Nature's Best set out to create a product that didn't hide anything from its customers. We wanted you to know that you're purchasing the best product available on the market. Our protein source is clearly identified as 100% Pure Ion Exchange Whey Protein Isolate. We didn't try to confuse you by listing a protein blend that doesn't tell you how much of the product is superior whey protein isolate and how much is whey protein concentrate or sweet whey or some other inferior protein source. Furthermore, Isopure contains 0gm of sugar and is instantized so it can be taken anywhere and mixed with a spoon. Athletes tend to need more protein than sedentary individuals to achieve nitrogen balance. Most recommendations range from 1.5-2.0 grams of protein per kilogram of body weight per day. Isopure will help you achieve the positive nitrogen state you are seeking. It's so pure the protein dissolves clear. Enclosed is a protein sample that will prove you just how pure the protein in Isopure really is. Using a spoon, stir contents of bag into 2-3 oz of water. Let stand for 10 minutes. Please be patient, as ten minutes is needed for the air to escape. The result is a slightly cloudy liquid clear enough so that you can see right through it. The protein used in Perfect Isopure doesn't have the properties typically associated with a milk protein. It doesn't look, smell or taste like milk. We isolated the whey protein molecules and eliminated the impurities to provide you with the purest product of its kind.
