The packets of stevia I have use inulin (fiber) as a filler, I suppose you would deduct the fiber anyway. I also thought the liquid stevia extract has no carbs.

If you use too much stevia it tastes like licorice but its supposedly very healthy. I cant get used to the taste though, but its probably better than splenda.

Now that I am thinking about fillers, why cant they use inulin with splenda instead of maltodextrin to bulk it?
