What Is NAD+ IV Therapy?
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every living cell, essential for hundreds of metabolic processes including energy production, DNA repair, cellular signaling, and gene expression. As we age — and during chronic illness — NAD+ levels decline significantly, contributing to cellular dysfunction, fatigue, cognitive decline, and accelerated aging.
NAD+ IV therapy delivers this critical coenzyme directly into the bloodstream via intravenous infusion, bypassing the digestive system for maximum bioavailability. This approach allows cells to rapidly replenish their NAD+ stores, supporting mitochondrial function and cellular repair mechanisms that oral supplementation cannot match.
At St. George Hospital (Klinik St. Georg) in Bad Aibling, Germany, NAD+ IV therapy is integrated into our treatment protocols for chronic fatigue, neurodegenerative conditions, post-COVID recovery, addiction recovery, and longevity medicine. Dr. Julian Douwes, Chief Medical Officer, considers NAD+ restoration a foundational element of cellular recovery: “When cells cannot produce energy efficiently, every system in the body suffers. NAD+ is the molecule that bridges the gap between cellular energy crisis and clinical recovery.”
How Does NAD+ Work in the Body?
NAD+ participates in two fundamental categories of cellular reactions:
Energy Metabolism
NAD+ is essential for the electron transport chain in mitochondria — the process by which cells convert nutrients into ATP (adenosine triphosphate), the universal energy currency. Without adequate NAD+, mitochondria cannot function efficiently, leading to reduced energy production at the cellular level. This manifests clinically as fatigue, brain fog, muscle weakness, and reduced exercise tolerance.
Cellular Repair and Signaling
NAD+ serves as a substrate for several important enzyme families:
- Sirtuins: A family of proteins that regulate aging, inflammation, and stress resistance. Sirtuins depend entirely on NAD+ for their activity. Research published in Cell Metabolism has highlighted the role of NAD+-sirtuin signaling in aging and disease
- PARPs (Poly ADP-Ribose Polymerases): Enzymes critical for DNA repair. DNA damage from oxidative stress, infection, or aging activates PARPs, which consume NAD+ in the repair process
- CD38: An enzyme involved in immune cell signaling that also consumes NAD+. Chronic inflammation drives up CD38 activity, further depleting NAD+ stores
This creates a vicious cycle in chronic illness: disease drives NAD+ depletion, and NAD+ depletion impairs the body’s ability to fight disease and repair damage.
Benefits of NAD+ IV Therapy
Energy and Mitochondrial Function
The most immediate and commonly reported benefit of NAD+ infusion is improved energy. By restoring mitochondrial NAD+ levels, cells resume efficient ATP production. Patients frequently report:
- Reduced fatigue — often within hours to days of treatment
- Improved physical endurance
- Greater mental clarity and focus
- Better exercise recovery
Cognitive Function and Brain Health
The brain is one of the most metabolically demanding organs, consuming approximately 20% of the body’s total energy despite accounting for only 2% of body weight. NAD+ depletion disproportionately affects brain function, contributing to:
- Brain fog and cognitive sluggishness
- Difficulty with concentration and memory
- Reduced processing speed
NAD+ IV therapy supports neuronal energy metabolism and may activate neuroprotective sirtuin pathways. Patients with post-COVID brain fog, chronic fatigue-related cognitive impairment, and age-related cognitive decline often report meaningful improvement.
Cellular Repair and Anti-Aging
By fueling sirtuin and PARP activity, NAD+ supports:
- DNA repair and genomic stability
- Reduced cellular senescence (the accumulation of dysfunctional, aging cells)
- Improved stem cell function
- Enhanced autophagy (cellular housekeeping)
These mechanisms underpin the growing interest in NAD+ as a longevity intervention.
Immune Function
NAD+ influences immune cell metabolism and function. Adequate NAD+ levels are required for proper T-cell activation, macrophage function, and inflammatory resolution. For patients with chronic infections such as Lyme disease or immune dysfunction following COVID-19, NAD+ restoration can support immune recovery.
Addiction and Neurological Recovery
NAD+ IV therapy has been used in addiction medicine to support neurological recovery from substance dependence. By restoring neurotransmitter balance and mitochondrial function in the brain, NAD+ can help reduce cravings and support cognitive recovery during withdrawal and early sobriety.
Who Is NAD+ IV Therapy For?
NAD+ IV therapy may benefit patients with:
- Chronic fatigue: Including chronic fatigue syndrome (ME/CFS) and fatigue secondary to chronic illness
- Post-COVID syndrome: Brain fog, fatigue, and functional decline following SARS-CoV-2 infection
- Neurodegenerative conditions: Including early Parkinson’s and Alzheimer’s disease (as a supportive therapy)
- Chronic infections: Lyme disease, bartonella, and other persistent infections that deplete cellular energy
- Longevity and preventive medicine: Proactive NAD+ replenishment to support healthy aging
- Addiction recovery: Alcohol, opioid, and stimulant dependence
- Athletic performance and recovery: High-level athletes seeking enhanced recovery and endurance
What Does NAD+ IV Therapy Cost?
