What Is NAD+?
NAD+ stands for Nicotinamide Adenine Dinucleotide. It is a coenzyme that helps cells convert nutrients into usable energy and supports several biological processes.
NAD+ is involved in:
- Cellular energy metabolism
- Redox reactions
- DNA repair
- Cell signalling
- Mitochondrial function
- Regulation of certain enzymes
Because of these functions, researchers are studying NAD+ and NAD+-boosting approaches in relation to aging, metabolic health, neurological conditions, and other areas of medicine.
Why Is NAD+ Important for the Body?
NAD+ helps enzymes involved in energy production and cellular maintenance. It also acts as a substrate or cofactor in pathways involved in DNA repair and cellular signalling.
Research suggests that NAD+ availability can change with age. This has led scientists to investigate whether increasing NAD+ levels could have meaningful health effects. However, increasing NAD+ in the blood does not automatically mean that a person will experience a specific clinical benefit.
NAD+ Therapy: What Does It Mean?
NAD+ therapy refers to approaches intended to increase NAD+ availability in the body. These approaches may include:
1. NAD+ Infusion
Some wellness and clinical settings administer NAD+ intravenously. The evidence for IV NAD+ is still limited compared with the amount of interest surrounding the treatment.
A 2026 systematic review found that there were no eligible clinical outcomes trials demonstrating IV or intramuscular NAD+ itself for anti-aging or wellness indications.
2. NAD+ Precursors
Researchers have also studied compounds that the body can use to produce NAD+, particularly:
- Nicotinamide riboside (NR)
- Nicotinamide mononucleotide (NMN)
- Nicotinamide
- Nicotinic acid
Human studies have shown that some oral NAD+ precursors can increase NAD-related metabolites, but clinical outcomes have been variable.
What Does NAD+ Do?
NAD+ is the oxidized form of NAD and acts as an important coenzyme in the body.
Its functions include:
- Supporting cellular energy production
- Helping convert carbohydrates, fats, and proteins into energy
- Supporting normal cellular metabolism
- Participating in DNA repair processes
- Supporting mitochondrial function
- Helping regulate certain cellular enzymes
- Contributing to healthy cellular aging
Because NAD+ is involved in many biological processes, researchers continue to study its potential role in aging, metabolism, and cellular health.
NAD and Cellular Energy
Everything you need to know about nad
One of the best-known functions of NAD is its involvement in energy production.
When you eat food, your body breaks nutrients down into smaller molecules. NAD helps transfer electrons during metabolic reactions, allowing mitochondria to produce ATP, the primary energy currency used by cells.
This process is especially important because tissues and organs require continuous energy to perform their normal functions.
What Is NAD Therapy?
Everything you need to know about nad
NAD therapy refers to treatments designed to increase or support NAD availability in the body. Depending on the treatment approach, NAD may be administered directly or supported through NAD precursors.
NAD therapy is available in different forms, including approaches involving intravenous administration and oral supplementation. The appropriate approach can depend on individual needs, medical history, and professional assessment.
NAD therapy should be discussed with a qualified healthcare professional before starting treatment.
What Are the Potential Benefits of NAD?
NAD has several important biological functions, and research continues to investigate its potential benefits. Some areas of interest include cellular energy, metabolism, healthy aging, and cellular repair.
Potential areas associated with NAD include:
1. Supports Cellular Energy
NAD contributes to the processes that help cells produce ATP. Adequate cellular energy is essential for normal body function.
2. Supports Healthy Aging
NAD is involved in cellular processes associated with aging. Researchers are studying whether supporting NAD levels may contribute to healthy aging and cellular function.
3. Supports Mitochondrial Function
Mitochondria require NAD-related metabolic reactions to produce energy efficiently. NAD therefore plays an important role in normal mitochondrial activity.
4. Supports DNA Repair
NAD is used by certain enzymes involved in DNA repair and cellular maintenance. This makes NAD an important component of normal cellular health.
5. Supports Metabolism
NAD participates in metabolic reactions involving carbohydrates, fats, and proteins. Healthy NAD metabolism contributes to normal energy processing within cells.
6. Supports Cellular Function
Because NAD is involved in numerous biochemical reactions, maintaining appropriate NAD availability is important for normal cellular activity.
NAD and Healthy Aging
How Does NAD Therapy Work
Everything you need to know about nad
The exact process depends on the type of NAD treatment being used.
With intravenous NAD therapy, NAD-containing solutions are administered through an IV under professional supervision. The treatment is intended to make NAD available to the body without relying entirely on the digestive system.
The duration and frequency of treatment can vary depending on the individual’s circumstances and the healthcare provider’s protocol.
Before treatment, a healthcare professional may review medical history, current medications, health conditions, and treatment goals.
Who May Consider NAD Therapy?
Everything you need to know about nad
People interested in NAD therapy may be seeking support for areas such as cellular wellness, healthy aging, energy metabolism, or general wellness.
However, NAD therapy is not appropriate for everyone. A healthcare professional should determine whether a particular treatment is suitable based on an individual’s health status and medical history.
It is important to avoid starting NAD therapy solely because of online claims or testimonials.
Is NAD Therapy Safe?
Everything you need to know about nad
The safety of NAD therapy depends on the specific treatment, dose, method of administration, and individual health factors.
IV treatments can cause temporary effects related to the infusion itself. Some people may experience discomfort at the injection site, nausea, flushing, headache, or other temporary symptoms.
Anyone considering NAD therapy should discuss possible benefits, risks, alternatives, and expected outcomes with a qualified healthcare professional.

NAD Supplements vs NAD IV Therapy
NAD support can be approached in different ways.
NAD supplements generally involve oral products designed to provide NAD-related nutrients or precursors. The body processes these nutrients through normal metabolic pathways.
NAD IV therapy involves administering a solution directly into a vein under professional supervision.
These approaches differ in absorption, administration, treatment setting, and clinical considerations. A healthcare professional can help determine which approach, if any, is appropriate.

How Long Does NAD Therapy Take?
The duration of NAD treatment varies depending on the treatment method and individual protocol.
An NAD IV session may take a significant amount of time because the solution is administered gradually. The exact treatment duration can depend on the concentration, infusion rate, and healthcare provider’s protocol.
A consultation before treatment can help determine the expected session duration and number of treatments.
What Should You Expect During NAD Therapy?
During NAD IV therapy, a healthcare professional typically inserts an IV line into a vein and administers the solution gradually.
Patients may be monitored during the session for comfort and any potential reactions. Some people may notice sensations such as warmth, nausea, or discomfort during infusion.
If any unusual or uncomfortable symptoms occur, they should be reported to the healthcare professional immediately.
Are There Side Effects of NAD Therapy?
NAD therapy may cause side effects, particularly when administered intravenously.
Possible temporary effects may include:
- Nausea
- Headache
- Flushing
- Abdominal discomfort
- Dizziness
- Fatigue
- Injection-site discomfort
Side effects can vary from person to person. Professional assessment and appropriate monitoring are important when receiving IV-based treatments.
Who Should Avoid or Discuss NAD Therapy With a Doctor?
People with certain medical conditions, those taking medications, pregnant or breastfeeding individuals, and people with allergies or other health concerns should seek medical advice before considering NAD therapy.
A healthcare professional can review your medical history and determine whether NAD treatment is appropriate.
