What is NAD+ IV Therapy?

Definition and how it works

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme present in every cell, vital for energy production (ATP), DNA repair, and sirtuin regulation. NAD+ IV therapy delivers this coenzyme directly into the bloodstream, achieving plasma levels impossible to reach with oral supplementation. NAD+ levels decline by up to 50% between the ages of 40 and 60 — a process directly linked to ageing.

Origin and history

NAD+ was discovered by Harden and Young in 1906. Its central role in longevity was revealed by research at MIT and Harvard between 2013 and 2020, sparking a global boom in longevity clinics.

Benefits of NAD+ IV Therapy

Noticeable increase in energy and mental clarity

Activation of sirtuins (longevity enzymes SIRT1–SIRT7)

Accelerated DNA repair and reduced oxidative damage

Improved cognitive function and neuroprotection

Support for detoxification and craving reduction

Enhanced insulin sensitivity and metabolic function

NAD+ IV Therapy protocol step by step

1

Baseline blood work

Plasma NAD+ measurement, liver and kidney function tests before starting.

2

Venous access

Peripheral IV cannulation. Drip started at a low rate (10 mg/min).

3

Progressive infusion

Dose of 250–1,000 mg over 1.5–4 hours. Rate adjusted based on tolerance.

4

Monitoring

Heart rate, blood pressure and symptom checks. Medical staff present throughout.

5

Post-infusion

Oral hydration. Energy and cognitive effects logged over the following 24–48 hours.

The science behind NAD+ IV Therapy

Scientific evidence summary

Research at Harvard University (Dr. David Sinclair's lab) shows that restoring NAD+ levels activates sirtuins and the mTOR pathway, reversing epigenetic ageing markers in animal models. Clinical trials in humans (Washington University, 2018) confirm improvements in insulin resistance and muscle function with NAD+ precursor infusions. IV bioavailability is 6–10 times higher than oral.

Frequently asked questions about NAD+ IV Therapy

Does the infusion hurt or cause side effects?
The infusion may cause a sensation of warmth, chest tightness, or mild nausea if administered too quickly. At quality clinics the drip rate is individually adjusted to minimise these effects. They usually resolve by slowing the rate.
How long does a NAD+ IV session take?
Between 1.5 and 4 hours depending on the dose (typically 250–1,000 mg). Some clinics offer accelerated high-dose infusions with continuous medical supervision.
What's the difference between NAD+ IV and NMN/NR supplements?
Oral NMN and NR supplements are precursors the body converts into NAD+, with limited conversion efficiency. NAD+ IV delivers the coenzyme directly to the bloodstream with maximum bioavailability.
