Dietary Supplement. Each serving (one teaspoon) of Optimum Nutrition's Creatine Powder supplies 5 grams (5000 mg) of pure Creatine Monohydrate. The patented production method used to produce this creatine yields a tasteless, odorless powder that mixes easily into water or juice and does not readily settle to the bottom. As a result, the gritty taste or texture you may have experienced with other creatine powders is not associated with this product. Optimum Nutrition's Creatine Powder is produced and packaged in our own state of the art manufacturing facility in accordance with current Good Manufacturing Practices (cGMP's).
