The Basics
What Is NAD+ and Why Does It Matter?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It sits at the center of how your body turns food into usable energy and how cells repair and maintain themselves. Without adequate NAD+, the mitochondria that power your cells cannot work as efficiently.
Here is the catch: NAD+ levels naturally decline with age, and by midlife many people carry far less than they did in their twenties. That decline has made NAD+ one of the most discussed molecules in longevity and health-optimization medicine.
At Protocol Health in Scarsdale, NY, we approach NAD+ the way we approach everything: as a physician-supervised, individualized therapy informed by your goals and, where appropriate, your labs.

What Does NAD+ Therapy Do, in Plain Terms?
NAD+ therapy aims to replenish a coenzyme your body depends on for energy production, DNA repair, and cellular resilience. By supporting these fundamental processes, it may help some people who experience fatigue, brain fog, and the cumulative wear of aging.
It is delivered most commonly as an IV infusion, and sometimes by injection, under clinical supervision. Research suggests NAD+ can support metabolic and cognitive function, though responses vary from person to person and it is not a cure for any specific disease.
Think of it as maintenance for your cellular machinery rather than a quick fix. The goal is to support how your body already works, not to override it.
The Mechanism
How Does NAD+ Work in the Body?
NAD+ has two main jobs. First, it acts as a shuttle in metabolism, carrying electrons through the reactions that convert food into ATP, your cells' energy currency. When NAD+ is abundant, that energy pipeline tends to run more smoothly.
Second, NAD+ is a required fuel for a family of repair and regulatory enzymes called sirtuins and PARPs. These proteins help maintain DNA, regulate inflammation, and manage how cells respond to stress. As NAD+ falls with age, these protective systems can lose efficiency.
Delivering NAD+ intravenously bypasses digestion and makes the coenzyme directly available to tissues. This is why many clinics, including ours, favor IV or injectable delivery for people seeking a more noticeable effect than oral precursors alone typically provide.
The Upside
What Are the Potential Benefits of NAD+?
The most commonly reported benefits are improvements in energy, mental clarity, and a general sense of vitality. Many people pursue NAD+ specifically for fatigue, brain fog, or the feeling of running on empty despite adequate sleep.
In the longevity and recovery context, NAD+ is studied for its role in mitochondrial function, cellular repair, and metabolic health. Some people use it as part of athletic recovery or after periods of high stress, illness, or intense training.
It is important to be honest here: individual responses vary, and NAD+ is not a guaranteed outcome for anyone. We frame it as one supportive tool within a broader, lab-informed longevity plan rather than a standalone solution.
Is It For You?
Who Is a Good Candidate for NAD+ Therapy?
NAD+ tends to appeal to adults dealing with persistent fatigue, brain fog, and low energy, as well as those pursuing proactive longevity and preventive health. It is often considered alongside broader work like hormone optimization or metabolic health.
Candidacy is determined during a consultation. A provider will review your history, goals, medications, and relevant labs to decide whether NAD+ is appropriate and, if so, at what dose and cadence. Certain conditions and pregnancy warrant caution or may make it unsuitable.
If you are exploring NAD+ as part of a bigger picture, a comprehensive evaluation such as one of our longevity assessments can help clarify where it fits. The right starting point is a conversation with a clinician who can tailor the plan to you.
The Fine Print
Is NAD+ Safe, and What Are the Side Effects?
When administered under clinical supervision, NAD+ is generally well tolerated. The most common experiences occur during the infusion itself: a flushing sensation, chest tightness, nausea, or lightheadedness if the drip runs too quickly.
These sensations are typically managed by slowing the infusion rate, which is one reason clinical supervision matters. It is also why we do not recommend unmonitored or at-home high-dose protocols.
NAD+ can interact with certain medications and conditions, so a thorough intake is essential. As always, this content is educational and is not a substitute for personalized medical advice from a qualified provider who knows your history.
The Experience
What Should I Expect at a NAD+ Appointment?
Your first step is a consultation to confirm NAD+ is appropriate and to set a dose and schedule. Some people begin with a series of sessions to build up levels, then move to periodic maintenance.
An IV infusion is administered slowly and can take from roughly 45 minutes to a few hours depending on the dose. You will be seated comfortably, monitored, and the rate adjusted to keep you at ease throughout.
Many people describe feeling clearer or more energized in the days following a session, though timing and degree differ. Your provider will help you gauge your response and adjust the plan over time.
The Protocol Health Way
How Does Protocol Health Approach NAD+?
We are a family-owned, physician-led clinic in Scarsdale serving Westchester and the greater NY, NJ, CT, FL, and CA area, with telehealth options for hormone and longevity care. Every NAD+ plan is overseen by our clinical team and built around you.
Rather than treating NAD+ as a menu item, we position it within a lab-informed longevity strategy. That may mean pairing it with body composition, biological age, or hormone assessments so decisions are grounded in data, not guesswork.
If you are curious whether NAD+ belongs in your plan, the best next step is a personalized consultation. Our team will help you understand the options and design an approach that fits your goals and your physiology.
FAQ
Frequently Asked Questions
Is NAD+ a peptide or a vitamin?
NAD+ is neither, strictly speaking. It is a coenzyme derived from vitamin B3 (niacin) that every cell uses for energy metabolism and repair. It is often grouped with peptide and longevity therapies because of its role in cellular health and aging research.
How long does NAD+ therapy take to work?
Responses vary widely. Some people notice improved energy or clarity within a few days of a session, while others build benefit over a series of infusions. Your provider can help set realistic expectations based on your goals and health profile.
What is the difference between NAD+ IV and NAD+ injections?
IV infusions deliver a larger dose slowly into the bloodstream and are common for initial protocols. Injections offer a lower-dose, more convenient option that some people use for maintenance. A clinician will recommend the right route for your situation.
Can I get NAD+ therapy through telehealth?
IV infusions are performed in-clinic for safety and monitoring. However, an initial consultation and parts of your broader longevity plan can often begin via telehealth across the tri-state area, with in-person visits scheduled for infusions.
Does NAD+ reverse aging?
No responsible clinician will promise that. NAD+ supports processes tied to cellular energy and repair that decline with age, and research is ongoing. It is best understood as a tool that may support healthy aging, not a cure or a guarantee against aging.
How often should I get NAD+ infusions?
There is no universal schedule. Many people start with a short initial series and then move to periodic maintenance sessions. Frequency is individualized during your consultation based on your response, goals, and labs.
