NAD+ drips: what to expect

GP-led and medically reviewed by our clinical team
Published 15 October 2026 · 5 min read

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It helps turn food into energy and is involved in repairing cells. Your body makes it from vitamin B3 and other building blocks in your diet.

The short answer

NAD+ is a molecule every cell uses to make energy. NAD+ drips are popular in wellness and longevity circles, but the research is at an early stage and there is no high-quality evidence yet that they improve health in people who are already well. If you choose one, expect it to run slowly, over 2 or 4 hours.

What is NAD+?

Levels of NAD+ fall with age in some studies. That finding is why NAD+ has attracted so much interest, but lower levels with age do not prove that topping them up improves health.

What the evidence says

Most research on NAD+ is in animals, small human studies or case reports. Some small studies show that NAD+ given into a vein raises NAD+ levels in the blood. There is not yet good evidence that this improves energy, ageing or long-term health. Our guide to how medical evidence works explains where this sits.

Why people book it

People tell us they book NAD+ because it is widely talked about in wellness and longevity circles, or because they want to try it for themselves. These are reasons clients give, not promises of results.

What the drip feels like

NAD+ has to run slowly. If it runs too fast, it can cause:

Flushing or feeling hot
Nausea or an upset stomach
Muscle cramps
A tight feeling in the chest

These usually ease quickly when the drip is slowed down. Your nurse adjusts the rate to keep you comfortable and stays with you throughout. Bring a book, or work quietly.

Our NAD+ options

NAD+ shot (an injection, not a drip): 15 min, £150 in clinic, £250 at home or hotel
NAD+ 250: 2 hours, £375 in clinic, £475 at home or hotel
NAD+ 500: 4 hours, £575 in clinic, clinic only

NAD+ 500 is given at our Nine Elms clinic only, because it takes 4 hours.
