Quest bars at bodybuilding.com and GNC have plenty of protein and no added sugar. Choose the flavors which are sweetened with stevia instead of sucrolose. Legionathletics.com has protein bars with a few more calories and they too are better than the commercial brands made bu General Mills and the like. Stay away from G bars. They have more added sugar such as HFCS that protein because they are made by Gatorade which is owned by Pepsi.
