I used to always fuss about the VSL temperature, and I still do if it would otherwise get hot. If you've got ice or cold packs you need to tell TSA you've got "medical liquids." I prefer regular ice in ziplock bags so I don't need to carry it home. At a hotel I sometimes just use the ice bucket in the room.

 

VSL is fine for up to a week at room temperature, if you trust that your pharmacy has kept it cool.

OK, thanks for the tip.  I figured they will ask about the ice pack. Maybe it makes more sense to load some ice cubes in a ziploc.  I will do that instead.

You could also just buy the standard VSL-3 in Tampa for about $55 from a pharmacy.  This way you don't have the hassle of transporting it.  Up the dose of the standard VSL to the DS strength and you'll use up all of the probiotic while you are there for the short vacation.

So I found that Scott's suggestion worked really well. I packed ice cubes in a one gallon ziplock bag and placed them on top of the VSL#3 DS packets in my Artic Zone thermal bag and then stuffed the bag in my suitcase around 4:15 am. I left for Hartford around 4:30 am. Flight took off around 7:30 am and we landed in Tampa at 10:30 am. When I unpacked in Bradenton at around 12:30 pm the ice had barely melted, this despite 84 degree Fahrenheit temperatures in Bradenton at the time. I then threw the VSL in the refrigerator. It worked well.
