Whey protein (Power Whey) is the cornerstone of our various protein supplements. Whey is a by-product of cheese manufacturing. In its native state, it is approximately 11% protein, 87% carbohydrates (lactose) and 2% fat. It takes nearly 100 lbs of whey to produce 8 lbs of Power Whey. Power Whey is isolated using a very gentle cross flow microfiltration, ultrafiltration and diafiltration process to remove the unwanted components of whey (fat and lactose) and retain the vital components (the protein, including all of its whey fractions). Power Whey contains a generous amount of all the essential amino acids. It is especially high in the branched chain amino acids and the conditionally essential amino acid L-glutamine. There is over 17 grams of glutamine per 100 grams of protein in the Power Whey Isolate.
