Q: I'm a regular stevia user, but this is the first, last, and only time I'll use this product -- or any stevia product that is artificially flavored or extracted with alcohol. The chemical aftertaste from this product was overpowering and distasteful. For a better stevia product, try SteviaClear by SweetLeaf -- the only stevia product I use.

Negative
