If you follow longevity science at all, you've almost certainly encountered three letters: NAD+. Short for nicotinamide adenine dinucleotide, this coenzyme is present in every living cell in your body and plays a central role in energy metabolism, DNA repair, and cellular signaling. Without adequate NAD+, your cells simply cannot function at full capacity.
The challenge is that NAD+ levels decline significantly with age. Research published in Cell Metabolism suggests that by middle age, NAD+ concentrations can drop by as much as 50 percent compared to your twenties. This decline is now understood to be one of the key molecular drivers of aging itself — not merely a symptom of getting older, but a cause of the metabolic dysfunction, cognitive decline, and tissue degeneration we associate with it.
NAD+ operates as a critical shuttle in your mitochondria, the organelles responsible for converting the food you eat into the ATP your cells use for energy. Every time your cells produce energy, NAD+ is there facilitating the electron transport chain. When NAD+ levels are low, mitochondrial efficiency drops — and you feel it as fatigue, brain fog, and slower recovery.
But energy production is only part of the story. NAD+ also activates a family of proteins called sirtuins, sometimes referred to as "longevity genes." Sirtuins regulate inflammation, circadian rhythm, stress resistance, and DNA repair. They are, in many ways, your body's internal maintenance crew — and they require NAD+ as fuel to do their work.
NAD+ is not a supplement that adds something foreign to your body. It restores something your body already produces — just not in sufficient quantities as you age.
NAD+ also activates another enzyme called PARP-1, which detects and repairs damaged DNA. As DNA damage accumulates with age, PARP-1 consumes more and more NAD+, creating a vicious cycle: the more damage you have, the more NAD+ you use, and the less remains for other critical functions.
Clinical research and emerging evidence point to several meaningful benefits of restoring NAD+ levels:
This is where nuance matters. Oral NAD+ precursors — nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) — have gained popularity as supplements. They work by providing the raw materials your body uses to synthesize NAD+. Research shows they can modestly raise NAD+ levels over time, and they are convenient and well-tolerated.
IV NAD+ therapy is a different approach. By delivering NAD+ directly into the bloodstream, IV administration bypasses the digestive system entirely and achieves significantly higher bioavailability. A 2019 study in the Journal of Translational Medicine demonstrated that IV NAD+ produced rapid, measurable increases in plasma NAD+ levels — far exceeding what oral supplementation achieves.
IV NAD+ is particularly valuable for individuals with significantly depleted levels, those seeking faster results, or patients using NAD+ therapeutically for specific conditions. For ongoing maintenance, many practitioners recommend a combination: periodic IV infusions supplemented by daily oral precursors between sessions.
At ALYZE, NAD+ therapy is never a standalone treatment. It begins with your comprehensive bloodwork panel — processed in our CLIA-certified on-site lab — which gives your medical team a clear picture of your metabolic health, inflammation markers, and cellular function before recommending a protocol.
A typical NAD+ infusion session lasts between 90 minutes and three hours, depending on the dose. You'll be seated in one of our private treatment rooms — comfortable, quiet, designed to feel nothing like a clinical setting. Most members use the time to read, work, or simply rest. Some mild flushing or warmth during the infusion is normal and subsides quickly.
Your practitioner will monitor your response and adjust the drip rate as needed. Afterward, many members report an almost immediate sense of clarity and energy — though the deeper cellular benefits build over a series of sessions.
NAD+ therapy is not limited to any single demographic. That said, the members who tend to see the most dramatic results include:
The reason ALYZE exists is that no single therapy works in isolation. NAD+ can restore cellular energy — but if your hormones are dysregulated, your sleep architecture is broken, or your body is chronically inflamed from overtraining, you won't capture the full benefit. That's why every NAD+ protocol at ALYZE is built within the context of your full health picture: bloodwork, body composition, fitness data, and mental performance baseline.
It's the difference between taking a supplement and actually optimizing your biology. And it's the difference between a treatment and a system.
