I just received some free samples of this stuff in the mail today. I've been wanting to try it for a while now, but didn't want to spend the money on a whole tube in case I didn't like it. So as I was looking at the ingredients on the package, I was disappointed to see "Sorbitol" listed...

Ironically, on the front of the package, it says "Naturally Sweetened" (it's primary sweetener is stevia)...but what is so natural about Sorbitol? I have GI issues with sorbitol, which is why I had to stop chewing gum as nearly every brand of sugarless gum uses either sorbitol, mannitol, or xylitol as a sweetener. Oh well...I guess if I had taken the time to read the ingredients online, I would have known this already. I think I'll stick with using the ZYM Rival Orange tablets, as it contains no sugar alcohols, only stevia.
