NAD IV Therapy
"My brain doesn't work the way it used to — foggy, slow, unfocused. I want something that actually restores it."

Brain restoration. Cellular renewal. NAD IV.

NAD+ is the cellular cofactor essential for energy production, sirtuin regulation, and cognitive performance. IV delivery restores your natural reserves — reducing brain fog, improving concentration and memory, and supporting overall brain rejuvenation.

What it treats

NAD IV works on three levels: cellular energy, brain function, and recovery.

The real site uses NAD IV for brain restoration, addiction recovery, and depression support — three distinct applications of the same core mechanism: restoring NAD+ levels that have been depleted by aging, substance use, or chronic stress.

🧠
Brain Fog & Cognitive Restoration

NAD+ is a cellular cofactor that plays a critical role in sirtuin regulation — the proteins responsible for cognitive performance, DNA repair, and neurological resilience. Dozens of studies show NAD IV produces measurable reductions in brain fog, improved concentration and focus, better memory, and refreshed cognitive abilities. Many patients describe it as genuine brain rejuvenation.

Cellular Energy & Mitochondrial Function

NAD+ is the rate-limiting coenzyme in the conversion of food into body energy. As NAD levels decline with age — by roughly 50% between 40 and 60 — mitochondrial ATP production falls systemically. Restoring NAD+ through IV therapy directly improves the cellular energy production that determines physical and mental stamina.

🔄
Addiction Recovery Support

Alcohol and substance abuse severely deplete NAD+ levels and disrupt neurological function in ways that traditional medications struggle to address. NAD IV therapy replenishes natural reserves, eases withdrawal symptoms, minimizes relapse risk, detoxifies the body, and restores cell functioning — often more effectively than oral medications alone. Course duration typically 4–14 days for addiction recovery protocols.

😌
Depression & Mood Restoration

NAD+ directly stimulates serotonin production — the neurotransmitter at the center of mood regulation. Unlike antidepressants, which can reduce serotonin receptor sensitivity over time, NAD IV supports the natural serotonin synthesis pathway. Patients experiencing depression and anxiety linked to neurological NAD+ deficiency often respond well where pharmaceutical options have been insufficient.

🛡️
Neurodegenerative Disease Resistance

NAD deficiency undermines resistance to neurodegenerative diseases. By maintaining adequate NAD+ levels, IV therapy supports the sirtuin-mediated cellular repair processes that protect against age-related neurological decline. Used in anti-aging and longevity protocols for patients proactively supporting long-term brain health.

🔬
Sirtuin Regulation & Anti-Aging

Sirtuins are a family of proteins essential for a variety of physiological processes — they require NAD+ to function. As NAD declines with age, sirtuin activity falls, accelerating the cellular aging process. NAD IV therapy restores the NAD+ that sirtuins depend on — supporting DNA repair, metabolic efficiency, and cellular resilience at a biological level.

If your fatigue and brain fog haven't responded to sleep or supplements, the problem may be cellular — not behavioral.

NAD+ cannot be effectively restored through oral supplementation — bioavailability is poor and precursor conversion is limited. IV delivery is the only way to achieve therapeutic tissue concentrations rapidly.

How it works

Every cell needs it. Most of us are running low.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell. It is the central electron carrier in cellular respiration — the process by which cells convert nutrients (glucose, fatty acids, amino acids) into ATP, the actual energy currency the body uses. Without adequate NAD+, mitochondrial energy production falls. Since every tissue in the body relies on mitochondrial ATP, the result is systemic — fatigue, cognitive slowness, impaired recovery, and reduced cellular stress response.

NAD+ also activates sirtuins — a family of proteins involved in DNA repair, cellular stress response, and the regulation of metabolic pathways associated with aging and longevity. Sirtuin activity is directly proportional to NAD+ availability. The significant decline in NAD+ between ages 40 and 60 (approximately 50%) is therefore associated with the hallmarks of aging at the cellular level: impaired DNA repair, reduced metabolic efficiency, and declining cellular resilience.

The site also highlights two additional clinical applications. For addiction recovery: alcohol and substance abuse deplete NAD+ severely, and IV therapy replenishes reserves while easing withdrawal and detoxifying the body — a more targeted approach than oral medications. For depression: NAD+ stimulates serotonin production naturally, making it a meaningful adjunct for patients whose mood issues have a neurological-depletion component.

Why oral NAD+ precursors aren't enough

NMN and NR are oral NAD+ precursors that require conversion to NAD+ in tissues — a multi-step process with variable efficiency that produces a modest, gradual increase in NAD+ levels. IV NAD+ bypasses all conversion steps and delivers NAD+ directly into circulation at concentrations that are physiologically impossible to achieve orally. For patients with significant depletion or specific clinical goals, IV delivery is in a different category.

Side-by-side comparison

NAD IV vs. oral NAD+ precursors — the real difference.

Both increase NAD+ — but at fundamentally different magnitudes and timelines.

