Less NAD+ every year.
You feel it every afternoon.
The 3pm slump. The sleep that doesn't restore. Recovery that takes days, not hours. Much of it traces to one molecule.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme your body makes from forms of vitamin B3, and it takes part in many of the chemical reactions inside your cells. Scientists have studied it for over a century and research is ongoing. Our Science page sets out what the published studies do and don't show.

Before your first order
Does it hurt?
The pen uses micro-needles designed for near-painless subcutaneous administration — most clients say it's far easier than they expected.
I've never self-administered anything — will I manage?
Yes. Every kit includes Raquel's step-by-step protocol guide, and the clinic is a WhatsApp message away whenever you need a hand.
What's the difference between a starter kit and refill cartridges?
A starter kit has everything you need to begin: the pen, cartridges, needles, alcohol wipes, a sharps bin and a cold pack. Refill cartridges are for customers who already have a RevIVe pen.
Can I pause or cancel my subscription?
Any time, with no fees. Pause, change or cancel before your next dispatch date — you're in full control.
Built around one non-negotiable:
purity you can verify.
Raquel has spent over ten years delivering IV therapy in UK clinics. She wouldn't put NAD+ in clients' hands until she found a source she could verify — every batch, independently, with a certificate to show for it. That standard is the company.
