Scorecard
- Potency — Mixed. IV does deliver 500–1000mg NAD+, but most degrades to nicotinamide in plasma before reaching cells.
- Bioavailability — Weak. Oral NMN/NR is cheaper and arguably reaches mitochondria as effectively; the IV pain does not translate to better outcomes.
- Marketing vs hype vs reality — Weak. "Longevity drip" language; zero human RCTs supporting the anti-aging claims at this dose.
- Sustainability — Weak. Single-use IV bag, tubing, needle, cannula, medical-waste stream for every 90-minute drip.
- Ethics — Weak. €600–€900 price preys on biohacker anxiety; sold by clinics with direct conflict of interest.
Verdict: Avoid.
You walk into a longevity clinic in Mayfair, Marylebone, or any "wellness lounge" in Notting Hill. They sit you in a recliner that looks like a first-class plane seat. They hang a bag of pink-tinted fluid. They tell you NAD+ is "the molecule that reverses ageing." Ninety minutes and £600–£1,200 later, you walk out feeling slightly sick, slightly euphoric, and convinced you've just done something profound.
You haven't. You've mostly funded a very expensive flush.
NAD+ is real biology. The IV bag is mostly marketing. Those are two different sentences and the clinics blur them on purpose.
What's actually true. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme every cell in your body uses to make energy and run repair enzymes called sirtuins. Levels do decline with age. Raising intracellular NAD+ in mice does some genuinely interesting things to mitochondrial function. None of that is in dispute.
What's not true. That dripping NAD+ directly into a vein meaningfully raises intracellular NAD+ in your tissues. The molecule is huge and unstable in the bloodstream. It gets broken down almost immediately into smaller precursors (nicotinamide, nicotinic acid) which then have to be transported into cells and rebuilt into NAD+. In other words: your body is doing the same thing it would do with a €15 bottle of niacin, except you paid €800 and sat in a chair for two hours.
There is, to date, no published human trial showing that IV NAD+ raises tissue NAD+ better than oral precursors. The "I felt amazing" effect that clinics weaponise in testimonials is almost certainly a combination of: the niacin flush (vasodilation, warmth, head rush), saline rehydration, placebo from the setting, and the simple fact that you sat still for 90 minutes in a calm room — which, ironically, IS a nervous-system intervention, just not the one you paid for.
The most expensive part of the drip is the chair, the lighting and the gowned receptionist. The molecule is the cheap bit.
The polyvagal bit, because we owe you one. The reason people swear by these drips isn't NAD+. It's that for 90 minutes nobody can email you, you're horizontal, the lights are dim, and a stranger is being kind to you. That's down-regulation of the sympathetic nervous system. You can replicate it with a €20 weighted blanket and an afternoon off your phone. We're not joking.
Who actually benefits from raising NAD+. People over 50 who genuinely want to experiment with cellular ageing protocols, people with certain mitochondrial conditions, and people in a clinical trial. For all of them, the evidence-based route is oral NR (nicotinamide riboside) or NMN — both of which are absorbed, both of which have human trials showing raised blood NAD+, both of which cost €40–€80 per month instead of €800 per session.
Who should walk out of the clinic. Anyone under 40 with no specific condition. Anyone using it as a "hangover cure" (it's a hangover cure the same way a £600 taxi is a hangover cure — it works because you slept). Anyone whose clinic is also selling you "ozone therapy" and "glutathione pushes" in the same visit — that's a red flag the whole menu is theatre.
Bottom line. Skip the drip. If you actually want to test NAD+ optimisation, take an oral precursor for 90 days and see how you feel. We're carrying clean, third-party-tested options in the shop below.
Our sister site Kokorology covers the longevity-industry psychology in more depth. The clean products we'd actually buy are right here.
- Potency
- Mixed. NAD+ is a real molecule. IV delivery is mostly theatre — most is degraded or excreted before reaching the cells that need it.
- Bioavailability
- Weak. Oral NR/NMN raises serum NAD+ as effectively at a tiny fraction of the cost. IV adds risk, not absorption.
- Marketing vs hype vs reality
- Poor. Longevity-clinic positioning for a delivery route the evidence does not support.
- Sustainability
- Weak. Single-use IV kits, needles, plastic tubing, refrigerated logistics.
- Ethics
- Poor. The clinics selling it know the oral form does the same job. They sell the needle because the needle is what justifies the EUR 800.
- Verdict
- EUR 800 for a placebo with a needle.
