Can you bring creatine on a plane? Yes. Creatine is a legal dietary supplement, and you can pack it in a carry-on or a checked bag. What changes from country to country is how much powder you can carry in the cabin and how closely officers look at it.
For most flights, the safest plan is simple: keep the tub sealed in its original container, put it in your checked bag, and carry a small labeled portion for the trip. This guide answers can you bring creatine on a plane for the US, UK, Canada and Australia, with the official sources behind each one.

Can You Bring Creatine on a Plane? The Short Answer
Yes, you can bring creatine on a plane in both carry-on and checked luggage. No major aviation authority we checked lists creatine as prohibited, and USADA states that creatine is not prohibited in sport.
The real question is volume and form. A sealed tub of powder is treated like any other powder, so it can be pulled aside for a second look. Capsules and gummies are simpler. A pre-mixed shaker falls under the liquid rules.
Can you bring creatine on a plane without trouble? Usually, if you plan for three things: how much powder, which country, and which bag. The sections below answer each one.
How Airport Security Treats Powders
Security machines struggle to read dense powders, so officers often want a closer look. That is why flour, protein powder and creatine can all trigger extra screening, even though none of them is dangerous. It is also why can you bring creatine on a plane has a different answer for powder than for capsules.
When a bag is flagged, an officer may ask you to take the container out, open it, or send it through the scanner on its own. British Airways says passengers may be asked to open powders for inspection. TSA says larger amounts “may require additional screening at the central checkpoint.”
Being flagged is not the same as being refused. A powder that cannot be cleared may be kept out of the cabin, and you could lose it, but a clearly labeled supplement in its original container usually passes with little trouble.
Creatine Airport Rules by Country
Can you bring creatine on a plane the same way everywhere? No. Rules differ enough that the same tub can be fine on one route and limited on another.
| Region | Powder rule | Source |
|---|---|---|
| US domestic | No change to carry-on rules; extra screening possible | TSA FAQ |
| Flying into the US from abroad | About 12 oz (350 mL) before extra screening | TSA FAQ, British Airways |
| Canada | 350 mL/g total in carry-on | CATSA |
| UK | 100 mL liquid limit; powders not mentioned on GOV.UK | GOV.UK |
| Australia | Protein powder allowed; declare food items on arrival | CASA, Department of Agriculture |
United States
TSA’s FAQ on powders is where the “12 oz” figure comes from, but the wording is narrower than most blogs suggest. The page says the 350 mL threshold applies to travelers arriving from an international last point of departure, effective June 30, 2018, and that there were no changes to carry-on rules at US checkpoints.
Larger amounts, the page adds, may need additional screening, and powder that cannot be cleared is not allowed in the cabin. The page recommends putting powders in checked baggage, as stated on the TSA powders policy page.
That page dates to the 2018 change, and we found no newer TSA statement. In practice, officers can still ask to inspect any powder, so we treat the 12 oz figure as a sensible limit on every US flight. So can you bring creatine on a plane in the US? Yes, and a checked bag is the safest place for the tub.
Canada
Canada is the strictest of the four. CATSA says protein powder is allowed in carry-on, but powders and granular materials are limited to 350 mL/g or less in total, about the size of a soda can. Checked bags have no limit. So can you bring creatine on a plane in Canada? Yes, but keep carry-on powder under 350 mL.
The same page notes that protein powder does not have to stay in its original container and lists no medical exemptions. You can read the details on CATSA’s protein powder page.
CATSA does not name creatine on that page. We treat it as a similar supplement powder and recommend staying under 350 mL in a carry-on, which is our own conservative reading.
United Kingdom and Europe
The UK government’s hand luggage page focuses on liquids: containers of 100 mL or less in a clear resealable bag at most airports, with some airports allowing up to 2 litres. It does not mention powders, so a creatine tub is not covered by the liquid limit. In the UK, can you bring creatine on a plane? Yes, and the main check is the airport’s own screening.
British Airways explains that its 350 g (12 oz) powder limit applies to flights to the US and that Australia has a similar rule for flights leaving that country. Officers may still ask to open any powder.
