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.
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.

Backed by decades of modern research, WPI supports:
WPI is ideal for anyone with specific fitness and dietary goals:
Best Practice: Space your total daily protein intake evenly across 3-5 meals/servings for optimal absorption and muscle synthesis.
WPI is safe for most people. Excessive intake (far beyond recommended amounts) may cause digestive discomfort. As with any protein, drink plenty of water.
**Always consult your physician before starting any new supplement, especially if you have pre-existing kidney conditions.**
Current research extends WPI benefits far beyond the gym:
