I have a hard time with straight glucose - I get really wired & then I crash. My advice is to experiment. Cytomax works really well for me, but others on this board have said it wires them. Everybody is different!

The thing about whole grains is that you get vitamins as well as fiber. The fiber helps slow down the release of glucose into your bloodstream. White, processed anything has no fiber and some vitamins added back in - but "ain't nothin' like the real thing baby!"

Lots of people swear by fig newtons - less expensive than power bars and if you can get them at a health food store made with WW flour, probably better for you.
