Our NAD+ therapy protocols target:
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It plays a central role in energy metabolism, DNA repair, cellular signaling, and the regulation of aging-related pathways. Without adequate NAD+ levels, mitochondria — the energy generators inside your cells — cannot function efficiently, leading to fatigue, cognitive decline, and accelerated biological aging.
NAD+ levels decline naturally with age. By the time most adults reach their 40s, NAD+ levels have dropped by approximately 50% compared to their 20s. This decline is associated with a wide range of age-related conditions: decreased mental clarity, reduced physical stamina, impaired immune function, slower recovery from illness or injury, and increased susceptibility to metabolic disorders.
At LiveWell21 in Las Vegas, Dr. Charles Kamen, MD uses NAD+ therapy as a cornerstone of his longevity and optimization protocols. With training from Albert Einstein College of Medicine and Yale-New Haven Hospital, Dr. Kamen designs individualized NAD+ treatment plans based on lab work, clinical assessment, and measurable outcomes — not trends or marketing claims.
Every NAD+ protocol at LiveWell21 is physician-supervised from start to finish. You receive direct care from Dr. Kamen, with dosing and administration routes tailored to your specific health profile and goals. This is concierge-level medicine: thorough, personalized, and evidence-based.
NAD+ is essential for hundreds of enzymatic reactions in the body. Its primary roles include:
By restoring NAD+ levels through targeted therapy, we can support these fundamental biological processes and help the body function more efficiently at every level — from the cellular to the systemic.
Dr. Kamen offers multiple NAD+ delivery methods, selected based on your clinical needs, health goals, and lifestyle preferences. Each protocol is designed to maximize bioavailability and therapeutic benefit.
Primary use: Maximum bioavailability, rapid restoration, intensive protocols
Intravenous NAD+ infusion delivers the coenzyme directly into your bloodstream, bypassing the digestive system entirely. This achieves 100% bioavailability and allows for precise dosing. IV infusions are typically administered over 2-4 hours in our comfortable clinical setting. Standard protocols range from 250mg to 1000mg per session, depending on your goals and tolerance. IV NAD+ is particularly effective for patients experiencing significant fatigue, cognitive decline, or those beginning an intensive anti-aging protocol.
Primary use: Maintenance therapy, convenience, ongoing optimization
Subcutaneous NAD+ injections offer a practical alternative to IV infusion for patients who have completed an initial loading phase or prefer a more convenient administration method. Self-administered at home using a small insulin-style needle, these injections provide excellent absorption and can be integrated into a daily or weekly routine. Dr. Kamen provides thorough self-injection training and monitors your response through regular lab work.
Primary use: Oral supplementation, foundational support, long-term maintenance
NAD+ precursors — including nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) — are oral supplements that the body converts into NAD+. While less immediately bioavailable than IV or injection routes, precursors provide convenient daily support for maintaining NAD+ levels between clinical treatments. Dr. Kamen selects pharmaceutical-grade precursors and monitors their effectiveness through lab markers including intracellular NAD+ levels.
Primary use: Comprehensive optimization, synergistic benefits
For patients pursuing aggressive longevity optimization, Dr. Kamen designs combination protocols that pair NAD+ therapy with complementary treatments. These may include peptide therapy (CJC-1295/Ipamorelin for growth hormone support, BPC-157 for tissue repair), IV micronutrient infusions (glutathione, vitamin C, B-complex), and targeted supplementation. The combination approach addresses multiple aging pathways simultaneously, producing synergistic results that exceed what any single therapy achieves alone.
NAD+ therapy is appropriate for a wide range of adults seeking to optimize their health, slow biological aging, or address specific clinical concerns. Common candidates include:
During your initial consultation, Dr. Kamen reviews comprehensive lab work — including intracellular NAD+ levels when appropriate — medical history, and your specific health goals to determine whether NAD+ therapy is right for you and which protocol will deliver the best results.
Your first visit includes a detailed health history review, physical assessment, and comprehensive lab panel. Dr. Kamen personally conducts every consultation — you will never be seen by a nurse practitioner or physician assistant for your evaluation. This initial visit typically lasts 45-60 minutes and covers your current health status, energy patterns, cognitive function, sleep quality, and specific goals for NAD+ therapy.
Based on your lab results and clinical assessment, Dr. Kamen designs a personalized NAD+ protocol. This includes the delivery method (IV, injection, oral, or combination), dosing schedule, expected timeline for results, and any complementary therapies that would enhance your outcomes. You receive clear instructions on what to expect during treatment, including potential side effects and how to manage them.
Most NAD+ protocols begin with a loading phase to rapidly restore depleted levels. For IV protocols, this typically involves 3-5 infusion sessions over 1-2 weeks. For injection protocols, daily or every-other-day administration during the first 2-4 weeks. Dr. Kamen monitors your response closely during this phase, adjusting dosing based on both subjective improvements and objective lab markers.
After the initial loading phase, your protocol transitions to a maintenance schedule designed to sustain optimal NAD+ levels long-term. This may include weekly or bi-weekly IV sessions, daily subcutaneous injections, oral precursor supplementation, or a combination. Follow-up labs at 6-8 week intervals track your NAD+ levels, metabolic markers, and overall progress. Protocols evolve as your body responds and your goals change.

