Everyone reacts to gels and chews differently, so it might take a bit of trial and error to determine what works best for you (what doesn’t upset your stomach or what goes into effect the quickest). Everyone has a different absorption rate and sensitivity, and these are all made with varying carb sources and amounts. Honey is used as the major sweetening ingredient in the energy chews, and honey has a compound ratio of fructose to glucose ratio ( 1:1). If you can eat fruit without any stomach issues then you should be fine with these chews.
