In a recent email from Hold the Toast,Carbolite Sweetner was discussed...it is "made with sucralose,
like Splenda, but with fiber instead of malto-dextrin as the bulking
agent."
but it has been discontinued...here is a link to the product

quoted from above site
"Carbolite brand sweetener is made from sucralose just like Splenda Granular, but gram-for-gram it is 4 times sweeter than sugar (sucrose) or Splenda Granular.
One half teaspoon of this sweetener is equal to 2 teaspoons of regular sugar or Splenda Granular.
Use it to sweeten your coffee or as a sugar substitute. Each box contains 100 grams.
No Maltodextrin! No Dextrose! 80% Fiber! Zero Carbs.
This product has been discontinued by the manufacturer."