NAD+ IV therapy costs vary significantly depending on the dose, duration, and clinical setting:
- Standard NAD+ IV infusion (250-500 mg): Typically ranges from $250-$750 per session in the United States, and comparable pricing in European clinics
- High-dose NAD+ (750-1000 mg): $750-$1,500 per session
- Multi-session protocols (5-10 days): Total costs of $3,000-$10,000 depending on dose and frequency
At St. George Hospital, NAD+ infusions are typically part of a comprehensive inpatient treatment program rather than a standalone service. The cost is included within the overall treatment plan, which is tailored to each patient’s diagnosis and goals. We provide detailed cost estimates during the consultation process.
Important: NAD+ IV therapy is generally not covered by insurance in most countries. However, some private insurance plans may cover it when prescribed as part of a medically necessary treatment protocol. Our international patient coordinators can assist with documentation for insurance claims.
What to Expect During NAD+ IV Therapy
Before Treatment
Your physician will assess your medical history, current health status, and treatment goals to determine the appropriate NAD+ dose and protocol. Blood work may be performed to evaluate baseline metabolic markers.
During the Infusion
- Duration: NAD+ infusions typically take 2-4 hours, depending on dose. Higher doses require slower infusion rates for comfort
- Sensation: Some patients experience temporary chest tightness, abdominal discomfort, or a flushing sensation during infusion. These effects are dose-rate dependent and resolve when the infusion rate is slowed
- Setting: At St. George Hospital, infusions are administered in a comfortable clinical setting with medical supervision
After Treatment
Many patients notice increased mental clarity and energy within 24-48 hours of their first infusion. The effects tend to be cumulative — most protocols involve multiple sessions over 5-14 days. Some patients describe a “cellular reboot” sensation as mitochondrial function improves.
Side Effects of NAD+ IV Therapy
NAD+ IV therapy is generally well-tolerated. The most common side effects are infusion-related and transient:
- Chest or abdominal pressure: The most frequently reported side effect, caused by rapid infusion. Resolving by slowing the drip rate
- Nausea: Usually mild, often responds to rate reduction
- Flushing and warmth: Temporary vasodilation
- Muscle cramping: Occasionally reported, may relate to electrolyte shifts
- Headache: Sometimes occurs in the first 1-2 sessions
- Fatigue after the first session: Paradoxically, some patients feel tired initially as the body adjusts to increased metabolic activity
Serious adverse events are rare when NAD+ is administered by experienced medical professionals in an appropriate clinical setting.
NAD+ IV vs. Oral NAD+ Supplements
Oral NAD+ precursors — such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) — have gained significant popularity as supplements. How do they compare to IV NAD+?
- Bioavailability: IV NAD+ delivers the coenzyme directly to the bloodstream at 100% bioavailability. Oral precursors must be absorbed, metabolized, and converted to NAD+ — a process with variable efficiency
- Speed of effect: IV NAD+ produces effects within hours to days. Oral supplements may take weeks to produce noticeable changes
- Dose achievable: IV administration can deliver therapeutic doses (250-1000 mg) that would be impossible to achieve orally
- Clinical context: For patients with severe NAD+ depletion (chronic illness, post-COVID, ME/CFS), IV administration provides the rapid and substantial replenishment that oral supplements cannot match
That said, oral NAD+ precursors may be valuable for maintenance between IV treatments and for general wellness optimization. Research published in Nature Communications has explored the efficacy of various NAD+ precursor strategies.

Frequently Asked Questions
How long do the effects of NAD+ IV therapy last?
The duration of benefit varies by individual and condition. Many patients report sustained improvement for 2-4 weeks after a multi-day IV protocol. For chronic conditions, periodic maintenance infusions (monthly or quarterly) may be recommended. Combining IV NAD+ with oral precursor supplements and lifestyle optimization can extend the benefits.
Is NAD+ IV therapy safe?
Yes, when administered by qualified medical professionals. NAD+ is a naturally occurring molecule in the body, and IV administration replenishes stores that are already depleted. Side effects are generally mild and infusion-rate dependent. Patients with certain conditions should be evaluated carefully before treatment, which is why we recommend physician-supervised administration rather than unsupervised wellness infusions.
Can NAD+ IV therapy help with aging?
The science of NAD+ in aging is compelling and growing. NAD+ decline is considered one of the hallmarks of biological aging, and restoring NAD+ levels has been shown in preclinical research to improve mitochondrial function, activate longevity-associated sirtuins, and enhance DNA repair. While human clinical trials are ongoing, the biological rationale for NAD+ as a longevity intervention is strong.
How is NAD+ IV therapy different from a Myers’ cocktail or vitamin drip?
NAD+ IV therapy targets a specific and fundamental metabolic pathway — cellular energy production and repair. While Myers’ cocktails and vitamin infusions provide micronutrients, NAD+ addresses the core machinery of the cell. They are complementary rather than competing approaches, and at St. George Hospital, NAD+ is often combined with high-dose vitamin C and other infusions as part of a comprehensive protocol.
