Can you bring creatine on a plane carry on: Since creatine is not forbidden, you can usually bring it on aeroplanes as a carry-on. Packing it in its original, clearly labelled container, however, is advised to prevent confusion during security checks. Verify the airline's policies and think about packing it in a clear bag for simpler inspection. For a hassle-free travel experience, always follow Transportation Security Administration (TSA) guidelines.
