Niagen (NR) NAD+ precursor: Everything You Need to Know About Boosting your NAD+ & Cellular Health
The Power of NAD+: Fueling Your Body at a Cellular Level
What is NAD+?
The Essential Coenzyme for Energy, Repair, and Wellness Support
Nicotinamide Adenine Dinucleotide (NAD+) is a coenzyme found in every living cell. It plays a central role in cellular energy production and supports normal metabolic processes.
NAD+ is involved in how the body converts nutrients into energy and helps maintain normal cellular function.
Levels of NAD+ tend to decline with age and other lifestyle factors. Because of this, NAD+ has become an area of interest in wellness and longevity research.
IV therapy and injections are used in clinical settings to deliver NAD+ directly into the body as part of a provider-guided plan.

How This Works in the Body
NAD+ is involved in hundreds of enzymatic reactions and supports several key biological processes in the body
Energy Production
Every cell in the body relies on mitochondria to generate energy. NAD+ is involved in cellular processes that help convert nutrients into usable energy within the body
DNA Integrity and Cellular Defense
Cells are continuously exposed to internal and external stressors. NAD+ is involved in cellular processes that help maintain normal DNA integrity and support overall cellular function.
Brain Function & Cognition
The brain is one of the most energy-demanding organs in the body. NAD+ plays a role in normal cellular processes that support neuronal activity and overall brain function.
Metabolism and Detoxification
NAD+ is involved in metabolic pathways that help regulate how the body processes nutrients and produces energy at the cellular level.
Niagen®: Unlocking Your Body’s Natural NAD+ Potential
What is Niagen?
The patent form of Nicotinamide Riboside (NR).
A vitamin B3 derivative, Niagen® serves as a precursor to NAD+, a coenzyme involved in cellular energy production.
Unlike direct NAD+ infusions, Niagen® provides the building blocks your body uses to produce NAD+ through its natural metabolic pathways.
NAD+ levels may decline over time due to age and lifestyle factors. Supporting NAD+ production has become an area of interest in wellness and cellular health research.

Niagen Injection (100mg)
A quick and convenient option for those looking to boost NAD+ levels naturally with a precursor-based approach.
Niagen IV Therapy 250mg or 500mg
A high-dose intravenous infusion that provides nicotinamide riboside (NR) to support natural NAD+ production and cellular health.
Enhancing Transparency: A Closer Look at Niagen IV Therapy
At iv&co, we are committed to providing science-backed, transparent education to help you make informed decisions about your wellness. While both NAD+ IV and Niagen IV boost NAD+ levels, recent research suggests Niagen IV may offer notable advantages in terms of infusion time, tolerability, and efficiency in elevating NAD+ levels.
Fewer Side Effects & Improved Tolerability
While IV therapy is a powerful wellness tool, the experience should also be comfortable and well-tolerated.
- Participants who received NAD+ IV Therapy commonly reported nausea, headaches, chest tightness, hot flashes, stomach cramping, and digestive discomfort. Some even experienced sudden bowel urges during treatment.
- By contrast, those receiving Niagen IV reported mild sensations of tingling, nasal congestion, and slight pressure in the head or ears, with significantly fewer side effects overall.
For individuals who struggle with the discomfort associated with NAD+ IV therapy, Niagen IV may offer a more pleasant and tolerable experience.
Reduced Inflammatory Response
Another key finding from this research is that NAD+ IV Therapy may trigger an inflammatory immune response, while Niagen IV does not.
- NAD+ IV led to an increase in white blood cell count, a possible indication of the body perceiving extracellular NAD+ as a sign of cellular trauma or damage. This may contribute to inflammation following treatment.
- Niagen IV, however, safely elevated NAD+ levels intracellularly without increasing inflammation or white blood cell activity.
For those looking to avoid potential inflammatory responses, Niagen IV may provide a safer, more natural way to boost NAD+.
Faster Infusion Time
Time is a valuable resource, and one of the key benefits of Niagen IV is its significantly shorter infusion time compared to NAD+ IV.
- In one study, participants receiving Niagen IV completed their infusions in an average of 2 hours and 7 minutes, while NAD+ IV took over 3 hours on average, with some lasting up to 4.5 hours.
- A second study showed even greater variation, with Niagen IV infusion times ranging from just 10 minutes to 3 hours, whereas NAD+ IV ranged from 20 minutes to over 3 hours—a 75% reduction in total infusion time for Niagen IV.
For those looking for a more time-efficient treatment, Niagen IV may be a preferable option.
More Rapid NAD+ Elevation
While both therapies aim to increase NAD+ levels, studies indicate that Niagen IV produces faster results.
- Niagen IV increased NAD+ levels by an average of 20% within 3 hours of the infusion. Levels remained elevated at 16% higher than baseline 24 hours later and 8.1% higher one week later.
- NAD+ IV took significantly longer to elevate NAD+ levels, with an increase of only 2% at the 24-hour mark. Levels peaked 14 days post-infusion at a 15.1% increase.
For those looking to boost NAD+ levels more quickly and efficiently, Niagen IV may provide a faster-acting solution.
What This Means for You
Both NAD+ IV and Niagen IV may help support cellular energy, longevity, and overall wellness, but based on recent findings, Niagen IV may offer:
✔ A shorter, more comfortable infusion process
✔ Fewer side effects and improved tolerability
✔ Faster elevation of NAD+ levels in the bloodstream
✔ A reduced likelihood of triggering an inflammatory response
As always, the best choice depends on your individual health goals and response to treatment. If you’d like to discuss which option is right for you, our team at iv&co is happy to help.
