Quick Answer

What Are NAD Injections?

Direct Answer

NAD injections deliver nicotinamide adenine dinucleotide — a coenzyme found in every living cell — directly into the body, bypassing the gut for higher absorption than oral supplements. Methods include subcutaneous (SubQ) injection under the skin, intramuscular (IM) injection into muscle, and intravenous (IV) infusion into the bloodstream. TrufaMED’s primary delivery is IV (100% bioavailability), with physician-prescribed SubQ available for ongoing maintenance between IV loading sessions.

The Science

What Is NAD+? The Coenzyme Behind Cellular Energy

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in every cell of the human body. It sits at the center of energy metabolism, shuttling electrons between molecules during the process of converting nutrients into ATP — the currency of cellular energy. Without adequate NAD+, mitochondria cannot produce energy efficiently, and cells begin to dysfunction.

Beyond energy production, NAD+ activates a family of proteins called sirtuins — sometimes called longevity enzymes. Sirtuins regulate gene expression, coordinate DNA damage repair, suppress inflammation, and govern cellular stress responses. They require NAD+ as a co-substrate; when NAD+ declines, sirtuin activity falls proportionally.

A third major pathway involves PARP enzymes (poly ADP-ribose polymerases), which use NAD+ to detect and repair breaks in DNA strands. PARP activity consumes NAD+ rapidly after DNA damage — which is one reason why chronic inflammation, ultraviolet exposure, alcohol, and aging itself accelerate NAD+ depletion.

NAD+ declines with age. Research published in Cell Metabolism documents that NAD+ levels in human tissue fall by approximately 50% between age 40 and 60. This decline correlates with reduced mitochondrial function, impaired DNA repair, metabolic slowdown, and increased vulnerability to age-related conditions. NAD+ injection therapy is a direct intervention to replenish what aging, lifestyle, and chronic stress remove.

Oral precursors such as NMN and NR can raise NAD+ modestly, but gut absorption varies widely by individual, supplement form, and microbiome composition. Injection bypasses this entirely, delivering the molecule at therapeutic concentrations.

Delivery Methods

Three Ways to Receive a NAD Injection

Not all NAD+ injections are the same. The route of administration determines how fast the molecule reaches circulation, how much of the dose your body uses, and what the experience feels like. Here is a clinical breakdown of each method.

SubQ • Maintenance

Subcutaneous (SubQ) Injection

A NAD+ subcutaneous injection is administered into the fatty tissue just beneath the skin — typically the abdomen or outer thigh — using a fine-gauge needle. The molecule diffuses slowly into surrounding capillaries and reaches systemic circulation over 1–4 hours.

Absorption: Slow, sustained release

Bioavailability: 70–85% (individual variation)

Onset: Effects typically perceived over days of consistent use

Typical dose: 25–100 mg per injection

Frequency: Daily to 3× weekly

Comfort: Minimal discomfort; fine-gauge needle

Ideal use: Maintenance between IV loading sessions; patients who cannot schedule regular clinic visits

Requires: Physician prescription and oversight

IM • Moderate

Intramuscular (IM) Injection

An intramuscular NAD+ injection delivers the molecule directly into muscle tissue — most commonly the deltoid or gluteus — using a standard gauge needle. Muscles have a denser capillary network than subcutaneous fat, producing faster absorption than SubQ.

Absorption: Moderate; faster than SubQ

Bioavailability: 80–90% estimated

Onset: Hours to days depending on dose

Typical dose: 50–200 mg per injection

Frequency: Weekly to bi-weekly

Comfort: Mild injection-site soreness is common

Ideal use: Patients who prefer less frequent dosing than daily SubQ but cannot access IV infusion

Requires: Clinical administration or physician oversight

IV • Full Dose

Intravenous (IV) Infusion

Intravenous NAD+ therapy delivers a high-dose solution directly into the bloodstream via an IV line. This is the most intensive and clinically validated route of administration, achieving 100% bioavailability. TrufaMED offers this as the primary NAD+ delivery method — in clinic and via mobile visit.

Absorption: Immediate; 100% bioavailability

Bioavailability: 100%

Onset: During infusion; systemic effects often reported same day

Typical dose: 500 mg (TrufaMED standard)

Duration: 2–4 hours per session

Frequency: Monthly or as part of loading protocol

Comfort: Possible flushing, chest pressure, or nausea — dose-rate dependent

Ideal use: Loading dose protocol; acute fatigue, post-viral recovery, high-performance optimization

  • Muscle soreness at injection site is common
  • Less studied than IV for NAD+ specifically
  • Requires clinical administration for higher doses
  • Mid-range option — rarely the first choice
How It Works

How NAD+ Works at the Cellular Level

Mitochondrial energy production: Inside every mitochondrion, NAD+ accepts electrons from glucose and fat metabolism, becoming NADH. NADH feeds those electrons into the electron transport chain, driving the production of ATP. When NAD+ is depleted, the chain slows. Cells produce less energy, and the person experiences fatigue, cognitive fog, and reduced physical performance.

