Protein Powder — TSA Rules Explained

You can bring Protein Powder in your carry-on bag, but certain conditions apply. It is also allowed in checked baggage without restrictions. Protein Powder is allowed with conditions in carry-on bags — Containers over 12 oz (350g) may require additional screening. Powder supplements are allowed but may require extra screening if over 12 oz. TSA officers have the final say on what is allowed through the checkpoint. If you are unsure, check the TSA website or ask an officer at the airport.

How to pack protein powder to speed up screening

  • Measure single servings into clear zip bags or a labeled shaker — small, clear portions screen faster than a large opaque tub.
  • Keep powder in the original container with the nutrition label when you can; unlabeled bulk powder draws the most scrutiny.
  • Put powders in an outer compartment so you can pull them out for a separate bin without unpacking your bag.
  • Containers over 12 oz may be opened and swabbed — allow a few extra minutes at the checkpoint.
  • Checked baggage has no powder screening limit, so large tubs belong there.

If your powder is flagged at the checkpoint

  • The X-ray image of dense powder is hard to read, so your bag may be pulled for a manual check.
  • An officer may open the container, swab it for explosive traces, and reseal it.
  • If the powder cannot be cleared, you may be asked to surrender it or check the bag.
  • International outbound flights can apply stricter powder rules than U.S. domestic screening.
