NAD+ Infusions: What the Longer IV Session Involves

Most IV drips on a wellness menu take well under an hour. NAD+ is different. It is usually infused slowly, over a period that can stretch past two hours, and people who book it are often surprised by how the session feels compared with a quick hydration drip. In Los Angeles, and particularly in wellness-focused neighborhoods such as West Hollywood, it has become one of the more talked-about offerings.

This article explains what NAD+ is, why it plays a role in the body, why infusions are given slowly, what patients commonly experience during a session and what the research does and does not show. It also covers the screening and practical preparation that make a long IV session safer and more comfortable.

What NAD+ Is

NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme found in every living cell. Coenzymes are helper molecules that allow enzymes to carry out chemical reactions. NAD+ is central to the reactions that turn food into usable energy, and it also takes part in processes involved in cell maintenance and repair.

The body makes NAD+ from building blocks that come from the diet, including forms of vitamin B3 such as niacin and nicotinamide. It is not a vitamin itself, but it depends on vitamin B3 for its production.

NAD+ works in a cycle. It picks up electrons in one reaction, becoming a slightly different form called NADH, and hands them off in another, returning to NAD+. That shuttle is part of how cells extract energy from nutrients. Because the same molecules are reused again and again, the body maintains a pool of NAD+ that it constantly recycles and replenishes. Diet, activity, sleep and overall health can all influence that pool.

The body also uses NAD+ as a raw material for certain enzymes involved in repairing DNA and regulating cellular stress responses. Those uses consume NAD+ rather than recycling it, which is part of why researchers have become interested in how levels change with age and illness.

Why NAD+ Draws Interest

Research in cells and animals has shown that NAD+ levels tend to decline with age, and that NAD+ is involved in processes linked to aging and metabolism. Those findings have fueled interest in ways to raise NAD+ levels, including oral supplements of its precursors and intravenous NAD+.

That interest has moved quickly from laboratories to wellness clinics. The gap between what has been shown in cells and animals and what has been demonstrated in people is important to keep in mind when evaluating claims.

How NAD+ Is Delivered

NAD+ and its precursors can be taken in several ways.

Route	How it works	Notes
Oral precursors	Supplements such as nicotinamide riboside or nicotinamide mononucleotide	Converted to NAD+ in the body
Intravenous infusion	NAD+ diluted in IV fluid and infused slowly	Requires a clinical setting or supervised mobile visit
Injection	Smaller doses given under the skin or into muscle	Offered by some providers
Nasal spray	Offered by some providers	Less commonly used

Each route delivers different amounts in different ways, and they are not interchangeable, so comparisons between them should be made carefully.

Why the Infusion Is Slow

NAD+ infusions are typically run much more slowly than standard hydration drips. One West Hollywood mobile provider reports that most IV sessions take 35 to 45 minutes, while NAD+ sessions take one and a half to two and a half hours.

The main reason is comfort. When NAD+ is infused quickly, many people experience uncomfortable sensations, such as chest tightness, flushing, nausea or cramping. Slowing the infusion usually eases these sensations. The nurse adjusts the rate throughout the session based on how the patient feels, sometimes slowing or pausing the drip before resuming.

What Patients Commonly Feel

Experiences vary, but common reports during a NAD+ infusion include:

• A feeling of pressure or tightness in the chest or abdomen
• Warmth or flushing
• Mild nausea or stomach cramping
• Restlessness or a feeling of needing to move
• A sense of fatigue or heaviness

These sensations usually fade when the infusion is slowed. Telling the nurse right away when something feels uncomfortable is important, since the rate can be adjusted in real time. Any symptom that feels severe, such as significant chest pain, difficulty breathing or fainting, should be reported immediately so the infusion can be stopped and the situation assessed.

