Maltodextrin is a glucose polymer (string of glucoses chemically hooked together). The rate of transfer of glucose across the intestinal wall into the blood stream is apparently dependent upon the concentration of glucose in the intestine. Maltodextrin breaks down into glucose at a rate that that maintains this concentration.
However, recent studies have indicated that the total carbohydrate rate is enhanced by having a second simple sugar (fructose) present. I have not yet found a good source of fructose to add to my water bottles along with the matlodextrin.
Also, as another poster mentioned, you need to find a way of getting any needed electrolytes. I add salt and 'low sodium' salt to the mix to get sodium a potassium. For calcium - a couple of Tums. Still looking for a magnesium source.