We found no official EU-wide powder limit. Rules are set by each airport, so check your departure and connecting airports. If your trip goes through Europe, our guide on whether it is safe to travel to Europe now covers the wider travel picture.
Australia
Australia’s Civil Aviation Safety Authority lists protein powder as allowed in both carry-on and checked luggage, but warns that international arrivals may face quarantine checks. Its page does not state a carry-on volume limit.
The bigger issue is arrival. The Department of Agriculture says travelers must declare food, animal products and plant material on the Incoming Passenger Card or dispose of them. Its pages do not mention supplements by name.
The penalties for false declarations include infringement notices of up to $6,260, so if you are unsure, declare the tub and let an officer decide.
Other Countries
We did not find official, current guidance for Asia, the Middle East or Latin America. Import rules for supplements differ widely, and some countries treat large quantities as commercial goods.

Can You Bring Creatine on a Plane in 2026? What to Know Now
The rules above reflect the latest official pages we could read in October 2026, but several have not been updated in years. TSA’s FAQ page reflects a 2018 change, and CATSA’s supplement page was last modified in December 2022.
That matters because airports are changing. British Airways notes that Heathrow and Gatwick allow liquids up to 2 litres where new screening arrangements are in place, while other UK airports still use the 100 mL rule.
So the question can you bring creatine on a plane also depends on which airport you are flying from. Always check the departure airport’s current page and your airline’s baggage rules before you leave.
Also note a small math detail. Twelve US fluid ounces is about 355 mL, so the 350 mL figure used by many authorities is a rounded number. Staying clearly under it avoids any argument.
Powder, Capsules, Gummies and Drinks Compared
When you ask can you bring creatine on a plane, the form you pack matters more than the brand. The table below summarizes how each form is generally handled, based on the liquid and powder rules above.
| Form | Carry-on | Checked | Main rule | Best for |
|---|---|---|---|---|
| Powder tub | Yes, may be screened | Yes | Powder limits apply by country | Daily use at home |
| Pre-portioned powder in labeled bags | Yes | Yes | Same as powder; keep total small | Short trips |
| Capsules or tablets | Yes | Yes | Solids; officers may still ask | Easiest travel option |
| Gummies or chews | Yes | Yes | Solids; check ingredients | Convenience |
| Pre-mixed drink | Only in 3.4 oz (100 mL) containers | Yes | Liquid rule | Rarely practical |
Powder is the form that draws questions. If you can switch to capsules for a trip, you avoid most of the issues, but check the dose per serving because it often differs from powder.
A pre-mixed drink counts as a liquid. TSA limits liquids in a carry-on to travel-sized containers of 3.4 ounces (100 mL) or less, so a full shaker bottle will not pass unless you empty it first.
Practical Takeaways
Use these steps whenever you ask can you bring creatine on a plane for a new trip.
Keep it in the original container if you can. An unmarked bag of white powder is the item most likely to prompt questions. If you decant, label each bag clearly with the product name and ingredients.
Pack the big tub in checked luggage. TSA recommends this for powders, and CATSA says to pack powders you will not need during the flight in checked baggage. It removes the screening question entirely.
Carry a small portion in your cabin bag. If your checked bag is delayed, a few labeled servings keep your routine going. Keep them well under 12 oz and on top of your carry-on, so you can remove them quickly if asked.
Do not mix it before security. A shaker full of mixed creatine is a liquid. Add water after you pass through the checkpoint.
Athletes should check the label. USADA says creatine is not prohibited, but advises choosing NSF Certified for Sport products to lower the risk of a positive test or other problems. Supplements carry inherent risks.
If an officer stops you. Stay calm, answer questions and show the label. If they cannot clear the powder, ask whether it can go into a checked bag instead of being thrown away.
Know the destination. Declare food items when required and check import rules for supplements before you fly. A tub of creatine is low risk, but rules vary.
Traveling as a family? Keep supplements in a separate labeled bag, away from snacks and children’s items. Our list of the best places for a family vacation in the USA can help you plan the trip itself.
Safety note. This article is general travel information, not medical advice. Talk with a doctor or pharmacist before using creatine, especially if you have a medical condition or take medication.
