What Are NAD Infusions — and Do They Actually Work?
NAD infusions are intravenous (IV) drips that deliver nicotinamide adenine dinucleotide — a coenzyme your cells need to produce energy and repair DNA — directly into the bloodstream. Here’s a quick snapshot of what you need to know:
- What they are: IV therapy that delivers NAD+ directly into the blood, bypassing the digestive system
- Why people use them: To support energy levels, cellular repair, healthy aging, and recovery from conditions like long COVID
- Key limitation: NAD+ molecules have difficulty crossing from the bloodstream into cells, which may reduce effectiveness
- Known side effects: Nausea, abdominal cramping, and vomiting can occur during the drip
- Scientific status: Early-stage human research shows promise, but large clinical trials have not yet confirmed the benefits seen in animal studies
- Alternatives: Oral precursors (NR and NMN), complementary nutrients like thiamine and magnesium, and lifestyle changes also support NAD+ levels
The science behind NAD+ is genuinely exciting. Researchers have found that natural NAD+ levels decline as we age, and restoring them in rodents has produced remarkable results — improved energy, better DNA repair, and signs of healthier aging. In humans, though, the evidence is still catching up to the marketing. As one researcher put it, “the cart may be well ahead of the horse.”
This guide cuts through the hype to give you a clear, evidence-based picture of what NAD+ therapy can — and cannot — do.
I’m Anna Slavin, Practice Manager at Global Pain & Spine Clinic, where our multidisciplinary team has over 20 years of experience helping patients across the Northern Chicago area explore evidence-based treatments — including NAD infusions — as part of personalized recovery and wellness plans. In the sections ahead, we’ll walk you through the science, the delivery options, the safety profile, and how to decide whether NAD+ therapy is right for you.

Understanding the Science of NAD Infusions
To understand why health and wellness circles are so focused on nad infusions, we have to zoom in on what is happening inside our cells. Nicotinamide adenine dinucleotide (NAD+) is a fundamental coenzyme found in every single living cell of your body. Without it, your mitochondria—the powerhouses of your cells—cannot convert the food you eat into the cellular energy (adenosine triphosphate, or ATP) that keeps you alive and moving.
Beyond energy production, NAD+ plays a critical role in cellular maintenance. It acts as a key helper molecule for sirtuins, a family of proteins that regulate cellular aging, reduce inflammation, and repair damaged DNA.
To learn more about the basic biology of this molecule, you can read our guide on nad explained simply the science behind the name.
The Science Behind NAD Infusions
As we age, our natural levels of NAD+ gradually decline. This reduction is linked to many of the common signs of aging, including decreased physical stamina, brain fog, and slower healing. To combat this decline, researchers and clinicians have explored various ways to replenish cellular NAD+ levels.
An nad infusion delivers the coenzyme directly into your bloodstream. By using an intravenous drip, the compound bypasses your digestive system entirely. In theory, this allows for immediate availability throughout the body. However, the scientific community is actively researching exactly how much of this circulating NAD+ makes its way into your cells, where it is actually needed.
Cellular Absorption Barriers
One of the most fascinating aspects of NAD+ biology is the “cellular transport paradox.” Even though we can flood the bloodstream with NAD+ through an IV, the molecule itself is relatively large and highly charged. Because of this, it does not have an “easy door” or a direct transporter to cross the cell membrane from the bloodstream.
A pilot study of 14 people found that direct infusions of nad were highly inefficient at increasing NAD+ levels inside the cells themselves. Instead of entering the cell intact, the infused NAD+ must often be broken down by extracellular enzymes into smaller precursor molecules, which are then transported into the cell and rebuilt. This biological bottleneck is why scientists are continuing to study how the body processes direct infusions compared to other delivery methods.
The Health and Wellness Benefits of NAD+ Therapy
Despite these cellular transport questions, many individuals report experiencing positive changes after receiving intravenous NAD+ therapy. Let’s look at what the current research and clinical observations tell us about the potential benefits of nad infusion.
Who Can Benefit from NAD Infusions?
Many patients who seek out nad therapy complete guide are struggling with chronic, persistent fatigue that does not improve with rest. This includes people recovering from post-viral syndromes, such as long COVID.
In post-viral fatigue, the body’s mitochondria often enter a state of dysfunction, leaving the individual feeling constantly drained. Supplying the body with the raw materials needed to rebuild mitochondrial energy pathways can help support cellular recovery and ease that deep-seated exhaustion. If you feel like your body is constantly running on empty, you might find our article on why your cells are begging for an nad plus treatment helpful.
Chronic Pain and Physical Rehabilitation
At Global Pain & Spine Clinic, we often look at how cellular therapies can support physical rehabilitation and chronic pain management. Chronic pain is closely tied to neuroinflammation and cellular stress. When tissues are injured or inflamed over long periods, the local cells deplete their energy reserves trying to repair themselves.
By supporting cellular repair and reducing oxidative stress, NAD+ therapy can work alongside traditional physical therapy and chiropractic care to promote tissue regeneration. When combined with advanced treatments in regenerative medicine, supporting your cellular health from the inside out creates a stronger foundation for lasting recovery.
Comparing NAD+ Delivery Methods: IV, Injections, and Oral Supplements
If you are considering NAD+ therapy, you have likely noticed that it comes in several forms: intravenous drips, subcutaneous or intramuscular injections, and oral supplement pills. Choosing the right method depends on your health goals and how your body absorbs these compounds.
NAD+ Injections vs. IV Drips
For those looking for an alternative to a full IV session, injections are an increasingly popular option. You can read more about this approach in our nad injection guide boosting your cells from the inside out.
While an IV infusion delivers a steady stream of fluid over several hours, an injection is a quick, concentrated dose. To understand how they compare, consider these points:
- Absorption Rate: IV drips deliver the compound directly into the bloodstream over an extended period, allowing for a slower, sustained release.
- Convenience: Injections are much faster to administer, making them an option for busy schedules.
- Cellular Uptake: Both methods bypass the digestive tract, but they may interact with muscle tissue and local blood vessels differently.

