I usually purchase my pre-workout supplements at my destination. However, many fitness enthusiasts wonder if they can bring their supplements on a flight. The good news is that it is possible to travel with supplements, so let’s review the TSA regulations.

Can You Bring Pre-Workout on a Plane?

The quick answer is Yes. The Transportation Security Administration (TSA) guidelines permit pre-workout supplements in both carry-on and checked luggage. However, powders in your carry-on should be kept in containers no larger than 12 ounces or 350 millilitres.

Containers larger than this may be subject to additional screening. If you’re carrying larger amounts, packing them in your checked baggage is a convenient alternative.

Carry-On Bags

You are permitted to bring pre-workout powders in your carry-on bag. If the quantity exceeds 12 ounces or 350 millilitres, remove it from your bag and have it screened separately. It is advisable to store the supplement in a clear, resealable bag for easy inspection.

Checked Luggage

To minimize the risk of spills, ensure that your pre-workout container is airtight.

Additionally, pack the pre-workout in the centre of your checked bag. This provides extra security against shifting and potential damage.

Additional Recommendations

  • Keep your pre-workout in its original container if possible. This can ease the inspection process and prevent any misunderstandings about the contents.
  • Label your supplements clearly.
  • If travelling with a larger quantity, be prepared to have it screened separately at the security checkpoint.

Essential TSA Rules

  • Solid supplements don’t need extra screening.
  • Powders over 12 oz. / 350 mL may require additional screening.
  • Liquid restrictions don’t apply to powdered substances, but rules on quantity and packaging are in place.

Does the 3-1-1 Rule for Carry-On Luggage Impact Preworkout Transport?

Yes. The 3-1-1 regulation impacts the way you can carry liquids, gels, and aerosols in your carry-on bag to ensure security.

Here’s a breakdown of the 3-1-1 rule:

  • 3: Liquids must be in containers that hold 3.4 ounces (100 millilitres) or less each.
  • 1: All these containers must fit into one clear, quart-sized, resealable plastic bag.
  • 1: Only one bag per passenger is permitted in the carry-on luggage.

Remember to declare any larger quantities of supplements to the security officer for inspection.

A man's hands are visible, one hand is holding a container of pre-workout supplements, and he appears to be contemplating where to place it in the suitcase. The pre-workout supplement container is medium-sized, cylindrical, with a bright label that stands out among the clothes. There's a distinct contrast between the warm clothes and the cool metallic exterior of the suitcase. The sunlight casts shadows over the scene, creating a warm ambiance.

If you are planning to travel with your pre-workout supplements, keep the transport regulations in mind when packing. Here are some tips on how to pack your pre-workout supplements.

Packing Preworkout in Checked Luggage

Pre-Workout in Capsules or Tablets: You can pack your pre-workout capsules or tablets in your checked luggage without restriction. However, have them in their original packaging to avoid confusion during screening.

Pre-Workout Powders: You are allowed to include them in your checked bag. There’s no limit to the quantity, but packages over 12 oz may be subject to additional screening by the TSA.

Packing Preworkout in Carry-On Luggage

Under the 3-1-1 Liquids Rule: Liquids, including mixed pre-workout beverages, are subject to the TSA’s 3-1-1 liquids rule. To comply, ensure any pre-mixed liquid is in a container of 3.4 ounces or less, and all containers must fit in one clear, quart-sized bag.

Pre-Workout Powders: You can also bring pre-workout powders in your carry-on. Quantities under 12 ounces won´t be removed from your carry-on for screening. For amounts exceeding 12 ounces, place the powder in a separate bin for X-ray examination.

Domestic vs. International Flight Regulations for Pre-Workout Supplements

Domestic Flights in the USA

For domestic flights within the United States, passengers can carry pre-workout supplements classified as “Protein or Energy Powders” by the Transportation Security Administration (TSA).

If the powder quantity exceeds 12 oz./350 mL, it must be placed in a separate bin for X-ray screening, while amounts less than this threshold can remain in your carry-on bag during airport screening.

Containers may be subject to opening and additional screening by airport staff. To avoid inconvenience, larger quantities should be packed in checked luggage​​​​.


Similar to the U.S., up to 12 oz./350 mL of powder-based supplements can be brought in carry-on luggage. Larger quantities should be placed in checked luggage to avoid delays during screening.

It’s recommended that mineral-based supplements, regardless of the amount, be checked to adhere to regulations​​.

European Union (EU)

The EU does not impose specific restrictions on carrying powder supplements like pre-workouts on flights.

However, airport security may require additional screening regardless of the amount. To minimize potential disruptions, placing them in checked luggage is advisable​​.

United Kingdom (UK)

There are no specific restrictions on travelling with powdered food items, including pre-workout supplements, in the UK.

However, to avoid hand checks by security, which may cause delays, it’s suggested to pack them in checked luggage​​.


Domestic flights within Australia do not have restrictions on carrying pre-workout powders. However, for international flights, restrictions apply.

Inorganic powders, like pre-workouts, must be in containers of 12 oz./350 mL or 350 grams or less.

The total volume of inorganic powders must not exceed 350 mL/12 oz. or 350 grams per person. Powders must be presented separately at screening but do not need to be in a resealable plastic bag​​​​.

Middle East and Turkey

Travellers in the Middle East and Turkey can carry supplements, including pre-workouts, in their carry-on luggage without restrictions.

It is recommended, however, to keep them in their original containers to avoid potential screening delays​​.

General Tips for All Flights

  • When carrying powdered supplements like pre-workouts, keeping them in their original packaging or a clear, labelled container can help smooth the security process.
  • If the supplement is in liquid form, it must comply with the 3-1-1 liquids rule (containers of 3.4 ounces or 100 millilitres or less, all fitting in a single, quart-sized, zip-top, clear plastic bag) for carry-on bags​​.

Risks and Precautions when Bringing Preworkout on a Plane


  • Confirm Quantity: Adhere to the TSA’s 3-1-1 rule for liquids and gels.
  • Powdered Substances: For powders, you can bring a container of up to 12 ounces (350 millilitres) in your carry-on without additional screening. Containers larger than that may require additional screening.

  • Misinterpretation: There’s a risk that pre-workout substances can be misconstrued as something illicit. Ensure your pre-workout is in its original packaging or clearly labelled to avoid confusion.
  • International Restrictions: Some countries have different regulations concerning the transportation of supplements. Before travelling internationally, check the destination country’s policies on these substances.
  • Leakage or Spillage: If you’re carrying pre-workout in liquid form, there’s a potential for it to leak or spill. Use leak-proof containers and be mindful of how you pack them to avoid damage to other items in your luggage.


In conclusion, you can carry pre-workout supplements on the plane. However, you should adhere to TSA guidelines: limit powder to under 12 oz/350 mL, pack in a clear bag for easy X-ray screening, and place larger quantities in checked luggage.

Liquid supplements must comply with the 3.4 oz (100 mL) rule for carry-ons. Always check specific airline and destination rules to ensure smooth travel with your supplements.
