As a gym junkie who travels a lot, my friends often ask me, “Can you bring protein powder on a plane?” It’s a vital question if you’re traveling on a long journey and the truth is more complex than you might think.
If you bring protein powder on a plane, you're subject to special rules you need to follow.
In this article, I'll cover them all and share what you need to know about protein powder and flying.
Let’s get started!
Are You Allowed To Take Protein Powder On A Plane?
Yes, taking protein powder on planes and packing protein powder into your carry-on or checked luggage is doable. It’s just that there are…certain rules… that could land you in a spot of bother.
Bring protein powder on a plane going to or from America, and you're subject to the Transportation Security Administration. Protein powder shakes are covered on their website too.
It says, “Powder-like substances greater than 12 oz. / 350 mL must be placed in a separate bin for X-ray screening.”[1]
So what does bringing protein powder while following these regulations actually mean for different bags and amounts?
The following sections break it all down, but here's a quick primer if you're short on time.
You'll need a protein powder routine for carry-on and checked bags. It sounds dramatic, but not really!
The rules for protein powder basically ask that passengers going through airport security should be ready for X-ray screening. Meaning a TSA agent wants easy access to your protein powder.
Pour it into a Ziploc or other resealable bag before you get to the airport. Then put it in a separate bin as the rules state.
That’s it - job done!
Now here are the details…
What Are The TSAs Regulations?
For Carry-On Bags
Jamming as much protein powder as you can into your carry-on bag doesn't mean they'll let you board your flight. Tough luck!
Just because you’ve got it with you doesn’t mean transporting protein powder gets any simpler.
If you've got more than 12oz, they'll ask you to put it in a checked bag.
The best way to avoid the hassle is to keep the powder out of your carry-on luggage unless you only have a small amount.
For Checked Luggage
TSA protein powder regulations are much easier to follow with checked luggage. Whether you've got solid protein bars, protein gels, or a liquid protein shake, checked luggage is the best!
Pack protein powder in containers suitable for additional screening and ensure it's not buried in the darkest corners of your checked baggage.
Declare what powdered substances you’re taking to the TSA officer and ensure you follow weight restrictions and other airport security rules. Then you’re good to go!
Bringing Different Types Of Protein On A Plane
Protein Shakes
Whether in a checked bag or your carry-on luggage for your own sanity, make sure these protein meal replacement shakes are SEALED! Any spills from protein shakes at this stage could get messy real quick. Getting a shaker bottle is a great idea.
For convenience, this meal replacement shake bottle should be within reach of the TSA agents in case your security checks demand further inspections of your hand luggage or checked bags.
Protein Bars
Bring protein bars, and you'll have a great time. Additional screening will be a breeze, and your hand luggage will be simple to pack.
Keep them in the original packaging and put them on a separate tray (this goes for all your protein drink powders), and you should be free of suspicion.
Protein Powders (Open and Closed)
Non-essential protein powder has got to go in the checked bags if you’ve got a load of it. Bring multiple containers ready for the security checkpoint in case of inspection.
Resealable plastic bags are best if you don’t have containers for your protein in powdered form. It will make a security checkpoint much less time-consuming for you.
I also recommend keeping your individual protein powder packets closed and in a double bag so there aren’t any accidents. Ziplock baggies will also do.
Protein Gel Packs
Protein gel packs are a quick and easy way to bring your protein powder onboard. No pills to drop, no powder to spill… what’s not to like!
They're still classed under the liquids rule, though, so pop them in a Ziploc bag or another clear plastic bag ready for the screening process.
Protein Pills
Pills have to get looked at for air travel. Who knows what they are otherwise… Food items. Supplements. You get the idea.
Get protein pills ready for the X-ray scanner at airport security by using suitable containers. You know the drill from reading the above!
Can You Bring Protein Powder To An International Flight?
To The UK
According to the UK Government website, "liquids in containers larger than 100ml generally cannot go through security even if the container is only part full."[2]
This limits the amount of white protein powder you can get past airport security in either carry-on bags or checked bags.
Even if you follow the regulations, protein powder will require additional screening. These include being limited to 1 plastic bag per person, which measures 20cm x 20cm.
Best to prepare well in advance if you’re coming to Britain! Keep your protein workout supplement in resealable bags or their original container.
To Canada
Canada's approach for passengers on flights is similar to what the TSA guidelines say. Their CATSA agency has this to say about powdered protein in checked baggage and hand luggage.
"Certain powders and granular materials in your carry-on are limited to a total quantity of 350 ml or less (roughly the size of a soda can)."[3]
So if you've got a large container or many individual packets, double check you can take them all!
To Europe
European Union regulations for air passengers are similar to Britain’s.
Bringing protein powders onto a flight means carrying them "in a transparent plastic bag - maximum capacity 1 liter - and no container may hold more than 100 ml. Liquid containers larger than 100 ml must be placed in checked baggage."[4]
There’s clear flexibility here for passengers taking protein powder in their checked bags. Bear in mind that even a shaker bottle will have to go in checked baggage as it’s still a liquid container.
To Australia
Australia gets quite specific if you're flying with packed protein powder from a foreign country. This is what the Department of Home Affairs says for passengers who bring protein powder in carry-on or checked baggage.
“Inorganic powders must be in containers of 350 milliliters (volume), 350 grams (weight) or less. The total volume of inorganic powders must not exceed 350 milliliters, 350 grams per person."[5]
So when you take protein powder meets both the volume AND the weight requirements!
Common Protein Powder On Plane Questions
No, protein powder doesn't have to be packed in original containers when flying. It should have a label to help identify it during additional checks, though. And it's advisable to keep it separate from other liquids.
The amount of protein powder you can take on international flights or domestic flights depends on the nation and the airline. The best way to find out is to search for information on traveling with protein powder for your chosen route.
In Summary
Bringing protein powder doesn’t have to be a challenge for you! Protein powders generally aren’t viewed with any kind of negativity. You simply have to do what airport security tells you.
Once you know about the size restrictions for traveling with protein powder to your chosen destination, it's a piece of cake!
If you're unsure about protein powder regulations after investigating, then the final decision is always down to the staff at your departure and arrival destinations. Speak to them well before your flight, and you should be fine.
