I've been reading these forums for a few weeks. Some have mentioned taking dextrose or foods high in dextrose in combination with workouts. I find my muscles are sore from exercise ever since starting Atkins so I'm looking to add some carbs before, during and/or after my workouts. My understanding is that dextrose is preferable because it is first used as muscle glycogen. My question is: where can I purchase dextrose (if possible) or what foods are high in dextrose that i can take with a workout?

Any suggestions here are appreciated.
