Whey isolate is among the purest form of protein available. When you drink a whey isolate powder, you are drinking pure protein…..over 90% protein. That also means that its much lower in fat and lactose, which some people have trouble digesting anyway.Whey Isolate is digested very quickly, which makes it a great protein to use after workouts. It’s an easy protein to drink. It has a very thin consistency and the aftertaste is minimal. I would not use it as much in between meals just because of the speed of digestion.
There are several whey isolate proteins on the market. Some of them are 100% lactose free, which is good for those that are lactose intolerant. The other thing to consider is price. Generally, Whey isolate is expensive, s0 you’re going to pay a pretty penny. Proteins such as ISOPURE from Nature’s Best are the more popular isolates available.
