Looking to make my own carb drink for the bike, and curious what the big differences are between these three. I know dextrose is just d-glucose, maltodextrin is a linear chain of glucose molecules, and Waxy Maize is a branched chain starch. So I get that it mainly boils down to breakdown rate in the…

I believe the long chains like maltodextrin are more soluble in water vs the shorter ones, making it easier to fit hundreds of grams in a bottle. Try that with sucrose and you end up with a slurry, not a liquid.

I just use dextrose. Maltodextrin is the same performance-wise but malto doesn’t mix as well…it’s a lot harder to cram a lot of calories into a single bottle with malto than with dextrose. Starch doesn’t mix very well at all. Also, you will suffer a performance penalty if you fuel with starch vs …
