Clinicians' Choice

Pharmaceutical-grade NAD⁺, manufactured in the United Kingdom.

A pre-mixed nasal spray delivering concentrated NAD⁺. Designed for everyday maintenance, and for anyone who wants NAD⁺ without injections.

NAD⁺ is a coenzyme found in every cell, involved in cellular energy production. Levels naturally decline with age.

One spray per nostril in the morning, as directed. Nothing to draw up, mix or calculate.

Start low and build consistency, adjusting to your own routine and tolerance.

Free UK delivery, with UK-based support if you need it.

Your next bottle arrives before you run out, so the daily routine never breaks. Pause or cancel anytime from your account.

Absorption

Most NAD⁺ is swallowed. Most of it never arrives.

The difference is not the molecule. It is the route it takes.

Swallowed
Broken down before it arrivesTaken by mouth, NAD⁺ meets the digestive system before it ever reaches the bloodstream.
Sprayed
Absorbed through the nasal liningA mist is taken up through the tissue inside the nose, so the gut never gets the chance.

Same molecule. The only thing that changes is the door it comes in through.

The molecule

Inside every cell, NAD⁺ powers the processes that keep you alive.

The NAD+ coenzyme molecule

Not a stimulant, not a vitamin. A coenzyme your cells cannot run without.

A human cell

Present in every cell

NAD⁺ is a coenzyme found in all your cells. It is the cofactor that lets energy and repair systems switch on when they are needed.

A mitochondrion

Carries the energy

It shuttles power from the food you eat, becoming NADH and driving ATP production inside the mitochondria.

A depleted human cell

Falls as you age

Levels decline naturally over time. The spray is there to help you keep your intake consistent, without waiting rooms or appointments.

What depends on it

Four systems that cannot run without NAD⁺.

None of this is about the spray. It is what the molecule does once it is there.

Energy

Powering the mitochondria

NAD⁺ carries the electrons that drive ATP production. Without it the chain stops.

Repair

Rebuilding damaged DNA

PARP enzymes consume NAD⁺ each time they repair a broken strand. Repair spends the pool.

Signalling

Deciding what runs when

Sirtuins use NAD⁺ as a substrate to regulate which cellular programmes are switched on.

Metabolism

Turning food into fuel

The redox reactions that break food down into usable energy require NAD⁺ at every step.

Two of those four consume the molecule outright. Which is why the pool is never static, and why it can fall.

The simplest way to picture it

Think of it as your cellular battery.

Same body, same day ahead. What changes is how much charge you start with.

A fully charged battery In your twenties

You start the day full

NAD⁺ is abundant. Every system that runs on it has as much as it needs, and you never think about it once.

A battery running low By your forties

You start the day half empty

The same battery no longer holds what it used to. You feel it in the afternoons, and you put it down to getting older.

Topping your NAD⁺ back up is how you get that charge back, and the spray is the cleanest way to do it.

Made to a standard

What you are actually buying.

No proprietary blend, no vague wording. Three things, stated plainly.

Format
Pre-mixed, ready to useNo syringes, no reconstitution, nothing to measure at the kitchen table.
Storage
Room temperatureKept upright, out of direct sunlight and heat. It travels without a cool bag.
Support
A UK-based teamReachable by a person, not a form that disappears.

Our ingredients

Two ingredients. Nothing else in the bottle.

No buffers, no preservatives, no stabilisers. Stability comes from how it is manufactured, not from what is added to it.

The NAD+ molecule

NAD⁺

The active Nicotinamide Adenine Dinucleotide

The primary active ingredient, supporting cellular energy production, mitochondrial function and NAD⁺ metabolism.

Water for Injection

Pharmaceutical-grade sterile water. The only other thing in the formulation.

Questions

The things people ask before they order.

Their guidance is to start low and build consistency: one spray per nostril in the morning, adjusted to your own routine and tolerance.

Upright, at room temperature, away from direct sunlight and heat. No refrigeration, which is what makes it straightforward to travel with.

The solution should be clear. If the bottle looks damaged or the liquid is discoloured, do not use it and contact the team.

NAD⁺ is a coenzyme your body already makes and uses in every cell. What is in the bottle is pharmaceutical-grade NAD⁺ and water for injection, made in the United Kingdom, with nothing else added. If you have a diagnosed medical condition, take prescription medication, or are unsure whether it is right for you, speak to your GP or pharmacist before you start.

Do not use it if you are pregnant or breastfeeding, or if you are under 18. Speak to your GP or pharmacist first if you take prescription medication, have a diagnosed medical condition, or have had problems with nasal sprays before.

The most likely is irritation inside the nose. Some people find a nasal spray does not suit them, and if it leaves your sinuses sore or blocked, stop and speak to your healthcare provider rather than pushing on.

Yes. The plan is managed by you and can be paused, skipped or cancelled at any time, with no minimum term.