Feature NAD IV ★NMN / NR (Oral)
Delivery Oral — requires multi-step conversion
Absorption Variable, limited by gut/liver
Speed of effect Weeks of consistent use
NAD+ level achieved Modest increase
Infusion time Oral — no infusion needed
Frequency Daily oral supplement
Best for Gentle ongoing maintenance
The research is clear

NAD+ is at the center of cellular aging research.

The role of NAD+ in mitochondrial function, sirtuin activation, and DNA repair has made it one of the most studied molecules in longevity biology. IV delivery consistently produces the most significant and rapid NAD+ restoration of any available approach.

How It Works

From cellular depletion to restored clarity and energy.

01
🗓️
Consultation & Lab Review

We discuss your primary symptoms — fatigue pattern, cognitive concerns, and what you've already tried. Prior lab results or our own panel helps confirm NAD+ deficiency is the primary driver.

02
💉
IV Infusion (2–4 hours)

NAD+ is infused slowly — typically 250–500mg over 2–4 hours per session. For brain restoration and energy goals: 1–3 sessions. For addiction recovery: a course of 4–14 consecutive days as clinically indicated. Many patients notice cognitive improvement during the infusion itself.

03
📆
Maintenance Protocol

Initial series of 2–3 sessions over 2 weeks for significant depletion. Maintenance monthly to quarterly depending on your goals and response. Protocol adjusted based on how you feel and how long effects are sustained.

04
🔁
Combination Strategy

NAD IV is often combined with Myers Cocktail or B12 injections as part of a broader energy protocol. For patients addressing both cognitive and physical fatigue simultaneously, combination sessions produce more comprehensive results.

Why Choose Us

Medicine that
gets you.

NAD IV is one of the most significant interventions we offer — and requires clinical oversight to administer safely and effectively.

01

Slow Infusion Protocol

NAD+ infused too quickly causes significant discomfort — chest pressure, nausea, muscle cramping. We administer at a rate calibrated for tolerance, typically 2–4 hours. Rushing this treatment is a clinical error.

02

Clinical Setting Only

NAD IV requires IV access, rate monitoring, and clinical oversight throughout. We don't administer it as a drop-in. Every session is physician-supervised.

03

Dose Based on Goals

Maintenance doses for general wellness differ from therapeutic doses for significant cognitive or fatigue complaints. We match the protocol to your specific situation rather than using a standard dose for everyone.

04

Combination with BHRT

For patients with hormonal deficiency alongside cellular energy depletion, NAD IV and BHRT address different mechanisms and work synergistically. We assess and treat both dimensions simultaneously.

Common Questions

Everything you
want to know.

Most patients experience a mild warmth or tingling sensation as the infusion progresses. Some feel a slight chest pressure or tightness — this is common and resolves when the infusion rate is slowed. Nausea or muscle cramps can occur if the rate is too fast, which is why we infuse slowly. By the second half of the session, many patients report increased mental clarity and a sense of energy. After the session, most feel notably better than before — with effects deepening over the following 24–48 hours.
Most patients notice effects for 2–4 weeks after a single session. With a series of 2–3 sessions, many find effects lasting 4–8 weeks. Monthly maintenance sessions sustain the elevated NAD+ baseline. Patients who combine NAD IV with lifestyle factors that support NAD+ (exercise, intermittent fasting, adequate sleep) often find effects last longer between sessions.
NAD+ administered too quickly causes significant discomfort — chest tightness, nausea, and muscle cramps are common side effects of rapid infusion. Slow administration allows cells to absorb NAD+ progressively without these reactions. We calibrate the rate to your individual tolerance — some patients tolerate faster rates after their first session, others prefer to keep the rate conservative throughout.
Oral NAD+ precursors (NMN, NR) produce a modest, gradual increase in cellular NAD+ levels with consistent daily supplementation over weeks. IV NAD+ achieves therapeutic plasma concentrations immediately — at magnitudes that are physiologically impossible orally. Both have a role: oral precursors for ongoing maintenance between IV sessions; IV for significant therapeutic goals or rapid restoration.
Yes — with proper protocol. The main risks are infusion-rate-related discomfort (managed by slow administration), and very rarely, flushing or orthostatic hypotension. We monitor every session clinically. NAD+ itself is a naturally occurring molecule — there are no toxicity concerns at the doses used therapeutically.
Yes — it is one of the established clinical applications. Alcohol and substance abuse severely deplete NAD+ and disrupt neurotransmitter balance, making recovery harder. NAD IV therapy replenishes natural reserves, eases withdrawal symptoms, helps eliminate residual substances from the body, and restores normal cell functioning. A typical addiction recovery protocol runs 4–14 consecutive days. It is not a standalone cure, but it is significantly more targeted than oral medications for the neurological component of recovery.
NAD+ directly supports serotonin production — it is a cofactor in the synthesis pathway of the neurotransmitter most central to mood. Depression and anxiety linked to serotonin deficiency can worsen when NAD+ is depleted. Unlike antidepressants — which modulate receptor sensitivity but don't address underlying NAD+ deficiency — NAD IV supports natural serotonin synthesis. For patients whose mood symptoms have a neurological depletion component, it can be meaningfully effective as part of a broader treatment approach.
