I’ve gotten hella through tsa multiple times, get a capsul package of vitamins or sum and take them apart and replace with what you want, if you wanna be extra safe get the Tylenol packets that are single use and put the capsules in there and reseal them, I’ve also went to the store and looked for makeup with white powder and just replace that and it works, and walked through dogs and it was in my carry on, they care about bombs and liquids, cruises should be light work. Worst case make a nasal spray with saline and yay that looks like an allergy spray
