Can you take Optimum Nutrition Creatine Monohydrate Powder on a plane?
Supplement · counts as powder
Creatine powder is fine in your cabin bag at any size. The 600g and 1.2kg tubs will likely be swabbed at US airports — that's normal.
Rule basis: Sizes sold: 300g tub, 600g tub, 1.2kg tub.
What to do: Cabin: containers ≤ 100ml. Checked: any size.

In cabin baggage
Creatine is a fine, white powder. It's allowed in cabin baggage at any size — but a 600g+ white powder tub will almost always trigger an extra screening at US airports. Pack it where it's easy to take out of your bag.
In checked luggage
creatine powder travels fine in checked luggage. No leak risk worth worrying about, but pack it in a toiletry bag so it doesn't pick up clothing odours.
Real-world examples
- •300g tub: cabin OK, may be swabbed in the US
- •600g / 1.2kg tub: cabin OK but expect an extra screening — easier in the hold
- •Decant into a 350g pouch to dodge the US powder rule
FAQs
Is creatine a TSA liquid?
No. It's a powder. The 100ml liquids rule doesn't apply.
Will I be flagged for travelling with a 1kg tub of white powder?
You'll likely be asked to step aside for a powder screening at US airports. Officers will swab the tub and the bag. It usually adds 2–3 minutes and you keep the powder.
Any countries where creatine is banned?
Not pure creatine monohydrate. Pre-workout blends sometimes contain ingredients banned in the UAE, Saudi Arabia, Japan or Singapore — check the label.
