Before You Consider an Infusion
NAD+ infusions have attracted interest among people exploring wellness and healthy aging. NAD+ has important roles in cellular processes, but that biology does not establish that an infusion improves energy, slows aging, or produces other lasting health benefits. A recent systematic review found that evidence for anti-aging and wellness outcomes remains inconclusive, and it identified no eligible clinical outcomes trials of NAD+ infusions for those purposes review of NAD⁺ supplementation.
This guide separates what is known about NAD+ from what remains uncertain. It explains what an infusion involves, reviews possible risks and product-safety questions, and offers practical points to discuss with a clinician before booking. At janahealthcare.com, NAD+ infusions are offered within a multidisciplinary medical practice in Brooklyn, where a clinician can consider a patient’s goals and health history.
The information here is general, not an individualized treatment recommendation or a substitute for established medical care. A consultation can help determine whether an infusion is appropriate, whether other causes of symptoms need attention, and what expectations are realistic.
NAD+ and Its Role in Cells
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. It helps transfer electrons during chemical reactions that turn nutrients into usable energy, including processes in the mitochondria. For a broader overview of this cellular role, see NAD+ and cellular energy.
NAD+ also contributes to DNA repair and cellular signaling, and it helps regulate proteins such as sirtuins, which take part in cellular stress responses. These functions explain why researchers study NAD+ biology, but they do not show that an infusion repairs DNA, prevents disease, or slows aging.
The body continually makes and uses NAD+. Levels may vary with age, tissue, and health, but a general pattern of age-related change cannot diagnose an individual or establish that raising NAD+ will reverse aging. A 2026 systematic review found that human research on NAD-related interventions has mainly examined oral precursors, with mixed results for health outcomes; it identified no eligible clinical outcomes trials of intravenous NAD+ for anti-aging or wellness (review of NAD+ supplementation research).
NAD+ infusions are not the same as oral nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN). The body can use these precursors to make NAD+, but findings about oral supplements do not establish the effects of infusing NAD+ itself. Jana HealthCare is a multidisciplinary Brooklyn practice, so discussions about wellness therapies can be considered alongside a person's broader clinical and aesthetic care, with expectations grounded in the limits of current evidence.
What Research Can and Cannot Show
A 2026 systematic review examined 113 intervention studies, including 33 in humans. Most human studies focused on oral nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), or related compounds, rather than NAD+ infusions or injections. The review’s findings therefore cannot be treated as direct evidence for infused NAD+ the 2026 systematic review.
Oral NR and NMN can raise NAD-related biomarkers, but a change in a blood or cellular marker does not by itself show a meaningful improvement in how someone feels or functions. Across the studies, results for wellness and health outcomes were mixed, often null, or limited to particular measures or groups.
The review found no eligible clinical outcomes trials testing IV, intramuscular, or subcutaneous NAD+ itself for anti-aging or wellness. Small early studies may offer information about short-term tolerability or biomarkers, but they cannot establish lasting benefits. This distinction matters when weighing claims about infusions against the broader evidence on NAD biology, as discussed in research on NAD+ therapy.
Claims that an NAD+ infusion will reliably increase energy, sharpen thinking, improve mood, reduce fatigue, or extend longevity remain unproven. Individual reports can be meaningful to the person describing them, but they are not a substitute for controlled research that can separate treatment effects from expectation or other factors.
At Jana HealthCare, a multidisciplinary Brooklyn practice offering clinical care alongside wellness services, discussion of an infusion can take place in the context of a person’s health history and goals rather than as a guaranteed result. NAD+ therapy should not replace adequate sleep, exercise, a healthy diet, evaluation of treatable symptoms, or other care with established benefits. A clinician can help weigh the limited evidence, possible discomfort and individual risks, and whether the approach fits alongside that care.
What an Infusion May Feel Like
A clinician places an IV catheter, which may cause a brief pinch, then administers the solution while you rest in a chair. The treatment team should monitor how you feel and respond if symptoms arise. For a closer look at the general process, see what to expect during an IV infusion.
There is no single standard session length. The time depends on factors such as the dose, infusion rate, your tolerance, and the clinic’s protocol. NAD+ infusion reports describe sessions ranging from roughly one to four hours, with some lasting longer, so ask the clinician what to expect for the proposed plan.
