Does NAD⁺ need to be refrigerated?
Yes. Store your NAD⁺ in the fridge once it arrives. Longevity Pen NAD⁺ cartridges are formulated to stay stable for at least 2 weeks at room temperature, so shipping, a day out of the fridge or a short trip is no problem. Away from a fridge for a while? Use the included ice pack and travel case.
As our Longevity Pen NAD⁺ reaches customers around the world — from the Netherlands to the USA, Australia, and beyond — a question comes up often:
“Is NAD⁺ stable without refrigeration during shipping?”
It's a fair concern, especially for a molecule as important as NAD⁺. That's why we're breaking it down — clearly and transparently.
Yes — Our NAD⁺ can handle the journey
Our NAD⁺ is formulated to remain stable for at least 2 weeks at room temperature — even during transit through warmer climates. Why? Because we know shipping delays happen. And we built our formulation to reflect real-world logistics — not lab-only conditions. That's why we ship exclusively with DHL Express, ensuring fast and controlled delivery anywhere in the world.
What makes it so stable?
It's not just about packaging — it's about how the molecule is made. Our NAD⁺ is produced using a 5-step enzymatic process that mirrors how your body naturally builds NAD⁺. No shortcuts. No synthetic forcing. No mannitol. Just non-GMO nicotinamide, gentle transformation, and deep purification. This leads to a molecule that's not just “similar” to NAD⁺ — it's biologically identical: clean, calm, and inherently stable, even without support structures or fillers.
What to do once it arrives
While it can travel well, we still recommend: store your NAD⁺ in the fridge once delivered, or use the included ice pack and case for short-term room-temp use. This ensures it stays fresh for weeks to months, depending on usage.
A molecule that doesn't need a crutch
We don't add mannitol to mask fragility or pad the powder. Because our NAD⁺ doesn't need it. Its stability is built-in — thanks to a process that respects biological intelligence, not industrial speed.
Final word: Confidence in every delivery
From sourcing to shipping, every part of our process is built for purity, resilience, and trust. So wherever you're ordering from — and however far it travels — you can feel confident that what you receive is authentic, stable, and ready to support your daily wellness routine.
Mixing NAD⁺ from powder yourself?
How long self-mixed NAD⁺ keeps depends on the product and how it was prepared. Follow your supplier's instructions.
Longevity Pen cartridges come pre-filled and ready to use. No mixing, no reconstitution. See the NAD⁺ starter kit
