Managing Diabetes While Traveling

Best Low Blood Sugar Snacks for Travel: Ranked From Best to Worst

Not all low treatments are created equal when you're mid-flight, in a foreign country, or deep in a hiking trail. Here's how the most common options actually stack up for travel — ranked from the one I always reach for first to the ones I'd only use if I had nothing else.


When you're at home, treating a low is straightforward. You know where the juice is. You know where the tabs are. You have options.

When you're traveling, everything gets more complicated. You're working with whatever fits in your bag, whatever made it through security, and whatever is actually available where you are. The best low treatment at home is not necessarily the best low treatment on a plane, in a European city, or on a remote trail.

I spent a year traveling constantly through Europe with an Omnipod and Dexcom G6, and I went through enough lows in enough different situations to have strong opinions on this. Here's the ranking.

TSA note: All of the snacks on this list are allowed through airport security. Fast-acting glucose for diabetics is explicitly exempt from TSA liquid restrictions — juice, gel, and other liquids over 3.4 oz can be declared as medically necessary at the checkpoint.

#1 — Sugar Sticks (Single-Serving Sugar Packets)

My top pick, and it's not particularly close. Sugar sticks are the small single-serving packets you see at coffee shops, the ones people tear open and pour into their espresso. Each packet is about 4–5 grams of fast-acting sugar, so three or four gets you to a solid 15–20 grams.

What makes them the best option for travel specifically:

The resupply factor is what pushes these to number one. Glucose tablets run out. Gummies run out. When you're somewhere unfamiliar and realize your low supply is getting thin, you can walk into any cafe and pick up a handful of sugar packets from the condiment counter without buying anything. That kind of accessibility is worth a lot when you're in a foreign country at 11pm.

#2 — Glucose Tablets

Glucose tablets are the most reliable low treatment that exists, and they're excellent for travel. The dosing is precise — usually 4 grams of glucose per tablet — which takes the guesswork out of treatment. You always know exactly how many carbs you've taken.

They're compact, durable, and available in most countries either at pharmacies or online. The tubes are easy to keep in a jacket pocket or the front of a bag.

The reason they're #2 and not #1 is resupply abroad. If you run low on glucose tablets in a smaller European city, finding the exact brand you're used to isn't guaranteed. Sugar sticks you can find anywhere. Glucose tabs require a pharmacy that stocks them.

That said, glucose tablets are the best option for anyone who wants maximum control over treatment dosing. If precision matters more to you than convenience, these are your pick.

#3 — Gummy Candy

Regular gummy bears or gummy candy work well as a low treatment and have a few practical advantages for travel. They're available in virtually every country, they're inexpensive, and most people find them easy to eat when they're already feeling rough from a low.

The tradeoff is precision. Carb counts per piece vary by brand, and when you're dealing with a low you're not always in the best headspace to do mental math on gummies. Knowing your brand's count per piece before you travel helps a lot.

They're also more prone to melting in heat, which matters if you're traveling somewhere warm or doing anything where your bag sits in the sun. A pocket full of melted gummies is not an emergency, but it's annoying.

#4 — Fruit Snack Pouches

Applesauce pouches and similar fruit snack squeezers are a solid low treatment and have become more common as a travel option in recent years. They're fast-acting, come in consistent portion sizes, and most kids' versions have around 12–15 grams of carbs per pouch.

The downsides for travel: they take up more space than the options above, and the pouch format is slightly awkward to deal with mid-low when your hands aren't cooperating well. They also have a best-before consideration on longer trips.

Good option to have in your bag, especially on day trips where you want something a bit more substantial than tablets or sugar packets.

#5 — Honey Packets

Honey packets — the small single-serving ones from coffee shops and diners — are an underrated low treatment for travel. Each packet is roughly 6 grams of fast-acting carbs, they're lightweight, and like sugar sticks, they can often be grabbed for free from restaurant condiment stations.

They rank lower than sugar sticks mainly because honey is messier. A torn packet in a bag is a problem. Honey is also slightly slower to absorb than pure glucose or sucrose, though the practical difference during a mild low is minimal.

Worth keeping a few in your bag as a backup, particularly if you're already carrying them anyway.

#6 — Juice Boxes

Juice works fast and is one of the most effective low treatments by absorption speed. The reason it ranks last on this list isn't effectiveness — it's practicality for travel specifically.

Juice boxes are bulky. Carrying three or four of them adds real weight and takes up meaningful space in a bag. When you're doing a weekend trip with a small pack, that matters. They're also the only liquid option on this list, which means you have to go through the TSA declaration process — not a big deal, but an extra step.

At home, juice is great. On a plane or on a trail, the bulk-to-carb ratio just doesn't compete with the lighter options above. Most airports and convenience stores carry juice anyway, so it's easy to grab on arrival if you want it as a supplement to your existing supply.

What to Actually Carry Day-to-Day

The ranking above is about which options are best for travel overall. On a day-to-day basis while you're actually out and about, the practical answer is to carry a mix:

The goal is to never be in a situation where you're hunting for sugar when you're already low. Pre-positioning a few sugar sticks in every bag, jacket pocket, and day pack means you're covered wherever you are.

Frequently Asked Questions

What is the best snack for low blood sugar while traveling?

Sugar sticks are the best all-around option for travel, particularly in Europe — lightweight, free to restock at any cafe, and fast-acting. Glucose tablets are the best option if you want precise dosing control. The right answer depends slightly on where you're going and how much bag space you have.

Can you bring low blood sugar snacks through airport security?

Yes. TSA explicitly exempts fast-acting glucose for diabetics from standard liquid restrictions. Juice boxes and glucose gel over 3.4 oz can be declared as medically necessary at the checkpoint. Solid snacks like glucose tablets, gummies, sugar sticks, and fruit pouches have no restrictions at all.

How many low snacks should I pack for a trip?

Carry enough for at least 3–4 treatments at any time — enough to handle a low and a rebound if needed. For the overall trip, pack more than you think you'll need and plan to restock on arrival. Sugar sticks and gummies are easy to replenish almost anywhere in the world.

What low snacks work best on a plane?

Glucose tablets are ideal on a plane — no liquid concerns, precise dosing, and easy to keep in a seat pocket. Gummies and sugar sticks work just as well. Juice boxes are allowed under the TSA medical exemption but the bulk makes them less practical for in-seat use.