NAD+ (Nicotinamide Adenine Dinucleotide) therapy represents a breakthrough in regenerative medicine, offering patients a way to restore cellular energy, enhance cognitive function, and support recovery from various chronic conditions. At Live Now Longevity, Dr. Charles Kamen brings his neurological expertise to guide patients through evidence-based NAD+ treatment protocols designed to address the root causes of cellular aging and dysfunction.
NAD+ is a critical coenzyme found in every cell of your body. It plays an essential role in converting nutrients from food into cellular energy (ATP) through a process called cellular respiration. Think of NAD+ as a molecular shuttle that carries electrons within mitochondria—the powerhouses of your cells—allowing them to generate the energy your body needs to function at optimal levels.
As a neurology specialist, Dr. Kamen recognizes that the brain is particularly vulnerable to NAD+ depletion. The brain consumes approximately 20% of your body’s energy despite comprising only 2% of body weight. When NAD+ levels decline, neurons lose their ability to produce sufficient ATP, leading to cognitive decline, fatigue, and impaired neural repair mechanisms.
Live Now Longevity offers multiple delivery methods to restore NAD+ levels, allowing Dr. Kamen to customize treatment protocols based on each patient’s condition, goals, and medical history.
Intravenous (IV) NAD+ Infusion: Our primary treatment method delivers NAD+ directly into the bloodstream, achieving the highest bioavailability. IV infusions allow for precise dosing and rapid cellular penetration.
Subcutaneous Injection: For patients who prefer home-based care or require maintenance therapy between IV sessions, subcutaneous NAD+ injections offer consistent delivery with minimal discomfort.
Oral Supplementation: While oral NAD+ precursors (such as NR or NMN) have lower bioavailability than IV delivery, they serve an important role in maintaining NAD+ levels between intensive treatments.
Dr. Charles Kamen, board-certified neurologist and graduate of Albert Einstein College of Medicine, brings specialized knowledge in how NAD+ depletion affects neurological health. Through NAD+ therapy, Dr. Kamen helps patients address neurological aging at the cellular level, potentially preventing or slowing cognitive decline before it becomes symptomatic.
NAD+ therapy benefits patients with diverse health concerns. Dr. Kamen carefully evaluates each patient’s condition to determine whether NAD+ therapy is appropriate and how to integrate it with other treatments.
Initial Consultation: Your journey begins with a comprehensive consultation with Dr. Kamen. He will review your medical history, perform an evaluation, and discuss your health goals.
IV Infusion Process: NAD+ IV infusions are performed in our comfortable, clinical setting. The infusion typically takes 2-4 hours, depending on the dosage and your individual response. During the infusion, you’ll relax in a private bay while NAD+ flows directly into your bloodstream.
Injection Protocols: For subcutaneous injections, Dr. Kamen or his clinical staff will teach you proper injection technique if you’re administering doses at home.
Treatment Timeline: Most patients begin noticing improvements within 1-2 weeks of initiating therapy. Full benefits typically develop over 4-12 weeks as cellular NAD+ stores are replenished.
NAD+ levels naturally decline with age—a process that accelerates significantly after age 40. Research shows that NAD+ concentrations can drop by up to 50% between age 20 and 60.
Several factors accelerate NAD+ depletion: chronic stress increases demand for NAD+-dependent DNA repair, sleep deprivation disrupts circadian NAD+ rhythms, chronic inflammation consumes NAD+ through PARP enzyme activation, and various medical conditions further compromise NAD+ metabolism.
Recent research demonstrates that restoring NAD+ levels can reverse many markers of cellular aging. Studies show that NAD+ therapy enhances mitochondrial function, improves DNA repair capacity, activates sirtuins and other longevity pathways, and reduces age-related inflammation.
These declines correlate strongly with increases in age-related diseases and functional decline.
NAD+ therapy has an excellent safety profile. Dr. Kamen carefully screens all patients to ensure suitability for treatment and monitors for any adverse effects.
Common Mild Effects (usually temporary): Some patients experience brief flushing, mild warmth, or tingling sensations during IV infusions. These typically subside within minutes to an hour.
Rare Side Effects: Headaches, mild nausea, or transient blood pressure changes can occur but are uncommon.
Important Contraindications: NAD+ therapy may not be appropriate for patients with certain conditions. Pregnant and breastfeeding women should not use NAD+ therapy. Patients with severe kidney disease, heart failure, or uncontrolled hypertension require special evaluation.
NAD+ therapy benefits a wide range of patients. Ideal candidates include:
Most patients report initial improvements in energy and mental clarity within 1-2 weeks. More substantial benefits typically develop over 4-12 weeks as cellular NAD+ stores are fully replenished.
NAD+ therapy restores depleted levels, but NAD+ will gradually decline again over time. This is why maintenance therapy—typically monthly or biweekly treatments—is recommended to sustain benefits.
Yes. Dr. Kamen often recommends combining NAD+ with other regenerative therapies, supplements, or treatments. NAD+ can enhance the effectiveness of other interventions, particularly those addressing mitochondrial function or cellular repair.
No. NAD+ is a naturally occurring molecule produced by your body. It does not show up on standard drug tests and is not a controlled substance.
Dr. Charles Kamen brings specialized neurological training and expertise to NAD+ therapy. He personalizes every protocol based on your specific condition, medical history, and goals. Live Now Longevity uses pharmaceutical-grade NAD+ and maintains the highest clinical standards.
