Creatine monohydrate powder in a labeled tub

Yes, creatine clears TSA in carry-on and checked bags. The rule that governs it is TSA's powder threshold: anything over 12 oz / 350 mL goes in a separate screening bin for a closer look, not confiscation. A week's supply, about 35 g in a labeled container, sits well under that line and normally needs no extra step.

Creatine is one of the easiest habits to keep at home and one of the easiest to second-guess at a security line. It's a fine white powder in a tub, which is exactly the shape TSA built a rule around, so the question comes up every time someone packs for a trip. The actual rule is short enough to just read.

What's the actual TSA rule?

TSA's own language is specific: powder-like substances greater than 12 oz / 350 mL must be placed in a separate bin for X-ray screening, and officers may open the container for a closer look.[1] Powders under that line don't need a bin of their own, though TSA can still screen or open any container it wants a closer look at. There's no quantity cap on powders in checked baggage at all, so a full tub or a bulk bag travels the same way.[1][6]

Creatine isn't a liquid, so the familiar 3-1-1 rule for liquids and gels doesn't apply to it. The 12 oz / 350 mL powder threshold is a separate allowance, and it's the one that actually governs a tub of creatine.[1]

The rule started in 2018, aimed first at flights into the US, and the "soda can" comparison comes from that rollout: 12 oz / 350 mL is roughly the size of a standard can.[5] TSA's current guidance applies the same threshold generally, not just on that original route.[1]

Here's the part worth being precise about: the "oz" in TSA's limit isn't the same kind of ounce as the "oz" people usually picture. A soda can is sized in fluid ounces, a measure of volume, which is why 12 oz / 350 mL reads naturally as "about a can."[1][5] AUROM's tub, by contrast, is described by the weight of the powder inside it, 250 g, not by volume. Converting a weight to a volume means knowing how densely the powder sits in the container, and none of the sources below publishes that figure for creatine monohydrate. So the honest answer is this: you can't check a full tub against the 12 oz / 350 mL line just by reading the label. The packing advice below holds either way.

Carry-on or checked, which is simpler?

Checked is simpler if you're bringing a full tub. There's no quantity cap on powders in a checked bag, so a full 250 g tub, or more, goes in without a second thought.[1][6] Carry-on is simpler if you pack a smaller amount: a travel container with a week or two of scoops is comfortably under 12 oz / 350 mL by any measure, and TSA has no quantity objection to it, though any powder can still get pulled for a closer look at an officer's discretion.[1][6] A full tub in a carry-on is the one case worth planning around: no published figure gives its volume, so there's no way to know ahead of time whether it clears the 12 oz / 350 mL line or lands in the separate screening bin. Either way, being over the line just means a separate screening bin, not confiscation.[1]

Either way, a TSA officer makes the final call on anything that reaches the belt, and a powder that can't be cleared doesn't fly in the cabin.[1][6] Keep it in the original tub, or a travel container that's clearly labeled, rather than an unmarked bag. A printed label makes it easy to identify as what it is, which is one less thing to explain if anyone asks.

Flying outside the US?

Canada's rule is close to the US one, just stricter on the number. CATSA limits certain powders and granular materials in carry-on to a total quantity of 350 mL or less, states there are no exemptions for medical reasons, and publishes no quantity restriction for checked bags.[2]

The UK doesn't publish a numeric carve-out the way the US and Canada do. GOV.UK's guidance is that food and powders can obstruct the X-ray image and your bag may need to be checked again manually, and that staff won't let through anything they consider dangerous even if it's normally allowed in hand luggage.[3] If you're flying out of the UK, or connecting through it, a checked bag avoids the question entirely.

Across the three rules above, one thing holds everywhere: checked baggage is the simpler option. The US and Canada publish a numeric carry-on threshold, and the UK doesn't, leaving it to a manual check and the officer's judgment.[1][2][3] Other countries set their own rules, some with a numeric limit and some, like the UK, on officer discretion. If you're connecting through a country you haven't flown from before, checking that country's own aviation security page before you leave costs a few minutes and settles it ahead of time instead of at the belt.

