OK, so a blogger friend mentioned
AirBorne vitamins for traveling to China. And after reading about it, and hearing that our friends didn't get sick when they went to China, I was sold. The suggested usage is 3 pills per day, disolved in water..so we stocked up for the 12 day trip. I also got some for Cadence, to dissolve in water and put into a bottle. I figure we're going to need all the buffer we can get since we're going to be traveling in winter.
I thought they were chewables, so I popped one in my mouth to test the taste and quality. It started fizzing immediately, and although it tasted like Mountain Dew, the fizz was a bit much.
Note to self: read instructions
first next time.
