Whey Isolate

The main difference between whey isolate and concentrate is that whey isolate undergoes more processing, which results in a higher protein content with less carbs, lactose and fat. In addition to having lower total carbohydrate content, whey isolate also has lower lactose content. This means that it could be a better choice for those who are lactose intolerant. Whey isolate is typically more expensive than whey concentrate due to the additional manufacturing processes.
