If you want natural stevia, get the leaves. They are just as bad tasting to me as any other form I tried but I see no problem with it regarding health…
If you use it very rarely, it’s even less concern.
I typically use sweeteners every day (at least it was like that before my carnivore trials, my future is unsure but I won’t go back to my original keto), I consider erythritol and xylitol okay, the latter is really tasty too (and carbier but we shouldn’t use lots of sweetener anyway. at least it’s my attitude. less is better to me but it doesn’t mean I will give it up. I don’t give up alcohol either and that’s a toxin. but my body handles it and it’s worth it, hands down, despite I don’t need it and I am not addicted to it. I use it rarely and in super tiny amounts. it’s some mental things, not a physical need).
We all have the prerogative to decide about our style, I think.
