I've never had a problem with sucralose, not even a hint of trouble. And none with maltodextrin either. My body just thinks it's starch. But sugar alcohols like maltitol and all the other -ols give me cramps, bloating, and the runs if I eat very much. Sugar-free Hershey bars have a reputation as a super-laxative because of it. Maltitol has such a bad effect on so many people that Haribo quit making sugar-free gummy bears. And Jelly Belly said a serving of sugar-free ones was 32 of those tiny beans, but suggested you only eat 6 of them the first time, to see if you can tolerate it.