How much creatine do you actually need to bring?

This is where the AUROM math works in your favor. One scoop is 5 g, and a full 250 g tub is a 50-day supply at that dose. A week of travel is 7 scoops, 35 g, which fits into a small zip bag or travel container with plenty of room to spare, and 35 g of powder is well under 350 mL no matter how you measure it. That's the version to pack if you're carrying on: comfortably inside the rule, and clearly what it says it is.

If the trip is longer, or you'd rather not measure out scoops, bring the whole tub and check the bag instead. Those 250 g of powder come to about 8.8 oz by net weight, but checked baggage has no published quantity cap on powders in the first place, so neither its weight nor its volume matters there.

Does the tub itself make this easier?

Single-ingredient creatine monohydrate doesn't need an argument at the counter. There's no proprietary blend to explain and no mystery mix, just a printed label that matches what's inside. Every batch of AUROM's creatine monohydrate comes with a Certificate of Analysis available on request, which is a good thing to have handy if anyone asks what's in the tub, though in practice a label that just says "creatine monohydrate" tends to settle it on its own. The product page lists the same 5 g scoop used in the math above.

A few packing notes that actually help

Leave the label on. Whether it's the original tub or a travel container, a readable label that says "creatine monohydrate" makes it easy to identify at a glance.
Bring the scoop, or don't bother measuring. A loose scoop rattling in a bag is a minor annoyance, not a security issue. Some people just eyeball a spoonful for a short trip instead.
Split it if the trip is short. A travel container with a week's worth, 35 g, is clearly under the 12 oz / 350 mL carry-on line, and easier to explain if anyone does ask.[1]
Keep the Certificate of Analysis handy if you want it. None of the US, Canadian, or UK guidance above asks for documentation of a supplement's contents, so it isn't required.[1][2][3] It's still one more piece of paper that says exactly what's in the tub if you're ever asked.

What if the trip breaks your streak anyway?

Say the tub clears security without incident and you still skip three days because you're on a plane, in a different time zone, or just off your routine. That matters less than it feels like it should. Creatine builds up in muscle slowly, and it drains slowly too: once your stores are saturated, they take roughly 4 to 6 weeks to fall back to baseline if you stopped completely, and there's no evidence they ever drop below where you started.[4] A missed day, or three, on one trip is nowhere near that timeline.

We've written the longer version of this at missing a day of creatine: the short version is that your stores fall slowly enough that a travel gap doesn't undo weeks of daily dosing. What actually matters is getting back on schedule once you land, and if you want the exact math on how long a tub carries you through that, how long a tub of creatine actually lasts walks through it.

Questions people actually ask about flying with creatine

Will TSA confiscate my creatine? Only if it can't be cleared during screening: the TSA officer decides, and a powder that fails screening doesn't fly in the cabin, which isn't the same as being confiscated. Powders over 12 oz / 350 mL go in a separate bin for a closer look, which is extra screening, not automatic confiscation.[1][6]

Does creatine count as a liquid for the 3-1-1 rule? No. Creatine monohydrate is a dry powder, so it's screened under the powder rule, not the 3-1-1 liquids rule.[1]

Can I bring an unlimited amount of creatine in a checked bag? As far as published guidance goes, yes. TSA and CATSA both allow powders in checked baggage without stating any quantity limit, and TSA actively encourages sending powders over 12 oz there. GOV.UK publishes no powder quantity rule at all, for hand or hold luggage.[1][2][3]

Should I keep it in the original tub, or can I move it to a travel container? Either works for the rule itself. A labeled container, original tub or a clearly marked travel container, is easier to identify and easier to explain than an unmarked bag of white powder.

Does it matter if my flight connects through another country? It can. Each country's security agency applies its own rules at its own checkpoints, and they don't match, so a connection through a second country means clearing that country's rules too, not just the one you started in.[2][3]

The TSA question has a short answer. What's actually worth your attention is getting back on schedule once you land. Pack a week's worth in a labeled container, or check the tub if that's easier. Neither one is worth worrying about on the flight.
