If you are traveling with melatonin oil, you don’t need to worry about the size of the bottle, but you should only bring a reasonable quantity.

You will also need to inform the TSA officer at the security checkpoint that you are carrying liquid medication, and you will need to remove it from your bag for screening.

Even melatonin aromatherapy vaporizers are permitted through the security checkpoint.

Yes, you can bring melatonin gummies in a checked bag without any issues, and you do not need to declare medication at the airport.

However, it is generally not recommended to place medication in checked baggage.
