Elixir sells devices and accessories only and makes no medical claims. NAD+ is a prescription-only medicine: cartridges are supplied through our registered UK pharmacy partner. 18+, UK only.

The NAD+ Starter Kit is what a serious routine deserves. At its centre is the reusable Elixir Pen — matte-finished, beautifully weighted, with a clear dose window — built to feel the same on day one and day five hundred. Around it, the insulated cooling bag keeps temperature-sensitive cartridges cool and organised, at home or in a weekend bag.

  • A reusable, precision-engineered pen — not a disposable
  • Cartridge-ready system in the standard format
  • Insulated cooling for temperature-sensitive cartridges
  • Everything in its place: cushioned, discreet, travel-ready
  • Designed in the UK, checked piece by piece before it ships

Curious about NAD+ itself? Start with The Science, then take the eligibility check — a licensed UK prescriber decides whether it's suitable.

  • The Elixir Pen — reusable, matte-finished, precision-weighted, clear dose window
  • The Cooling Bag — embroidered, insulated, zipped; protects and organises the whole kit
  • Cartridge system — accepts the standard cartridge format (anything prescription-only is supplied separately, after a prescriber's approval)
  • The gift box — magnetic-close, made to be kept
  • The care & travel guide — look after the kit, and travel with it properly
  • 1 · Unbox. Everything arrives together in the magnetic gift box, cushioned and organised.
  • 2 · Keep it cool. Temperature-sensitive cartridges live in the insulated cooling bag, at home or on the move.
  • 3 · Load. The pen accepts the standard cartridge format with a simple, positive click.
  • 4 · Follow your prescriber's directions. If you're on the supported programme, your dosing schedule comes from your licensed prescriber — never from us.

Full written instructions are included in the box, and our team is a message away after you order.

  • Does the kit include NAD+? The kit is the objects — pen, cooling bag, box. NAD+ refill cartridges are supplied through our registered UK pharmacy partner — see the cartridges.
  • Is £280 the final price? £280 is our introductory price and will be confirmed at checkout launch.
  • Is the pen reusable? Yes — it's engineered to be kept, not replaced.
  • Is delivery discreet? Yes. Plain, protective packaging, always.
  • What if it isn't right for me? The 90-day promise: we'll make it right, money back.

Why people look into NAD+

Built around a supervised routine.

NAD+ is a prescription-only medicine, assessed and prescribed by independent licensed UK clinicians and dispensed by a regulated pharmacy. We are not permitted to describe it, so we do not. What we make is the kit that keeps such a routine organised, cool and easy to travel with.
