Ripple Shake Ups were developed specifically for kids ages six and up. Each Shake Ups carton starts with a milkshake taste kids love and provides 13 grams of plant-based protein and 3 grams of fiber to help keep kids full. Our regular protein shakes are designed for adults and contain 20 grams of protein in an 11 or 12-ounce serving. The 8-ounce Shake Ups cartons are the perfect size for kids' lunch boxes and backpacks. Plus, we included essential vitamins and minerals for growing bodies, all in a bold, fun package that kids will love.
