular resilience fade over time. That is why restoring NAD+ has become a focus of longevity and optimization medicine.
How to raise your NAD+
You can support NAD+ with the basics (quality sleep, exercise, and a nutrient-dense diet), and with precursors like NAD+ boosting supplements. For a more direct effect, NAD+ can be delivered by IV or injection so it reaches your bloodstream at higher levels than a pill. At Recovery Project, NAD+ therapy is physician-guided and tailored to your goals. Learn more about our NAD+ therapy and the benefits of NAD+ IV therapy.
Is NAD+ safe?
NAD+ therapy is generally well tolerated when done under medical supervision. Some people feel mild, temporary effects during an infusion, such as flushing or a sense of pressure, which ease when the drip is slowed. The important part is that a provider evaluates whether it is right for you and monitors your response, rather than guessing on your own.
Frequently asked questions
NAD+ helps your cells turn food into energy, powers DNA repair, and activates enzymes tied to healthy aging. Because it touches so many systems, low NAD+ can show up as low energy, slower recovery, and reduced resilience.
No. Your body makes NAD+ from vitamin B3 (niacin), but NAD+ is the active coenzyme your cells actually use. Think of B3 as a raw material and NAD+ as the finished, working molecule.
NAD+ is generally well tolerated. The main side effects are mild, temporary infusion sensations like flushing or chest pressure, which improve when the drip is slowed, and Recovery Project's medical team monitors your response throughout.
It depends on your goals and your labs. At Recovery Project, your provider builds a personalized schedule and adjusts it based on how you respond, rather than a one-size-fits-all plan, whether you're in Magnolia or connecting by telehealth across Texas.
