This stuff is equimolar sugar molecules and sodium molecules that co-transport accross the gut endothelium and osmotically pull water. The overall concentration of salt to water is similar to plasma. Its like drinking an IV bottle. It goes right into the circulation. Works well even if you're puking your guts out or spewing out your butt like a banshee. Kicks ass for hangovers like you wouldn't believe. Way cool. This could saves a bazillion lives in third world countries if people would use it.
