NAD+ Storage and Travel Tips: Keeping Your Kit Stable On the Go | MyNad+

If you've ordered an at-home NAD+ kit, storage and travel tips matter almost as much as the injection itself — NAD+ solution is genuinely fragile stuff. It's sensitive to both heat and light, so how you keep it in your fridge between doses, and how you handle it on a weekend away or a flight abroad, has a real bearing on whether the product still performs as intended. The short version: keep it refrigerated at 2–8°C, out of direct sunlight, and if you're travelling with it in the UK, pack it in your hand luggage along with some form of documentation explaining what it is.

Storing your NAD+ kit at home

Always start with the instructions included in your specific kit, since exact handling can vary slightly between products. As a general rule, though, NAD+ solution should be stored in a standard fridge at 2–8°C, kept upright, and left in its original box or an opaque container rather than sitting in the fridge door where temperature swings are greater. NAD+ is also light-sensitive — it can undergo photochemical breakdown when exposed to UV and visible light — which is part of why kits typically ship in amber vials or dark packaging. Once a vial has been reconstituted, avoid refreezing it; repeated freeze-thaw cycles are generally not recommended for reconstituted solutions and can affect stability.

What happens if NAD+ is left out of the fridge

Some compounding pharmacy and manufacturer guidance suggests that reconstituted NAD+ solution can lose a meaningful share of its potency within around 24 hours at room temperature, with degradation becoming more significant over the following few days. That doesn't mean a few minutes on the counter while you prepare an injection is a problem — it isn't, in most guidance — but leaving a vial out for an extended period, or somewhere warm like a car glovebox or a sunny windowsill, is worth avoiding. If you're ever unsure whether your kit has been stored correctly, it's best to check with the supplier before using it.

NAD+ storage and travel tips for flights and trips away

Travelling with an injectable kit understandably raises questions, but UK rules are more accommodating than most people expect. According to gov.uk guidance on hand luggage, essential liquid medicines over 100ml are allowed through security, though you'll need proof it's prescribed to you — a letter from a doctor or a copy of a prescription — for larger liquid volumes. Needles and syringes are explicitly permitted in both hand and hold luggage with no extra restriction beyond normal screening.

Because NAD+ isn't a medicine licensed by the MHRA, it sits in a slightly different category to a prescribed drug, so it's sensible to carry a short covering letter or your order confirmation explaining what the kit is and why you're carrying it, even where it isn't strictly mandatory. You can read more about how NAD+ is currently regulated in the UK in our guide, Is NAD+ Legal in the UK?. It's also worth checking the rules of wherever you're heading, since import and carriage rules for self-administered injectable products vary by country, and contacting your airline a few days ahead of travel if you're at all unsure.

Keeping your kit cool while you're away

Once you're travelling, the same 2–8°C target still applies — you're just working without a fridge for part of the journey. An insulated travel wallet or cool bag, the kind commonly used for insulin or other refrigerated medication, is the simplest way to bridge the gap. Wrap any ice packs rather than letting them touch the vial directly, since direct contact can risk freezing the solution rather than just cooling it. Most guidance treats a few hours of transit at ambient temperature as low-risk, but the goal is always to get the kit back into a fridge — a hotel mini-fridge on arrival works fine — as soon as it's practical to do so.

Sharps and disposal on the road

Used needles and syringes should always go into a proper sharps container, never loose into general rubbish, whether you're at home or away. Travel-sized sharps bins are inexpensive and pack easily alongside the rest of your kit. Many UK pharmacies and council household waste recycling sites will take a sealed sharps container for safe disposal — it's worth checking ahead if you're relying on this while away from home. If no disposal option is available at your destination, the safest approach is to bring the sealed container back with you rather than disposing of it informally.

Frequently Asked Questions

Can I put my NAD+ vial in checked luggage instead of hand luggage?

You can, since UK rules permit both liquid medicines and syringes in hold luggage, but hand luggage is generally the safer choice. Hold baggage sits in an unheated, unpressurised cargo area for the length of the flight, and there's a higher risk of loss, delay or rough handling. Keeping your kit with you also means you can control its temperature and access it if needed.

Do I need a doctor's letter to travel with NAD+ syringes?

Not strictly, for basic security screening of needles and syringes in reasonable quantities. However, since NAD+ isn't an MHRA-licensed medicine, a short letter or your order confirmation explaining what the product is can make screening smoother and is worth having, particularly for larger liquid volumes over 100ml, where gov.uk guidance recommends carrying proof of what it's for.

How long can NAD+ be left unrefrigerated during travel?

Most manufacturer and pharmacy guidance treats a few hours at room temperature during transit as low risk, but reconstituted solution isn't designed to sit out indefinitely — some sources suggest a meaningful drop in potency can begin within around 24 hours. Using an insulated cool bag and getting the kit back into a fridge as soon as you reasonably can is the safest approach.

Will airport security let me carry my NAD+ kit through screening?

Under current UK hand luggage rules, syringes and prescribed or essential liquid medicines are permitted through security, and officers may ask to inspect the container as part of normal screening. Since NAD+ sits outside standard MHRA licensing, carrying documentation that explains what the kit is and why you have it is a sensible precaution, alongside checking your specific airline's own policy in advance.
