Truvia has erythritol made from corn starch, so I avoid it.
Pure Via is also "Stevia Based" and not totally Stevia.
I grow Stevia on my patio and use it for things like tea. For other things I use liquid Stevia extract, from the health food store. There's just too much junk in the big commercially produced powdered labels, for me to trust them.
ETA: I found this list -
Truvia™ : erythritol, rebiana and natural flavors
Pure Via™ :dextrose, isomaltulose, cellulose powder, Reb A and natural flavors
Stevia in the Raw (individual packets): Dextrose and Stevia Extract (Rebiana)
Stevia in the Raw: Maltodextrin and Stevia Extract (Rebiana)
Sun Crystalsâ : pure cane sugar, stevia.
Stevita™ Spoonable™ : Stevia Rebaudiana Bertoni extract (leaves) and Erythritol.
SweetLeafâ Sweetener™ : Inulin soluble fiber, Stevia leaf extract
Planetary Herbals Stevia Powder: Stevia Leaf (finely ground)
Kal Pure Stevia Extract: Stevia Extract (Stevia rebaudiana) (leaf)
Now Certified Organic Stevia Extract: Certified Organic Stevia Extract Powder (Stevia rebaudiana)(Leaf)
It's OK to be Strong & Pretty! Lift heavy or go home!