Oral Precursors and Gut Degradation
Oral NAD+ supplements are widely available, but they face a major hurdle: the human digestive tract. When you swallow pure NAD+, the enzymes in your stomach and intestines quickly break it down, meaning very little of the active compound actually reaches your bloodstream intact.
To get around this, researchers have focused on oral precursors like Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN). These precursor molecules are smaller and more stable, allowing them to pass through the digestive system and enter cells more easily, where they are then converted into NAD+.
Safety, Side Effects, and What to Expect During Therapy
As with any therapeutic option, understanding the safety profile and potential side effects of NAD+ therapy is essential for making an informed choice.
Managing Side Effects During Your Session
While NAD+ is a natural compound already present in your body, introducing a concentrated amount directly into your bloodstream can cause acute, temporary physical reactions. In clinical settings, some patients experience:
- Moderate to severe abdominal cramping
- Nausea and a feeling of fullness in the chest
- Mild headaches or muscle pressure
- Brief episodes of dizziness or flushing
These symptoms are directly related to how fast the fluid is flowing. If the drip rate is too quick, your body may react with cramping or nausea. Our experienced medical staff manages this by starting with a very slow infusion rate and adjusting it based on your immediate comfort. For a broader look at the safety of these therapies, see our article on exploring the benefits and risks of nad injections for enhanced health.
Long-Term Safety and Quality Standards
To ensure a safe experience, it is vital to receive therapy under professional medical supervision. At Global Pain & Spine Clinic, we prioritize patient safety by using only high-quality, third-party-tested compounds.
Before starting any program, our medical team conducts a comprehensive clinical assessment to ensure the therapy is appropriate for your unique health profile. You can learn more about what to expect during an intravenous session in our guide on everything you need to know about getting an iv and explore our wider approach to wellness.
Alternative and Complementary Mitochondrial Therapies
While NAD+ is a key player in cellular energy, it does not work in a vacuum. Your mitochondria require a whole team of vitamins and minerals to function at their best.
Upstream Mitochondrial Support
Sometimes, addressing a cellular energy deficit requires looking “upstream” at other essential nutrients. For example, Vitamin B1 (thiamine) and magnesium are critical partners in the metabolic pathways that produce ATP.
If your body is low on thiamine or magnesium, simply adding more NAD+ may not resolve your fatigue, because the cellular machinery lacks the necessary cofactors to process it. Pairing your therapy with other targeted nutrients can create a powerful synergistic effect.

Lifestyle Factors for Cellular Health
No supplement or infusion can replace the foundational benefits of a healthy lifestyle. You can naturally support and maintain your cellular energy levels by focusing on:
- Regular Exercise: Physical activity, especially resistance and aerobic training, stimulates your cells to create more mitochondria and naturally boosts NAD+ production.
- Balanced Nutrition: Eating a diet rich in whole foods, lean proteins, and leafy greens provides the raw building blocks your body needs for metabolic health.
- Quality Sleep: Deep, restorative sleep is when your cells perform their most critical maintenance and repair work.

Frequently Asked Questions About NAD+ Therapy
Is there scientific evidence supporting NAD+ for long COVID?
Research into post-viral fatigue and long COVID is rapidly evolving. Many researchers believe that the long-term exhaustion associated with these conditions is tied to mitochondrial dysfunction and persistent cellular fatigue. While large-scale, definitive clinical trials are still ongoing, early observational data and patient reports suggest that supporting cellular energy pathways can be a helpful component of a comprehensive post-viral recovery plan. You can read more about the research on post-viral fatigue here.
How often should you get NAD+ infusions?
There is no single “one-size-fits-all” protocol for NAD+ therapy. The frequency and duration of your sessions depend entirely on your health goals, your current physical condition, and how your body responds to the initial sessions. Some individuals benefit from an initial series of closely spaced sessions followed by periodic maintenance, while others find that occasional single sessions meet their needs. For a more detailed breakdown, explore our nad infusions complete guide.
Can NAD+ therapy help with chronic pain management?
Yes, when used as part of a multidisciplinary treatment plan. Because NAD+ supports cellular repair, reduces oxidative stress, and plays a role in nerve health, it can help calm neuroinflammation. This makes it a valuable supportive therapy for individuals undergoing physical rehabilitation for chronic joint, spine, or nerve pain.