Preparing for a Long Session

Because NAD+ sessions are long, preparation makes a difference:

1. Eat a light meal beforehand, since an empty stomach can make nausea worse
2. Drink water in the hours before the session
3. Wear comfortable clothing with sleeves that roll up easily
4. Plan to stay seated for up to two and a half hours or more
5. Keep a book, headphones or a phone charger nearby
6. Avoid scheduling important commitments immediately afterward

For mobile visits, choosing a quiet, comfortable spot at home or in a hotel room helps the time pass more easily. A reclining chair or a bed with pillows supporting the arm keeps the IV site steady during the long session, and having a restroom nearby is practical, since some people need a short break partway through.

Screening and Who Should Be Cautious

Like any IV therapy in California, NAD+ infusions require screening and an order from a licensed provider. Legal guidance for California IV therapy businesses describes a good faith examination by a physician, nurse practitioner or physician assistant before a registered nurse administers treatment.

People who may need extra caution or a different approach include those with heart conditions, kidney or liver disease, anyone who is pregnant or breastfeeding, people with a history of significant reactions to IV therapy and those taking medications that could interact. Screening is the step where a provider decides whether NAD+ is appropriate and at what rate.

What the Research Shows So Far

The science of NAD+ is active and evolving. Studies in cells and animals have produced interesting results about metabolism and aging. Human studies, particularly of oral precursors, have examined safety and whether NAD+ levels rise, with more mixed evidence on whether that translates into meaningful health benefits.

Research specifically on intravenous NAD+ in healthy adults is more limited. Many claims made for NAD+ infusions, such as improved energy, mental clarity or anti-aging effects, have not been established through large, well-controlled human trials.

Question	Current state of evidence in broad terms
Does NAD+ play a role in energy metabolism?	Yes, well established
Do NAD+ levels decline with age?	Supported by research, largely from animal and some human studies
Do oral precursors raise NAD+ levels in people?	Some studies show increases
Do IV NAD+ infusions produce lasting health benefits in healthy adults?	Not well established

Comparing NAD+ With Standard Drips

NAD+ sessions differ from standard hydration and vitamin drips in several practical ways. They take longer, often cost more and are more likely to produce noticeable sensations during the infusion. Standard drips focus on hydration and vitamins, with effects that are easier to predict, while NAD+ is chosen for different reasons and with less established outcomes.

For someone who mainly wants to rehydrate after illness, travel or a long day, a standard drip is usually simpler. For someone curious about NAD+, understanding the time commitment, the likely sensations and the limits of current evidence helps set realistic expectations.

What NAD+ Marketing Often Leaves Out

Marketing for NAD+ tends to highlight research on aging and energy. It often leaves out that much of that research comes from cells and animals rather than controlled human trials of IV NAD+.

It also tends to understate the session itself. A two-hour infusion with periods of discomfort is a different experience from a quick drip, and people benefit from knowing that beforehand.

Finally, marketing rarely mentions the role of the nurse in adjusting the rate. Slow, attentive administration is what makes the session tolerable for most people.

Short Answers on NAD+ Infusions

People considering IV therapy visits across Hollywood can ask how NAD+ sessions are scheduled, how long they take and how the rate is adjusted. Lively Drops, which lists its location on Hollywood Boulevard, is one of the mobile providers serving West Hollywood and surrounding areas, with NAD+ sessions that typically take one and a half to two and a half hours and a medical screening reviewed by a licensed provider before each visit.

What is NAD+?
A coenzyme found in every cell that plays a central role in energy metabolism.

Why does a NAD+ infusion take so long?
Slow infusion reduces uncomfortable sensations such as chest tightness, flushing and nausea.

Is there strong evidence for NAD+ infusions?
Human evidence for lasting benefits of IV NAD+ in healthy adults is limited.

How should someone prepare?
Eat lightly, hydrate, dress comfortably and plan for a long session.

NAD+ infusions are a longer, more involved form of IV therapy than a standard drip. Knowing what NAD+ is, why the session is slow, what it may feel like and what the evidence supports helps people decide whether it fits their goals.
