NAD+ and Anti-Aging
Why a coenzyme you’ve never thought about sits at the center of longevity research — and what NAD+ therapy can honestly do for healthy aging.
Written and medically reviewed by Charles Kamen, MD, board-certified neurologist ·
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that is essential for energy metabolism, and tissue levels decline with age — which is why it has become central to longevity research. One distinction matters up front: NAD+ is a coenzyme, not a peptide and not a hormone. Plenty of clinics blur that line.
The interesting part is the biology. NAD+ fuels the enzymes that produce cellular energy and supports the repair-and-maintenance machinery of the cell. The overstated part is the marketing: NAD+ does not “turn back the clock.” The honest goal is supporting cellular energy and healthspan, not reversing aging.
What NAD+ Therapy Is Studied For
Supporting cellular energy metabolism, which the age-related decline in NAD+ can blunt.
Supplying substrate for the cellular repair and maintenance enzymes that depend on NAD+.
Supporting recovery and mental clarity for some patients — individual response varies.
A delivery choice — IV NAD+ versus oral NMN/NR precursors — matched to your goals at evaluation.
NAD+ IV therapy vs NMN and NR precursors
There are two common ways to address declining NAD+. NAD+ IV therapy delivers NAD+ directly into the bloodstream, bypassing digestion. NMN and NR are oral precursors the body converts toward NAD+ — more convenient, and an active research area. We break down the molecules side by side on NAD vs NMN, and you can read more about in-clinic delivery on NAD+ IV therapy.
NAD+ also rarely works alone. It is usually one part of a longevity plan that may include anti-aging peptides, MOTS-c, 5-Amino-1MQ, and attention to cellular health. For the deeper science, see our blog on NAD+ and aging.
Where the evidence stands
Much of the most striking NAD+ data comes from laboratory and animal research; the human longevity evidence is still developing. That does not make NAD+ uninteresting — it makes honesty essential. We are explicit about what is established versus what is promising, and NAD+ is offered as physician- supervised support for cellular energy and healthy aging, never as a cure for aging.
NAD+ and Anti-Aging FAQ
What is NAD+ and why is it linked to aging?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that is essential for energy metabolism and for enzymes involved in cellular repair and maintenance. Tissue NAD+ levels decline with age, which is why NAD+ has become central to longevity research. It is a coenzyme, not a peptide or a hormone — an important distinction many clinics get wrong.
Does NAD+ therapy reverse aging?
No. NAD+ does not reverse aging, and the strongest human evidence is still developing. NAD+ IV therapy and NAD+ precursors (like NMN and NR) are studied for supporting cellular energy metabolism and addressing the age-related decline in NAD+, but claims that NAD+ "turns back the clock" outrun the science. The honest goal is supporting cellular energy and healthspan, not a fountain of youth.
What is the difference between NAD+ IV therapy and NMN supplements?
NAD+ IV therapy delivers NAD+ directly into the bloodstream, bypassing digestion. NMN and NR are oral precursors the body converts toward NAD+. IV may raise availability more directly; oral precursors are more convenient and are an active area of research. We compare the molecules in detail on our NAD vs NMN page, and the right choice depends on your goals and evaluation.
Is NAD+ IV therapy safe?
For most healthy adults, physician-supervised NAD+ IV therapy is generally well tolerated; infusing too quickly can cause transient flushing, nausea, or chest tightness, which is why the drip rate is controlled and supervised. As with any therapy, safety depends on your health history and oversight. NAD+ IV therapy at LiveNow Longevity is administered under physician supervision after an evaluation.
Who is a candidate for NAD+ therapy in Las Vegas?
Adults interested in supporting cellular energy, recovery, and healthy aging may be candidates, but candidacy is decided at a medical evaluation — not by a menu. Dr. Charles Kamen, MD reviews your history and goals and recommends NAD+ only when it is a reasonable fit, often alongside other longevity strategies rather than as a standalone "anti-aging cure."