Sirtuin pathway activation: The seven sirtuin enzymes (SIRT1–SIRT7) are among the most studied longevity regulators in human biology. They deacetylate proteins and histones, altering gene expression in ways associated with extended lifespan in animal models, reduced inflammation, and improved metabolic function. Each sirtuin reaction consumes one NAD+ molecule. When NAD+ is restored through injection or infusion, sirtuin activity rises accordingly.

DNA repair via PARP enzymes: PARP1 — the primary DNA repair enzyme — scans chromatin for strand breaks and uses NAD+ to build chains of ADP-ribose that recruit repair proteins. Chronic stress, poor sleep, alcohol consumption, and environmental toxins all generate DNA damage requiring PARP activity. This PARP consumption accelerates NAD+ depletion in a vicious cycle. Replenishing NAD+ breaks that cycle and restores repair capacity.

CD38 and the aging NAD+ drain: CD38 is a cell-surface enzyme that rises with chronic inflammation and aging. It consumes NAD+ as a signaling molecule — and unlike PARP, it does not produce useful repair. High CD38 activity is one of the primary drivers of age-related NAD+ decline. Therapeutic NAD+ replenishment helps offset this drain, though it does not eliminate the underlying inflammatory driver.

What this means clinically: A single IV NAD+ session floods the bloodstream with substrate the body’s repair and energy systems can immediately use. Most patients report heightened mental clarity, improved sleep, and reduced fatigue in the days following infusion. These effects are not placebo — they reflect genuine metabolic normalization in cells that were substrate-limited.

What to Expect

Side Effects of NAD+ Therapy

Most side effects of NAD+ injection therapy are dose-rate dependent and transient. IV infusion carries the widest range of sensations because the molecule reaches circulation rapidly. SubQ and IM injections are generally better tolerated but produce milder effects overall. All side effects below are manageable under physician supervision.

Flushing
Warmth or redness in the face, neck, and chest during IV infusion. Common, harmless, and resolves by slowing the infusion rate.
Chest Fluttering
A pressure or fluttering sensation in the chest, sometimes described as palpitations. Dose-rate dependent — slowing the drip resolves it in most cases. Physician monitoring is standard at TrufaMED.
Nausea
Mild stomach discomfort, particularly at higher doses or faster infusion rates. Pre-hydration and rate management reduce incidence significantly.
Post-Session Fatigue
Some patients feel tired the evening after a high-dose IV session. This appears to reflect cellular activity — most report significantly improved energy beginning the following morning.
Injection-Site Reactions
Mild redness, bruising, or swelling at the SubQ or IM site. Rotation of injection sites and proper technique minimize this. Rare with IV.
Stomach Discomfort
Some patients notice GI sensitivity at higher doses. Most resolve within a few hours. Eating before an IV session and slower drip rates reduce incidence.
Headache
Mild headache, more common with dehydration before the session. Concurrent saline hydration at TrufaMED sessions reduces this significantly.
Transient Muscle Cramps
Occasional and brief. Associated with rapid changes in cellular electrolyte balance during high-dose infusion. Uncommon at standard TrufaMED dosing.

All TrufaMED NAD+ IV sessions are administered by or under the direct supervision of a licensed physician. Infusion rate is adjusted in real time based on patient response. Side effects are discussed during the pre-session consultation, and baseline labs are reviewed before initiating therapy.

TrufaMED Protocol

TrufaMED’s Approach to NAD+ Therapy

At TrufaMED, NAD+ therapy begins with IV — because bioavailability matters when the goal is therapeutic tissue saturation, not simply raising a lab marker. Our standard protocol uses a 500 mg IV dose administered over 2–4 hours at our Surfside clinic, or delivered to your location via our mobile IV service across South Florida.

Before initiating NAD+ therapy, a physician consultation is required. We review your health history, current medications, and relevant labs. Contraindications are evaluated individually. We do not administer NAD+ as a wellness vending service — every session is physician-ordered and supervised.

For patients who want to maintain elevated NAD+ levels between monthly IV sessions, we offer physician-prescribed subcutaneous NAD+ injection kits for home use. These are dispensed under physician oversight, with training on proper technique, dose, and rotation. SubQ doses are lower than IV and designed to sustain — not replicate — the loading achieved by infusion.

