What Is NAD+ Therapy?

If you have been paying attention to the wellness world over the past few years, you have likely encountered the acronym NAD+. Featured in longevity research, biohacking circles, and an increasing number of medical practices, NAD+ therapy has moved from the fringes of experimental science into mainstream integrative medicine.

But behind the buzzwords lies a genuinely fascinating molecule with a critical role in nearly every biological process that keeps you alive and functioning.

At The Confidence Lab in Powell, Ohio, we offer NAD+ infusion therapy as part of our evidence-based wellness services. This article explains exactly what NAD+ therapy is, what the science says, and what you can realistically expect from treatment.

The most well-known role of NAD+ is in cellular energy production. Inside your mitochondria, the energy-producing structures within every cell, NAD+ is essential for the metabolic pathways that convert the food you eat into ATP, the molecular currency your body uses for energy. When NAD+ levels are low, mitochondrial function suffers, and you may experience fatigue, brain fog, and reduced physical performance even when you are getting adequate sleep and nutrition.

NAD+ also plays a central role in DNA repair. Every day, your cells sustain tens of thousands of instances of DNA damage from normal metabolic processes, environmental toxins, and UV exposure. A family of enzymes called PARPs relies on NAD+ to repair this damage. When NAD+ is depleted, DNA repair becomes less efficient, allowing damage to accumulate and contributing to cellular aging and dysfunction.

Perhaps most exciting from a longevity perspective, NAD+ activates a group of proteins called sirtuins. Often referred to as longevity genes, sirtuins regulate inflammation, protect against oxidative stress, maintain genomic stability, and influence metabolic function. Sirtuins are completely dependent on NAD+ to function, making NAD+ levels a rate-limiting factor in your body’s anti-aging defenses.

Research consistently shows that NAD+ levels decrease by approximately 50 percent between the ages of 40 and 60. This decline is not simply a consequence of aging but appears to be a contributing cause. As NAD+ drops, mitochondrial function deteriorates, DNA repair becomes less efficient, sirtuin activity decreases, and inflammatory pathways become more active.

The result is a cascade of cellular dysfunction that manifests as the familiar signs and symptoms of aging: fatigue, cognitive decline, slower recovery, metabolic changes, and increased vulnerability to chronic disease.

Several factors accelerate NAD+ depletion beyond normal aging. Chronic stress increases the demand for NAD+ by activating repair pathways that consume it. Poor sleep disrupts NAD+ synthesis, which follows a circadian rhythm. Excessive alcohol consumption depletes NAD+ because your liver requires large amounts of it to process alcohol. Even overeating places additional metabolic demands on NAD+ stores.

This understanding has led researchers and clinicians to a compelling question: if declining NAD+ contributes to aging and dysfunction, can replenishing it slow or reverse those effects? While the research is still evolving, the early evidence and clinical observations are promising enough that NAD+ therapy has become one of the fastest-growing treatments in integrative and functional medicine.

A typical NAD+ infusion session takes approximately two to four hours, depending on the dose. We offer both 250mg and 500mg infusion options, with the appropriate dose determined during your consultation based on your health goals, current health status, and previous experience with NAD+ therapy.

The infusion is administered slowly because rapid delivery can cause temporary side effects including flushing, nausea, and chest tightness. Our experienced providers carefully control the infusion rate to ensure client comfort.

During your session, you are seated comfortably in our treatment area with access to amenities to make the experience as pleasant as possible. Many clients use the time to read, work on a laptop, or simply rest. Some clients experience a noticeable increase in mental clarity and energy even during the infusion, while others notice the effects more gradually over the following 24 to 48 hours.

For optimal results, we often recommend an initial series of three to four infusions spaced one to two weeks apart, followed by monthly maintenance sessions. This approach allows NAD+ levels to build up and stabilize, rather than relying on a single session to produce lasting effects. Your provider will work with you to develop a treatment schedule that aligns with your goals and lifestyle.

Human research is earlier in its development but growing. Studies on NAD+ precursors like NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) have shown that oral supplementation can raise blood NAD+ levels in humans. Clinical observations from IV NAD+ therapy, while not yet supported by large-scale randomized controlled trials, consistently report improvements in energy, mental clarity, sleep quality, and general well-being.

It is important to approach NAD+ therapy with appropriate expectations. The Confidence Lab practices evidence-based medicine, which means we are transparent about what the current research supports and where knowledge gaps remain. NAD+ therapy is not a proven cure for any specific disease. It is a wellness intervention supported by strong mechanistic science and encouraging clinical observations, offered as part of a comprehensive approach to health optimization.

We believe in being honest with our clients about the state of the evidence. The biological rationale for NAD+ therapy is robust, the safety profile is favorable, and the clinical observations are consistently positive. At the same time, this is a field where the science is rapidly evolving, and we stay current with the latest research to ensure our protocols reflect the best available evidence.

Individuals experiencing cognitive decline or brain fog frequently report enhanced mental clarity and focus following NAD+ therapy. The brain is one of the most metabolically active organs in the body and is particularly sensitive to NAD+ depletion. Supporting neuronal energy production and DNA repair through NAD+ replenishment can have noticeable cognitive benefits.

Athletes and active individuals seeking enhanced recovery and performance are another group that responds well to NAD+ therapy. By supporting mitochondrial function and reducing oxidative stress, NAD+ can improve recovery time after intense training and support overall physical performance. Some clients incorporate NAD+ infusions into their training schedules as part of a broader performance optimization strategy.

Finally, clients interested in proactive longevity and anti-aging often choose NAD+ therapy as part of a comprehensive wellness plan. By addressing one of the fundamental mechanisms of cellular aging, NAD+ therapy offers a biologically rational approach to supporting long-term health. When combined with other lifestyle interventions such as proper nutrition, exercise, and stress management, NAD+ therapy can be a powerful component of a whole-person approach to aging well.
