Perfect Isopure contains 50 grams of 100% pure ion exchange whey protein isolate. Isopure's protein is so pure you can see right through it. It has virtually no impurities. No lactose. No fat. It doesn't look like milk, smell like milk, taste like milk. 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.
