From Manufacturer's Label: Creatine monohydrate has been shown to support muscle strength, power, and size when combined with high-intensity activities.** Our Micronized Creatine Powder is made with Creapure®, a creatine monohydrate known for its exceptional purity. It’s also micronized (to make the particles smaller), so our powder mixes easier and stays suspended in liquid longer than non-micronized creatine supplements. • 5g Creatine • 0 calories • Unflavored • 114 servings Manufactured by: Optimum Nutrition
