Whey protein isolate is the highest percentage protein you can buy. Whey protein isolates are typically about 90% protein before manufacturers add in flavors or sweeteners. Most whey isolates are fat-free, very low in carbs, and are lactose free. This makes whey isolates ideal for those trying to dramatically reduce carb consumption or bodybuilders trying to cut-up right before a contest.
For kids or adults who are sensitive to the small amount of lactose found in whey protein concentrate, then these lactose-free whey isolates are an ideal choice. From a taste standpoint, compared to whey concentates, whey isolates have a more watery consistency and tend to taste slightly better.
