Though glucose is better than fructose, there's still enough credible concern out there about spiking glucose levels and insulin issues that your self-treatment may not be the boon you think it is.

In any case, a lot of formed and powedered candies are almost pure 'dextrose' -- so you don't need to go to industrial suppliers. Just grab some Sweetarts/Lik-M-Aid/PixieStix. (No corn syrup is listed on the ingredients of these, but sometimes 'maltose' is. It's two joined glucose molecules, but I don't know if it splits cleanly to that and only that in the body.)
