Pocket Protein is formulated from the highest quality collagenic and whey protein “isolate.” The main difference between whey protein and whey protein “isolate” is that isolate is processed further in the manufacturing of whey protein. The end result is a more pure protein, which is lactose free. In fact, over 90% of whey protein isolate, by weight, is protein. That is why Pocket Protein is good through the entire life-cycle. It is good for men, women, kids, teens, millennials, young professionals, middle agers, and boomers alike. POCKET PROTEIN: EVERYONE. EVERYDAY.