Some people report warmth or flushing, nausea, stomach cramping, headache, dizziness, chest tightness or pressure, or changes in heart rate or blood pressure. These sensations are not inevitable, and individual experiences vary. A 2026 systematic review found no eligible clinical outcomes trials of IV NAD+ for anti-aging or wellness, so reports should not be mistaken for a predictable response.
Discomfort may be related to the dose or how quickly the infusion runs. Tell the clinician promptly about any symptoms, particularly chest pressure, rather than trying to endure them. The clinician may assess you, slow or pause the infusion, or stop treatment.
Some symptoms call for urgent medical attention rather than an infusion adjustment. Seek help for trouble breathing, swelling of the face or throat, hives, chest pain, a racing heartbeat, or loss of consciousness. At janahealthcare.com, NAD+ infusions are offered in a Brooklyn medical practice, where an individualized discussion can include the planned treatment and how you will be monitored.
Possible Side Effects and Product Safety
Side effects vary by product and route, so oral precursors, injections, and IV infusions should not be treated as interchangeable. Oral nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) may cause digestive symptoms. Injections may cause nausea, flushing or warmth, headache, fatigue, dizziness, or soreness, redness, and bruising at the injection site.
An IV infusion can also cause chest tightness or changes in heart rate or blood pressure, particularly if it runs quickly. Seek urgent medical care for trouble breathing, facial or throat swelling, hives, chest pain, or a racing heartbeat. Tell a healthcare professional about symptoms that persist or feel concerning. Jana HealthCare's multidisciplinary care includes clinical services alongside aesthetic and wellness therapies, making an individualized discussion of medical history and treatment concerns a sensible first step.
Long-term safety data for injectable NAD+ remain limited. This gap does not show that treatment is either safe or harmful over the long term. Compounded injectable products are not FDA-approved finished drugs for a specific medical indication, and they do not undergo the same premarket review for safety, efficacy, and quality as approved drugs.
Sterile preparation and product sourcing matter because an injection enters the body directly. Ingredients intended for food or oral supplements are not appropriate for sterile injection. Contamination, including bacterial endotoxins, can cause serious reactions. Before treatment, ask which pharmacy supplied the product, whether its ingredients are suitable for sterile use, and what sterility or endotoxin testing is available.
Also ask who will administer and supervise the infusion and how the clinical team responds to adverse reactions. These questions support informed decision-making; they are not a guarantee that a product or provider is safe. For a broader comparison of route-specific concerns, see possible side effects of NAD+ therapy.
Who Should Seek Individual Guidance
Before considering NAD+ therapy, review your health history, current symptoms, medications, supplements, allergies, goals, and expectations with a qualified healthcare professional. At janahealthcare.com, a multidisciplinary Brooklyn practice, this kind of discussion can help place a wellness treatment in the context of a person’s broader medical and aesthetic care.
Individual assessment is especially important for people with chronic conditions, complex medication regimens, immune compromise, or other ongoing treatments. Anyone with active cancer or a history of cancer should discuss the question with their treating clinician, including an oncologist where appropriate, before proceeding. NAD+ biology is under study, and it does not establish that an infusion is appropriate for every health situation.
Safety during pregnancy and breastfeeding has not been established, so people who are pregnant, planning pregnancy, or breastfeeding should speak with a healthcare professional before considering treatment. Allergies also deserve specific attention: ask the provider to review the actual product formulation if you have a known allergy to an ingredient, such as benzyl alcohol when it is present.
There is not enough evidence to define a universal list of medications that must never be combined with NAD+ therapy. Possible risks can depend on the product, a person’s health, and the full treatment plan. Bring an up-to-date medication and supplement list, and do not start, stop, or change a prescribed medication without professional advice. For more on individualized safety considerations, see guidance on NAD+ therapy side effects.
Depending on the circumstances, a clinician may consider examination findings or laboratory tests when discussing treatment. Tests can help assess aspects of health, but they do not predict whether NAD+ will work or automatically determine eligibility. At janahealthcare.com, decisions about wellness therapies should be considered alongside a person’s medical history and goals, rather than based on a single test result.
Choosing a Schedule With a Clinician
There is no universal NAD+ infusion dose, frequency, or treatment duration established by strong clinical evidence. Some clinics offer weekly sessions or loading schedules, but these are practice protocols, not proven standards for every patient. A 2026 systematic review found no eligible clinical outcomes trials of intravenous NAD+ for anti-aging or wellness, underscoring how much remains uncertain about treatment plans and results (systematic review of NAD+ interventions.
