Yes, PureVia as a zero calorie sweetener is definitely good; the all natural factor, using Stevia, is definitely a plus in that it's healthier.  No weird taste in my food & no aftertaste, at least I didn't taste one, but then I've been using stevia as a sweetener for quite some time now, so I may just be used to it.  My children don't like the taste of stevia products, but they found PurVia to be much better than others they've tried.
