CytoSport Inc., the maker of Muscle Milk, introduces Evolve, a naturally flavored protein shake. Evolve can be found in the weight management or protein nutrition aisle at retailers nationwide. Packaged in a convenient, 8.25oz carton, Evolve is sweetened with stevia, cane sugar and monk fruit. Officials say Tonalin CLA, an ingredient in Evolve, helps reduce body fat, maintains lean muscle mass and improves body composition. CLA (Conjugated Linoleic Acid) is a polyunsaturated, conjugated fatty acid that is a natural part of the human diet, found primarily in meat and dairy products. Tonalin CLA is an exclusively licensed product of BASF Personal Care and Nutrition GmbH. Evolve is lactose- and gluten-free and contains only 110 calories, including 12g of protein, 20 vitamins and minerals, and it is an excellent source of fiber. Evolve is available in five flavors: Chocolate, Vanilla Crème, Strawberry, Mixed Berry and Café Latte.
