Energy bars: In the current bar-wars environment, there are literally hundreds of these prewrapped and potable products competing for shelf space at gyms, health-food stores, and in vending machines, with names ranging from PowerBar and Luna Bar to Balance Bar and Met-Rx. But we believe that not all bars are created equal. There are high-carbohydrate bars, protein bars, energy bars, breakfast bars, brain-boosting bars, diet bars, and women-only bars. And with so much to choose from. We work closely with locations to find out what is the best healthy bars selection for the location.
