NAD+ IV Therapy Las Vegas: A Physician's Complete Guide
By Charles Kamen, MD, board-certified neurologist
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, and its supply falls sharply with age — by middle age, NAD+ pools are typically about 50% lower than they were in young adulthood.[3] That decline is a major reason NAD+ IV therapy has become one of the most requested longevity treatments in Las Vegas and Henderson.
Dr. Charles Kamen, MD, a board-certified neurologist at LiveNow Longevity in Las Vegas, evaluates every patient before adding NAD+ to a protocol. This guide explains what NAD+ does, what the research supports, and how a physician approaches it. Individual results vary, and we do not promise specific outcomes.
What is NAD+, and what does it do?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in every cell that powers mitochondrial energy production, DNA repair, and sirtuin activation. Because it sits at the intersection of these core pathways, NAD+ availability shapes how efficiently cells make energy and repair themselves.[1]
- Mitochondrial energy: NAD+ carries electrons through the electron transport chain, the process that generates cellular ATP.
- DNA repair: NAD+ fuels PARP enzymes that detect and mend damaged strands of DNA.
- Sirtuin activation: sirtuins — enzymes that regulate metabolism and stress resistance — depend on NAD+ to function.[3]
- Cellular resilience: NAD+ helps maintain the redox balance cells rely on to withstand everyday stress.
Does NAD+ really decline with age?
Yes. NAD+ levels drop as we age — by middle age, cellular NAD+ pools are typically about 50% lower than in young adulthood.[3] The fall reflects both reduced production and rising demand from enzymes that consume NAD+, leaving less to power energy metabolism and repair.
With age and chronic inflammation, NAD+-consuming enzymes such as PARPs and CD38 become more active, drawing down the same pool the mitochondria and sirtuins depend on. This is why NAD+ is one of the most studied molecules in longevity science, and why restoring it is an area of active research.
How does NAD+ IV therapy work?
NAD+ IV therapy delivers NAD+ directly into the bloodstream, bypassing gut absorption. The rationale is that IV delivery can raise circulating NAD+ more effectively than oral precursors such as NMN or NR, though research comparing bioavailability is still developing.[2]
At our Las Vegas NAD+ therapy clinic, NAD+ IV therapy is offered only after a medical evaluation. It is typically administered as a slow infusion over 1-4 hours per session, with frequency determined by your individual protocol.
IV NAD+ vs. oral NMN and NR
IV NAD+ and oral precursors raise NAD+ by different routes. Oral NMN and NR are absorbed through the gut and converted to NAD+ inside cells, while IV NAD+ enters circulation directly. Head-to-head evidence on which approach raises tissue NAD+ most effectively is still emerging, so the right choice depends on your goals, tolerance, and labs.[2]
What can NAD+ support — energy, recovery, and the brain?
Because NAD+ is central to how cells generate energy, the questions patients ask most are about energy, recovery, and mental sharpness. NAD+ powers the mitochondria that fuel high-demand tissues, including the brain, so cellular energy status is closely tied to how energized, recovered, and clear-headed a person feels.
As a neurologist, Dr. Kamen pays particular attention to the brain's energy budget — the nervous system is one of the most metabolically expensive tissues in the body, and it runs on the same mitochondrial machinery NAD+ supports. Research into these benefits is ongoing, individual results vary, and we do not promise specific outcomes.
What does a physician-led Las Vegas NAD+ evaluation include?
At LiveNow Longevity, NAD+ therapy is considered only after a complete medical evaluation. The initial consultation is $88 and includes a clinical review with Dr. Charles Kamen, MD, a look at your history and medications, comprehensive lab work, and a goal-based discussion.
NAD+ is not a stand-alone wellness service — it requires physician supervision, and whether it belongs in your plan depends on your labs, medications, and goals. We do not promise specific outcomes from NAD+ or any other therapy. A typical evaluation covers:
- Clinical consultation with Dr. Charles Kamen, MD, board-certified neurologist.
- Review of your medical history and current medications.
- A comprehensive lab panel to establish your baseline.
- A goal-based discussion of whether NAD+ fits your longevity plan.
Key Takeaways
- NAD+ is a coenzyme involved in mitochondrial energy production, DNA repair, and sirtuin activation.
- By middle age, cellular NAD+ pools are typically about 50% lower than in young adulthood.
- IV delivery bypasses gut absorption, sending NAD+ directly into the bloodstream.
- NAD+ IV therapy is typically given as a slow infusion over 1-4 hours per session.
- NAD+ powers the cellular energy machinery patients associate with energy, recovery, and mental clarity — outcomes are individual and not promised.
- At LiveNow Longevity, NAD+ is considered only after an $88 physician evaluation, not as a stand-alone wellness service.
Common Questions
How much does NAD+ IV therapy cost in Las Vegas?
Protocol costs depend on your dose, frequency, and individualized plan, so there is no single price for NAD+ IV therapy. The initial medical evaluation is $88 and includes lab work and a consultation with Dr. Kamen. For related pricing context, see our <a href="/blog/peptide-therapy-cost-las-vegas">peptide therapy cost in Las Vegas guide</a>.
How long before I notice changes from NAD+?
Individual response varies. Some patients report subjective changes such as energy within 2-4 weeks, while lab-based changes typically take longer to appear. NAD+ works at the cellular level over time rather than instantly, and we do not promise specific outcomes. Dr. Kamen tracks your response against your baseline labs and goals.
Can NAD+ IV therapy improve energy and mental clarity?
NAD+ powers the mitochondria that supply energy to high-demand tissues, including the brain, so many patients ask about energy, recovery, and mental clarity. Research into these benefits is still developing, and we do not promise specific outcomes. Dr. Kamen, a neurologist, evaluates whether NAD+ fits your individual energy and cognitive goals.
Is NAD+ IV therapy safe?
NAD+ IV therapy should be given only under physician supervision after a medical evaluation, not as a stand-alone wellness service. Administering it as a slow infusion over 1-4 hours helps limit side effects such as flushing or nausea. Dr. Kamen reviews your history, medications, and labs before recommending any protocol.
Is oral NMN or NR as effective as IV NAD+?
Oral precursors such as NMN and NR raise NAD+ through the gut, while IV NAD+ enters the bloodstream directly, and research comparing their bioavailability is still developing. Neither is automatically better; the right approach depends on your goals, tolerance, and labs, which Dr. Kamen reviews during your $88 evaluation.
Do you offer NAD+ therapy to Henderson patients?
Yes. Many of our NAD+ patients come from Henderson, Green Valley, Anthem, and Seven Hills, all a short drive from the Las Vegas clinic. NAD+ protocols are the same regardless of which community you travel from. See our <a href="/peptide-clinic-henderson">Henderson peptide clinic</a> page for details.
NAD+ IV therapy is one of the most studied longevity interventions of the last decade, but the right way to approach it is through a complete medical evaluation by a physician who designs protocols individually. Schedule at our Las Vegas peptide clinic or our Henderson peptide clinic.
