Thanks, Sophie. There seem to be a few suppliers of Bioextra on Amazon and I'm curious about it. I'll flag the page and hope someone who's used it weighs in with an opinion. If I don't hear anything I'll probably go ahead and order a tube when my current stock of old Biotene runs out in the next month.

And of course I'll be using my OCF link when I do, as always.