Patients with chronic fatigue, post-viral syndrome, or addiction recovery histories may benefit from a loading protocol — multiple IV sessions over the first 1–2 weeks — before transitioning to monthly maintenance. This is determined on a case-by-case basis during your initial consultation.

We are Joint Commission accredited — Florida’s only accredited urgent care — and our physician team includes board-certified physicians in emergency medicine and general surgery. NAD+ therapy is ordered and supervised by Dr. Shane D. Naidoo (Medical Director, Board-Certified Emergency Medicine) and Dr. Uri Gedalia (CMO, Board-Certified General Surgery).

Patient Profiles

Who Benefits from NAD+ Injections

NAD+ injection therapy is not a universal fix — it is a targeted biochemical intervention most relevant to people whose NAD+ levels are meaningfully depleted or whose performance demands exceed what diet and rest can restore.

High Performers
Executives, entrepreneurs, and athletes who experience cognitive decline under sustained pressure. NAD+ restores the mitochondrial substrate that fuels high-demand mental and physical output.
Chronic Fatigue
Patients with medically unexplained fatigue or post-viral exhaustion often show improved energy and reduced brain fog following a NAD+ IV loading series. Physician evaluation required first.
Post-Viral Recovery
Emerging research links post-viral syndromes to mitochondrial dysfunction and elevated CD38-driven NAD+ depletion. IV NAD+ is increasingly used as part of supervised recovery protocols.
Longevity-Focused Adults
Individuals 40+ who prioritize healthspan optimization and are tracking NAD+ as a longevity biomarker. Monthly IV plus SubQ maintenance is the standard protocol for this group.
Addiction Recovery
High-dose IV NAD+ has been used in physician-supervised addiction recovery settings to reduce withdrawal intensity and restore neurological function. This use requires careful clinical oversight.
Athletes in Training
Competitive athletes benefit from faster cellular repair, reduced oxidative stress, and improved mitochondrial efficiency. NAD+ IV fits naturally into recovery-week programming alongside HBOT.
Metabolic Optimization
Patients managing metabolic health concerns under physician care often incorporate NAD+ therapy as an adjunct to support mitochondrial function and insulin sensitivity at the cellular level.
Pre / Post Travel
Frequent transatlantic travelers and professionals with demanding schedules use NAD+ IV to recover from jet lag and extended stress. Our mobile service delivers to hotels across Miami Beach.
Clinical Safety

Safety, Contraindications, and Physician Oversight

NAD+ injection therapy has a favorable safety profile when administered by trained clinicians at appropriate doses and rates. The risks rise significantly in unmonitored settings — medspa administration without physician involvement, self-injection without training, or online-purchased vials of unknown purity. TrufaMED does not practice any of these.

What We Review Before Your First Session

  • Complete health history and current medications
  • Baseline metabolic labs (kidney and liver function)
  • Cardiovascular history (relevant to infusion rate tolerance)
  • Current supplements and NAD+ precursors (NMN, NR)
  • Pregnancy status — NAD+ IV is not recommended during pregnancy
  • Active cancer diagnosis — defer to oncologist before IV NAD+
  • History of seizure disorders — individual assessment required
  • Blood pressure and resting heart rate at time of session

Why Physician Oversight Matters

  • Infusion rate determines side effect intensity — physician adjusts in real time
  • Drug interactions with certain psychiatric medications require awareness
  • Compounded NAD+ vials vary in purity — we use pharmaceutical-grade supply only
  • High-dose IV is not equivalent to oral supplementation — escalation requires clinical logic
  • SubQ injection technique affects absorption uniformity and site health
  • Allergic reactions, while rare, require immediate medical response capability
  • Patients with hemodynamic instability should not receive IV NAD+
  • Joint Commission accreditation means our protocols are third-party verified

Questions & Answers

Frequently Asked Questions

What is the difference between a NAD injection and NAD+ IV therapy?

The terms are often used interchangeably but describe different delivery routes. A NAD injection refers to subcutaneous (SubQ) or intramuscular (IM) administration using a syringe — doses are lower (25–200 mg) and absorption is gradual. NAD+ IV therapy delivers a larger dose (typically 500 mg) directly into a vein over 2–4 hours, achieving 100% bioavailability and immediate systemic effect. TrufaMED uses IV as the primary therapeutic route, with SubQ available as physician-prescribed maintenance.

Can I inject NAD+ at home?

SubQ NAD+ injection can be self-administered at home — but only under physician supervision, with proper training, using pharmaceutical-grade compounded vials, and with a valid prescription. Online vendors selling NAD+ vials without physician involvement should be avoided. Purity, concentration, and sterility cannot be verified without clinical oversight. At TrufaMED, we prescribe SubQ maintenance kits and provide training to qualified patients following their initial IV session and consultation.

How often should I get a NAD injection or IV?

