flying with supplements in craft boxes
I think you will be fine, too.
I take more than 25 items a day - most of which are nutritional supplements for an autoimmune condition (these have kept me off of steroids, and have kept me able to walk).
There is no way I can deal with carrying (and opening every day) more than 25 bottles, so most of them are set up in two craft boxes, so I only have to open the lids to access all that are in each box. I have flown with these several times. The craft boxes are in the bottom of my backpack and haven't ever been looked at, but it does concern me that I might be given a hard time about this someday.
I haven't flown internationally with this stuff since 2003, so I also wonder if it may now be more difficult to do this on international flights?
