1. What is Whey Protein Isolate?

Whey Protein Isolate (WPI) is the purest form of whey protein available. Through advanced filtration, it’s stripped of most fat, lactose, and carbs, resulting in a product that is typically 90-95% protein by weight.

What will Whey Protein Isolates do for Me?

Scientists have confirmed this revolutionary super protein to yield a higher bi-availability than any other protein source in existence. This superior bio-availability can mean greater nitrogen retention, greater protein synthesis, and ultimately dramatically improved muscular growth! All this with better taste and easier digestion.
