Since their introduction a few years ago, Clif Bar & Co.’s Shot Bloks have been among the best-selling nutrition bars in the specialty store segment. Relatively new at mass market outlets, the product has quickly become a best-seller in these stores as well. Designed to provide quick, chewable energy, Shot Bloks come in a bar divided into six individual 33-calorie cubes, making it easy to customize and track caloric and electrolyte intake. Made from 95% organic ingredients, the product is described as having a consistency somewhere between a cereal bar and a gel, making it easier to chew than traditional nutrition bars. Clif Shot Bloks are offered in eight flavors, including orange, black cherry, margarita and citrus.
