It's the purest of all meal replacements. When you mix Isopure with water (a spoon will do, a blender isn't necessary) it will look a little cloudy. That's because while the protein is pure, we've added 25 grams of carbohydrates, 4.67 grams of L-Glutamine and a burst of vitamins and minerals. Nature's Best set out to make 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 caseinate or some other inferior protein. Furthermore, Isopure contains only 1g of sugar and is instantized so it can be taken anywhere and mixed with a spoon. Professional teams and athletes are making Isopure their product of choice, including the New York Jets... "During the 1998/1999 football season, we will be using Perfect Isopure. It is the highest quality, most convenient product we have ever been exposed to." - John Lott, Strength and Conditioning Coach, New York Jets.
