NAD+ IV therapy delivers nicotinamide adenine dinucleotide, a coenzyme every cell uses to make energy, directly into a vein over two to four hours. At Venturis Clinic in Oklahoma City it is offered only after a Good Faith Exam, and we are honest that the lab science is strong while the human evidence for IV NAD+ is still thin.
This page covers what NAD+ is, what a session actually involves, including the part most clinics do not mention, who it may suit, who should not have it, and what the research does and does not support.
Important information
NAD+ intravenous therapy is not approved by the U.S. Food and Drug Administration for the treatment or prevention of any disease. Nothing on this page is a claim of efficacy, and no outcome is promised or implied. Individual results vary. This page is for general education and is not medical advice. NAD+ therapy is offered only after individual evaluation, is not appropriate for everyone, and is not a substitute for established medical care.
What NAD+ is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell in your body. It is central to how cells convert food into usable energy, and it is a required substrate for several repair enzymes, including the sirtuins and PARPs involved in DNA repair and cellular maintenance.
NAD+ levels decline with age. That is well documented in laboratory research, and in animal models restoring NAD+ produces measurable improvements in mitochondrial function and markers associated with aging. This is real science from serious laboratories, and it is why the topic gets the attention it does.
The open question, the one the marketing skips, is whether infusing NAD+ intravenously in humans produces meaningful clinical benefit. That has not been established, and we come back to it below.
How NAD+ IV therapy works
When you take NAD+ precursors by mouth, they are broken down and absorbed in the gut before your body converts them. An IV delivers NAD+ straight into the bloodstream, which bypasses digestion. A pharmacokinetic study has shown that IV NAD+ does reach the blood and is metabolized. That tells us it gets in; it does not tell us it produces a benefit you would notice.
NAD+ is mixed into a bag of IV fluid and dripped slowly. The rate matters more than with almost any other infusion, because NAD+ given too fast causes uncomfortable symptoms.
What a session actually involves
This is the part most clinics underplay, and you should know it before you book.
NAD+ infusions are slow, and they are not always comfortable. Infused too quickly, NAD+ commonly produces chest tightness, abdominal cramping, nausea, flushing and a general sense of unease. It is not dangerous, but it is unpleasant, and the way to manage it is to slow the drip down.
That means a full NAD+ infusion typically takes two to four hours, sometimes longer for a first session.
- Good Faith Exam first. Licensed medical staff review your history, current medications and, in most cases, recent labs before any infusion.
- Slow start. We begin at a low rate and increase only as you tolerate it.
- You tell us how you feel. The rate is adjusted throughout based on your symptoms. This is a collaborative infusion, not a set-and-forget one.
- Monitoring. Infusions are performed by licensed medical staff under our medical director, who supervise you throughout.
- Afterward. Most people feel fine and go about their day. Some feel tired.
Bring something to do. You will be there a while.
Who may suit NAD+ IV therapy
People come to us about NAD+ for long-lasting fatigue, brain fog and cognitive complaints, post-viral illness including long COVID, recovery from prolonged stress or burnout, and general healthy-aging interest.
Whether NAD+ is the right answer for any of those depends on what is actually driving the fatigue, and fatigue has a long list of causes worth ruling out first, including thyroid problems, anemia, sleep apnea, mold and biotoxin illness, Epstein-Barr reactivation and depression. An expensive infusion for undiagnosed sleep apnea helps nobody. Our lab testing page explains how we look for those causes.
Who should not have NAD+ IV therapy
NAD+ IV therapy may not be appropriate, or needs extra caution, if you:
- Are pregnant or breastfeeding
- Have significant heart disease, uncontrolled blood pressure or a history of chest pain
- Have kidney or liver disease that affects how you clear fluids and medications
- Cannot sit for several hours or have very difficult IV access
- Take medications that need review before an infusion
These are discussed at your Good Faith Exam. If NAD+ is not a good fit, we will say so and talk about other options, including oral precursors.
Safety and risks
Where the formula comes from. Our IV formulas are prepared by an FDA-registered 503B outsourcing facility under current Good Manufacturing Practice (cGMP) standards and tested for sterility and potency before release. Each infusion is ordered after your Good Faith Examination and given by our nurses. Compounded IV formulas are not FDA-approved to diagnose, treat, cure or prevent any disease. See our full IV menu.
The most common problem is discomfort during the infusion when the rate is too fast: chest tightness, cramping, nausea and flushing. These usually settle within minutes when the drip is slowed. Like any IV, there is a small risk of bruising, irritation of the vein or, rarely, infection at the site. Some people feel tired or “wired” later that day. Serious reactions are uncommon, and you are monitored throughout so the infusion can be slowed or stopped.
What the research currently shows
We want to be direct, because there is a great deal of confident marketing around NAD+.
The preclinical evidence is strong and interesting. NAD+ decline with age is well documented, and in animal models restoring NAD+ improves mitochondrial function, metabolic markers and several measures associated with aging.
The human evidence is much more limited. Most clinical research to date has used oral NAD+ precursors, nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN), rather than intravenous NAD+. Those trials generally show that blood NAD+ levels can be raised safely, but results on clinical outcomes such as energy, cognition and physical function have been modest and inconsistent. Trials of intravenous NAD+ specifically are few and small.
NAD+ IV therapy is not FDA-approved for any condition. If a clinic tells you NAD+ will reverse aging, repair your DNA, or resolve chronic fatigue, they are describing something the evidence does not currently establish. We are not going to tell you that. What we will do is look for the treatable causes of your fatigue first, be honest about where NAD+ sits in the evidence, and tell you when something else would serve you better.
Cost and practical details
Cost. NAD+ is one of the more expensive infusions we offer, largely because of how long a session takes. Cost is discussed at your consult, before anything is scheduled.

Frequently asked questions
Is there NAD+ IV therapy near me in Oklahoma City?
Yes. Venturis Clinic offers NAD+ infusions at 7917 N. May Ave, Oklahoma City, OK 73120, serving the OKC metro including Edmond, Nichols Hills, Norman and Moore. Call (405) 848-7246.
How long does an NAD+ infusion take?
Typically two to four hours, sometimes longer for a first session. NAD+ has to be infused slowly to be tolerable.
Does NAD+ IV therapy feel unpleasant?
It can if infused too quickly. Chest tightness, cramping, nausea and flushing are common at higher rates. This is managed by slowing the infusion, and we adjust throughout based on how you feel.
Is NAD+ IV therapy FDA-approved?
No. NAD+ IV therapy is not approved by the FDA for the treatment of any condition.
How many sessions would I need?
There is no established protocol, and we are not going to invent one. It is discussed after your Good Faith Exam, as part of a broader plan.
Is IV NAD+ better than oral NR or NMN?
Most human research has used oral precursors like NR and NMN, which cost far less. IV delivery bypasses absorption, but that has not been shown to translate into better outcomes. For many people, starting oral is the more sensible first step, and we will say so.
NAD+ therapy in Oklahoma City
Almost everyone who calls us about NAD+ is tired. Not ordinary tired, but the kind that has lasted months or years, does not improve with sleep, and has usually been dismissed at least once.
The most useful thing we do is rarely the infusion. It is the part before it: working out what is actually causing the fatigue. Sometimes that is thyroid, or iron, or sleep apnea, or a post-viral process, or mold exposure in a building, or Epstein-Barr reactivation. Those have specific answers, and an NAD+ drip is not any of them.
Where NAD+ does fit, it fits as one part of a broader plan, sometimes alongside IV nutrient support, laser therapy, hyperbaric oxygen or ozone-based therapies, and always after the treatable causes have been looked for.
