Dextrose for a drink mix

I seem to remember a TR podcast that mentioned Dextrose as a good place to start in building my own sports drink for on the bike. I cannot find the episode of the podcast that this was mentioned and would appreciate some guidance. There also is not any written information when I searched here.

Also does anyone make their own mix using dextrose and if so what is your favourite recipe? BTW dextrose is very very sharp.

Dextrose is mentioned in several threads. Below are the ones related to general use/consumption and making your own.

Its super easy. I make gatorade from powder, then just add dextrose until I’ve got as many calories in the bottle as I’d like.