A licensed clinician should decide whether to proceed and, if appropriate, recommend a dose and schedule after reviewing your medical history, medications, goals, prior reactions, and relevant examination findings or test results. At Jana HealthCare, NAD+ infusions are offered within a multidisciplinary medical practice, where an individual discussion can help place the therapy in the context of a person's broader health needs.
Before starting, agree on what would count as a meaningful outcome and when you will review it. Reassess whether treatment is helping and remains appropriate rather than assuming recurring infusions are necessary or effective. If the intended benefit is absent, symptoms worsen, or the burden outweighs any perceived value, discuss stopping or reconsidering the plan.
Questions to ask before booking
Ask what evidence supports the intended goal, how long the appointment will take, and what the full cost will be. Confirm who will monitor the infusion, what product will be used, and where it is compounded. Discuss risks specific to your health, as well as alternatives, including not proceeding. Jana HealthCare's Brooklyn practice combines clinical care with wellness services, making it reasonable to ask how an infusion fits alongside other care options.
NAD+ infusions are not FDA-approved for a specific medical indication. Compounded preparations are not reviewed by the FDA for safety, effectiveness, or quality before distribution. This regulatory distinction does not by itself prove a product is unsafe, but it makes clear discussion of sourcing, oversight, evidence, and uncertainty especially important.
Skin Claims Need Careful Perspective
NAD+ participates in cellular energy use and repair, but that biological role does not establish that supplements or infusions improve skin appearance or tighten loose skin. A 2026 systematic review of NAD⁺ supplementation found human evidence for dermatologic and aesthetic-aging outcomes to be sparse, with no eligible trials of IV or injected NAD⁺ for skin-aging outcomes.
Can NAD+ therapy improve skin appearance or sagging skin? Current research has not established it as a skin-tightening treatment. Loose skin can have different causes, and the most suitable approach depends on a person's skin, health, and goals. A dermatologist or qualified clinician can discuss options with evidence relevant to the specific concern, including skin-care treatments or procedures when appropriate.
At Jana HealthCare, cosmetic dermatology is part of a multidisciplinary Brooklyn practice, so concerns about skin can be considered alongside a person's broader health and aesthetic goals. A decision about NAD+ therapy should remain separate: discuss the uncertain cosmetic benefits, possible risks, and costs with a qualified clinician rather than treating an infusion as a substitute for care tailored to loose skin. For more context, see why skin claims need careful context.
Weight Loss Claims and Realistic Goals
NAD+ plays a role in cellular metabolism, but that biological function does not show that supplements or infusions cause weight loss. The available evidence does not establish NAD+ therapy as a way to reduce body weight or belly fat.
A change in an NAD-related blood marker would not, on its own, demonstrate a reduction in body fat or an improvement in weight-related health. A 2026 systematic review found mixed or inconclusive results for wellness outcomes and no eligible clinical outcome trials of NAD+ infusions for anti-aging or wellness claims. The review does not support treating a biomarker change as proof of weight loss.
NAD+ therapy is not a substitute for evidence-based weight-management care, and it is not equivalent to semaglutide, a medication with clinical evidence for specific indications. For readers exploring care in Brooklyn, Jana HealthCare’s multidisciplinary practice offers clinical and wellness services, where a weight-related discussion can take account of personal health needs rather than rely on an infusion as a stand-alone solution.
If weight management is your goal, discuss your health history, medications, and options with a qualified clinician. A clinician can help set realistic goals and consider approaches supported by evidence, while making clear what NAD+ therapy can and cannot be expected to do.
Make an Informed, Personal Decision
NAD+ supports important processes inside cells, but that role alone does not show that an infusion provides lasting wellness, anti-aging, skin, or weight-loss benefits. A 2026 systematic review found that evidence for wellness outcomes remains inconclusive and did not identify eligible trials of intravenous NAD+ for these outcomes review of NAD⁺ supplementation.
Before booking, consider the uncertain benefits alongside the time involved, possible discomfort, product sourcing and sterility, cost, and your own health circumstances. A qualified clinician can review your history, explain the proposed treatment and available oversight, and discuss alternatives. At Jana HealthCare, NAD+ infusions are offered within a multidisciplinary medical and aesthetic practice in Brooklyn, where the decision can be considered alongside broader care and established health habits.
