Best energy bar overall
Clif Bar gets the best reviews from experts and consumers. These energy bars, which are available in 19 flavors, range from 230 to 260 calories each and get top scores for taste and texture. Clif Bar, which contains 70 percent organic ingredients, also has the best nutritional balance for sustained energy: 40 to 45 grams of carbohydrates and 9 to 10 grams of protein, depending on the variety. Consumers say it holds up well in a backpack without crumbling or crushing, and tastes fine when frozen (some energy bars are too hard to eat when frozen). Clif Bar weighs about 2.4 ounces, so it feels like you're eating a decent portion of food.