Frequency depends on your goals, current NAD+ status, and clinical history. A common loading protocol for new patients involves 2–4 IV sessions over the first month, then monthly maintenance. Patients using SubQ between IV sessions typically inject daily to 3 times per week at lower doses. There is no single correct frequency — this is determined during your physician consultation based on your individual needs and response to initial sessions.

How much does a NAD shot or IV session cost in Miami?

At TrufaMED, NAD+ IV therapy is $999 per session at our Surfside clinic, or $1,250 for mobile delivery to your home, hotel, or office across South Florida. Physician-prescribed SubQ maintenance kits are separately priced at approximately $150–$300 per supply cycle depending on dose and duration. All sessions include a pre-treatment physician or clinical review. There are no hidden fees.

What does a NAD injection feel like?

SubQ and IM injections are similar to any standard shot — a brief pinch with minimal discomfort. IV infusion is different: as the NAD+ enters your bloodstream, you may notice warmth in the face and chest, a mild fluttering sensation, or a feeling of pressure. These sensations are dose-rate dependent and resolve by slowing the infusion. Most patients find the experience manageable, particularly after the first session when they know what to expect. TrufaMED clinicians adjust your rate in real time.

Is NAD+ injection therapy covered by insurance?

NAD+ injection therapy and IV infusion are not covered by standard health insurance plans for general wellness or optimization purposes. In certain clinical contexts — such as addiction recovery under medical supervision — partial reimbursement may be possible depending on the plan. TrufaMED accepts self-pay and can provide documentation for HSA/FSA reimbursement in applicable cases. We recommend contacting your insurance directly to clarify your specific plan’s position on IV nutrient therapy.

What is the difference between a medspa NAD+ injection and a physician-supervised one?

The core difference is clinical oversight. A physician-supervised NAD+ session includes a health review, labs if indicated, contraindication screening, real-time infusion rate management, and the ability to respond medically if an adverse reaction occurs. Medspa settings often administer NAD+ IV under a blanket medical director protocol with no physician physically present — and may not screen for drug interactions or contraindications. TrufaMED operates as a Joint Commission-accredited medical facility, not a wellness spa. A physician is involved in every session.

How long does it take to feel the effects of a NAD injection?

With IV infusion, many patients notice increased mental clarity and energy during or immediately after the session. Peak cellular effects — improved sleep, sustained energy, reduced fatigue — are typically felt over the 24–72 hours following infusion. SubQ injections work more gradually: most patients notice cumulative improvement over 1–3 weeks of consistent daily use. Effects vary by individual, baseline NAD+ levels, sleep quality, and lifestyle factors during the therapy period.

Are there any contraindications to NAD+ injection therapy?

Yes. NAD+ IV is not recommended during pregnancy. Patients with active cancer should defer to their oncologist before initiating NAD+ therapy, as elevated NAD+ theoretically supports cell proliferation. Individuals with certain cardiac arrhythmias, hemodynamic instability, or severe kidney or liver dysfunction require individual physician assessment before proceeding. Certain psychiatric medications (particularly MAOIs) may interact. A physician review at TrufaMED addresses all of these before your first session.

Can I combine NAD+ injection therapy with HBOT or other IV drips?

Yes — NAD+ IV and HBOT are increasingly used together in longevity and performance protocols. HBOT increases oxygen delivery to mitochondria; NAD+ provides the cofactor those mitochondria need to produce ATP efficiently. The combination is synergistic and safe under physician supervision. NAD+ can also be combined with standard IV hydration or vitamin drips on separate days. Same-session stacking (NAD+ IV plus another IV simultaneously) is evaluated case-by-case. Contact our team to discuss a combined protocol.

How does NAD+ injection therapy compare to taking NMN or NR supplements?

NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are oral NAD+ precursors — the body converts them into NAD+ after absorption. Their advantages are convenience and cost. Their limitations are gut absorption variability, first-pass metabolism, and the dose ceiling of what can be practically swallowed. IV NAD+ bypasses all of these: it delivers the final molecule directly at 100% bioavailability in a single session dose that would be impossible to achieve orally. Many patients use oral precursors daily and IV infusion monthly as a tiered strategy.

Is NAD+ the same as vitamin B3?

Related, but not identical. Niacin (vitamin B3) and its derivatives — nicotinamide and nicotinic acid — are the dietary precursors from which the body synthesizes NAD+. Taking large doses of niacin can raise NAD+ levels, but with well-known side effects including intense flushing. NAD+ injection therapy delivers the end-molecule directly, bypassing the multi-step biosynthesis pathway and avoiding the side-effect profile of high-dose niacin supplementation. They share metabolic ancestry but are clinically distinct interventions.
