The sweeteners at this time in the Jigsaw Electrolyte Supreme are erythritol, stevia and monk fruit extract and in general, anecdotally-speaking, so far people who reject erythritol and/or stevia do so because of taste and not because of an insulin response so in the quantities per serving they’re not likely to be an issue (there are certainly exceptions).
I personally like an erythritol/stevia blend. I have less experience with monk fruit extract, but if I recall correctly it is one that Maria Emmerich recommends, so it’s probably okay.
That being said, everyone has a different response to sweeteners because part of it has to do with the cephalic release of insulin which is more of a conditioned/learned response and less about biology, so they could trigger an insulin response as well as cravings.
Personally I didn’t have this trigger cravings in me which is why I would consider using it for variety over drinking salted ACV water or the Keto-ade mentioned elsewhere in these forums. …I just get bored drinking the same thing over and over again.
